This code is a port to recent FreeBSD of Darrell Anderson's network crashdump support, which was done in the 4.x days. I can't find a current website with the original versions but archive.org has a cache of course: http://web.archive.org/web/20041204223729/http://www.cs.duke.edu/~anderson/freebsd/netdump/ Quoting from the old readme: Netdump provides FreeBSD kernel crash dumping over the network. Netdump is a FreeBSD kernel module client and user-level server. A normal kernel crash writes a raw dump of memory to a dedicated partition (usually the swap partition) using a low-level disk routine, and then copies that raw dump into a file (via savecore) during the following boot process. Netdump replaces the standard dump routine. During a crash, a netdump client broadcasts to locate a netdump server, then sends the dump as UDP/IP packets (with retransmission after loss). The netdump server creates a dump file suitable for gdb. If netdump fails (for example, no netdump server is located), a normal disk dump is performed. There is cleanup work to be done still, but we plan to have this in shape for 9.0. -Ed _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
