Re: [BackupPC-users] Error: Unable to connect to BackupPC server

Hi Craig,
Thank you very much for your reply.
I checked the premissions on /var/log/BackupPC/BackupPC.sock and they seem fine:
[root@backup3 BackupPC]# ls -la | grep BackupPC.sock srwxr-x--- 1 backuppc backuppc 0 Sep 17 04:01 BackupPC.sock
Apache is running with user backuppc and group apache, so it shouldn't have any issues reading BackupPC.sock. Now, this leaves me with the option that apache is looking on the wrong place for the socket file.
How can I check to see where apache is looking for the socket file?
Kind regards, --Bruno

Bruno,
The communication with the BackupPC server happens via a unix-domain
socket. That's a special file that allows the server (BackupPC) to
listen to connections from clients (eg: CGI via apache/BackupPC_admin
or BackupPC_serverMesg or BackupPC_dump).
In non-FHS installations the socket is located at TOPDIR/log/BackupPC.sock.
In FHS installation it should be at /var/log/BackupPC/BackupPC.sock.
The fact that backups are working means that programs started by
BackupPC (eg: BackupPC_dump) can in fact connect to the server.
So apache either is looking in the wrong place for the socket file
(eg, if you had an old or second BackupPC install with different paths)
or it no longer has permissions to read the socket (eg: it isn't
running as the BackupPC user).
You can also configure BackupPC to use a TCP socket (typically when
the BackupPC server and apache are on different hosts). That involves
setting $Conf{ServerPort}, $Conf{ServerMesgSecret} and $Conf{ServerHost}.
If that works, then your problem might not be completely solved since
you could still have a permission or config problem (meaning you won't
be able to access backup history and files using the CGI interface).
