ssh into home network
I am trying to ssh from my computer at work into my home PC. My work computer is running mac os x 10.6.3, home PC is running ubuntu. At home I have multiple PC's hooked up through a router and modem. I have gone into the router settings and set up port forwarding to forward ports 22 and 175 to my linux pc. (22 is the standard ssh port, I set 175 as well for testing). I then got the external IP of my home network (Which I believe is pointing to the router?), 66.***.***.***. Trying to run ssh from my work computer I get Code:
ssh 66.***.***.*** -p 22 ssh: connect to host 66.***.***.*** port 22: Operation timed out ssh 66.***.***.*** -p 175 ssh: connect to host 66.***.***.*** port 175: Connection refused I also tried telnet Code:
telnet 66.***.***.*** 175 Trying 66.***.***.***... telnet: connect to address 66.***.***.***: Connection refused telnet: Unable to connect to remote host telnet 66.***.***.*** Trying 66.***.***.***... telnet: connect to address 66.***.***.**: Connection timed out telnet: Unable to connect to remote host telnet 66.***.***.*** 22 Trying 66.***.***.***... telnet: connect to address 66.***.***.**: Connection timed out telnet: Unable to connect to remote host All of these commands going to any port other then 175 have a 30-60 second delay before saying connection timed out. The connection refused message on port 175 comes immediately after typing the command. ping does work, gives results like Code:
ping 66.***.***.*** PING 66.***.***.*** (66.***.***.***): 56 data bytes 64 bytes from 66.***.***.***: icmp_seq=0 ttl=116 time=23.313 ms 64 bytes from 66.***.***.***: icmp_seq=1 ttl=116 time=23.737 ms 64 bytes from 66.***.***.***: icmp_seq=2 ttl=116 time=23.214 ms 64 bytes from 66.***.***.***: icmp_seq=3 ttl=116 time=23.381 ms Can anybody help? I am not sure what is going wrong. |

Do you have a router? If so you need to open your ports in your router's firewall.

I did set up port forwarding on my router to send ports 175 and 22 to the ubuntu machine.
Also, I found out that sshd was not listening to port 175, so I fixed that. However, now I get the operation timed out error on both ports 22 and 175, so I am inclined to believe that I am getting through the router but not getting into the machine, otherwise changing settings on the ubuntu machine shouldn't change the error. However, ssh to the ubuntu machine from others on my home network works so it's only getting in from outside that is a problem. Is there a firewall in ubuntu that is by default on that I would have to change settings on to make this work? |

Ubuntu has all the ports close by default. It has iptables as a firewall.
To open ports you can use a GUI utility like Firestarter or you can use the command line utily ufw that is installed already. These are just front-end managers. Here's is an example to some configuration using ufw (uncomplicated firewall) Another source Last edited by Aia; 08-05-2010 at 01:00 PM.. |

I think you have some problem with your router not Ubuntu. Try these: 1. Reboot your router. 2. Just in case, under Ubuntu restart SSH: Code:
sudo /etc/init.d/ssh restart 3. Try connecting again. By the way did you try to SSH to your work computer from your home Ubuntu? Try SSH to your work computer and when in it try to SSH back to your home Ubuntu. ---------- Post updated at 10:23 AM ---------- Previous update was at 10:17 AM ---------- Quote:

If all of the ports were closed wouldn't it block an ssh connection from another computer on my home network? I mentioned before that sshing around within my home network works fine, it's just coming in from outside that does not. Or does iptables distinguish between local and global connections? @daynews I don't believe I can ssh in to my work computer from home. At work it's on a fairly large network and I have no access to the networking routers or anything to do port forwarding. If the problem is on that end I am probably out of luck. I will try changing the rules on iptables when I can. |

Don't mess with iptables rules before you figure your remote issue. You said that you forwarded the proper ports in you router? Do you have only a router connected to you system, or there's any other device in the middle? |
