Syncthing
HOW DO I ACCESS THE WEB GUI FROM ANOTHER COMPUTER?
The default listening address is 127.0.0.1:8384, so you can only access the GUI from the same machine. This is for security reasons. Change the GUI listen address through the web UI from 127.0.0.1:8384 to 0.0.0.0:8384 or change the config.xml:
<gui enabled="true" tls="false">
<address>127.0.0.1:8384</address>
to
<gui enabled="true" tls="false">
<address>0.0.0.0:8384</address>
Then the GUI is accessible from everywhere. You should set a password and enable HTTPS with this configuration. You can do this from inside the GUI.
If both your computers are Unix-like (Linux, Mac, etc.) you can also leave the GUI settings at default and use an ssh port forward to access it. For example,
$ ssh -L 9090:127.0.0.1:8384 user@othercomputer.example.com
will log you into othercomputer.example.com, and present the remote Syncthing GUI on http://localhost:9090 on your local computer.
If you only want to access the remote gui and don’t want the terminal session, use this example,
$ ssh -N -L 9090:127.0.0.1:8384 user@othercomputer.example.com
If only your remote computer is Unix-like, you can still access it with ssh from Windows.
Under Windows 10 (64 bit) you can use the same ssh command if you install the Windows Subsystem for Linux https://docs.microsoft.com/windows/wsl/install-win10.
Another Windows way to run ssh is to install gow (Gnu On Windows) https://github.com/bmatzelle/gow.
The easiest way to install gow is with the chocolatey https://chocolatey.org/ package manager.
