Pflogsumm README
There's not much to installing pflogsumm, so it's all manual.
1. Unpack the distribution (if you're reading this, you've already
gotten that far)
2. Copy or move pflogsumm.pl to some directory from which you'll
want to execute it. Maybe rename it to just "pflogsumm."
Watch the ownerships and permissions. Make sure it's executable.
E.g.:
cp pflogsumm.pl /usr/local/bin/pflogsumm
chown bin:bin /usr/local/bin/pflogsumm
chmod 755 /usr/local/bin/pflogsumm
3. If there's a manual page available (pflogsumm.1), copy that to
/usr/local/man/man1 or wherever you stash local manpages. Make
sure it's world-readable.
E.g.:
cp pflogsumm.1 /usr/local/man/man1/pflogsumm.1
chown bin:bin /usr/local/man/man1/pflogsumm.1
chmod 644 /usr/local/man/man1/pflogsumm.1
4. Read the man page (or the top of pflogsumm itself) for usage.
5. Check the FAQ (pflogsumm-faq.txt)
6. Configure your cron jobs if you're going to run pflogsumm on an
automatic, scheduled basis. There are tips in the manpage and
the FAQ.
That's about it.
As the manpage and FAQ both note: pflogsumm requires the Date::Calc
Perl module if you want to use --smtpd_stats.
