[SOLVED] Remote Access to a home Arch system behind the router.

gopichand · 2011-09-27 16:06:53

Hello,

I am trying to remotely access my home Arch system from school. I did try doing something and this is what I did:

1. Used DynDns and NO-IP to setup a free domain, I thought NO-IP script was easy to run so I tested this on NO-IP.
2. I then installed Openssh.
3. Then I have setup the Port forwarding on the router to point to my ssh port (change from 22).
4. I tried to ping, the domain name from NO-IP with no response.

What I want to ask is... is there any better way of doing this?
I dont need a desktop access, simple ssh should do for now.

Thank You
Gopi

Can you access the remote machine using IP address only? I know that normally DNS also takes a bit to propagate, so depending on how long you waited that could be an issue.

I waited till the time, it said time-out/no-response. It took may be a couple of mins.
I tried only with IP, but It was not accessible either. I might have done something wrong, so wanted to know whether there are any other methods I can try.

Thanks for your reply lifeafter2am.

Is your router setup to respond to pings? I know my system is setup for remote access (ssh and apache) which both work but my router is setup to reject ping messages so a ping fails. Have you tried just sshing into your box?

can you acess ssh server from LAN side? i use Dyndns it works fine for me.

I have not checked whether my router was not accepting any pings.
I used my local ip to login via ssh from my android.

First thing first : What is the command (and parameters) you're using and what is the exact error message when you try to connect to your computer ?

Also, is your computer on a fixed ip address ? Because if it's still on DHCP, the address will change after a certain time making your port forwarding on your router pointing to the bad address.

Is the ssh daemon running on your computer ? Have you added it in the daemon array in /etc/rc.conf ?

Does your /etc/hosts.allow look like this:

ewaller@odin:~ 1214 %cat /etc/hosts.allow
#
# /etc/hosts.allow
#
sshd: all
# End of file
ewaller@odin:~ 1215 %

I believe hosts.allow is no longer used since tcp_wrappers support was dropped in July

You seem to be right Where have I been?

To the OP. Have you tried this advice: https://wiki.archlinux.org/index.php/Se … shooting_2 ??

Also, you state you installed it... Do you start it?

Is there a chance your school blocks traffic on port 22?

Sorry - re-read your initial post. Have you tried routing traffic via a port that's unlikely to be blocked eg 443?

OK, I have solved this by this process. Will work only if the router supports the DynDNS. I am assuming that you have created a DynDNS account, its free for 2 domains. I also had to make my computer use STATIC IP from my router, just specify any IP address outside the DHCP range.

1. On the router, add the details about the DynDNS account. On my Belkin Router, I had to go to Firewall -> DDNS -> DynDNS and give the details and also enable it.
2. By doing the above step, we don't have to install the client for DynDNS.
3. On the router again, setup the port forwarding, again (on my Belkin Router) go to Firewall -> Virtual Servers -> Add the IP and the port numbers, I had to use the same number for both the incoming and the private port, though for other routers the number can differ?
4. On the computer, I installed the openssh and then changed the login port to the one specified in the router for forwarding.
5. Make the router and ssh logins as safe as possible. I understand that opening the router is not safe so I have to warn you.

I can now login using my DynDNS domain name from anywhere woohoo!
