Hi,
I'm using BackupPC for a while (my version is a little bit old: 3.3.1
😁) with Linux clients.
I'm trying to setup a windows client (the only windows client I have,
all others are Linux). On this windows laptop there is a firewall
closing all the ports and I have opened:
- icmp echo for the IP of my backuPC server (and only for this IP)
- rsync tcp (873) for the IP of my backuPC server (and only for this
IP)
However Backuppc returns always an authentication problem on the
windows client:
"Got fatal error during xfer (auth failed on module drivec)
First, it's worth mentioning that this is happening at the rsyncd level,
where the client is failing to authenticate.
From the Backuppc server, logged as backuppc, I can manually (from a
terminal prompt) run the rsync command to the laptop client,
authenticating with the user name and password specified in the
RsyncShareName. So rsync seams to work.
RyncdPasswd and RsyncdUserName need to be set, of course
So I have 2 questions:
1) is there additional ports required by BackupPC for a windows client
(others than "icmp echo" and "rsync" ?)
No.
2) is there a way to set BackupPC in a more verbose mode to debug these
exchanges ?
The logs should suffice for telling you what command line is being sent,
though see above. Note that you probably want to turn on verbose
logging at the rsyncd side to see what credentials are actually being
sent.
While you're at it, unless your usernames and passwords are drawn
entirely from the ASCII character set, you may be running into character
translation issues.
The setup I'm using was functional with the previous laptop of this
user but the firewall setup was more permissive. I've just duplicated
the files for his new laptop to create a new configuration, rewrote
several times the RsyncdUserName and RsyncdPasswd fields to track a non
printable character... with no final success.
Thanks for your advices.
Patrick
