good low level protocols for minetest

[niwla23]

I am planning to write a system to sync join messages across server, i heard sockets lock up the thread, what technique, protocol would you reccoemnend me?

So what I want to do is this:
When a Player joins Server1, on Server2 and Server3 should be shown <player> joined Server1
When a Player joins Server2, on Server1 and Server3 should be shown <player> joined Server1
and so on
Or is there maybe already a mod for this?

one idea:

watch ( with a script ) on all servers the debug.txt
if ther is a new line like "xxx joins server" send a string to all other servers
recive the string on all other servers with "external_cmd" mod > viewtopic.php?t=3924

Hm yes that would be possible, but I would just use the lua events.
Do you know any simmilar mods to external_cmd? It looks a little bit "hacky" for me

Some servers manage to achieve that already by sharing one channel on an irc server. Messages ingame and on irc are forwarded.
