Re: [hylafax-users] JobControlCmd not executed

[Edoardo Serra <eserra@xxxxxxxxxx>]

Hi Aidan,
	I succeded in running jobcontrol as you can see from my logs (it was a
stupid problem, during one of my tentative I removed the shebang on the
first line of jobcontrol... )

FaxQueuer[8841]: JOB 84 (...): CONTROL
FaxQueuer[8913]: JOB 84 (...): JOB CONTROL: bin/jobcontrol 84
FaxQueuer[8841]: JOB 84 (...): CMD DONE: exit status 0

BTW, I just noticed that jobcontrol is ran as the root user, is it
correct ?!?

But now I have a more serious problem which happens ONLY if I have a
JobControl script specified in etc/config; faxq CRASHES with
Segmentation fault

Here is the trace of faxq crash while sending a fax:
http://pastebin.com/m5e774660

bin/jobcontrol is VERY simple:

#!/bin/bash
echo "ModemDialCmd: \"ATS0=255;+iO0110674704;DT%s\""
/usr/bin/touch /tmp/hywbr

If I remove the ModemDialCmd line everything works fine
I also tried with echoing another parameter (I tried with "UseJobTSI:
yes" and it worked)

Anybody has clues about it ?

Tnx again for help

Regards
