Re: telnet
Set that user's shell to something that doesn't allow logins... So in /etc/passwd change that users shell (the last attribute) to something like /bin/false
Cheers,
Rob

Re: telnet
If this is the case and you want to allow other users access telnet service, then you could use ACL (Access Control List) on the telnet executable file.

Re: telnet
"ls -l /usr/bin/telnet" will list the owner (root), group (root) and the permissions of the file. You should change the group to your special group name (e.g. admins) and adjust the permissions so that only new group and root have permission to execute the telnet binary. The commands are (you must have root privileges):
Change the group:
# chgrp admins /usr/bin/telnet
Remove execute permissions from others, add to group:
# chown o-x,g+x /usr/bin/telnet
