On the client in /etc/sudoers did you find this line
Defaults requiretty
and change to:
# Defaults requiretty
In some distros the "Defaults" are not present so you will
have to add the line. Sudo won't run through ssh unless you
do that.
Use visudo to make the edits.

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 :

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
