Subject: Re: [BackupPC-users] Host key verification failed
Marki,
When I say "to the client from the server" I mean that am initiating SSH and
Rsync from the BackupPC server to the backup client.
I agree that it makes no sense, that's why I'm stumped and I'm writing you.
Here's an ssh into the backup client:
# su backuppc
[backuppc@piholeserver nilix]$ ssh root@192.168.14.149 Last login: Fri Nov
8 11:41:30 2019 from 192.168.14.176 FreeBSD 11.2-STABLE (FreeNAS.amd64) #0

Welcome to FreeNAS
Warning: settings changed through the CLI are not written to the
configuration database and will be reset on reboot.
root@freenas[~]#
Here is an rsync from the BackupPC server, copying a file from the client
onto the server:
[backuppc@piholeserver ~]$ rsync
root@192.168.14.149:/mnt/MandA-Server-Pool-1/Shop-Dataset/xkcd/h
ard_reboot.png ./
[backuppc@piholeserver ~]$ ls
dead.letter hard_reboot.png
Here is the config for the client:
$Conf{ClientNameAlias} = [
'freenas'
];
$Conf{PingMaxMsec} = 300;
$Conf{RsyncShareName} = [
'/mnt/MandA-Server-Pool-1/Shop-Dataset'
];
$Conf{XferMethod} = 'rsync';
$Conf{RsyncSshArgs} = [
'-e',
'$sshPath -i ~/.ssh/id_rsa -l root'
];
$Conf{XferLogLevel} = 5;
And lastly, here is the log from the failed XFER
