Hello.
Since it was off topic, we transferred the conversation to a private
email thread. Here are the emails that were exchanged following the
last public post.

It's fine if you contact me privately. If your router is claiming to
be forwarding correctly, then I'm not sure where the hang-up would
be. Assuming you used Sharing to enable SSH, the firewall on your mac
automatically opens the port it needs. Do you have Stealth Mode
enabled, perhaps? On Tiger if you click the Advanced button on the
Firewall tab you can access the firewall log. That may provide a
little more insight into your problem. If the log is kept on previous
versions of OS X, it should be located at /var/log/ipfw.log and is
accessible using the application /Applications/Utillities/
Console.app. I hope that works for you.
Thanks,
Brent Anderson

Hi. I hope it is okay to contact you offlist. I need to get SSH
working from outside my local network. I've tried just about
everything with no success. If you don't have time to help, I really
do understand. Please don't feel obligated.
Here is what I've done so far. I want my desktop Mac to receive the
SSH requests. On that Mac, I have:
Enabled Remote Login in the Sharing prefs
Added ports 5900-5902 to the open ports in the firewall (for eventual
VNC later on)
Set my network router to forward port 22 to the local IP address of
my Mac
Then I get on my Powerbook. If I am on the local network and use the
local IP for SSH, it works fine. I can SSH to the desktop Mac, and
see everything in Terminal. If I turn on Remote Desktop on the
desktop Mac, I can use a VNC viewer to see and work with the desktop
Mac.
Then I took my Powerbook to a nearby internet cafe. I issused this
command from Terminal: ssh [EMAIL PROTECTED]
where "user" is a non-priveleged account on the desktop Mac and
"75.72.193.146" is the current IP of the WAN address on my router.
Terminal is completely unresponsvie for about a minute, and then I
get the message "Could not connect to 75.72.193.146. Operation timed
out." There is no other info and I am never asked for a password. I
tried this several times. Sometimes I used this command instead:
ssh -L 5900:127.0.0.1:5900 [EMAIL PROTECTED]
just to see if I could map ports for VNC, but that failed the same
way, no connection with a timeout.
When I got back home, I looked at the router logs. It showed that a
connection request was received and forwarded to my desktop Mac:
Sun, 01/14/2007 12:10:07 - SSH forwarded - Source:71.210.170.117,
52180, WAN - Destination:75.72.193.146, 22, LAN
Sun, 01/14/2007 12:10:07 - SSH forwarded - Source:71.210.170.117,
52180, WAN - Destination:198.162.0.2, 22, WAN
I'm not sure why there are two entries, but each attempt I made has
the same 2 lines. Maybe there is something wrong with the port
forwarding? The desktop Mac is correctly assigned at 198.162.0.2,
which is a static local IP.
Do you have any ideas? I know very little about this, but it looks to
me like everything is going fine until the request hits my desktop
Mac, which then never responds. There is a "stealth" checkbox in the
"advanced" settings in the firewall pane in Sharing prefs, but I did
not turn that on.
Again, if you don't have time for any of this, I really do
understand. Please don't feel obligated. But if you do have time, I'd
really appreciate any advice you can offer.
Thanks much.
Jacque

I have fixed it -- all because of you. :)
Sometimes when you write it all down, you start to see things you
didn't before. I had my router pointing to an incorrect local IP. I'd
swapped a couple of numbers by mistake. When I fixed that and
forwarded to the correct IP -- that is, 192.168.0.2 -- by george, it
works.
I feel both relieved and stupid. But I thank you for making me write
it all down. :) I'm happy now.

Hello.
Glad I could help.

**** END OF THREAD *****
There you have it. Everything was in place to begin with and the
first rule of tech support (Which I neglected to apply when I
responded to his query) has been justified once more: When you first
have a problem, check everything over before looking any deeper.
Sometimes it's as simple as an unplugged plug (Or, in this case, a
mistaken IP address)
Thanks,
Brent Anderson
