As far as I know all public exploits for HL1 engine were fixed by Valve, so you don't need any additional protection if you're using the latest binaries.
Initially only NOSTEAM servers were vulnerable to CSDOS and Born to be Pig exploits, so Valve did nothing about them. This is why Anti CSDoS and HLShield were so popular. But Valve fixed the bugs when the exploits were used to attack legit servers (also they fixed other important exploits, like the ones using bugs in SV_ParseVoiceData and SV_ParseCvarValue2 functions). Note that the HL1 engine is still vulnerable to simple flood attacks. Also probably the servers are still vulnerable if they allow users to download files directly from server, so you should use only fast download for any custom resources (and block the local downloads). This is probably the latest update: http://www.mail-archive.com/[email protected]/msg63861.html Some are still waiting for Valve to release the client side update :)) -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Marcel Sent: Saturday, December 31, 2011 2:21 PM To: Half-Life dedicated Linux server mailing list Subject: [hlds_linux] Anti CS DOS Hi, It seems that I've missed a thing. Can anybody tell me what all of this Anti CSDoS and HLShield is about? Is it really needed? I'm a bit afraid of loading a library from a .ro website where I don't have the source code ;) Cheers Marcel _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: https://list.valvesoftware.com/cgi-bin/mailman/listinfo/hlds_linux _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: https://list.valvesoftware.com/cgi-bin/mailman/listinfo/hlds_linux
