Update,
I'm told to not mess with RsyncClientCmd - it's "depricated" (no source)
whatever.
So I changed this instead:
$Conf{RsyncSshArgs} = [
'-e' , '$sshPath -i /home/backuppc/.ssh/backupc_cg5_id_ed25519
root@$host ',
]
fine, now it works, almost.
That said invocation of rsync ends up looking like this :
/usr/local/bin/rsync_bpc \
'--bpc-top-dir' \
'/vol0/www/backuppc/data/' \
'--bpc-host-name' \
'hegemone.databit7.com' \
'--bpc-share-name' \
'/home/administrator' \
'--bpc-bkup-num' \

'--bpc-bkup-comp' \

-1 \
'--bpc-bkup-prevcomp' \
-1 \
'--bpc-bkup-inode0' \
5 \
'--bpc-log-level' \
1 \
'--bpc-attrib-new' \
'-e'\

'--timeout=72000'\
'--include=/home'\
'--include=/home/administrator'\
'--exclude=/*'\
'--exclude=/home/*'\
'phantom.databit7.com:/home/administrator/'\
'/'
but rsync fails to function with the error

This is hostname is added to the rsync args in a manner that causes
phantom to try to execute it's own hostname after the sshd on login:
/BackupPC/lib/BackupPC/Xfer/Rsync.pm
push(@$rsyncArgs, "$t->{hostIP}:$shareNameSlash", "/");

Greatings all, long time backuppc user, but I'm struggling to roll out
a more secure ssh system on my new install.
On a new install of backupPC 4.4.0. I setup a host as follows:
host dhcp user moreUsers # <--- do
not edit this line
phantom.databit7.com 0 databit7
The host is configured as such
$Conf{XferMethod}='rsync';
$Conf{BackupFilesOnly} = [ '/home/administrator' ];
$Conf{'RsyncShareName'} = [ "/home/administrator" ] ;
$Conf{BackupsDisable} = 0 ;
$Conf{rsyncPath} = "/opt/rsyncWrapper";
$Conf{'RsyncClientCmd'} = '$sshPath -i
/home/backuppc/.ssh/backupc_id_ed25519 -l rewt $host $rsyncPath
$argList+';
BackupPC has been restarted since the last edit. The rsyncPath is
abided by, but the RsyncClientCmd command has little bearing on the
command that gets run. The log generated is as follows:

I can confirm that ssh channel is opened, but it doesn't use the key,
so the client gives up and hangsup.
Where should these arguments be set to force ssh to use a given set of
arguments?
TIA,
Robin
