Betty asks…

Help With VNC Client?

ive been going through Faq’s and documentations but i cant seem to figure out how to connect to my VNC Server
i need to know everything there is to know about VNC
i.e what do they mean by host name.
i just need steps on how exactly to set it up
Using Tight VNC

admin answers:

The host name is the computer name of any machine. First you need to install vnc on the machine you want to control. Then either start the vncserver from the start menu, or use the admin tab to install it as a service, this way it runs every time the machine starts. When started the first time it will ask you to set a password. You then need to open the appropriate ports in the firewall. 5800 for the browser based connection, 5900 for the client based connection. Install it on your own machine. You then run the vncviewer from the start menu, enter the “host name” of the computer you are connecting to, or alternatively it’s ip address.
When the connection succeeds you wil be asked for the password. The other way is to open your browser and enter http://hostname:5800, again the ip address can be used. This will again ask for the password. Be careful, if you had to ask about the hostname you are obviously inexperienced, you can trash the remote machine if you get careless, as easily as you can your own if you touch system files.

John asks…

How can I get VNC to work right on our LAN?

We just got a new Netgear WNR3500L for our network, and we’ve just set up a media center PC. I’ve installed Mythbuntu on it, and I want to be able to control it from my Ubuntu computer. I’ve tried several VNC clients, and have properly set up VNC on the targeted PC, but whenever I try to connect, it says “no route to host, unable to connect”, and it’s frustrating. Is there anything I can do?

admin answers:

Are you using the internal ip address? You have to open up a port or use UPNP if you are using the external address.

If you are using internal, maybe try to telnet to that port, see if it is truly listening or not. Might need to disable any firewalls if u have one.

Laura asks…

NEED VNC SOFTWARE (able to build client applications; excluded Remote Support System, TeamViewer)?

I need a software which allows you to control client computers. The software should be able to build its client application: introduce ip, port [, proxy settings] [, usr, pwd], maybe able to detect proxy settings at runtime / to allow client-side proxy configuration.

freeware software is a best choice

please do not answer with TeamViever (www.teamviewer.com), Remote Support System (http://www.remotesupportsystem.com), VNC‘s that require server installation / deployment / unzipping and configuration, applications which require a internet browser, applications which use online services.

best answer (based on workability of the application) will get what it deserves.

do not bluff, you will be bad-rated.

thanks
guess what: noone even mentioned UltraVNC SC (single-click) used by ……….. which has a built-in repeater, a nat2nat translator etc etc etc

you just customize the server part (add all the needed details), give it to the client and start your vnc client in listen mode on a specific port.

when the client launches the server, the server itself tries to connect to the ip and port specified wihthin at build time.

guess what: noone gets a “best answer”

no good answers for question http://answers.yahoo.com/question/index?qid=20061218015429AAveRA1

Reposting question:

I need a software which only needs to be installed on my computer and which allows you to control client computers. The software should be able ( !!! CRITICAL FEATURE !!! ) to build its client application (exe file that you send to the client) which should include my ip address, the port number that my server is configured to listen to, eventually user and password.

applications should be like Remote Support System 1.7.1

freeware software is a best choice

please do not answer if you want to recommend me TeamViever (www.teamviewer.com), Remote Support System (http://www.remotesupportsystem.com), VNC‘s that require customer-side server installation / deployment / unzipping / configuration, applications which require a internet browser, applications which use online services.

Linda asks…

VNC Free Edition 4.1.2 not working… I can connect to myself on both computers, but not to each other?

anyone know what the problem could be? both computers are using firewalls. i tried connecting to the same computer using the VNC server, and it worked, however,

when i use the other computer to connect to this server, it wont work. i tried using the IP, and the computer name, it works with the computer name, but not when trying to connect to each other
ah, they do both have the same IP. is there a way to fix this?

admin answers:

Make sure both computers don’t have the same IP address if they do they won’t connect. What happens is the comp will think it’s trying to connect to it’s self hence the different IP

Your Questions About Real Vnc

Sandra asks…

Does anyone know how to use Real VNC?

