>Release: FreeBSD 2.2.2-RELEASE i386
>Environment:
FreeBSD, AFAIK all releases
>Description:
ac(8) (a connect time accounting utility) reports wrong times,
often 0.0
Reason: The program doesn't account for logins on pseudo-ttys (ptys)
from local, i.e. without a host-entry in wtmp.
The code to decide what's a pty is not corrected for
FreeBSD's pty naming conventions.
>How-To-Repeat:
>Fix:
I supply a patch which adds a '-l' option to account local logins on
ptys and makes ac(8) aware of FreeBSD pty names.
