Hi,

1) xinetd is active:

root@foo# ps -edf | grep xinetd
gives you a line like:
root 345 1 0 Mar 15 ? 00:00:00 xinetd -stayalive ... etc.

2) check for a file named:
/etc/xinetd.d/telnet

3) edit this file.

4) The file look like:

service telnet
{
type = INTERNAL
id = echo-stream
socket_type = stream
...etc.
disable = yes
}

5) change the disable = yes to a disable = no

6) type :

# /etc/init.d/xinetd restart

and this should do.

Hope it helps.

Regards,
Thierry BAILLON

I have a question to the experts. I have telnet enabled and the firewall opened up. Now I get the login screen when I try to telnet from my laptop to the Linux box. But if I enter root and its password, it is not accepted from the telnet screen. The same password is valid on the linux box itself.
What is the secret of this?
Can somebody help me with this?

Most modern Linux distributions deny the ability for the 'root' user to sign in over a network connection, requiring you to sign in as a non-priveledged user, then using 'su' to get priviledged access.

If you really want to, you can change this behaviour (look at /etc/pam.d/telnet, and the 'securetty' line), but I'd highly suggest leaving it as it is.

samuel,

i have answered ur question in ur post.

and to the OP, please use ssh instead of telnet if u are on a public lan or if ur data security is important.
