Can one of the admins verify that this patch is reasonable to test? (reply "ok to test", or if you trust the user, reply "add to whitelist")

I signed it!

Thanks! The range is actually supposed to be 30000 - 32767, although I had an off-by-one error originally (as you spotted). I fixed my mistake, so the default should now be 30000-32767.

[pnovotnak]

I was wondering about that :)

Updated.

LGTM

[mikedanese]

@pnovotnak can you squash your commits into one?

[pnovotnak]

Squashed.

[mikedanese]

@pnovotnak this is LGTM but I was unable to look up the CLA on our internal system. I looked up your github username, the email on the commit, and the email on your github profile. Are you sure you signed it? Was it a corporate cla? @googlebot is angry.

[mikedanese]

@googlebot check again!

[pnovotnak]

I just submitted another CLA for my personal email address and made sure my github username was attached.

The one submitted via my work address' email is: peter@cyrusbio [dot] com