I live in california, I am trying to connect to my cousins computer in chicago. We are both behind a router and I can’t get a connection on both computers. Can anyone help?
I am a beginner at this, one of my friends told me about this software, but then he moved away and never got a chance to help me with this software.

admin answers:

Routers have nothing to do here, it helps to route your IP pachets.
First you have to ping the IP of your cousins. If you receive an reply, it is a good sign.
Then you have to act as a client , with VNC Viewer. Start it and when it’s requesting host, type their IP address ( I suppose you have it !). Be aware if you have firewall activated on your PC ( or their PC) , it might block you !
Remote PC should have VNC server installed and configured ( usual it requests for a access password ). A small icon on lower-right corner ( on taskbar ) with Vnc shows if server is active. If your VNC Viewer contacts the server, it will require you the expected password, if not, you have to check VNC server settings.

This was a short explanation ! I didn’t know how familiar are you with IP stuff !

Laura asks…

How can I have Real VNC start up with XUbuntu (Linux) 9.04?

Joseph asks…

How do I setup Real VNC?

I need to set up Real VNC software (www.realvnc.com) to control my PC at home from my PC at school (orlando and Miami). Both are on DSL, nothing too complicated. The instructions on RealVNC’s site are SOOO confusing! I can’t seem to get it right! Someone please help me do this!

admin answers:

I am assuming that you have some sort of hardware firewall between the DSL modem and your network. Given that, you’ll need to figure out how to do “port forwarding” to the IP address of your computer (need to have a static IP address on your computer) of traffic on Port 22, TCP/IP.

John asks…

Trying to connect with real vnc?

Ok I have real vnc on my home computer and the work computer already had it. I am trying to connect to the computer at work from home. I have my ports forwarded correctly and i did a test at the real vnc website and it said it was fine. So what do i have to do to connect? I used the viewer and put in my work computers external ip, but connection timed out. Also when i hover my mouse over the vnc icon on my home computer it says my local ip, not my external.

admin answers:

U have to have the vnc server runningon both computers, also if your going through a router u have to port forward them to the internal ip adress that might be the problem… If u use the external ip adress and its on router with multiple computers which computer will it know to connect too?? Its been a while since ive configuread a vnc so i might be wrong, if so someone plz correct me..

Steven asks…

FireFox?????

okay so i downloaded firefox. i’ve been using firefox for a while, and all a sudden when i x’ed out my firefox and opened it again it wont go to websites, it wont even say page not displayed. it will just be blank. so i unstalled it and re stalled it and it worked when it was launched from the reinstal but when i x’ed it out again and opened it it showed blank. does anyone know how i can fix this????

admin answers:

Mine alwayz goes
Page cannot be displayed it took to long to load
ALOT!
But its better than Explorer!

Mark asks…

FireFoX????????

I always hear that Fire fox is better than Internet Explorer and its faster safer ect….But what are the bad things about firefox?

admin answers:

I really don’t know of any bad things, since it’s open source. The only complaints I have are that cut and paste could be done a little better; and it should allow shortcuts like Internet Explorer. I really don’t like bookmarks.

On the plus side of things, it allows Java and Javascript.

Microsoft tried to set the standard for both programming languages, but Sun Microsystems wouldn’t put up with any of that, so Microsoft purposely crippled all future versions of it’s browser – and as a result – Internet Explorer will no longer enable Java or JavaScript. Also, Dynamic HTML is disabled. That was supposed to be one of the next steps, in the evolution of the internet.

Microsoft and it’s monoploy have done more to cripple the internet, than all of the spammers, virus writers, adware / malware writers, software pirates, and hackers combined.

Sandra asks…

FIREFOX…?

I have asked several questions, and many of the replies suggest that I consider FIREFOX. I’m not sure what it is – probably a browser. Is it similar to Netscape and Internet Explorer? What are its good features and its bad features?

admin answers:

Firefox IS a browser, published by Mozilla, that has been competing with Internet Explorer for the past couple years. It’s actually a pretty cool browser that has turned out to nab more of the market than I think most people anticipated.

