I =B4m using NeTraMet Vers. 4.3 on an FreeBSD 4.2 System (i386) with libpcap-04. NeTraMet uses libpcap for monitoring and get the packets on the LAN. It could be that ethernet packets were dropped by the kernel and NeTraMet, which happens when i capture some minutes of the LAN traffic with tcpdump 3.5 . Tcpdump gives an information about how many packets were filtered and how many packet were dropped by the kernel. NeTraMet doesn=B4t do this. How could i be on the secure site, that NeTraMet get all packets. If NeTraMet droppes the packets like tcpdump what can I do. In the newsforum from NeTraMet someone says to boost the bpf buffer but he didn=B4t know how. (the counter it is referring to in /sys/net/bpf.c in the kernel.) seems to be=20 # define BPF_BUFSIZE 4096 so i have to increase this. And there for I have to recompile the c-source code, but which of the source and how. Where I have to put the binary?? Could you help me or give some hints??=20 Thanks in advance Ren=E9 Heimes To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
