Backup Central

How does the rsync backup on Linux clients validate the ssh connection? I can’t figure out how to get the password for the connection into the command line.
Also, has anyone tried backing up a Mac OSX box?

You don't need a password. Just set up passwordless authentication using DSA
public keys.

basically, run:
ssh-keygen -t dsa

then take the ~/.ssh/id_dsa.pub file, put it on the remote machine in the
.ssh subdirectory of the home directory of the user you want to log in as;
and rename it to authorized_keys.
(so ~/.ssh/authorized_keys)

make sure that your /etc/ssh/sshd_config file allows public-key logins (so
you'll need "RSAAuthentication yes").

if you're going to log in as root (the default and simplest way.. tho there
are more secure methods); you'll also need to enable root logins in your
sshd_conf. (I guess most distros leave this on, tho around here we turn it
off for security reasons. you should log in as an ordinary user and then su
to root).

test this all out by trying to ssh (as the user that backuppc runs as) to
the remote box. it should just log you in. if you're having problems;
consult your system logs on the remote side, and do 'ssh -v user < at > host' to
get more debugging info.

If you don't want to use passwordless authentication, you can use
ssh-agent. Look at :
- Keychain http://www.gentoo.org/proj/en/keychain.xml and
http://www-106.ibm.com/developerworks/linux/library/l-keyc.html
- http://www.akadia.com/services/ssh_agent.html
- http://www.wlug.org.nz/SSHKeys

Then you tell BackupPC to use a little script like

/home/backuppc/ssh-auto :
#!/bin/sh
. /home/backuppc/.ssh-agent-info
/usr/bin/ssh -q "$ < at > "

instead of ssh. (Just change the "SshPath" parameter from config.pl)

I too am backing up OS X clients w/out a problem now. I switched to tar =20=

but I'll go check out rsync again. However I had some key excludes I =20
needed to add in addition to what you've got to make things work:
$Conf{BackupFilesExclude} =3D =20
['/Network','/private/var/automount','/private/var/run','Caches','/=20
Trash','/dev','/Developer','/Users/Tina/Music','/Applications'];
