Description Andrea Bernardi 2007-10-04 06:47:02 UTC
I have installed tracd on a server and with the default
/etc/init.d/tracd script don't start. The command line launched by the
start() function is the following:

start-stop-daemon --start --quiet \
               --chuid ${TRACD_USER:-tracd}:${TRACD_GROUP:-tracd} \
               --exec /usr/bin/tracd -- -d -p ${TRACD_PORT:-8000} \
               ${TRACD_OPTS:---env-parent-dir /var/lib/trac/}

I've found that if i remove the --chuid option tracd start without
problem. I think the problem is for some configuration of the server,
but I tried also in my local machine and I've obtained the same

The nasty problem is that i want to run tracd with user and group
apache instead of root and also if i've searched in the net i don't
have found a functional method.

Reproducible: Always
Comment 1 Jakub Moc (RETIRED) gentoo-dev 2007-10-04 07:35:43 UTC
Does it work if you set TRACD_USER to tracd (or just unset this in /etc/conf.d/trac)? Also, emerge --info please.
Comment 2 Andrea Bernardi 2007-10-04 07:55:48 UTC
No, don't work if I set user to TRACD_USER to tracd and if I unset TRACD_USER and TRACD_GROUP. Start only without --chuid option.

I list the 'emerge --info' of my local machine where also tracd don't start if I want to start with a different user (like tracd).

emerge --info

stat $(getent passwd trac | cut -d: -f 6)

Comment 6 Roy Marples (RETIRED) gentoo-dev 2007-10-04 09:23:09 UTC
tracd user needs a valid home dir I guess. Try setting it to /var/lib/trac

This is probably not an issue with start-stop-daemon
Comment 7 Julien Allanos (RETIRED) gentoo-dev 2007-10-04 09:42:33 UTC
Here on my box, tracd has /dev/null as home too, and the daemon starts fine.
Comment 8 Roy Marples (RETIRED) gentoo-dev 2007-10-04 09:55:15 UTC
OK, the issue could be that apache needs write access to /var/lib/trac then, which it clearly doesn't
Comment 9 Andrea Bernardi 2007-10-04 09:59:01 UTC
No, also if I set the home /var/lib/trac but don't start with --chuid. Maybe is
caused because tracd is launched via python interpreter. Without --chuid this
is result of ps aux:

root     24049  0.0  0.4   8380  4920 ?        S    11:36   0:00
/usr/bin/python /usr/bin/tracd -d -p 80 --env-parent-dir /var/lib/trac/

I also set tracd:tracd on permission on tracd but start always with user root.

Now I do the proof on my box without apache, and search only to launch tracd with a different user.
Comment 10 Roy Marples (RETIRED) gentoo-dev 2007-10-04 10:13:23 UTC
Try this

su - apache
/usr/bin/python /usr/bin/tracd -d -p 80 --env-parent-dir /var/lib/trac/

Then you should get a nice error message
Comment 11 Andrea Bernardi 2007-10-04 10:32:28 UTC
Hmmm.. maybe this is a little problem:

melchizedec ~ # su - apache
This account is currently not available.

and also

melchizedec sbin # su - tracd
This account is currently not available.
Comment 12 Julien Allanos (RETIRED) gentoo-dev 2007-10-04 10:34:49 UTC
This is because these users have /sbin/nologin as shell.
Comment 13 Andrea Bernardi 2007-10-04 10:41:35 UTC
Is this a problem? 
Now I upgraded to the last baselayout-1.12.10-r5 to see if is a bug of start-stop-daemon but the problem persists. Also from command line how can I start tracd with a user unlike root?
Comment 14 Jakub Moc (RETIRED) gentoo-dev 2007-10-04 11:33:49 UTC
(In reply to comment #12)
> This is because these users have /sbin/nologin as shell.

No, it's not a problem, but you need a valid shell *temporarily* to be able to su - to that UID. I still can't reproduce your issue.

Comment 15 Andrea Bernardi 2007-10-04 13:53:31 UTC
Ok, if in your box the daemon starts fine maybe is my erroneuos configuration in some script that I haven't taken in consideration.

Thank you very much for the help. I think to close the bug.
Comment 16 Julien Allanos (RETIRED) gentoo-dev 2007-10-22 06:45:28 UTC
So what do we do? CANTFIX?
Comment 17 Roy Marples (RETIRED) gentoo-dev 2007-10-22 07:13:49 UTC

And reporter thinks it's a config issue on his side.
Comment 18 Andrea Bernardi 2007-10-23 11:01:33 UTC
I didn't try other things, but if in your box the daemon starts fine is surely a my configuration problem. I close the bug.

Thanks you very much for the help.
