NAME

SYNOPSIS
ssh_filter_btrbk.sh [-s|--source] [-t|--target] [-d|--delete] [-i|--info]
[-p|--restrict-path <path>] [-l|--log] [--sudo]
DESCRIPTION
ssh_filter_btrbk.sh restricts SSH commands to btrfs commands used by btrbk. It examines
the SSH_ORIGINAL_COMMAND environment variable (set by sshd) and executes it only if it
matches commands used by btrbk. The accepted commands are specified by the "--source",
"--target", "--delete" and "--info" options.
Note that the following btrfs commands are always allowed: "btrfs subvolume show", "btrfs
subvolume list".
Example line in /root/.ssh/authorized_keys on a backup target host:
command="ssh_filter_btrbk.sh --target --delete --restrict-path /mnt/btr_backup" ssh-rsa AAAAB3NzaC1...hwumXFRQBL [email protected]
