I've run it (quick tests ONLY -- we use NCSA 1.5, which I'm running now on our 2.0.5R machine) with few problems (actually, fewer problems w/ Apache than NCSA). The only reason I'm still running NCSA is due to minor incompatibilities between them (and we're kinda planning on switching everything all at once). One thing that I read somewhere (on this list, perhaps) is that setting : DNSMode Minimum in your httpd.conf will help. What it does is stop reverse DNS lookups on IP to find the hosts that are hitting you. So, your access_log only has IPs, which may be irritating if you're trying to do analysis. This can be overcome with a little perl script. I dunno if I can distribute my version to do the lookups and rewrite the access_log (this is at work), but it's really easy, so I'll: (a) describe the algorithm briefly and (b) offer to rewrite it at home (email bkogawa@netvoyage.net to remind me). The basic algorithm: for each line in the access_log: strip out the IP look it up. If you can find it, rewrite the line with the name. :) One trick is that you can use is an associative array to cache the lookups. This can lower it to one ns request per IP, at the cost of memory. This is how I was doing it when I was testing my software, but I suspect performance could get really horrible if the logs were too big and memory ran out. bryan > > Doug White | University of Oregon > Internet: dwhite@resnet.uoregon.edu | Residence Networking Assistant > http://gladstone.uoregon.edu/~dwhite | Computer Science Major > > Bryan K.
