For some time now i have been running BackupPC 3.1.0 on CentOS 5.1
x86_64 however after upgrading to CentOS 5.2 BackupPC will not start.
"sudo /etc/init.d/backuppc start" return OK but there is no BackupPC
processes.
This fails also.
# sudo -u backuppc /usr/bin/BackupPC -d
# echo $?
0
This succeeds, but of course does not fork.
# sudo -u backuppc /usr/bin/BackupPC
So for some reason after the CentOS 5.2 upgrade it will not fork into
the background.
I have run the perl debugger over it and up until the fork everything
is fine.
Nothing appears in the LOG.
With some help from the BackupPC list i have narrowed the problem down
to the NSS config, I use LDAP to resolve users and groups.
In /etc/nsswitch.conf this is what is there and was there with CentOS
5.1, with this config BackupPC will not background.
<snip>
passwd: files ldap
shadow: files ldap
group: files ldap
<snip>
However, with this in nsswitch.conf the service will background.
<snip>
passwd: files ldap
shadow: files
group: files ldap
<snip>
Apparently this has been seen to affect dhcpd too, but with the
"services" nss database.
Any ideas on this? What has changed between 5.1 and 5.2?
