[Freeswitch-users] Compiling under SmartOS

Wed Sep 9 01:54:13 MSD 2015

Darren,

if the zone has the proc_clock_highres privilege, you can assign it to
the freeswitch user:
  usermod -K defaultpriv=basic,proc_clock_highres frsw

after that, under "su - frsw", FreeSWITCH can start.

But launching it as root with "-u frsw -g frsw" causes the same
coredump, as timerfd is unavailable for some reason. This needs
further investigation.

Also inside a zone, -rp does not have any effect on the process
priority, because this needs another privilege: PRIV_PROC_PRIOUP or
PRIV_PROC_PRIOCNTL  (see privileges(5)).

So, there are still obstacles, but we're getting there slowly. But it
looks like you anyway have to have administrative access to the global
zone in order to run FreeSWITCH in a SmartOS zone. So, hosting it at
Joyent doesn't look realistic. Still, it's a very attractive platform
because of its lightweight zones and nice network performance and
built-in ZFS. Soon I will have a test physical server with SmartOS in
my lab, and I can let the interested people access it and test or play
around.

cheers,
stanislav
