In this post I’m going to talk about some old text editors you probably never heard of, …
I’m doing 99% of my coding in a “big” machine instead of my laptop. I do that by SSH’ing into it, hopefully into a
tmux session, and coding on Neovim.
After digging some source and testing a little, I found out that Discord’s bind itself to a socket in one of the following places:
[[\\.\pipe\]]discord-ipc-0on Windows, whatever the hell that means;
So, my idea was: what if I do a remote port forwarding of that socket?
I tested it with:
ssh -v -R /var/run/discord-ipc-0:$TMPDIR/discord-ipc-0 myhost
And it worked!
But I don’t want to type all that every time… so… let’s make it better!
First, we need to add some settings to our
~/.ssh/config file: mainly,
RemoteForward and a
Match host instruction.
Here’s the relevant parts from mine:
Match host myhost exec "ln -sf $TMPDIR/discord-ipc-0 /tmp/discord-ipc-0" Host myhost RemoteForward /run/user/1000/discord-ipc-0 /tmp/discord-ipc-0
We need the
Match host with the
exec linking the file because, as it seems, we can’t use environment variables in the
Then, we need the
RemoteForward, target being the server’s
$XDG_RUNTIME_DIR/discord-ipc-0 file and source being our linked
And that’s pretty much it here.
On our server, we need to enable
StreamLocalBindUnlink, otherwise, the first time you SSH into it it’ll work, but the next times it won’t, as the socket would be dangling from the previous one.
StreamLocalBindUnlink tells SSH to remove the socket if the exists, before trying to bind it again.
You can enable it with something like:
echo "StreamLocalBindUnlink yes" | sudo tee -a /etc/ssh/sshd_config.d/discord.conf sudo service sshd restart
And that’s it!
You should now be able to SSH into your host and test the connection with
ssh -v myhost socat -u OPEN:/dev/null UNIX-CONNECT:/run/user/1000/discord-ipc-0
You shouldn’t get any errors, and SSH will print out some logs as we’re connecting with
-v (verbose - not required from now on).
With the presence plugin install should set your rich presence status to “Playing a game: Neovim”:
And that’s pretty much it!
You should be able to disconnect/reconnect and always get a valid socket, so it should “just work”.
