How-to repeat it: Take freebsd-4.5 or 4.4 with ipfilter v3.4.20 and set up some ipfilter rules. Basic example: ipf.rules: pass in quick on lo0 pass out quick proto tcp all flags S keep state keep frags pass out quick proto udp all keep state ipnat.rules: map fxp0 0/0 -> 0/32 proxy port ftp ftp/tcp Then try from the box: ftp pann.starnet.ee Your machine freezes. I dont know what is so special with this ftp site, i looked at tcpdump logs and saw nothing abnormal. Btw, it may be wise to check that you dont have any other ipfilter wall in path to that ftp server. -- Markko To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
