SSH_CMD_ARGS: not used by SCRIPT_BEFORE nor SCRIPT_AFTER

[cyril23]

• Background: I need to force IPv4 connection to my server, both in rsync and ssh.
  • The server IP address may change sometimes. Therefore I need to use its FQDN as REMOTE_HOST.
  • The REMOTE_HOST has both A and AAAA DNS records
  • The REMOTE_HOST ssh server listens to SSH connections in both IPv4 and IPv6
  • Because of firewall settings in a project I may connect via IPv4 only to the REMOTE_HOST
• When using rsync, I can just pass the -4 Parameter to enforce IPv4 connection, e.g. ARGS: '-a4 --delete --no-o --no-g' and use SSH_CMD_ARGS: '-o StrictHostKeyChecking=no, -o AddressFamily=inet' which works perfectly
  • -4 prefers IPv4 connection for rsync, see https://linux.die.net/man/1/rsync
  • AddressFamily=inet enforces IPv4-only connection for ssh, see https://linux.die.net/man/5/ssh_config
• But for the SCRIPT_BEFORE and SCRIPT_AFTER the SSH_CMD_ARGS is not used actually within the ssh command. Instead, a hardcoded -o StrictHostKeyChecking=no is used

I have tried to come up with a solution in main...LogicsSoftwareGmbH:ssh-deploy:main but unfortunately can't test it because I can't get my Github action to use my code actually.
