I seem to have something configured on my FC2 machine that is blocking some web sites, and I'm looking for pointers on how to figure it out. Certain websites hang when I try to access them, and I believe it is because packets are being blocked somehow. However, I'm not sure what needs to be unblocked. In my /var/log/messages file, when I access one of these web sites, I see lines like the following: Sep 12 10:35:52 piper kernel: IN=eth0 OUT= MAC=00:a0:cc:74:17:a1:00:d0:79:28:4c:38:08:00 SRC=72.246.49.34 DST=198.144.206.7 LEN=60 TOS=0x00 PREC=0x00 TTL=58 ID=0 DF PROTO=TCP SPT=80 DPT=34385 WINDOW=5792 RES=0x00 ACK SYN URGP=0 Sep 12 10:36:37 piper last message repeated 7 times Can someone give me some debugging suggestions for this? Is it an iptables thing? Is there a networking parameter that I've set wrong? Thanks, -Roger
