Dear developers.

We use OOD 3.1.10 and turbovnc-3.1.1-1.  
We are having trouble with what is written in the following thread:

> [@Websockify timeout?](https://discourse.openondemand.org/t/websockify-timeout/3389/8):
>
> I had the same issue with OOD 3.1.4. I solved the issue by setting the timeout to 10 seconds. This may be caused by using a slow ARM CPU.

Due to the low CPU power of the machines with container we use, the 5 second time limit of VNC is often too short. So every time I install a new OOD I update it to a higher value manually, but sometimes I forget.

```auto
# ood_core/batch_connect/templates/vnc.rb
elif [$counter -ge 5]; then
  # timeout after ~5 seconds
  echo "[websockify]: timed-out :(!" >&2
  return 1

```

So, is it possible to modify OOD so that I can change the VNC timeout in seconds using a variable ?  
For example, variables could be written in files under /etc/ood, or in submit.yml for each application.

Best,

4.0 is going to have a config/environment variable. You’d use the config `websockify_timeout_seconds` just like other vnc batch\_connect configs in your submit.yml.erb or cluster.d file. The environment variable you could set it all sorts of places.
