Hello, I try to set up my Linux 2.4.x system to respond by "ICMP Destination Unreachable message" subtype 4 ("fragmentation needed and DF set") in order to support the Path MTU Discovery (RFC 1191) as a router. There is any /proc/xxx parameter to do this? Thanks Mugur _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
