Hi
Now I would like to debug kernel for analizing IP module
Noe I use gdb (I don't want using 'printk')
But a problem was happened.
following:
----------------
[lucky:root:/root 1 ] gdb /usr/src/linux/vmlinux /proc/kcore
GNU gdb 4.17

This GDB was configured as "i386-redhat-linux"...
#0 0x0 in ?? ()
(gdb) run
Starting program: /usr/src/linux/vmlinux
ulimit: Command not found.
warning: shared library handler failed to enable breakpoint
Program received signal SIGSEGV, Segmentation fault.
0x100006 in startup_32 ()
(gdb)
------------------
and program was stoped
Do anyone know how to debug IP module as using gdb ?
Please, I would like to know that technique.
Thanks,
Seunghan.
