Re: [expert] SSH Server problem *SOLVED* (sort of)

[Joćo Candido Araujo Milasch Filho]

Well. I got an answer to my problem. About a year ago, my adsl provider 
blocked about all reserved ports, and thats why I can't use'em. Although 
I told you before that they were unblocked by the ISP. Then, I fall on 
another problem: The work's firewall! So, I'll need to get a list of 
unblocked outbound ports. Is there any way to see what outbound ports 
are unblocked? We got some sites that scan my incoming ports. Thats not 
hard to make a program that scan for outgoing ports, but I kind of not 
have time to do so.
If anyone knows how how to look for outgoing unblocked ports, tell me, 
because the network admins dont want to just give me a port that I can 
use. ;(

Thanks all for the answers.

Anyone knows what can I do to figure out whats happening?
     

Is your isp blocking inbound traffic on port 80 to prevent web servers from
running on the network?  That would be a cruel catch 22 if it is true. 
Work only allows outbound on port 80, while home allows all inbound but
port 80.
   

Actually, it could be worse than that.  You may not even have a "real" ip 
address.  Sometime an ISP will act as subnet on the internet, in order to 
conserve IP addresses (much like a local router would do, but on a larger 
scale.)  If you're on a dial-up connection, this is most likely the case, and 
may be even if you have a "broadband" connection.  If your IP address starts 
with 192. or 10., that's a dead giveaway, but there are other reserved ranges 
as well that I don't know off the top of my head.

Can your friends ping your ip address?  If so, this is not (probably, unless 
they're really ping'ing someone else) your problem.
