I don't think your problem is in in.telnetd. We had the same problem
here. It turned out to be /bin/login hanging. If you see a /bin/login -h
hostname -p hanging around the same ptys that the telnetd is attached to,
you have the problem I am talking about.
The cause is that inetd was manually restarted from a shell, and thus
inherited the environment of it's parent process. It's this environment
that causes things to wedge, because the -p flag to login tells it to
preserve the environment, and the environment that it inherits from inetd
screws it up. Rebooting the system creates a fresh inetd, minus the
contaminating environment. SUN knows about this, and it's fixed in 4.1,
due out soon. I forget the bug #, but if you tell this to your system
support people, they can probably get it from SUN.
Thanks,
Milo
