Just last week I tried a little program called "ifstatus" on
Solaris. The program is designed to run from cron so that only if
an interface is in promiscuous mode, it will print out a warning
message. Here is a snippet from its manual page:
DESCRIPTION
Ifstatus checks all network interfaces on the system, and
reports any that are in debug or promiscuous mode, which may
be a sign of unauthorized access to the system.
You can get it from
ftp://coast.cs.purdue.edu /pub/tools/unix/ifstatus/
When you compile it for Linux you need to edit Makefile like this:

That is, change SUNOS55 to BSD and comment out any libraries.
