libpcap doesn't differentiate between the various logical interfaces, it's at the level of the physical one (try tcpdump -i eth0:0 -c 5 for example). Since libpcap doesn't differentiate, ntop can't.
Since it will see the traffic, ntop adds any virtual addresses automatically. So if you specify -i eth0, you get eth0:0 ...eth0:7. -----Burton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Cetera, Tony Sent: Wednesday, October 29, 2003 1:15 PM To: '[EMAIL PROTECTED]' Subject: [Ntop] Ntop, netflow virtual interface I'm running ntop 2.2c on Redhat 9 and have a question about the configuration of the virtual netflow interface. I have configured a virtual interface eth0:1 on the subnet I want to monitor flows to/from. I'm assuming this is the correct network for that interface. I then specified the IP address and netmask of that interface on the Netflow statistics config page. I restarted netflow and specified eth0 and eth0:1 with the -i parameter. The problem occurs when I attempt to "switch NIC". The only option available is eth0 and eth0:1 is not listed. Have I configured the virtual interface incorrectly? Thank you.
