Write on proc filesystem
|
|

Hi! I need to write on proc filesystem to enable a personal version of
tcp debug on fly. Do you know where I can find some documentation about
that?
Thanks.

in kernel source /net/ipv4/ here you find tcp stack.
But i think you have need to recompile all kernel ...

You can write on the proc filesystem. Many configuration options are
implimented just like that
echo 1>/proc/sys/net/ipv4/ip_forward
is how to switch on ip forwarding.
But since it is just a look into the kernel, the kernel option must allow
writing to it. |

Tanks, I've made a mistake, I need to "read" (Kernel side) on proc
filesystem. I would modify the tcp code to insert a little part which
show the debug option to user.
Thanks.
