WARNING:
Please do not install the bmon executable as SUID root. This
software package was written with portability and configurability
in mind and will never fulfill the requirements to be installed
as SUID root executable.
If you do please be aware that every user will be able to run
arbitary commands as root via the key bind interface or by
providing a malicious netstat binary.
In fact there is no reason to do so, all supported input modules
will work fine without superuser privileges. There is probably a
good reason if your operating system requires special privileges
which is that a normal user is not supposed to read the statistics
which should not be worked around using the SUID bit.
Thanks.
