how to test local ssh server without asking external help
Hi guys,
I have a question about my ssh server. My network consists of a router
implementing NAT and 2 computers in LAN. I have the ssh server on my
desktop and try to access it from my laptop. When I ssh to the server
using its private address all works like a charm but when I try to use
the external IP, it doesn't. And yes, the router has port forwarding
enabled for that port.
The error I get is:
pablo@mio:~$ ssh -vvv XXXXX.joe.nu
OpenSSH_5.1p1 Debian-5, OpenSSL 0.9.8g 19 Oct 2007
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug2: ssh_connect: needpriv 0

debug1: identity file /home/pablo/.ssh/id_rsa type -1
debug1: identity file /home/pablo/.ssh/id_dsa type -1
ssh_exchange_identification: Connection closed by remote host
pablo@mio:~$
I don't get the error if I use the private IP:
pablo@mio:~$ ssh 192.168.1.10
pablo@192.168.1.10's password:

Any ideas why: ssh 192.168.1.10 would work, but ssh external.ip.here
doesn't? I can't test if my ssh server works (or web server, or
ddbb server) except if I ask for external help?
Thank you in advance,
