Add -c <command> option to force a specific command This change adds a -c option to dropbear, to force the session to use a specific command, in a similar fashion to OpenSSH's ForceCommand configuration option. This is useful to provide a simple fixed service over ssh, without requiring an authorized key file for the per-key forced_command option. This setting takes precedence over the channel session's provided command, and the per-key forced_command setting. Signed-off-by: Jeremy Kerr <[email protected]>
