By default, and for security reasons, all inet services are shut off.
You can turn them on by editing the /etc/inetd.conf file. Find the
service you want to turn on, and remove the # at the beginning of that
line.

Then run:

/etc/rc.d/init.d/inet restart

You'll be all set.

Be very careful to make sure that there are no leading spaces before the first word in the line. For instance, the line:

telnet stream tcp....
will work, but the line

 telnet stream tcp...

will not. That was my problem, and it was tough to figure out the problem!

I used both method mentioned above, but I still can't telnet back to my LinuxPPC.
The error message is:
telnetd: All network ports in use.

??
So, what should I do now?

And thanks for any help...

Check your /etc/fstab file it needs to have the following line for
ports/ptys to work correctly:

none     /dev/pts     devpts   mode=0622 0 0

If the above line is missing or corrupted, then this could explain what
you're seeing.

Above the pts line is typically the line for proc:

none     /proc      proc       defaults 0 0

I've seen a situation where the pts and proc line somehow got combined
into one line.
