How to configure TELNET in RH 7.3?

Hi all,

can anybody give me the steps to configure Telnet in RH 7.3?

What is the rpm?

What are the Key Configuration Files? What are the settings?

Plz try to put it in detail.

Thank you.

If you did a standard install, I think that it should already be there. Have you run rpm -qa | grep telnet to see if it shows anything installed? If it does show telnet installed, try running lokkit to configure the firewall to allow port 22 for telnet.

First, telnet uses port 23, not 22.

Second, you SHOULD NOT USE TELNET, PERIOD. The telnet login protocol is inherintly insecure. It transmits all information in plain text, including username and password. This means it takes a trivial amount of effort to obtain all passwords sent over telnet sessions.

Use OpenSSH as a replacement for telnet. SSH encrypts all traffic, including authentication information. SSH uses port 22/tcp. It is also included by default in nearly all Linux distributions.

Hi friend,

thanks for that. I never knew the lokkit utility.

I could resolve my problem with two of the RH boxes(8.0,7.3).

Is there any utility in United Linux or SuSE like that for firewall configuration? I didn't find the lokit utility there.

Hi Cort,

thanks for the information.

Can I contact you through personal mail whenever I have any doubt regarding security?

Sorry about misleading you with the port, I always get that confused...

I can't promise that I'll answer all your questions, or answer quickly, but I do try to help newbies when I have the time. I am employed full-time in the InfoSec industry, so some times it can get very busy. I'll do my best.

PS, when in doubt a simple

grep -i <service> /etc/services

or

grep <port number> /etc/services

should reveal the answer to port number riddles.
