sysctl variables and useful OID lists

I see people keep asking for "full lists" of sysctl variables on various forums, so i did a "sysctl -a -d > blah.txt" on 2 systems i have access to and here are the text files. note that these will vary from system to system.

sysctl -a -d on a FreeBSD 7.0-RELEASE-p11

sysctl -a -d on a Linux 2.6.18-128.1.1.el5.028stab062.3

This made me think of the neat OIDs to be used with SNMP(simple network management protocol) you can use snmpwalk like this

snmpwalk -v [snmp_version] -c [community] [ip_address][object id]

Here is a list of OIDs found on another site
