Remote SSH not working

[MrSpandex]

ANSWER IS: I was attempting to connect to the external IP from within my LAN to test.

Hello,

I have SSHD running on my slackware 11.0 system. I am able to connect via Putty from my Windows box with the local IP (192.168.0.111), and I can even connect from the slackware box to itself using this same IP (192.168.0.111). What I am having trouble with is connecting to it using my external IP (68.XX.XX.XX). I cannot connect from either box. Both simply time out.

I have forwarded port 22 on my router, which I am confident should work (I forward lots of ports) to 192.168.0.111, the local LAN IP. DHCP is off.

The slackware box connects to the net just fine through Firefox and links. Its ifconfig output:

eth0      Link encap:Ethernet  HWaddr 00:D0:B7:21:A9:73
          inet addr:192.168.0.111  Bcast:192.168.0.255  Mask:255.255.255.0

Thanks in advance for any help. I <3 Slackware

i not very sure that this would help but can u ping the ip 192.xxx from 68.xxx?

That won't work as 192.x.x.x is a LAN address whereas the other is a WAN address. Is the port definitely forwarded correctly? Are you running ssh on port 22? On my router it lets you create the rule for port forwarding but it has to be activated seperately. What router are you using?

Here's what you need to do, you need to get some dns service, for that you have to set a fixed LOCAL IP, in other words, if you have four computers connected to your router then your router is most likely 192.168.0.1 and the rest go 2,3,4 so on so forth. In the router setup there's an option to give your box a fixed IP, such as 192.168.0.3 and no matter which comp is on first your IP is always reserved. Then you can get a free *.dyndns.org subdomain from Dynamic Network Services, Inc. -- DynDNS -- Welcome and that will automatically forward to your IP even if it changes the whole time.

Good luck

I don't think this will solve the problem.

Can you post your /etc/ssh/sshd_config?
Also, can you post the output of 'netstat -tulpn'?

Got my answer from another forum. It was because I was testing from within my LAN.

Sorry for all the trouble, and thanks for the advice

I am an idiot.

That old chestnut

I should have guessed, I've made that mistake myself