Good features:
Great pop-up and spyware protection. This is also partly due to the fact that the vast majority of viruses and spyware are written FOR Explorer, which most people are running.
Probably the best feature of Firefox is tabbed browsing, which opens up multiple windows within a single window so that your taskbar doesn’t get crowded with all of the webpages you’re navigating between.
Also, from their website…I think this is pretty cool: “Firefox 1.5 delivers easier navigation for everyone, including those who are visually or motor-impaired. Firefox is the first browser to support DHTML accessibility, which, when enabled by Web authors, allows rich Web applications to be read aloud.”

Bad features:
The only one so far is that since most webpages are meant to be viewed with Explorer, I had limited accessibility to some web applications. For example, when Yahoo! Introduced PhotoMail, I wasn’t able to download the upgraded e-mail application because the service was built for certain versions of Explorer only. But as Firefox gets more popular (they just released an upgrade) I expect this to happen less.

So the people recommending this browser were absolutely correct! I have used it for almost a year now and love it.

I need help with the vnc app on my ipod touch?

I recently downloaded vnc onto my ipod touch and need help using it. It asked for my ip address which i typed in but then it said vnc password and i dont know what that is or how to find it.. Help please!?
thanks, everything worked except now it just wont connect, do i keep the computer off or on?

admin answers:

Http://www.youtube.com/user/RKsipodtouchhelp that is my youtube account. I have two videos on vnc. I dont know if you are using vnc for the dislpay of your ipod touch on your computer screen or the display of your computer screen on your ipod. I have a video on both so you should be okay. If you have any questions please leave me a message ON YOUTUBE. Also if they help i would appreciate it if you would subscribe and spread the word. I hope i helped.

Your computer must still be on and the vnc server needs to be on. If you close the vnc server out and then it says it wont connect you need to go back to configure password and then re enter that password again. PLEASE SUBSCRIBE TO MY VIDEOS.

Carol asks…

How come Vine VNC won’t work with my mac?

I have a power mac g4 with os x 10.3.2 and I downloaded Vine vnc and installed it. When I opened it up though, It said the server stopped running? It also shows something on the sofware about port 5900, I though I forwarded the port correctly but I don’t know? Does enableing UPnP on my router atomatically forward ports that are needed?

admin answers:

Looks like you’re stuck at version 3 at the latest so verify you have the latest version MacOS 10.3 can support.

Http://www.versiontracker.com/dyn/moreinfo/macosx/16699

Enabling uPnP on the router will only help if you’re trying to get onto your machine from the Internet. You still need to open those ports on your Mac. I’m not familiar with the firewall configs on 10.3 but in 10.6 it’s in System Prefs > Security > Firewall.

You can run MacOS 10.5 on a Power Mac G4, or 10.4 as well. It’s something worth considering to make your life a bit simpler.

Joseph asks…

how to connect remote computer via vnc?

i download vnc software to access my friend computer via vnc .i have ip number also, but it cannt connect. pls anybody explain me to how to connect

admin answers:

Traditional way:
1. Make sure the vnc is running on your friend’s pc, and configured correctly (password, access control etc).
2. Make sure the filewall on your friend’s pc is not blocking vnc.
3. Make sure the ip he/she gave to you is correct. He/she may want to use a dynamic DNS service http://dyndns.com to track the ip address change. Nomally ip will change once a month on a dsl link.
4. If your friends pc is behind a NAT router, i.e. His/her pc has private ip address like 10.x.x.x or 192.168.x.x, he/she need to configure portforwarding on the router to forward tcp port 5900 to his/her computer. Note that once he/she does that, the vnc server will be exposed to the whole internet. So better chose a strong password!
5. Make sure you input the right ip (must be a public ip) and right password.

Easier way:
Use Gbridge ( http://gbridge.com ). It is a free software. It has built-in ultraVNC that runs on top of a google based VPN, so it is much safer. It can penetrate NAT automatically. You and your friend both need to install gbridge and invite/accept each other as “friend”. You and your friend would need two google account names to help identify each other (google accounts are free to get anyway). You do not even need to keep track your friend’s machine’s IP address, no port forwarding needed either. Your friend will see you in the gbridge window. He/she can start chat with you and send a DesktopShare invitation to you so you can see (and control, if your friend allow) his/her desktop together with he/she.

If you have multiple computers, Gbridge can do password-base access control as well (don’t need invitation) as long as the computers are login under the same google account.

