I want to know how can i enable others to connect to my pc using the telnet. I am using mandrake 9.1

I would suggest avoiding telnet. It is very insecure - any transmissions that occur are not encrypted, including things like passwords, so anyone who might be eavesdropping could find out your users' passwords and whatnot.

The best alternative is Secure Shell (ssh, or open-ssh). Mandrake may have installed it for you. If you installed any package called "sshd", then you already have it, and it's probably already running. Check out the OpenSSH homepage for documentation and stuff.

If you really want to use telnet, see if you can find "telnetd" on your installation discs, or if you have already installed it.

Good luck!

You need to install the telnet-server RPM package.

To enable telnet, you will need to edit /etc/xinetd.d/telnet
Change the disable line from Yes to No.
Then you will need to restart the xinetd service.

It's amazing how different two GNU/Linux distributions can be! On Slackware, telnetd is installed with the tcpip package. You would just uncomment the line for telnet in /etc/inetd.conf and send the HUP signal to inetd to restart it.

Can anyone tell me by what command the users will be able to export the graphics from my pc, when they are working on the telnet console.

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.

That would include asking the same question in 2 different threads

Thanks

Cool

Well, if your users are using ssh, and assuming they are running X servers on their own computers (which they are, if they are using Linux) it's really easy. All they have to do is:

ssh -X username@yourhostname

The "-X" tells ssh to export all the graphics. Pretty cool, eh?

With telnet, it's a little harder; users may manually have to set the DISPLAY environment variable after they log in, like this:

DISPLAY=user's.host.computer:0
export DISPLAY

Check out the Remote X Apps HOWTO for more info.

WHAT IF THE client is using windows. .... then what do i ll have to do. Please tell me from both sides.

Now when i connect throught the client using telnet and use the


export DISPLAY=10.1.5.20:0


server IP = 10.1.5.6
clienr IP = 10.1.5.20


i still get the error message that X system is unable to export the graphics and check the xhost.

can someone help me out with this.

Please read the HOWTO that I gave you earlier. It answers most of the questions you are asking. We are more willing help those who are willing to help themselves

i need to agree with others, do not use TELNET but use SSH, you can use putty, it is ssh client for windows.

In the ssh windows enter the ip address of your server and select your the SSH port 22, then input the user name and the password.

Then follow the instructions that given by wapcaplet.

use a simple script...like this...

/sbin/iptables -A INPUT -p tcp -s 0/0 -d x.x.x.x/24 --dport 23 -j ACCEPT
/sbin/iptables -A FORWARD -p tcp -s 0/0 -d x.x.x.x/24 --dport 23 -j ACCEPT

here x.x.x.x is the IP address of the host/network from the network you want to access by telnet
write this in a script with a name say 'enable-telnet' and run in with ./enable-telnet
if permission related complexity arise, give proper permission to run it.
