[rdiff-backup-users] Limit ssh commands to rdiff-backup

[Steve Annessa]

Hello,

I'm trying to limit the commands ssh runs to rdiff-backup.

I added the commands option to my authorized_key file, and it literally runs the command listed. Has anyone successfully limited ssh commands this way with rdiff-backup? What am I doing wrong? Is it just not possible?

I push from Server_N to Server_Backup. It goes from address@hidden to address@hidden

Thank you,