Gbridge also provides other cool features such like folder sync, file backup, private file share among friends which are fun to explore!

Your Questions About Tight Vnc

Carol asks…

windows tight vnc issue?

I’m using tight VNC to access my desktop from my laptop, and it works fine when I’m on the same network, but when i change networks it stops connecting please help.
what do you mean forward the ports give me instructions

admin answers:

The IP addresses you get when you connect to a router at home are known as RFC1918 addresses and are “private” IP addresses. This means that these addresses are not accessible from hosts on the Internet. Think about it for a second, if your computer’s IP address is 192.168.1.100, there are millions of other computers in the world with that same IP address, because there are millions of people with the same router. How would the Internet be able to handle that? The answer is that it can’t.

Your router has public and a private interfaces. The private interface is usually something like 192.168.1.1 and the public interface gets an IP address from your Internet service provider. You can find out what your public IP address is by going to www.whatismyip.com from a computer that is connected to your router.

In order to connect to your computer from the Internet, you need to use your public IP address, but you have to tell the router what to do with the VNC traffic when it received it from the Internet. That’s where port forwarding comes in, and works like this…you forward TCP port 5900 to your computer’s private IP address (the 192.168.x.x one). Exact instructions are beyond the scope of this answer since you haven’t given us any information at all about what router and ISP you have. However, you should now have enough information to know what to search for to find what you need. Good luck!

David asks…

Tight vnc can’t figure it out please help?

ok my dad and I are in America and my uncle is in India and my dad wants to remote desktop with our computers. So I found tight vnc which is a free software based on realvnc. I got the connection working over here in America between my dads laptop and my computer but when I
tried to connect to my uncles computer it didn’t work. He installed it too and ran the server. He gave me is ip too by going to whatismyip.com. I won’t say the ip address cuz I know it’s not safe but please tell me how to get it working. I know I’m doing something wrong. Thanks

admin answers:

If he is behind a router, then NAT is being used and you would need a VPN connection in order to connect to him.

If that is the case, then I’d recommend using a program called Hamachi to overcome this.

Linda asks…

How can I remote log or VNC via internet to my computer?

My other computer is in Spain (am in the UK), and my brother is having problems using it. I want to remote log or VNC into the computer. I have installed TIght VNC on both computers but when I put either the IP address or the computer name it wont let me access it. Can anyone help me or have a better idea how I can access the computer from the UK? Proper answers please. Cheers

admin answers:

The easiest solution for quick access is Teamviewer – get your brother to download the customer module – he just has to double click it and send you the ID and password via email to connect remotely.

Now, you download the full version which you can run without installation too – you enter the details and you should connect remotely to the otther pc.

Joseph asks…

Can anyone help me get Tight VNC working over a LAN?

I’m trying to set up tightvnc over a local area network, at least for now. I’m fairly tech-savvy, but no matter what I’ve tried, this just won’t work. However, I keep on coming across the error, failed to connect to server (server name).

Both computers are on the same network and can see each other just fine. I’ve typed in the correct IP address. I’ve tried both the internal IP address, as well as the external one with the port 5800.

I’ve configured the VNC ports for port forwarding (5500, 5800, and 5900), but I don’t think that matters for connecting to an internal IP address ( I could be wrong).

Any help? Whatever I try, the exact error message is “Failed to connect to server (192.168.1.4)” I even tried it with the server name instead of the IP address, but same problem.

Thanks in advance.

admin answers:

Try disabling your firewalls temporarily. Disconnect the computers from the internet for the duration if it makes you feel safer. This is most likely a firewall issue and this will confirm it – if it suddenly works you need to revisit your firewall configs.

This is a home network? Many corporate networks disable all but the needed protocols at the router, if it is a home network though you shouldnt have to worry

Jenny asks…

Tight VNC Software?

I would like to set up a server (a Solaris work station) and viewer (Windows on a laptop). Can someone please give me step-by-step instructions to do so? Thanks a lot……

admin answers:

Not much to say. The Solaris server should have VNC running (listening). Once you know the IP address of the Solaris server, run VNC on the Windows Laptop. Be sure to setup a password and you will have to open a port in the firewall if you plan to take control of the server outside the network.

