[Fedora] Advanced Control cannot connect to remote client.

FAH provides a V7 client installer for Debian / Mint / Ubuntu / RedHat / CentOS / Fedora. Installation on other distros may or may not be easy but if you can offer help to others, they would appreciate it.

[Fedora] Advanced Control cannot connect to remote client.

Post by cybersteel8 »

I have been running F@H on my Windows PC for many weeks now, and it's been working perfectly fine.
I am using the Advanced Control and I see that I can add a new computer to monitor from here, so I got my Fedora machine set up with the FAHClient and that's up and running too!
I am running and folding successfully on the Fedora machine, and I have set up its local firewall and FAHClient's config to allow access to the web panel. On my Windows machine, I can connect to the web panel perfectly fine and I can see the Fedora machine folding. Great!
However, for some reason, the Advanced Control panel on my Windows machine cannot connect to the FAHClient running on the Fedora machine. I have the port set as default, 36330, and I have successfully tested the port opening with telnet. The Windows machine can telnet to the FAHClient running on the Fedora machine over port 36330 successfully.
Yet, the Advanced Control panel just refuses to establish a connection to the client.

Is there anything I've missed here? What could be going wrong?

Have you configured the remote linux advanced control (if using) to allow remote connections? ... If using Advanced control on it you will need to Configure the Connection tab to allow your windows machine network address to access (with/without password) ... Not sure how to set this up without Advance Control in Linux - guess it will be some form of config edit but one of the linux gurus will be able to advise.

As a general rule, on all Windows machines, the network must be private (not public).
On the Linux (remote) machine, the config should look like this:

Code: Select all

 <config>
(...)
<!-- HTTP Server -->
<allow v="127.0.0.1 IP of the Windows machine, or IPs, or mask"/>
<!-- Network -->
<proxy v=":8080"/>
<!-- Remote Command Server -->
<command-allow-no-pass v="127.0.0.1 IP of the Windows machine, or IPs, or mask"/>
(...)
</config>
The remote FAH must be restarted after any change in its config.

This is what I was missing, adding this worked. Thank you for your help!
