Estou me aventurando além do Ubuntu pela primeira vez e escolhi o Antergos para facilitar meu caminho para o mundo mais amplo do Linux. Tudo está indo bem e o pacman está se tornando familiar, mas o autossh parece estar tendo um problema:
Em Antergos:
[tbrowne@redbrix1 ~]$ autossh -p 52222 [email protected]
usage: autossh [-V] [-M monitor_port[:echo_port]] [-f] [SSH_OPTIONS]
-M specifies monitor port. May be overridden by environment
variable AUTOSSH_PORT. 0 turns monitoring loop off.
Alternatively, a port for an echo service on the remote
machine may be specified. (Normally port 7.)
-f run in background (autossh handles this, and does not
pass it to ssh.)
-V print autossh version and exit.
Environment variables are:
AUTOSSH_GATETIME - how long must an ssh session be established
before we decide it really was established
(in seconds). Default is 30 seconds; use of -f
flag sets this to 0.
AUTOSSH_LOGFILE - file to log to (default is to use the syslog
facility)
AUTOSSH_LOGLEVEL - level of log verbosity
AUTOSSH_MAXLIFETIME - set the maximum time to live (seconds)
AUTOSSH_MAXSTART - max times to restart (default is no limit)
AUTOSSH_MESSAGE - message to append to echo string (max 64 bytes)
AUTOSSH_PATH - path to ssh if not default
AUTOSSH_PIDFILE - write pid to this file
AUTOSSH_POLL - how often to check the connection (seconds)
AUTOSSH_FIRST_POLL - time before first connection check (seconds)
AUTOSSH_PORT - port to use for monitor connection
AUTOSSH_DEBUG - turn logging to maximum verbosity and log to
stderr
[tbrowne@redbrix1 ~]$
No Ubuntu 16.04:
tbrowne@calculon:~$ autossh -p 52222 [email protected]

Eu quero usar o autossh para criar uma porta reversa para a frente, mas parece que há um erro de sintaxe sempre que eu tento qualquer coisa com ele.
Estou usando o autossh 1.4e em ambos. Plain old (não auto) ssh funciona bem em ambos. O que está acontecendo?