Your Questions About Debian Linux

Carol asks…

Help with open source OS?

I have been looking at different Linux/open source distributions and i have narrowed down my options to either Debian or Open Solaris. Can you give me a comparison of the 2 and what would your choice be for programming/editing/playing around with the OS.

I’ve not had that much experience with Solaris however I can thoroughly recommend Debian as it can be pulled around all over the place and still work. Also it is unlikely that you will get anything more stable than Debian.

I need help building myself a PC?

Well, I think im going to buy the parts individually online probably on newegg. I think im going to put debian or ubuntu on it, definitely a linux. My brother build a computer himself, its amazing and he has better specs than most 700$ computers that you could buy from microsoft. The total cost of his parts were about 360$
So far I understand that im going to need, a case, a hard drive, a mother board, a wi fi card, a graphics card, a CD drive, a power source, and a monitor. Am i missing any parts? does anyone have any good suggestions for the specs that isnt too expensive?

admin answers:

I could advise you on how to proceed,but you haven’t said what you will be using the computer for! Browsing? Gaming? Video editing? Building a system can be great fun,and is very rewarding, but it’s all too easy to make (expensive!) mistakes, even if you think you know what you’re doing! (I know,I’ve made a few!) How about starting off by building a system from old,unwanted/redundant computers before you start splashing out your hard-earned cash. This way you will get all the bits you need to learn on for free,or almost, and you will learn soooo much, and remember,google is your friend. I’ve not had one problem that the Internet community couldn’t help me with. (not quite true,Psychiatric nurses are worth there weight in gold ::)

Michael asks…

apache httpd ?

when i do “top” in my linux, i keep seeing httpd …like every 30 seconds….is that bad?And if yes how i can invisitage it properly? i am on debian with a php/mysql application with heavy traffic.

admin answers:

Apache, by default, is set up for worker processes to exit after handling a limited number of requests. This is designed to not allow memory leaks to get out of hand.

Usually, the main Apache process will reap any of its workers that exit. However, on a heavily-loaded server like you describe, the main process may not have enough time available to it to do this reaping. Unreaped (“zombie”) processes show up as in top. In this case, the processes are normal and are not of concern, unless there are many, many unreaped processes.

However, an alternative possibility is that your worker processes are dying abnormally. This can happen if your web application (or its engine) has a bug which causes the worker process to crash. You should look in your Apache error log to see if there are any serious error messages in it.

The below explains what means. If you aren’t a Unix system administrator, this may not be of interest to you.

Normally, when a process exits (normally or abnormally), it enters a state known as “zombie” (which in top appears as Z). Its process ID stays in the process table until its parent waits on (or “reaps”) it. Under normal circumstances, when the parent process fully expects its child processes to exit, it sets up a signal handler for SIGCHLD so that, when the signal is sent (upon a child process’s exit), the parent process then reaps it at its convenience.

If the parent process has hung for some reason, such as if it’s suspended, or is too busy, or is deadlocked, then child processes that exit will not be reaped (until the parent process resumes again). This can cause serious problems if there are many child processes, occupying slots in the process table that will not be freed.

In that case, one solution (if the parent process is unrecoverable, say), is to kill the parent process. Then, the child processes will be reparented to the init process (process ID 1), which will reap them. (If the init process is stalled, then you have much, much bigger problems than child processes not being reaped. In fact, a crashed init process will usually cause a kernel panic.)

Your Questions About Debian Linux

Jenny asks…

computer operating systems?

how many os’s are there for use in a pc. i know of linux and it’s variations, windows, mac os, and unix. I mean currently used, not such as dos which is no longer a regular use os since windows has taken over it’s functions. note, redhat, fedora, *buntu, debian, etc are all linux based os’s. what i need are the names of independent os’s used on pc’s.

admin answers:

Well, unfortunately you have pretty much covered it for the PC.

The PC started out with DOS, then Windows came along. In the beginning Windows ran on top of DOS and was little more than a fancy front end. Windows has since grown through several major revisions and, in the process, managed to use its monopoly position to not only crush any potential competition from competing operating systems, but managed to “integrate” various features that were once considered applications into their OS or their tightly integrated office suite.

