You can compile a debug kernel on the debugging machine and then ftp the kernel to the target machine. If the / on the target machine is not large enough, you can let the debug kernel overwrite the existing kernel with command install. Then you can use remote debugging. -Zhihui To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
