unable to telnet

[Peter Gillis]

Telnet entry in /etc/inetd.conf looks like this on my system (11.11):

telnet stream tcp nowait root /usr/lbin/telnetd telnetd -b /etc/issue
-TCP_DELAY

When a login occurs you should see a telnetd running for that session like:

ps -ef |grep telnetd
root 4692 740 0 16:54:00 pts/tk 0:00 telnetd -b /etc/issue -TCP_DELAY

The inetd.conf entry is basically the startup command for the telnet session. You may like to add the params above to yours.

Did u tried with any other user name, other than root and d46adm. Just to confirm, weather this problem is related to this particular user. And try to login from any other server os PC to verify the host access.

Don't forget to post the results here.

Hello Sushil,

hi sreekanthtm,

yes I have tried this for other user(s) - this problem is particular only for this user and only for telneting using its account.

This might be a little off the wall, but has the user been locked out of the system due to multiple login failures now? use
/usr/lbin/getprpw d46adm
on the box which is not allowing telnet to check on this. Everyone else has mentioned all of the other checks, but is this account using a '@' or a '#' in the password? If so, escape them with a backslash when typing them in or they will cause problems.

Tom, you hit the point!!!

Yes, the password has @ within itself and once escaping it with \ it works!

Now, what to define in .profile to escape it?

To the best of my limit knowledge, you cannot. Authentication is handled before /etc/profile or .profile is executed, so it'a a matter of the system looking for these characters. You can search the forums for a more detailed answer, since this question has been discussed a number of times previously. From my 11i v1 system's man passwd pages:

Avoid password characters which have special meaning to the tty
driver, such as # (erase) and @ (kill). You may not be able to login
with these characters.

This may have been changed since 11iv1, but I'm stuck these days on the older release.

solution; avoid escape characters within passwords
