There is an linux server with 2.4.24 kernel and pinging from him to internet (or from lan) ping randomly jumps up: 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq87 ttlY time0.0 ms 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq88 ttlY time2.6 ms 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq89 ttlY time4.9 ms 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq90 ttlY time8 ms 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq91 ttlY time@7 ms 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq92 ttlY time@7 ms 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq93 ttlY timeC0 ms 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq94 ttlY time0.9 ms 64 bytes from fortas.ktu.lt (193.219.160.131): icmp_seq95 ttlY time1.6 ms Internet line isn't loaded up, server load fine. QOS isn't used, qdiscs default. I don't realize what the problem is and even how to debug it. Sysctl config: net/ipv4/ip_forward = 1 net/ipv4/icmp_ignore_bogus_error_responses = 1 net/ipv4/icmp_echo_ignore_broadcasts = 1 net/ipv4/tcp_syncookies = 1 net/ipv4/tcp_timestamps = 0 net/ipv4/tcp_window_scaling = 0 net/ipv4/tcp_sack = 0 net/ipv4/tcp_fin_timeout = 30 net/ipv4/tcp_keepalive_time = 1800 net/ipv4/tcp_low_latency = 1 Thanks for any thoughts. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
