I followed the user manual's instructions to set up SSH to an Ubuntu karmic guest by port forwarding. However, this command:

Code: Select all

% ssh -p 2222 ubuntu@localhost

hangs. It connects but hangs in a read(). The host runs version 3.1.4r57640 of VirtualBox on Mac OS X. It doesn't matter if I try to connect from the host or from another machine on the network.

From the guest's console, I can ssh to the guest itself on port 22, which demonstrates that the SSH daemon is running on the guest.

What am I doing wrong? I've attached the output of "VBoxManage getextradata" and "VBoxManage showvminfo"; please let me know if I should provide ore information.

Thanks.

Switching network card type to an intel one instead might help.

Thanks for the suggestion. I tried all of the network cards, using "VBoxManage modifyvm foo --nictype1" and replacing "pcnet" with "e1000" in the "setextradata" keys where appropriate. All behaved the same way: ssh to the guest hangs in a read().

Regards.

Try running ssh -dd -p xxxx localhost
and show that output. Also exactly which os x ?

I've attached the output of "ssh -vvv" (not "ssh -dd" because my SSH doesn't take that option). The exact command-line I used is at the top of the attachment.

The version of OS X is 10.5.8.

Thanks.

First of all temporarily remove those id_rsa and id_dsa files as at least id_rsa looks corrupt , then retry that command again

Same result:

Code: Select all

Any firewall running in the guest?

baf wrote:Any firewall running in the guest?

Nope. This is a small Ubuntu karmic system, which I created with ubuntu-vm-builder:

Code: Select all

% sudo ubuntu-vm-builder kvm karmic --variant minbase --addpkg sudo --addpkg openssh-server --addpkg openssh-client --raw /tmp/ubuntu-karmic-bootstrap.raw

Thanks.

I'm a maroon: the network interface was not properly configured in the guest, probably because of broken udev rules. Thanks, baf, for your replies.

Hey,
I am having the same issue, I could not able to connect to guest through ssh terminal.

ssh -p 2222 xxx@localhost
ssh: connect to host localhost port 2222: Connection refused

Where xxx is user id.

Can you help me in resolving this issue.
Find the getextradata and showvminfo in attachment.

I could able to get through it by using the following commands.

VBoxManage modifyvm "Ubuntu" --natpf1 "guestssh,tcp,,2222,,22"
