root user can login through telnet.

did you get any error while connecting?

check in /etc/inetd.conf file for telnet configuration line is uncommented or not.

then run command

#inetd -c

then try to login through telnet.

vi /etc/inetd.conf.

If you unable to telnet to the server

# cat /etc/inetd.conf | grep telnet

Uncomment out the entry

# inetd -c

Then try to telnet

Check for /etc/securetty file
If it contains root, you wont be able to telnet
Remove that entry

Also check
See /etc/default/security - http://docs.hp.com/en/B9106-90011/security.4.html

NOLOGIN
This parameter controls whether non-root login can be disabled by the /etc/nologin file.

# inetd -c will reread the configruation file /etc/inetd.conf

So any changed in inetd.conf will come into effect if you run the above command

It will not affect the server

Hi,
use SAM to manage telnet users, there are even option that you can restrict with IP address and hostname.
You can manage as per your requirement.
If you want allow fews and Restrict to Others its easly manage throw SAM gui option.

#SAM

Thanks a lot.

I have done.

so "# inetd -c " is like restarting inetd serveice.

To restart, can we use below command.
Ex: /sbin/init.d/inetd restart

inetd (1m)
inetd recognizes the following options. These options can be used only by a superuser.

-c Reconfigure the Internet daemon; in other words, force the current inetd to reread /etc/inetd.conf. This option sends the signal SIGHUP to the Internet daemon that is currently running. Any configuration errors that occur during the reconfiguration are logged to the syslogd daemon facility.
