comment FreeBSD with nginx can't connect networks after running for a while
Yeah, that's might be good suggestion. Grep /var/log/messages for something like watchdog time out and other messages from your NICs' drivers

comment What permissions / ownership to set on PHP Sessions Folder when running FastCGI / PHP-FPM (as user “nobody”)?
1. Use same user:group for nginx and php-fpm (via either nginx.conf or php-fpm.conf), so you can keep this directory 700. 2. Use chown -R nginx:nobody /var/lib/php/session && chmod -R 770 /var/lib/php/session so i think both nginx and php-fpm can use it

There is always something that you can't install from packages, so you need to use ports instead.

not rc.conf, but pf.conf, you also need kldload pf and pfctl -e for nat to start working. Also read FreeBSD hanbook about handling pf firewall

Because for 7.2-release there is only isc-dhcp3-devel is accessible via packages that is in unstable branch at that time. And stable release 3.1.2p1_1 can only be accessible via ports.

You can also use something like Dynamips or GUI utility like GNS3 ( gns3.net ) to emulate cisco devices, using IOSes from ISOHunt.com, and connect virtual cisco network to the real one.

comment how to install sphinx plugin for MySQL on windows?
Not exactly. Sphinxsearch can be used without SphinxSE plugin installed: you can run sphinxsearch on different port and set it to advertise itself like mysql server, so any software that is compatible with mysql can use it and run simple SQL queries.
