Hi, I am studying the kernel source of FreeBSD. I like to know the flow of packets from NIC to different modules of Kernel and then to the user-level. I studied the code and identified some of the functions through which the kernel handles network packets..... But I want to check from where the control goes to that function....... So I decided to debug the kernel.... since I have only one machine I am not checking for kgdb.... I decided to work with DDB so compiled the kernel with option DDB and with debugging enabled (-g option). After installing the new kernel I rebooted the system and in the boot prompt I gave "-d" option to enter the debugging module..... My problem is that I can't provide any breakpoints with this method... It gives me error saying "symbol not found"..... Can anybody tell me where is the problem................ thanks Joseph stheg olloydson <stheg_olloydson@yahoo.com> wrote: it was written: >However, when it starts to install, it fails saying the filesystem is >full.

Any help would be appreciated. Thanks. Hello, This seems to be the nub of your problem. The message saying "the filesystem is full" means the partition is full, not the harddrive. Make sure the drive's geometry and that reported in disklabel agree. I think you should start over and use the instructions at http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/install-steps.html as a guide, particularly section 2.5.5. As to the problem with the router and intermittent failures to connect, that sounds like TCP/IP problem. The fact it seemingly goes away is very odd. Make sure you're not using an IP address already assigned to some other interface (and may as well that your subnet mask, hostname, and DNS address are correct, too). Double check that you're using a supported NIC. HTH, Stheg __________________________________ Do you Yahoo!? New and Improved Yahoo!
