any luck with the ProxyJump config option? I use this in my BackupPC user's ~/.ssh/config to keep the BackupPC config as clean as possible. See, e.g., https://wiki.gentoo.org/wiki/SSH_jump_host#Multiple_jumps Probably, in your case it would be something like Host client HostName 192.168.1.243 ProxyJump 192.168.1.243 HTH, Alex > thank you, > greg > > > _______________________________________________ > BackupPC-users mailing list > BackupPC-users@lists.sourceforge.net > List: https://lists.sourceforge.net/lists/listinfo/backuppc-users > Wiki: https://github.com/backuppc/backuppc/wiki > Project: https://backuppc.github.io/backuppc/ >
