i know how it would be done. just thought if i could find the code/tool it could save me alot of time. Simon Richter wrote:
Hi, Q Beukes wrote:I am looking for linux utility that checks if a specified machine's network device is in promiscious mode or not.Technically, promiscuous mode only affects packet reception, so it is pretty difficult to detect; however most packet sniffers will not hide the packets that would have been filtered normally from the kernel, so the kernel should react to e.g. a ping or SYN packet that has the correct destination IP address for that host, but would normally be filtered by the MAC (e.g. with a different destination MAC address). I don't have a readymade utility for that (I'd code it if need arises, but the days of Cheapernet are gone), but you can test from the shell by creating a static ARP entry using the arp(8) tool and then pinging the IP.
