[LDM #YBA-192887]: [LDM] dm not logging to ldmd.log and not receiving data

Hi Nitza,

Are you sure you are not receiving the observational data in the IDS|DDPLUS
datastream?  It is likely that you are receiving the data and it is not
being processed.

> Beside that,  ldm is not logging ldmd.log so I can`t  check the error.

OK.  The first thing to do is get LDM logging working.

This is the likely cause of your LDM logging not working.  Our recommendation
is that SELINUX either be disabled, or setup to be permissive.  The mode
that SELINUX will be in is set in /etc/selinux/config.  We advise that your
setup look like:

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.

NB: after changing the setup in /etc/selinux/config, you will need to
reboot for the change to take effect.  'root' can change SELINUX to
permissive mode by executing 'setenforce 0' from the command line,
but a reboot is needed to set it to 'disabled' after setting SELINUX
to 'disabled' in /etc/selinux/config.

The logging problem is likely due to the current setting of SELINUX.

> I really appreciate any help.

The next thing is to  tackle the problem of processing the data you might 
be receiving.  We can address that after you have LDM logging working.
