pppd hangs up with ioctl error
Last modified: 2008-05-01 11:37:50 EDT
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: /etc/ppp/ppp-up.tuhh Jun 27 11:48:36 lonestar kernel: CSLIP: code copyright 1989 Regents of the University of California Jun 27 11:48:36 lonestar kernel: PPP: version 2.3.3 (demand dialling) Jun 27 11:48:36 lonestar kernel: PPP line discipline registered.

The chat script is an expect script. What is wrong here ? The options are: modem lock crtscts asyncmap 0 The dial script is: #!/bin/sh device=/dev/ttyS1 speed="115200" exec /usr/sbin/pppd $device $speed file /etc/ppp/tuhh.options connect /etc/ppp/tuhh.expect Another dial script (with chat) works.

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?
Re-open this bug and include the script we need to use in order to look into the bug if you like.
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?
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!
