Question telnet problems


I having problems using telnet in ubuntu. I never used it before and am not sure of the procedure or the commands involved, could someone help me? I use Ubuntu 9.04 and I have Cox ISP and they use DHCP could it be that they don't allow telnet capabilities? What can I do?

Have you typed
Code:
man telnet
in a terminal? There's lots of useful information there. Try to learn to google a little. Learns a lot of information out there. Here's a sample:

Have fun,

As stated 'Google' and LQ are your friend. You can do searches here on LQ.

I suggest that you look at 'Rute Tutorial & Exposition' and 'Linux Newbie Admin Guide' to aid you in understanding GNU/Linux.

The above links and others available from 'Slackware-Links'. More than just SlackwareŽ links!

BTW, the next two links will aid you;

Biggest question is what your trying to achieve. Do you want to connect from Ubuntu to another machine or the other way around?

Telnet is very insecure in this big bad world as it's not encrypted so everybody can see usernames, passwords etc. If the other side supports it, use SSH.

Telnet is still very useful for testing purposes (e.g. check if you can connect to a server on a specific port).

I agree with Wim about the security. You type
Code:
open {hostname}
at the telnet> prompt. I think that
Code:
help
will also give you a list of possible commands.
