I am trying to access the dashboard. Python:

```auto
import logging
import time

import ray

print("ray version:", ray. __version__ )
ray.init(include_dashboard=True, logging_level=logging.DEBUG)
iter = 0
while True:
  time.sleep(2)
  print(f"tick[{iter}]")
  iter += 1

```

Output:

Can’t find any process listening on 8265:  
`$ sudo lsof -nP -iTCP -sTCP:LISTEN | grep 8265` and `$ sudo ss -tunlp | grep 8265` come back with nothing.

There are some processes shown in `ss -tunlp`, but none of them are associated with port 8265:

Found some more information looking at dashboard.err:

I believe it is trying to create the directory, but it does not have write permissions:

Sorry about the broken links. We refactored the dashboard doc in 2.5 but the redirects are not set correctly. We’ll fix them soon.

For now, you can take a look at these two links

- [Getting Started — Ray 2.5.0](https://docs.ray.io/en/latest/ray-observability/getting-started.html)
- [Configuring and Managing Ray Dashboard — Ray 2.5.0](https://docs.ray.io/en/latest/cluster/configure-manage-dashboard.html)

Here are some questions for me to better understand your setup:

- how do you launch the cluster? Is it local, vm launcher, or kuberay?
- did you install “ray[default]”, “ray[air]”, or other ones that include dashboard component? [Installing Ray — Ray 2.5.0](https://docs.ray.io/en/latest/ray-overview/installation.html#from-wheels)

Thanks for the reply, it only seems to happen with the ray 2.4.0 package that is part of the NixOS repository. If I install ray 2.5.0 from pip it works after using patchelf to fix up the interpreter path of the gcs\_server and raylet executables.

Glad that you figured it out. Anything we should change it make it work out of box?
