Hi, I am trying to learn about FreeBSD kernel development. I have set up two machines with -CURRENT, and have connected them via null modem cable. I have followed the instructions in the Developer's Handbook, "On-Line Kernel Debugging Using Remote GDB" ( http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/x9972.html ) and can successfully debug remotely using gdb.
What I am interested in doing is learning more about how the FreeBSD networking system works. What I would like to do is, from machine A, ping machine B. On machine A, I would like to set a breakpoint in the network device driver when the upper layers in the networking stack calls the device driver to transmit data. I am interested in debugging the following drivers: - fatm , from Harti Brandt's Netgraph ATM subsystem: http://www.fokus.fhg.de/research/cc/cats/employees/hartmut.brandt/ngatm/ - fxp, the Intel EtherExpress Pro driver Can someone give me some hints as to where a good place to set the breakpoints would be, or pointers to further information about FreeBSD networking? Thanks. -- Craig Rodrigues http://www.gis.net/~craigr [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
