Installation

Download Sentry

bash || sh
export SENTRY_URL=https://raw.githubusercontent.com/msimerson/sentry/master/sentry.pl
curl -O $SENTRY_URL || wget $SENTRY_URL || fetch $SENTRY_URL

Run it:

perl sentry.pl

Running sentry the first time will:

• create the sentry database
• install the perl script
• prompt you to edit /etc/hosts.allow, inserting two lines that enable it.

That's all.

Hard Way

download as above

diff sentry.pl /var/db/sentry/sentry.pl

resolve any configuration differences

cp sentry.pl /var/db/sentry/sentry.pl
