How to Install portsentry on ubuntu 14.04/16.04

Portsentry源下载:http://nchc.dl.sourceforge.net/sourceforge/sentrytools/portsentry-1.2.tar.gz
从sourceforge.net下载的包要做如下修改:
vi +1584 portsentry.c
将584和1585两行合并为一行!
如:printf (“Copyright 1997-2003 Craig H. Rowland \n”);

本站下载的portsentry包已修正,直接解压后make linux & make install即可。

tar -zxvpf portsentry-1.2.tar.gz
cd portsentry_beta
make linux
make install
