Description ryan.rempel 2000-11-01 16:40:01 UTC 
The freeBSD sysctl (8) command has been updated to display sysctl values as unsigned ints when the oid format is "IU". However, when using sysctl (8) to set sysctl values, strtol is used on the input, even for oids with format "IU". This means that values higher than 0x7FFFFFFF are clamped.

Fix: Here is a patch (I wrote) to sysctl (8) that fixes the problem.
How-To-Repeat: Use sysctl to set an unsigned int value higher than 0x7FFFFFFF. For instance:

sysctl -w kern.hostid=3456789012
