Hi group, first of all: I am new to this group and hope to bring in some value later. At the moment I am such a beginner that I will probably of no use to anyone and only be asking stupid questions... I am running a little private linux server with kernel 2.4.21. It serves as a gameserver, webserver and mailserver, mainly. It also does the pppoe connect via a DSL modem to my provider and the NAT and forwarding for my local net (3 PCs). I would like to ensure perfect game server latency since its interactive (Quake 3 Arena), even while people are surfing my website or I am sending a large mail from within my local net. I read a little about QoS and are using a modified WonderShaper script. I am using 3 htb classes from which one is the interactive game server class - it gets 80% of the upload bandwidth guaranteed. tc -s class ls dev ppp0 shows me the classes and i see that traffic gets put into the right classes. So far - so good! But there are still bad lags when gaming and some other person surfs my web pages... :( Any Ideas? I can post my script if there is an interest in it... Thanks in advance, Tom. -- Word Perfect isn't, Excel doesn't, Works won't.
