Quite the opposite is true actually. Putting the nic in promisc mode tells it to listen for all packets on the network. Not putting the nic into promisc mode tells it to just listen for packets meant for that nic's IP address specifically. > Unfortunately, the Linux default is to come up in > promiscuous mode when going onto the internet especially so with Debian. Wrong again. The gnu/linux default is to *not* bring up the interfaces in promisc mode on startup. I've installed slackware, and debian on a number of systems a number of times, and even installed gentoo once. At no time did these installs result in bringing up the nics in promisc mode at startup. If what you're saying is actually what you've read, then I'd like to have a look at the documents in question, so that I can either correct my misinformation, or fire off an email to the authors responsible for spreading such misinformation. Otherwise, I must conclude that you're misinterpreting what you've read, in which case, it's no surprise to me at all that you're dealing with packet sniffers and successful cracking attempts on your system(s).
