Ok, after some times with /proc/sys/net/ipv4/tcp_ecn set to 0, it worked. Anyway I strongly suggest to modify this setting ASAP in procps. Moreover this is required only for kernel 2.4.5+ (why? Maybe it was turned on only after that release) And www.compaq.com (maybe) is not a minor site... And sometimes www.debian.org, too (due to BGP routing choices) I missed the previous thread. This bug rep should be merged with 110875 and others, maybe. -- Francesco P. Lovergine
