Re: [hlds_linux] server info query.
I think it's because you need these to be separate if statements. The
way you have written it, the if statements are nested. Try making them
all stand-alone instead of nesting most of them under the if($EDF -band
0x80).

Still not to sure about the EDF of 145. On some servers I see 10 bytes after
the EDF, two for the gameport and eight for the steamID. On other servers
there are only two bytes after the EDF, the gameport. The script displays
the correct game port, not sure why that is included since I had to send the
info_query to that port. Guess I should display the ABS of the server steam
ID. The 2nd AppID displays ok. except on my lan test server. It does not
send the byte.

Re: [hlds_linux] server info query.
Removed the nested if(s). The output is the same. I'm happy. To make it easier to see the raw data being received I Reduced the size of the receive buffer from 1400 bytes to 144 bytes. Looking at the sample output I see that the first three servers (sc4.6 test servers) reply to the info query with all the expected data. The next server (Raspberry's) sends an EDF of 144 rather than 145 like all the other servers? It does not send the 2nd AppID. And the last three do not send all of the extended data. They only send the server game port after the EDF. The script is configured to use a UDP slow link delay allowing ten seconds for a reply. A server sending an EDF of 144/145 there are usually three or four pieces of information in the extended data. The EDF does not change when the all the data is not sent. I already know the gameport (sent the info_query to it), Have no Idea what to do with the SteamID and I already have the AppID. Tested with a dummy-ed up receive buffer containing an EDF of 245 to check the other two items: ( EDF -band 0x40 ) and ( EDF -band 0x20 ) The extended data received varies from server to server and it is probably of little value, except as an exercise in understanding valve's documentation.

Re: [hlds_linux] server info query.
You need to evaluate a bitwise AND of the EDF value and the various values
defined in the A2S_INFO specification. I haven't done this in PowerShell, but
a quick Google search for bitwise operations makes me think that you need to
use -band (bitwise AND) instead of -and, like so:
if($EDF -band 0x80)
{
# Server's game port is included
}
if($EDF -band 0x10)
{
# Server's SteamID is included
}
if($EDF -band 0x40)
{
# Spectator port and server name are included
}
if($EDF -band 0x20)
{
# Game tag data is included
}
Again, I haven't actually tried this, but I think the -band may be what you're
looking for.

hey, I hacked out a script to monitor local or remote servers. it is kinda simple it sends a ping gets the reply then sends an info query and gets the reply. If I can figure out the rcon stuff I will add that. It loops through the received UDP packet (a 1400 byte array) to get the four variable length strings (servername, mapname, directory, description) then searches for an appid that is equal to 70. After the appid is found it increments through the byte array one byte at a time to get and format the rest of the data. ref: [URL] http://developer.valvesoftware.com/wiki/Server_queries#Source_servers_2[/URL] Having a little trouble with the extended data flag.
