Dear Sir,
I am a master student of Asian Institute of Technology.
I do my thesis on a FreeBSD system. My thesis is in the topic
of computer network. I need to access the BPF device. I have
found that the information about it is very rarely available.
I can found a paper about BPF implementation in
"ftp://ftp.ee.lbl.gov" and a demo-program, tcpdump, which is
implement the BPF only in reading from it. However, I need to
write a complete IP packets-already have headers and options-
to a specified network interface without minding about the interface
topology. Someone in FreeBSD.org advised me to use the BPF.
Therefore, I need to know where I can get the information about
it. I can accept all source of information including text books.
Thank you for reading my mail. I am looking forward to
hearing from you soon.
Best regards,
Sunthiti mailto:stt@pluto.cpe.ku.ac.th
