next in thread | raw e-mail | index | archive | help
I have added some global varables in the /usr/src/sys/netinet/ip_input.c
file. I use those for some IP layer hacking and have currently hardcoded
them (just integers) and have to recompile and reboot every time I
change the value.
How can I change the values in a running system? Is adding a new sytem
call to set them the only way? (if that IS a way :-))
If so, how does one go about creating a new system call for that? Is
assembly prog. neccessary?
any help will be greatly appreciated.
thanks
Sumit
