RE: PPC login puzzle

Seems to me thing you can do is find out why the telnet session is being =
rejected.  Have you done an ethernet capture?=20

Do you have any firewalling setup?  In that case you need to make sure =
your rules are setup properly.  The ethernet capture should give you a =
clue.=20

Are you sure the telnetd can be found on your system that doesn't work?  =
What do the logs tell you on the machine that doesn't work?  I think =
xinetd kicks out a log file, what does that tell you?

Have you tried on the 8541,  login to the terminal and then telnet to =
localhost?  If you can do that, then I'd say it's a firewalling problem, =
if not, then it's a telnetd type of problem. =20


Hope that helps.

It is interesting that 'telnet localhost' fails in a similar way as =
telnet across the network, and I appreciate your kind hints, especially =
about the log file and /var/log/syslog helps a bit on this problem.
=20
When trying to telnet accross the network, syslog says
=20
in.telnetd[]: connect from x.x.x.x
=20
But entering root doesnt work and the host then says:
sff1 login: root
Login incorrect
=20
There are no further errors on the 8541. When trying to 'telnet =
localhost', syslog says
=20
in.telnetd[]: connect from 127.0.0.1
=20
But neither completes the login, so although there is a clue here, the =
logical path to conclusion is still escaping me a little bit.
=20
I can see that both targets have the same /etc/xinted.d/telnet file and =
it contains:
=20
service telnet
{
 flags  =3D REUSE
 socket_type =3D stream       =20
 protocol =3D tcp
 wait  =3D no
 user  =3D root
 server  =3D /usr/sbin/in.telnetd
 server_args =3D -h
 log_on_failure +=3D USERID
}
=20
which I think is reasonable in this situation. So, this begs the =
question of what other things still bear on this type of problem. Again, =
I appreciate your taking the time to help me understand a bit more of =
how this fits together.
