Hi All, I've mentioned this prblem earlier. It is about large file transfer not taking place in fedora core 2 kernel 2.6.5-1.358. When I am getting packets into userspace and doing some processing. http://lists.netfilter.org/pipermail/netfilter/2004-September/056036.html I was doing "ip route change 10.6/16 mtu 1000 dev wlan0" If I lock the mtu value then it just works fine. Does it mean that this kernel is not considering my request to set the mtu to 1000?because..I read that.. "If the modifier lock is not used, the MTU may be updated by the kernel due to Path MTU Discovery. If the modifier lock is used, no path MTU discovery will be tried, all packets will be sent without the DF bit in IPv4 case or fragmented to MTU for IPv6" If this is so what is the role of "/proc/sys/net/ipv4/ip_no_pmtu_disc " , which still shows the value 0. Also given the fact that transfer happens on 2.4.18-3 kernel with same pmtu setting. Could anyone pleasse explain me the fundaes behind this? thanks Nikhil __________________________________ Do you Yahoo!? New and Improved Yahoo!
