[hlds_linux] Server protect attacks

[Emanuel]

Hi folks, I need tips to protect my server Counter Strike 1.6 (HL-BETA) 
attack (UDP flood), as I have read this can be done using iptables rules.


To block momentarily use the following iptables rule:

iptables -I INPUT -p udp -m udp -m string --algo bm --hex-string 
|56| -j DROP


Can anyone guide me or help me?

Re: [hlds_linux] Half-Life 1 dedicated server update released

[Fletcher Dunn]

This change is going live today.  Direct UDP heartbeats from Half-Life 1 
servers will no longer be supported.  You must update your server to get the 
latest Steam binaries, which support the new protocol.

Subject: [hlds_linux] Half-Life 1 dedicated server update released

We have released an update to Half-Life 1 dedicated servers. This update fixes 
a potential vulnerability in the challenge/response protocol uses for out of 
band queries (in particular A2S_RULES and A2S_PLAYERS responses). The update 
also fixes sprays not functioning correctly when new users join a server.

Also as a reminder, we will be disabling the older heartbeating protocol later 
this week so you need to update to be listed on the master server. This change 
only effect the server side, any clients (i.e server list generators or 
management tools) will be unaffected by this change.

Hello, Alfred.

This is not fixed in stable version so far. This is so sad.
