[TIGGE #LJA-831211]: Fwd: [Fwd: Re: ldm can not write to /home/ldm/logs or /TIGGE/dasg011]

Hi Doug,

Typically we see that sites don't:

- configure /etc/syslog.conf
- have not turned off SELINUX
- have not performed the final LDM installation step (which is the
  'make install_setuids' step that needs to be done as 'root')
- there is some write permission issue with the LDM log file
  or LDM logs directory

The thing to do at this point is test to see if logging should be
working:

<as 'ldm'>
logger -p local0.debug 'test of LDM logging'

After running 'logger', check the size/contents of ~ldm/logs/ldmd.log.
If the test log message is not in the file, recheck the /etc/syslog.conf
settings (or /etc/rsyslog.conf on newer Fedora systems); and/or check to
make sure that SELINUX is disabled (in /etc/selinux/config, SELINUX needs
to be set to disabled or permissive; if this needs changing, the
machine has to be rebooted for the change to take effect).

I these do not work, please send us the contents/output of:

/etc/syslog.conf
/etc/selinux/config

ps -eaf | grep syslog

ls -alt ~ldm/logs

No worries.
