How to use ssh if remote host does not support echo command (Hetzner Storage Box) #1442
Description
Do you have any idea how I can use backintime if rsync and standard file operation commands are available but no echo command which backintime is using to check the connection?
ssh -o PreferredAuthentications=publickey -p 22 -o ServerAliveInterval=240 -o IdentityFile=/home/[user]/.ssh/[id]_rsa backup@[my-local-ip] echo "Hello"
fails with
Command not found. Use 'help' to get a list of available commands.
ssh -o PreferredAuthentications=publickey -p 22 -o ServerAliveInterval=240 -o IdentityFile=/home/[user]/.ssh/[id]_rsa backup@[my-local-ip] ls
works fine.
