Unable to access WebUI from another PC (Linux host)

[uncovery]

Hey guys,

I just freshly setup Resilio on a PC running CentOS stream. I can access the web interface on the same PC with https://localhost:8888/ but not from another computer

I have made sure that the firewall has tcp port 8888 open (it should work, I have another service running, opened the firewall and there it works as well).

Any idea what I can check to fix this matter? Is there any setting that needs to be set to access the webUI from another computer?

thanks

Your WebUI is configured to listen to localhost only, which is only accessible from the same PC.

Either you need to re-configure it to listen on other interface (for example,  0.0.0.0:8888, which means port 8888 on all interfaces), or use some other applications that can do port forward for you.

Hi, thanks for the help.

My config file has that already:

 

  "webui" :
  {
    "listen" : "0.0.0.0:8888" // remove field to disable WebUI

This was there without me adding it.

Should that be enough?

I am a bit confused because the export of the config file does not seem to match 100% the actual settings in the client, e.g. I disabled uPnP but it's ON in the config that was exported.

Yes it's enough. Next you should use netstat to verify the rslsync is really listening to port 8888 on all interfaces:

netstat -anp

if it indeed listens on all interfaces, then I guess it's firewall,  try totally disable firewall (temporally) and test.

Thanks for the advice. I get this line in netstat:

 

tcp        0      0 127.0.0.1:8888          0.0.0.0:*               LISTEN      -

I stopped firewalld, but it still does not work.

The line from netstat clearly shows your rslsync is listening to 127.0.0.1:8888, which is only accessible from localhost.

For listening to all interfaces, It should be like:

tcp        0      0 0.0.0.0:8888          0.0.0.0:*               LISTEN      -

There might be some problems with your config file, try testing rslsync with --webui.listen option as

./rslsync --webui.listen 0.0.0.0:8888

I have this exact same problem. In config.json I have it listening to 0.0.0.0:8888, but using ss (successor to netstat), I see:

tcp   LISTEN    0      10                                      127.0.0.1:8888                                          0.0.0.0:* 

I tried using the rslsync directly, and I get no luck that way.

Update: A reboot fixed the problem...
