Emm, no, has to be '0'. If '1', it _ignores_ icmp echo's.

... because everything under /proc are not regular files, but knobs,
buttons and control dials (so to speak...) that control or monitor how
your system is operating. They are presented to you in what appears as a
filesystem with more or less regular files in it.

If you have the rights, you can read and write these files as usual. But
using an editor is not such a good idea, because editors do a lot more
with files than just reading and writing (seeking, copying into temp
buffers, etc...).
