[monit] Issue monitoring winbindd

[Dimitri Yioulos]

Good Monday to all (is "Good Monday" an oxymoron?).

I've installed monit on a CentOS 5.2 box to keep an eye on winbind (a 
component of samba), which is used in conjunction with our VPN for 
authentication purposes.  Note that I am not running the smb component of 
samba, as I'm not looking to do any file sharing.  This scheme works fine; 
VPN authentication has worked fine for the past three years.  Of course, my 
purpose for using monit is to make sure that the winbind daemon, and thus the 
VPN, is always available.

Here's the winbind directive in monirc or monit.conf:

check process winbindd with pidfile /var/run/samba/winbindd.pid
   group samba
   start program = "/etc/rc.d/init.d/winbind start"
   stop  program = "/etc/rc.d/init.d/winbind stop"
   if failed host 192.168.1.5 port 139 type TCP then restart
   if 5 restarts within 5 cycles then timeout

Pretty straighforward.

If I stop winbind, this is what monit reports in monit.log:

[EDT Aug  4 10:01:32] error    : 'winbindd' failed, cannot open a connection 
to INET[192.168.1.5:139] via TCP

[EDT Aug  4 10:09:41] error    : 'winbindd' service timed out and will not be 
checked anymore

I first tried monit-4.10-1, then reverted to monit-4.9-1, and both give the 
same result.  On other boxes (centOS 3.9 and CentOS 4.6), I have monit 
watching both smb and winbind (same directive for winbind) without issue.

I've searched high and low for the solution, but can't find one.  Can anyone 
help?

Thanks.

Dimitri
