telnetd: All network ports in use!

From: Dmytro Bablinyuk <hidden>
Date: 2003-07-10 21:33:11

Finally we got u-boot with linux working, but I am experiencing problem with telnetd: "telnetd: All network ports in use!"
I've seen around quite a few reports about the same problem but no one solution really works.
Below I attached some info about my system in hope that somebody may be come across this problem.
Thank you in advance for any help.

I have sorted out this exact problem 2 weeks or so ago.  For me the problem was that the device node telnet was trying to obtain did not exist on my filesystem.  Look in /dev for device nodes ttyp* this is what they look like in my file system:
crw-------    1 root     root       3,   0 May  7  2002 ttyp0

I have added 16 of them.

Rod Boyce
