. "KGDB"@en . . . "KGDB is a debugger for the Linux kernel and the kernels of NetBSD and FreeBSD. It requires two machines that are connected via a serial connection. The serial connection may either be an RS-232 interface using a null modem cable, or via the UDP/IP networking protocol (KGDB over Ethernet, KGDBoE). The target machine (the one being debugged) runs the patched kernel and the other (host) machine runs gdb."@en . .
