mgetty problem

Hi Admins,

FC4 on HP Proliant

I had a problem today where users couldn't login to the telnet
application they use. In the end a reboot solved it. I noticed that
there were a lot of errors in the messages file:

Jul 29 04:00:07 mgetty[7424]: init chat failed, exiting...:
Interrupted system call
Jul 29 04:00:07 mgetty[7424]: failed in mg_init_data, dev=ttyS0,
pid=7424
Jul 29 04:00:52 mgetty[7472]: init chat failed, exiting...:
Interrupted system call
Jul 29 04:00:52 mgetty[7472]: failed in mg_init_data, dev=ttyS0,
pid=7472
Jul 29 04:01:38 mgetty[7533]: init chat failed, exiting...:
Interrupted system call
Jul 29 04:01:38 mgetty[7533]: failed in mg_init_data, dev=ttyS0,
pid=7533

and in mgetty.log.ttyS0:

07/31 11:14:29 yS0 timeout in chat script, waiting for `OK'
07/31 11:14:29 yS0 init chat timed out, trying force-init-chat
07/31 11:14:53 yS0 timeout in chat script, waiting for `OK'
07/31 11:14:53 yS0 init chat failed, exiting...: Interrupted system
call

In the past ttyS0 was used (with a modem) as a dial-in terminal but
it hasn't been used in over a year. From my searches I suspect I need
to disable this now.

Will commenting out the lines in/etc/mgetty+sendfax/mgetty.config do
it. Or am I barking up the wrong tree?

port ttyS0
debug 4
data-only y

Any thought appreciated? Thanx,
Dp.

First up a warning. I'm going to suggest you edit /etc/inittab manually
which if done
incorrectly can cause serious system failure. You may even have a gui tool
in kde/gnome etc that would be safer to use but i dont known the
available tools.

Most likely you need to turn off the respawn of the mgetty process in
/etc/inittab.

Check /etc/inittab for a line that looks something like:

ttyS0:2345:respawn:/sbin/mgetty dev=ttyS0 baud=19200

Yours will be different as i haven't run mgetty for years but it will
reference mgetty (not mingetty, getty, agetty or uugetty).
You need to change the "respawn" field in the line to be "off" and then
tell init to re-read inittab with "telinit q" as root.

Feel free to post your /etc/inittab for further guidance before editting it.

Found it. Here is the line I added yeas ago:

# Added by DP for modem use
# respawn off by DP on 31-07-07
S3:345:off:/sbin/mgetty -x3 ttyS0

Should I HUP init now for the change to take effect? Thanx,
Dp.

# init q
