Non standard ssh port

[Tim Haines]

Hi there,

I've tried changing the ssh port on my vm to 30002, but after I do
that, I can no longer get vagrant to talk to it.

I've added the port mapping in the Vagrant file, like so:

config.vm.forward_port("ssh", 30002, 2222, :auto => true)

Is there anything else I need to do get vagrant to reload/provision/
ssh successfully after that?

Cheers,

Tim.

Are you sure iptables is not blocking that port? The default ruleset
will assume the default port.

Did you configured ssh to run on the port 2222? If not you are then forwarding a port with doesn't have any service listening on.

[Marco De Bortoli]

Ops sorry actually the configuration you wrote, is forwarding the guest port 30002 to the host 2222 one which sounds obviously even more strange to me.

By default a ssh forwarding with default ssh service configuration should look like this:

config.vm.forward_port("ssh", 22, 2222, :auto => true)

Where 22 is the default ssh port listening in the guest and 2222 the forwarded port in the host machine.

Does it make sense?

Thanks for the responses Nathan and Marco,

I know the default is config.vm.forward_port("ssh", 22, 2222, :auto => true) - I changed the 22 to 30002.

Also, I've checked the iptables are configured for 30002 to be open, and restarted ssh on the vm after I made the port change.

So it sounds like there's not anything obvious that I'm missing?  It appears that vagrant isn't observing the ssh port forwarding rule, but I can't be sure that's what is going on ..

That's indeed the problem Tim.

It should not like this:

config.vm.forward_port("ssh", 30002, 2222, :auto => true);

but like this

config.vm.forward_port("ssh", 22, 30002, :auto => true);

paremeters in order

config.vm.forward_port([forwarding rule name], [guest port to be forwarded], [host forwarded port], [conflict auto resolve]);

I hope it helps.

Cheers

Hi Marco,

Perhaps I didn't explain well.  On the VM itself, I don't want to use port 22 as the ssh port, I have changed it to 30002 on the VM.  So when I set up port forwarding, instead of the host forwarding 2222 to 22 on the vm, I want the host to forward 2222 to 30002.  Does this make sense?

Oh ok now that make sense I think I misread your first email as well... I have a clean box starting up right now... let me see if I have the same problem. Bear with me.

[Marco De Bortoli]

Bad news... it worked like a charme on mine, possibly even better than with the standard forwarding.

The only thing I can think about is that maybe you have another service running on that port.

Did you try to change it to something else?

[Tim Haines]

Hi Marco, 

Did you do anything apart from set up the forward_port rule as I did below, and configure it in ssh and iptables in the VM?

Thanks for giving it a shot.

Tim.

Actually as per Vagrant's base documentation I disabled both iptables and selinux. I'm currently running a CentOS 5.5 64 bit if it might of any relevance...

What's you host? Win, Mac or Linux? what error message you get if you manually try to do:

ssh vagrant@localhost -p 30002
