Date: Sat, 13 Jan 1996 16:18:51 GMT Organization: Netcom Lines: 26 Message-ID: <4d8m2e$ao@ixnews2.ix.netcom.com> NNTP-Posting-Host: ix-gra1-07.ix.netcom.com X-NETCOM-Date: Sat Jan 13 8:19:26 AM PST 1996 X-Newsreader: Forte Agent .99b.112 I've seen many references to recompilng the kernel with the "BPF" option. For give my ignorance but is that done by simply adding a line like?: options BPF #Berkeley Packet Filter Assuming the above is correct, I added the option to my kernel and recompiled. Afterr I reboot the machine and try "tcpdump" it gives me the message "/dev/bpf0: No such file or directory". So....I tried doing a "MAKEDEV /dev/bpf0" which worked, but only resulted in the error "/dev/bpf0: device not configured" when I tried "tcpdump again". Any ideas on how to get this working? One other thing, why is it that I cannot execute an executable that is not located in my path....I would think as long as I am in the directory with the executable is located that it would work? For example, in order to run MAKEDEV (located in /dev) I had to change my path to include /dev. I'm sure it's something I've set wrong, but.... Thanks to all that answer!!