Linux and its variants have survived for the simple reason that one can’t use a monopoly position to apply financial pressure to a product that uses free and open source components as its basis. Unfortunately, the operative word is “survive”. Although there are several pretty darned good Linux distributions, none of them have become slick enough for widespread main stream adoption by your average mom and pop user. Let’s face it, most people just aren’t geeky enough to work through problems like: Is there a Linux driver for my favorite device, and does this mean that I am going to have to download the source and re-build my kernel?

As far as the mac OS goes, up until very recently it was limited to propriatary hardware. Personally, I find it heartwarming that many people are opting for a MAC when they go to replace there home computer. After all, a MAC will surf the web and send email with the best of them, plus it’s hard to beat for home video editing and other creative endevors.

David asks…

How can I backup my server?

I have a 1&1 Linux server with Debian on it, and I want to backup all or at least most of its contents to my Windows PC at home. Is there any software that will do the process for me? (Preferably something I could just install on my PC)….hate command line stuff. lol

I’ve seen server software for Linux and server software for Windows and because I would be archiving cross-platform, I’m a little confused. Thanks!
I have no physical access to the server….it is in Kansas and I am in Texas.

So manually using FTP is the only way to go? No program that will automate the process?
I said I’m using a Linux server…….not Windows.

admin answers:

Get a usb backup drive, backup to the drive. If the data is not worth the price of a backup drive to you, I don’t know what to tell you. You could install an ftp server and get data that way, but its going to be long and frustrating.
I don’t really know of an automated way.
Basically install filezilla server on your home computer, and filezilla client on your linux box if you have graphical access. The problem with normal FTP is that it cannot be done recursively, so you need something like filezilla that will let you upload a whole filesystem at once by dragging it. Really thought about this, but can’t think of anything else.

You also could gzip the whole filesystem (make sure you you have space to do this) and just send over the one file with FTP if you do not have graphical access to install filezilla client. (you could then just use command line ftp for to send your one file). A small script could be written to automate this from time to time, make sure you don’t fill up the filesystem though. But then to automate, you’d need a static IP or dyndns at home….

How to fix that error in c++?

I am trying to connect to mysql server with c++ but I got a problem.
I am trying to compile with g++ and run on Linux Debian.
When compiling with this command: g++ test.cpp -I/usr/include/mysql -L/usr/lib/mysql -lmysqlclient_r -o test I get this:
/usr/lib/gcc/x86_64-linux-gnu/4.3.2/../../../../lib/crt1.o: In function `_start’:
(.text+0×20): undefined reference to `main’
collect2: ld returned 1 exit status

And code looks like this:

#include
#include

int main(){

MYSQL mysql;
MYSQL_ROW row;
MYSQL_RES *result;

unsigned int num_fields;
unsigned int i;

mysql_init(&mysql);

if (!mysql_real_connect(&mysql,”localhost”,”root”,”not telling you this”,”test”,0,NULL,0))
{
fprintf(stderr, “Failed to connect to database: Error: %sn”,
mysql_error(&mysql));
}
else {
if(mysql_query(&mysql, “SELECT * FROM test”));
//here goes the error message :o )
else {
result = mysql_store_result(&mysql);
num_fields = mysql_num_fields(result);
while ((row = mysql_fetch_row(result)))
{
unsigned long *lengths;
lengths = mysql_fetch_lengths(result);
for(i = 0; i < num_fields; i++)
{
printf("[%.*s] t", (int) lengths[i], row[i] ? row[i] : "NULL");
}
printf("n");
}
}
}

return 0;

}

admin answers:

Try using this command line instead:
g++ -o test -lz `/usr/local/mysql/bin/mysql_config –include –libmysqld-libs` test.cpp

Or something similar, depending upon where your MySQL libraries are.

Thomas asks…

Has anyone used eLive?

The Linux distro. It’s Debian-based and uses the enlightenment desktop
And is it any good?

admin answers:

I use enlightenment as my primary desktop. I have been using it for the past three months or may be more. But I am using it on a Debian system.

