Interesting, I didn't know that, I did the pcap from my Linux router box, steam it's self was running on Windows. Judging by the use of hrping earlier I assume Dendari is also running windows. I am 99.9% booted into Linux on my desktop - but it's pure 64bit LFS and I am far too lazy to build a multilib LFS just for steam :-)
