Description hiller 1999-06-27 09:55:02 UTC
When I start ppp with a setup that works with 5.2, I got the
following error:
Jun 27 11:48:35 lonestar mserver[775]: Executing:
Jun 27 11:48:36 lonestar kernel: CSLIP: code copyright 1989

The chat script is an expect script.
What is wrong here ?

The options are:
asyncmap 0

The dial script is:


exec /usr/sbin/pppd $device $speed file
/etc/ppp/tuhh.options connect /etc/ppp/tuhh.expect

Another dial script (with chat) works.

Comment 2 Michael K. Johnson 1999-08-04 15:21:59 UTC
The expect script isn't closing any file descriptors by any
chance, is it?  Could you post the expect script (with sensitive
parts replaced with "x" characters, of course...) for us to
look at?

Comment 3 Michael K. Johnson 1999-09-20 01:46:59 UTC
Re-open this bug and include the script we need to use in order to
look into the bug if you like.

Comment 4 Michael K. Johnson 1999-09-20 14:36:59 UTC
Thanks for sending the script.  I don't see anything immediately
obviously wrong about it.

Can you check and see if this is a problem with the latest pppd
from RawHide?

Comment 5 Michael K. Johnson 1999-11-22 18:44:59 UTC
I'm assuming that this was fixed, since I haven't heard back since I
proposed the latest ppp packages as a fix in september.  If that's not
the case, please try the latest ppp packages from the 6.1 errata, and
if that doesn't work, please re-open this bug report and say so.  Thanks!
