Installation De Ss5 Sur Une Debian 5

ss5 est un service de proxy SOCKS très performant, développé par une seule personne je tiens à le souligner ! J’ai eu à l’installer sur une Debian 5, et j’ai donc réalisé un petit script pour automatiser tout cela.

On installe…

N’oubliez pas de préciser le numéro de version complet dans la variable VER :

1
2
3
4
5
6
7
8

#!/bin/bash
VER="3.8.4-1"
DIR="/tmp/ss5_install"
apt-get update
apt-get -y install build-essential libpam0g-dev libpam-devperm libldap2-dev libssl-dev

if ! [ -d "$DIR" ];then mkdir $DIR fi
cd $DIR wget
http://downloads.sourceforge.net/project/ss5/ss5/$VER/ss5-$VER.tar.gz

tar xzf ss5-$VER.tar.gz

VER=`echo $VER | cut -d "-" -f 1`

cd ss5-$VER

./configure --with-defaultport=80 && make clean && make && make install

Une particularité du .tar.gz de ss5 c’est de ne pas intégrer le numéro de sous-version (“-2” par exemple) dans le nom du dossier, ce qui oblige à cette pirouette dans le script :

VER=`echo $VER | cut -d "-" -f 1`

…et on démarre !

J’ai aussi créé un script pour init.d (assez basique), basé sur /etc/init.d/skeleton. Il intègre quelques options comme le port par défaut ou le lancement en mode daemon (DAEMON_ARGS="-t -u root -b 0.0.0.0:80") :
