first of all i wouldn't connect a sprite to the internet... those boxes belong on your internal network. if you need to access it from outside then use
vpn. i've used it and it works fine.
Concurrent with EVERY attempt to access the DS2, a port scan was initiated from the DS2's address at the visiting address, and this can be reproduced at will. For scan logs, see original email to vendor below. (Public IPs modified.)
i think that your IDS is confused and really what happens is that when the client software connects to the sprite it opens a bunch of ports (21 prehaps) and then the digital sprite connects back to your client on those ports... it's not really much of a port scan... maybe you should turn down the sensitivity of your IDS's portscan detector. btw those digital sprites rock.. they're multiple camera multiplexors and hard drive recorders with time lapse recording built in. and eventdetection. all in a nice little 1u rack mount box, but yeah keep it off the
internet. -eek .... A. David Bullock eecue : programmer / designer / admin / human http://eecue.com/ anything is possible _______________________________________________ Full-Disclosure - We believe in it. Charter: http://lists.netsys.com/full-disclosure-charter.html
