Stumper? bug? nsca daemon & ext. cmd. file -- not a permission issue?

[Giedrius Astrauskas]

Re: [Nagios-users] Stumper? bug? nsca daemon & ext. cmd. file -- not a permission issue?I have found comments in nsca.c code that nsca started with option -d is running as "multi process daemon" and started with option -s as "single process daemon".
Further in the comments in code there are references to multi process daemon as being "older style".
So I am running nsca with option -s

Can anybody explain what is really a difference between the two options?

Thanks.

  According to your ps output below, nsca is running as user nsca, not the user nagios and therefor does not have permission to write to the command file. Either start nsca as the nagios user or add nsca to the nagios group in /etc/group and restart nsca.

  Sorry -- had to put this project down for a few
  days... Well it's not an issue with the trailing space
  (I wish it had been that easy!)

  I'm still stuck, but you're question about whether
  nsca is running out of inetd or a daemon made me
  realize I was running in -s (single) rather than -d
  (daemon) mode.  I 've fixed that:

  nsca     24583  0.0  0.1  1596  668 ?        S  
  02:56   0:00 /usr/local/nagios/bin/nsca -d -c
  /usr/local/nagios/etc/nsca.cfg

  ...But now I get this error in syslog:

  Jan 15 03:09:31 sf1nmc1 nsca[24645]: Handling the
  connection...
  Jan 15 03:09:32 sf1nmc1 nsca[24645]: SERVICE CHECK ->
  Host Name: 'laptop', Service Description: 'BOGUS',
  Return Code: '2', Output: 'Error Message goes here'
  Jan 15 03:09:32 sf1nmc1 nsca[24645]: Could not open
  command file '/scale8/nagios/var/rw/nagios.cmd' for
  writing
  Jan 15 03:09:32 sf1nmc1 nsca[24645]: End of
  connection...

  Notice the "Could not open" -- This would make it
  *seem* more like a permission issue... but honestly,
  everyting with the CGI's and echoing directly to the
  command file works just fine (as the nagios user, and
  as the apache user).   Here is my "rw" directory:

  [root at XXXX root]# ls -la /usr/local/nagios/var/rw/
  total 8
  drwxrwsr-x    2 nagios   nagios       4096 Jan 15
  02:57 .
  drwxrwxr-x    4 nagios   nagios       4096 Jan 15
  03:11 ..
  prw-rw----    1 nagios   nagios          0 Jan 15
  02:57 nagios.cmd
  -rw-r--r--    1 nagios   nagios          0 Jan  7
  10:26 nsca.dump

  Any other ideas?

  Thanks for you help.
