[Cialug] Remote Access

Mon Aug 14 09:42:18 CDT 2006

If you can SSH while on your internal network then we know sshd is setup and
working correctly.

Only things left to check (that I can think of) is to double check your port
forward is pointing to the correct internal IP address for your Linux box.
And to double check your WAN IP address on the router.

Also are you always trying to SSH from the same external location (ie: work,
school)?  It might be that port 22 is being blocked on that end.  Outbound
22 was blocked at my office for a time as well.

If you want you can email me off list with your WAN ip and I can try to SSH
from here (don't need any login info, just to see if I can establish a
connection).
