Hi,
how do I setup/enabled telnet access only for particular directory, when any user log-in on to my server, he gets something like below pattern on to remote server, and only login to specified directory, also he need to run few bash commands.

[ravi@mydomain00 ~]$ telnet mydomain.com
Trying 127.0.0.1...
Connected to mydomain.com (127.0.0.1).
Escape character is '^]'.
Password:
mydomain00> Sun Oct 10 22:37:04 PDT [telnet_0:info]: root logged in from host: 10.1.0.5

mydomain00> pwd
"/var/www/pwd"

mydomain00>

Hi -

You'd be much better off using sshd instead of telnetd:

1. "telnet isn't secure and you should't really be using it"
<= You've probably heard this before...
... and it *isn't* untrue!

2. "ssh" comes with lots of options to restrict users, restrict IPs,
assign logins to alternate shells (e.g. Restricted Bash "rbash" instead of "bash") and confine them to "chroot" directories.

For example:

3. Besides, "ssh" is more secure and better supported in modern OS's.

IMHO ..
