Yes, that's what i meant. A single ip could use all possible connections
for a userclass. Wich in fact is what happens with some of the more
aggressive ftp-clients. They often open 4, 6, 8 or even more connections
to get a file (or rather parts of it). This isn't meant to harm, but it
Imagine Joe Greedy would open 30 anon connections to get a single file,
and you have 30 connections as a limit in the anon userclass. Nobody
else in his class could get files. A per host limit should solve that.
Something like ,,Allow only 5 anon class connections from a single ip''.
