[comp.sys.apollo] Problem with telnet hanging at login

thallem@guille.ece.orst.edu (Michael G. Lohmeyer) (04/13/90)

I have been upgrading to SR10.1 over the last month and have encountered
a problem that I can't seem to solve.  I can't get telnet logins into an
SR10.1 node to work.  I hope that this is something that I have done
wrong, but I fear that it is a software bug.  If so, what can I do
about it?  I hope that someone can help me.  The specifics follow.

We were an SR9.7 network a month ago.  At that time, I had one machine
running SR10.1.  Telnet to that machine worked fine then.  Then I upgraded
the rest of the machines to SR10.1.  The registry was completely converted
over to my orginal SR10.1 node before doing so and it is now my only 
registry server for 7 machines.

After the upgrade to the other machines, when ever I telnet to a machine
(including the original SR10.1 node), it always works the first time
after I reboot the machine, but never after that (or at least as far
as I can tell, it only works once, the first time I try after rebooting).
When I telnet in, I get the machine operating system banner, but 
the login message never comes up.  It hangs at that point and I have
to use ^] to get back to the calling machine.

After doing this, I do a ps on the machine that I just tried to telnet to 
and find out that there is a telnetd process still running.  In fact,
there will be one telnetd for each telnet attempt tried, even if the
telnet worked.

I have check the /etc/services and /etc/inetd.conf files and they seem
ok.  The following lines are from those files:

/etc/services:
telnet		23/tcp

/etc/inetd.conf:
telnet	stream	tcp	nowait	root	/usr/etc/telnetd	telnetd
shell	stream	tcp	nowait	root	/usr/etc/rshd	rshd
login	stream	tcp	nowait	root	/usr/etc/rlogind	rlogind
exec	stream	tcp	nowait	root	/etc/rexecd	rexecd

A possible connection is that sometimes rlogin (or rsh) will, when
asking for password, hang when you try and type the password.  I have
not found a patteren here yet.

Does anyone have suggestions as to what might be the problem?  If I get
several personal messages, I will post a summary to the net.

Thanks

Mike
