SCP bad configuration


I’m just trying to share data using scp between GVLs and I get an error of:

/etc/ssh/ssh_config: line 55: Bad configuration option: x11uselocalhost
/etc/ssh/ssh_config: terminating, 1 bad configuration options
lost connection

I am able to use scp to transfer files from my mac to my GVL just not the other way round.
Any advice would be great! The GVL I’m currently on is


This is a configuration error that we’ve fixed by default on later GVL instances, but you can fix simply yourself.

As described in the error message, the problem is with the

X11UseLocalhost no

line in /etc/ssh/ssh_config.

You can use a command line text editor like nano to fix this file by running the command:

sudo nano /etc/ssh/ssh_config

You will need to add a # symbol at the start of the line:

X11UseLocalhost no

to form:

# X11UseLocalhost no

Then quit nano with Ctrl+X, making sure to follow the prompts to save the file.

You should then be able to SSH and SCP just fine between instances.

Oh that’s great, thanks! I’d used pico thinking I needed to change the no to yes, I was so close!

Thanks again, that’s all working perfectly now

So close, not a bad guess at all!

Glad everything’s working now.

I seem to have a new problem! Just went to change the x11 part on another GVL ( but my whole file system seems to be read-only!!! Not sure how I’ve managed to achieve this one - please say it can be fixed?

Oh no, it’s actually all my GVLs…

Hi Gemma - we had a small problem with the underlying storage at Birmingham. A hard-reboot issued from should fix the read-only issue.

I’ve done that on one, but now when I try to connect it just times out but I can still connect to the other IP addresses which I didn’t reboot!

We’re looking further into this, I’ll update you ASAP.

I have exactly the same issue as Gemma! ( at Brum)


Hi Mark - We’re working on this right now, and I’ll update here as soon as I have useful information for you.
