To this, the networking code adds the net directory. It contains a number of files that show things like the kernel ARP tables, the state of TCP connections, and the routing tables. Most network administration tools get their information from these files.
The proc filesystem (or procfs as it is also known) is usually mounted on /proc at system boot time. The best method is to add the following line to /etc/fstab:
# procfs mont point: none /proc proc defaultsand execute ``mount /proc'' from your /etc/rc script.
The procfs is nowadays configured into most kernels by default. If the procfs is not in your kernel, you will get a message like ``mount: fs type procfs not supported by kernel''. You will then have to recompile the kernel and answer ``yes'' when asked for procfs support.
