[hobbit] Getting hobbit running on FreeBSD

[Grilli, Laurent]

We are using hobbit for a while on FreeBSD (from the beta to the latest
4.1.1), we never encountered this problem. We are running two hobbits
servers on 5.4 stable. Do you get a core as soon as you start it ? 

What version of hobbit have you tried to install ? On the client side, we
needed to modify the hobbit client (already reported on this list) to be
able to check memory bigger than 2 gb and to avoid to report disk problem
with devfs at 100%

Hello all,

I've just had a try at installing hobbit on various versions (5.3, 5.4)
of FreeBSD. I was getting segvs whenever hobbitd started. After a little
work with gdb I found that allocating some buffers was based on
hostcount when hostcount was zero. I presume that on some other
platforms a zero sized malloc returns some useful amount of memory but
not on FreeBSD (it claims to return some storage rather than NULL
depending on /etc/malloc.conf but apparently not enough).

I patched hobbitd.c to increase the size (without bothering to look at
the code in any detail) and now it doesn't segv on me.

I hope this helps someone else trying to make it run.

BTW: I also had to change the group of most of the installation to my
web server group after installation. I possibly could have created the
hobbit user in the web group to get arround this but somehow it seems
tacky.

Thanks for the nice software,

Brian
