Reply-ul vine imediat de la interfata, se pare ca e intarziata trimiterea de pachete: 16:37:38.406200 IP 127.0.0.1 > 127.0.0.1: ICMP echo request, id 50215, seq 0, length 64 16:37:38.406232 IP 127.0.0.1 > 127.0.0.1: ICMP echo reply, id 50215, seq 0, length 64 16:37:39.454648 IP 127.0.0.1 > 127.0.0.1: ICMP echo request, id 50215, seq 0, length 64 16:37:39.454668 IP 127.0.0.1 > 127.0.0.1: ICMP echo reply, id 50215, seq 0, length 64 16:37:40.507563 IP 127.0.0.1 > 127.0.0.1: ICMP echo request, id 50215, seq 0, length 64 16:37:40.507582 IP 127.0.0.1 > 127.0.0.1: ICMP echo reply, id 50215, seq 0, length 64 Fping merge ok fara delay-uri, asa ca am dedus ca e o problema de utilitar (ping). Am downloadat si compilat: http://www.skbuff.net/iputils/iputils-s20071127.tar.bz2 si am facut teste, dar am aceleasi rezultate. Modificari de packetsize si fragmentare nu schimba situatia. -- Catalin Bucur mailto:c...@geniusnet.ro NOC @ Genius Network SRL - Galati - Romania _______________________________________________ RLUG mailing list RLUG@lists.lug.ro http://lists.lug.ro/mailman/listinfo/rlug
