Guys I am trying to remotely debug my FreeBSD machine using gdb. For this I have complied the GENERIC kernel with following debugging options:
Then I have complied my kernel using following commands
Then i connected the two machines with the same kernel named DBGKERN using DB09 female-female cable(nullmodem). Now when i run the debugee machine using boot -g options the system response is very slow and it gets stuck while displaying dmesg output. When I try from inside the OS by running KGDB on debugger machine and enter command
It enters into a non responsive db session while the debugger machine shows an error "Malformed response to offset query, timeout"
Please help me soon. Thank you
