>Hi, Are you sure that this machine wasn't compromised ???

this line made me wonder about what the correct output of ifconfig should 
be.  I assume that if I am not listening on the port, the PROMISC entry 
should not be reported in ifconfig.  I should only see PROMISC if I am 
running tcpdump, ethereal or some other program that listens on the 
ethernet port.

On eth0, I see PROMISC all the time.  On eth1 & eth2, I only see it when I 
am running tcpdump.  I have ipchains denying all traffic on the link that 
is directly connected to the net.  This is run before the interfaces are 
configured.  Despite ipchains, all services (telnet, ftp, apache etc) are 
turned off coz I don't use them.  I run apt-get update/upgrade daily to 
keep up with security updates from security.debian.org.  The kernel is 2.2.17

Is there any reason for eth0 to be showing PROMISC all the time or is this 
a sign that the system has some how been compromised and someone/something 
is capturing all internet traffic?  Everything looks fine on the 
system.  Hopefully I am being unnecessarily paranoid.