As such, enlightenment is good if you are open to new kinds of ideas in window managers. I use it because it runs great on my 128MB RAM machine. The machine shows its lack of speed only when I build a massive project.

So, if you are looking for downloading it, I suggest you install the packages that ‘elive’ provides, from your Debian or Ubuntu repos and have a test run of sorts. That wil save your time and bandwidth ;)

Your Questions About Perfect Mail Server

Lizzie asks…

I can’t receive emails?

I use Windows Mail (Don’t tell me to swith mail programs, because i don’t want to) and everytime i click “send and receive i get the same error

The connection to the server has failed. Account: ‘mail.bigpond.com’, Server: ‘mail.bigpond.com’, Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

Why does this happen? I have a perfect internet connection and it still doesn’t receive? Why?

admin answers:

First check that if you are not behind any protected network, then check that the secure protocol you are using (port) is correct and the check that username and password are correct.

One way to check if you can connect remotely to a port is by making the telnet host port (where you replace host with the address and port with the port number used).

Hope this help.

please give me the solution to help me out of these problem.
I will give u best mark.
thanks.

admin answers:

#2 may be because your web browser is not equipped to open that page, (unlikely tough) try a different web browser, try to open it with, Internet Explorer, Mozilla Firefox, Opera, if none of these can open it ,its probably not a browser problem
If one of these can open it than its a browser problem and you need to go that webpage with an alternate browser.

#1 to download you may need adminstrative access to the computer, limited accounts cant always download

also if you have some computer cleanup software like CCleaner, they sometime block you from opening email attachments( I experienced this) but you would still be able to download at this point

#3 all I can guess on this is that there is a problem with the page

William asks…

Do you want more neopoints on Neopets?

I found a glitch in the system: Read on, NP lovers, read on!

Ok…You may not want to do this because it involves taking np from someone elses account. But maybe theres somebody who was being mean to yoo on the boards, and this is the perfect way for you to get back at them!

Is it possible to
take over someone’s account without having to go to a university
course on hacking and security or using big and sophisticated
programs? Yes.

People have been trying to find fool-proof ways to find out a users
password now and this document will teach you the easiest way to do
so – all you need is an active e-mail account, aswell as an account
on neopets. Before you read on, make sure you have those two things.
Neopets is run by a few people known as `Admins’ (short for
Administrators). These admins have access to all parts of neopets
and have full control over everything, they even have their own
neopets accounts that let them interact with the server. They can do
anything from …
from adding new games and pages, to resetting a users
password. Now, with the power of being an admin, you could take
anyone’s account you wanted, so all you have to do is fool the
neopets external server into thinking that you are an admin. To do
this read below.

Open up a new e-mail message, and in the `To:’ type this address
theneopetsteam@theneopetsteam.com ( i think that’s it) this is because way back when neopets was created,
the admin server was installed on a different adress while the
actual neopets site, was placed on a different one, so that if the
site went down, the admin server would still run.

In the `Subject:’ line, type `c134 nlostpass’ – c134 just tells the
server that it needs to forward this e-mail to the password
database, adminpassrecovery is the command that tells the password
database to return a password to the sender’s e-mail address. (if
you don’t understand any of that, don’t worry, its not important)
In the body of the …
message, type this-
NOTE: The parts in are is the place you need to enter in some
information, like your username, and the account’s username.

-c134
-~!adminpassrecovery
-!srvcode-77342 53252 98134 342
-!STARTsub
-~adminaccess
-!-usnm-
-!-acs-
-!pn-
-~returnpass
-!-usnm-
-~c134!ENDsub
For an example, say my neopets username is `timmyotool’, my password
was `123456′ and my PIN number was ’4576′ and I wanted to get the password for the
account `richerthanme’ your e-mail would look like this-

-c134
-~!nlostpass
-!srvcode-77342 53252 98134 342
-!STARTsub
-~adminaccess
-!-usnm-
-!-acs-
-!-
-~returnpass
-!-usnm-
-~c134!ENDsub

Once all the information is typed correctly send the e-mail, and
allow at least 24 hours for a response….
Because the server is old and outdated, it is tricked quite easily
by the set of command in your e-mail message, it now thinks that you
are a neopets admin and it will give you the information you
requested without question. Now you can have access to all those
people that have millions of neopoints and rare items, ad steal them
from right under their nose.

