I'm having a problem with the login program hanging when getty
passes control to it.
To eliminate any extraneous device influences, I've looped sio0 to
sio1 using a null modem cable. If I use tip on both serial ports
simultaneously, everything communicates fine. When I enable getty
on one of the ports and tip to it from the other port, getty accepts
a login name, forks login, which gets stuck. Eventually login
times out and getty restarts. Here's what it looks like:
========================================================================
Running tip from cuaa0:
root@infoserver.ee.siue.edu# tip slink
connected
FreeBSD (infoserver.ee.siue.edu) (ttyd1)
login: bnoble
Password:Login timed out after 300 seconds
FreeBSD (infoserver.ee.siue.edu) (ttyd1)
login:
========================================================================
What's happening on ttyd1:
root@infoserver.ee.siue.edu# ps auxwtd1
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
root 23088 0.0 1.1 156 520 d1 Is+ 10:22AM 0:00.02 /usr/libexec/getty std.38400 ttyd1
root@infoserver.ee.siue.edu# !p
ps auxwtd1
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
root 23088 0.1 1.4 220 668 d1 S<s+ 10:22AM 0:00.06 login -p bnoble
root@infoserver.ee.siue.edu# !p
ps auxwtd1
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
root 23088 0.0 1.4 220 668 d1 I<s+ 10:22AM 0:00.06 login -p bnoble
I've tested this on a 686 running 2.1.6 and 2.2 and also on a 586
running 2.1.5. Both system do exactly the samething. Does anyone
have any insight into this problem?
Thanks,
