Half-Life (old): RCON Broken

[Xylemon]

Using RCON on Half-Life WON2 (old) servers just gives me the message "hallenge." However, it seems that Steam Half-Life servers are giving proper messages.

Hmm, too bad, I do not have any access to this kind of server to check that! I don't know how to reproduce myself. :confused:

[Xylemon]

I host a few. Perhaps I could run a temporary one and email you the rcon password for it?

[illwieckz]

It could be very nice! I've not many time right now, but perhaps in july/august I will have more free time, I would keep you informed. :wink:

[Xylemon]

Alright, just email me xylem2020[at]gmail.com or leave another comment here!

Do you know any other open source rcon tool for old Half Life servers that I can read some source code to see how it works?

[Xylemon]

Sadly the only tool I can think of is QStat, however https://github.com/alliedmodders/amxmodx is a great plugin for HL servers that lets you control rcon. Might be worth looking at.

[illwieckz]

Can you try multircon (web page, zip sources) to check if his claimed support of HL server is true ?

[Xylemon]

It did work for me with my WON2 servers.

[illwieckz]

Nice, so we have a reference implementation to compare :-)

[illwieckz]

What if here: src/rcon.c#L168

You do that:

-       char* mustresponse = "\377\377\377\377challenge rcon ";
+       char* mustresponse = "\377\377\377\377challenge rcon\n";

?

[Xylemon]

Same thing. Nothing different appears.
