serial console not displaying login

[raggmopp]

Hi all:

Got a headless SUN E420R with 2.8 installed.
Have a Lantronix device hooked up to the ttya port.
Doing a telnet to the device/port I get the telnet response saying it is connected but I never get the login prompt back.

We have 10 other same SUN servers hooked up in similar fashion yet they provide login prompt fine. I have been through admintool but I see no differences between them.

Many thanks

Have you tried swapping over the cable and adapter from a system that works to the system that does not?

Have you looked at the setup on the Hardware its self?
I had a problem like that on a d-terminal. It was in the setup on the terminal not software.

I had a similar problem, I could boot the machine from the ok prompt watch it come up but never get a login prompt.

It turned out to be a script in /etc/rc3.d that was stuck waiting for an input. Sorted the script and sorted the login problem.

if this worked before check this:
sometimes the ttymon gets stuck...

if you can connect to the host via ethernet just kill the ttymon, it's restarted by init Process automatically, after that you should get a login prompt on the console