P.S. If you don’t have a PIN # just say none…., oh and do all of your accounts because that way you get more $$

admin answers:

Okay this sounds useful…

Your Questions About Debian Linux

Donna asks…

Job qualifications for data entry/data processing?

I want to get a job in data entry/data processing.
Right now i’m 15 so around February of next year, I’ll be applying in different offices.
Are there certifications and/or special skills I need/should have in order to help me get a job?

I already know Windows XP, Vista, Debian GNU/Linux based os’s, http, the Microsoft Office suite (including Access and Visio).
I also have skills in Photoshop and After effects. Those might be useless though.
My WPM is 49 with high accuracy.
I’m fluent in both English and Spanish.
(this is sounding like a resume)

So again, are there any other special skills/certifications I should know/have?

admin answers:

Just got to be a fast typer. There are 2 types of fast typers. One who can type really fast, writing words. Then there are numbers! They are looking for somebody who can type fast with numbers. Your other qualifications probably don’t matter as much. It might actually scare people because you sound like u would leave the job because you’re too smart for it. I think you’re qualified, but the thing is…there are so many people applying. It’s a matter of luck!

Susan asks…

should the government stop using social networking websites?

I think all of the white house’s youtube, myspaces and other pages should be shutdown, along with all the others… they are a waste of time and completely pointless. I’m 21 and I don’t even use facebook or twitter. I tell ya what, they aren’t reaching me with their lame twitters or tweeties or whatever they’re called… and it’s not like I’m not tech savvy… I’m using Debian GNU/Linux and I drown myself in technology daily…

since when was the last time you went to the nearest government building and give all the people working there a thumbs-up while you walked around watering their fake farms and commenting on their clothes, asking them what they’re doing tonight or whatever… really… have you ever walked past a senator or governor and said “omg he likes me!!! <3" followed up by what youre eating five minutes later?

admin answers:

Government employees are probably the biggest waste of tax payer money. We need some of them, but there is too much red tape and way too much inefficiency.

Helen asks…

How many gbs or gigs do top OS take?

How many gigs does it take for:
Vista
Windows XP
Ubuntu
Fedora
Debian
Mint

Also,
I heard ubuntu 7.04 was 3 gigs or somethings, and that vista was only 2. I thought linux was always smaller than anything Microsoft. Can anyone verify that as well? I could be wrong.

admin answers:

All 32 bit os’s are limited at about 3,25 GB. The 64 bit os’s are only limited by the motherboard.

Laura asks…

Is this really possible?

I saw a video and a guy was dumping EVERYTHING off of a iPhone. Even the Kernel and BIOS! I dont know how he did it, but then he ported D@mn Small Linux onto it off of a Windows Vista computer. It ran Open Office and all this stuff. IT WAS RUNNING LINUX! Really! IT WAS AMAZING! It wasnt a application or anything it was a real computer running real linux! Somehow, in this porting process, he created something in D@mn Small Linux which allowed him to use the bottom port on the iPhone, through a home-made converter, as a USB port! he then hooked the iPhone up to a Linux Laptop (Debian) and the thing popped up as External Hard Drive. He used it like a real computer. He put a open office document on it and edited it! The video was like an hour long. I watched it in parts for a week. If I knew how this guy did it, I would try it. I dont know if it could still be used as a phone or not? I looked for the video for an hour but it was on a Linux website. It couldnt find it though!

admin answers:

Yes its on google but its hard

Clear some questions on Xbox360?

Ok everybody I know that we can install Ubuntu or Debian or any linux OS on xbox 360 so I changed my mind and I want to go for the Xbox 360 ELITE. Also on this site: “http://news.teamxbox.com/xbox/12316/Connect-a-Mouse-and-Keyboard-to-Your-Xbox-360/” I found that we can connect a keyboard ‘n’ mouse to the console.
So I have 1 question in mind that will I be able to browse the internet like I do now on PC once installed ubuntu on the console?

admin answers:

No you cant use the 360 to surf the net. Linux on the 360 is made possible for a dev stand point.
