Ok - after talking to my net admin chappy - he has another question, and I quote : "it would be better to ask of the best way to set up an ethernet network to optimise your chances of capturing information whilst maintaining high performance switched networks" and he said to ignore any smart arses that suggested going back to using hubs :) Well ?
Well, I can't say 'Use a Hub' so... I'll say use a tap.
Anyone got any good advice on this... On the face of it - turning on the port mirroring on the switch sounds like it will do the job - but will anything suffer noticeably after we've done it? (Apart from the snort box, we're expecting that!)
OK, serious answer here (Yeah, I know, it's not like me... :) : Depending on the switch processor and backplane is the main factor in losing network performance. If you switch is a billy-bad-ass 6509, for example, and you only have 5mb of traffic, then you'll be fine. If it's a 2924 and you're pushing 70mbs, you might have issues. If you want to skip the switch, you could use a Shomiti Tap for it. Shomiti just got aquired or name changed to Finisar Systems... You can find them here: http://www.finisar-systems.com/products/taps_and_splitters.html The cost is a bit high, but cheaper than a new switch if that's not an option. Now, see why a hub is just simpler? ;-) ----- Erek Adams Nifty-Type-Guy TheAdamsFamily.Net _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: https://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users
