SubjectUnixPTY: running problems?
Hi kernel-programmers!

I'm now using Linux for about one and a half years. Up to now, I was always
able to solve my problems on my own, but with this problem, I currently have, I
can not cope with.
I'm using the experimental version of the kernel [currently it is 2.1.125].
Some time before I used 2.1.110 (around this kernel). In this there was no
Unix98 support. When I updated to 2.1.125 I enabled the new Unix98-PTY-support
without really knowing what it means. To my shame I must confess that I didn't
read the manuals carefully enough so that I could understand what I'm enabling
there. Well - obviously I enabled it, but I didn't update my libraries etc.
The thing went as it must go: Almost no connection was possible via the
network. Not realizing this problem (I did not often use the TCP/IP), I worked
on and on, but some time later I reread the Documentation/Changes file and
there suddently I realized what's going on. Not wanting to update my libraries
I recompiled my kernel disabled devpts and unix98. But this had not had the
wished result: Still any telnet session leads to an "Connection refused" with
the error message "telnetd: All network ports in use". lpd and some other
programs are having problems, too, mentioning the same error messages.
Reading the documentation again, I found out that this problem was already
discussed. So I enabled Unix98 again, started devpts and doing everything that
is descibed in the Documentation/Changes. But this did not have any success
either.
So I dediced some time to the update of my libraries, too. There I experienced
another problems so that I was not able to update the library to glibc6.

So far I tried it on my own. But now, it seems to me that I'm not able to get
my Linux server running again. But there's a funny aspect, too: in my near
there's another Linux server running 2.1.125 too without Unix98. There is no
problem at all! Everything works good and telnet is running fine.

As I do not need the huge amount of 256 clients (on rush hours I have 2 or 3
clients logged in that machine), it would be the best that the old system of
pty's would run again.

Did anybody have this or a related problem, too? Any suggestions/hints?

If my mail is offtopic, can anyone tell me a mailinglist where this issue is
related?

Thanks for your help!
