telnetd: all network ports in use

[Brian Schwarz]

After rebooting my Linux box for the first time in multiple weeks, I get the
following error when I try to telnet in:

telnetd: all network ports in use

Everything else seems to be working (http, pop3, smtp), so I'm pretty
confident that connectivity and IP address issues are taken care of.
I did some searches, but the only things that I came up with was to
check to see that /dev/ptys0 throught /dev/ptys9 exist. They do.

I've confirmed that there are no other users connected to the machine.

Any ideas about how I fix this? I need telnet access for a variety of
reasons.

Any help (or ideas about where to look next) are appreciated.

Thanks,

Brian

Found the problem. There was a typo in my /etc/fstab file that was
preventing /proc and /dev/pts from mounting properly. I'm surprised I
didn't run into this problem before - I made the changes to the /etc/fstab
file a few weeks ago. Thinking back, however, I didn't rerun the entire
fstab file with /bin/mount -a, I just remounted the drives using some KDE
tool.

Oh well, live and learn.

What version of Kernel and what distro.. If it is a 2.2.x
/dev/pty* are no longer used... nowadays we mount a virtual FS
(much like proc) under /dev/pts/ , check to see if the correct
entried are in /etc/fstab to mount it
Like this:
none /dev/pts devpts
mode=0622 0 0
