nmap on a scan server

Hello, we are thinking about setting up a public self scan service. Of cause we want to do the scans with nmap. We are planning to start the scans via ssh on a dedicated machine to seperate this from the web server. As we are expecting a huge load (especially in the peaks) we need to make this as fast as possible. We are talking about hundreds if not thousands of parallel scan requests. Does anybody has experience with this kind of load? Any kind of information is appreciated, especially: Is it possible, to run many nmap instances in parallel? Are there known limits? Anybody with experience on running 100 nmap instances on one machine? Do I have to expect weird results because of incoming packets not delivered to the right nmap instance? What are good timing options for a TCP Syn scan on port 1-1024, that should be reliable *and* fast? Is it making sense to start nmap directly via ssh or is it better, to have a perl script as a wrapper on the scan machine? bye, ju PS: Accidently I sent this message first to nmap-hackers, because I subscribed to this list ages ago and didn't realize, that it became moderated in the meantime: So if the moderator is reading this: please ignore my first mail ;-) -- Juergen Schmidt Leitender Redakteur/senior editor c't magazin Heise Zeitschriften Verlag, Helstorferstr. 7, D-30625 Hannover Tel. +49 511 5352 300 FAX +49 511 5352 417 EMail ju () ct heise de --------------------------------------------------------------------- For help using this (nmap-dev) mailing list, send a blank email to nmap-dev-help () insecure org .
