I'm running 3.7-RELEASE with all patches on x86 hardware. I've tested
the bandwidth on them machine, and can easily handle 200-300Mbps. I/O is
decent too (this is an IBM x335 [dmesg below]). What *really* is nearly
impossible is running nessus and nmap on this host. Even using the ports, a
single nmap scan will take more than 4 hours. The network is 100
full-duplex, and I've even testing setting the bge(4) cards to half-duplex
at 100Mbps. Any machine I've ever run nessus/nmap on with OpenBSD as the
underlying operating platform has had this problem.
For those of us running your vulnerability scanners on OpenBSD, do you have
any tricks to fix these issues? I know they're not the best-coded
applications, but I'm stuck running them.
Any thoughts are appreciated. I've tried with pf enabled and disabled, no
major difference in speed. I have a GENERIC.MP kernel with all the current
patches applied.
Thanks.
