I've been lucky enough to get a gentoo box at a company, but when i was doing last minute configuration through ssh. Then it stopped responding and i couldn't get in contact with the server, but everyone else can. So i think my server blocked my ip, so how do i unblock it?

Ps. I got ssh access through an other server.

Do you have iptables set up on this box? If so can you show what chains you have set up? The two that may be important can be accessed by doing an iptables -L and iptables -t nat -L.

I do have iptables installed, but it's only that one ip that can't connect to the server.

here is the output of iptables -L

Are you using portsentry or some other kind of filtering daemon?
Have you disabled iptables and try to reconnect?
Are you sure it's being blocked on your system? Could it be something on the corporate network or ISP?
Are the other systems you CAN connect from on the same network? Using the same external IP (via nat)?

With the limited information supplied, that all I can suggest.

Well i've never tried this before so i gave the information that i though was needed

I'm not using any kind of filtering daemon, i have tried to disable iptables, but that didn't help.
My server is outside of any firewall in the company, it's connected directly to an ISP, so could be the ISP, but why should they want to block the ip, i was only using ssh ?
I can't check if computers on the same network as the server can connect, but that shouldn't be interesting to know, mostly because it is meant to be remote controlled at all time.
From other computers i can connect just fine.

Sometimes if you do port scans or other activity that would look fishy to an ISP, they might block you.

To see your external IP address from a nat'd workstation, visit http://whatsmyip.net/

Well i don't know how and why there isn't a problem any more

Didn't restart any of the machines, routers or switches. But it's all working again. So i'm a happy server admin again
