Connessione SSH in time out

[ildruido99]

ciao a tutti,

sto cercando di connettere il mio mac di casa (Lion) col mac dell'ufficio (SL) con ssh.

1) ho abilitato su entrambi i computer il login remoto

2) configurato su entrambi il file ssh_config come segue:

#	   $OpenBSD: ssh_config,v 1.26 2010/01/11 01:39:46 dtucker Exp $
# This is the ssh client system-wide configuration file.  See
# ssh_config(5) for more information.  This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.
# Configuration data is parsed as follows:
#  1. command line options
#  2. user-specific file
#  3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.
# Site-wide defaults for some commonly used options.  For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

su quello dell'ufficio.

se provo a connettermi usando l'IP pubblico con ssh nomeutente@IPpubblico mi da errore da entrambe le parti. dice che "connect to host x.xxx.xx.242 port 22: Operation timed out"

Non so proprio come proseguire, potete darmi un suggerimento?

NB riesco a operare su entrambe le macchine contemporaneamente perche sono colletagi tramite TeamWieaver..

beh con l'IP pubblico ti colleghi al router che ha assegnato l'IP pubblico dall'ISP, sul router devi fare un forward della porta 22 sulla porta 22 del pc, in reltà potresti forwardare qualsiasi porta del router sulla 22 del mac

la connessione va in timeout perchè il router non parla sulla porta 22.. non avendo nessun servizio in ascolto..
