Voici un petit article décrivant comment recycler votre vieille IPod Touch 1G en serveur PHP.
Mise à jour d’IOS
Pour mettre à jour son IOS rien de plus facile, on lance itunes, on connecte son IPod Touch 1G et on fait la mise à jour / restauration de l’IOS. Ici on me propose la dernière version disponible à savoir 3.1.3
JailBreak
Le but de la manipulation est de pouvoir utiliser des produits open source sur l’IPod. Dans notre cas nous voulons installer php.
Le JailBreak d’un ancien IOS tel que le 3.1.3 est extrêmement simple. Lancer le safari sur l’IPod et aller sur le site www.jailbreakme.com, ensuite il suffit de demander le jailbreak.
Cydia
Le JailBreak installe Cydia un outil de gestion de package qui va nous permettre d’installer ce que l’on souhaite.
Avant tout une mise à jour de Cydia s’impose, lors du premier démarrage il nous demande le mode de fonctionnement, nous allons prendre développeur.
ssh et aptitude
Grace à Cydia (une fois mis à jour) on installe les packages suivants:
- openssh (permettant la connexion à votre IPod Touch en ssh)
- aptitude (un gestionnaire de package plus sympa que apt-get)
ssh et itunnel
Je souhaite pouvoir me connecter à mon IPod Touch via le cable apple. Pour ce faire j’utilise itunnel. Télécharger le produit puis:

Après quelques recherche il se trouve que ma version de gcc est trop récente. Je corrige donc le Makefile:
TARGET := itunnel SRCDIR := . SOURCES := itunnel.c iphone.c OBJS := $(patsubst %.c,%.o,$(wildcard $(SRCDIR)/*.c)) CC := gcc CFLAGS := -Wall -g -O0 -I/usr/local/include/ #LDFLAGS := -L/usr/local/lib -lpthread -lusb -lrt -liphone LDFLAGS := -L/usr/local/lib -lpthread -lusb -lrt all: $(TARGET) $(TARGET): $(OBJS) $(CC) $(OBJS) -o $@ $(CFLAGS) $(LDFLAGS) %.o: %.m $(CC) -c $(CFLAGS) $< -o $@ clean: rm $(TARGET) $(OBJS)
On relance la compilation
scolas@scolas:~/perso/ipod/utils/itunnel-0.0.9$ make gcc -Wall -g -O0 -I/usr/local/include/ -c -o iphone.o iphone.c gcc -Wall -g -O0 -I/usr/local/include/ -c -o itunnel.o itunnel.c gcc ./iphone.o ./itunnel.o -o itunnel -Wall -g -O0 -I/usr/local/include/ -L/usr/local/lib -lpthread -lusb -lrt
On démarre itunnel (2 fois pour démonter le système fichier ipod)
scolas@scolas:~/perso/ipod/utils/itunnel-0.0.9$ ./itunnel - iphone get device error: -5 ERROR: failed to connect to iphone. quitting. quit ok. scolas@scolas:~/perso/ipod/utils/itunnel-0.0.9$ ./itunnel get_iPhone() success - successfully got device server waiting for ssh connection on port 3023
On se connecte et on change le mot de passe (par défaut alpine):
scolas@scolas:~/perso/ipod/utils/itunnel-0.0.9$ ssh -p 3023 localhost -l root The authenticity of host '[localhost]:3023 ([127.0.0.1]:3023)' can't be established. RSA key fingerprint is e8:54:de:b3:69:0e:c8:40:9f:f9:0f:4a:8e:d9:d8:f6. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '[localhost]:3023' (RSA) to the list of known hosts. root@localhost's password: sebs-iPod:~ root# passwd Changing password for root. New password: Retype new password: sebs-iPod:~ root# exit logout Connection to localhost closed.
Connexion ssh via clef
Pour pouvoir utiliser des scripts nous allons maintenant nous authentifier en ssh via clef. Tout d’abord générons la clef:
scolas@scolas:~/perso/ipod/utils/itunnel-0.0.9$ ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/home/scolas/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/scolas/.ssh/id_rsa. Your public key has been saved in /home/scolas/id_rsa.pub.
Copions la clef sur l’ipod:
scolas@scolas:~/perso/ipod/utils/itunnel-0.0.9$ scp -P 3023 ~/.ssh/id_rsa.pub root@127.0.0.1: root@127.0.0.1's password: id_rsa.pub 100% 398 0.4KB/s 00:00
Autorisons la clef à se connecté sur l’ipod:
scolas@scolas:~/perso/ipod/utils/itunnel-0.0.9$ ssh -p 3023 localhost -l root root@localhost's password: sebs-iPod:~ root# mkdir .ssh sebs-iPod:~ root# cat id_rsa.pub >.ssh/authorized_keys sebs-iPod:~ root# exit logout Connection to localhost closed. scolas@scolas:~/perso/ipod/utils/itunnel-0.0.9$ ssh -p 3023 localhost -l root sebs-iPod:~ root# exit logout Connection to localhost closed.
Installation de PHP et divers…
Ensuite on installe les packages dont on a besoin (au moins php et lighttpd):
scolas@scolas:~/perso/ipod/utils/itunnel-0.0.9$ ssh -p 3023 localhost -l root sebs-iPod:~ root# aptitude install php rsync lighttpd vim
Configuration du serveur web lighttpd
Voici le fichier de configuration que j’utilise
# sebs-iPod:~ root# cat /etc/lighttpd/lighttpd.conf
server.document-root = "/private/var/htdocs"
server.port = 80
server.tag ="lighttpd"
server.errorlog = "/etc/lighttpd/logs/error.log"
accesslog.filename = "/etc/lighttpd/logs/access.log"
server.modules = ("mod_access","mod_accesslog","mod_fastcgi","mod_rewrite","mod_auth","mod_fastcgi")
index-file.names = ( "index.html", "index.php" )
#Configuration PHP
fastcgi.server = (".php" =>
("localhost" =>
("bin-path" => "/usr/bin/php-cgi",
"socket" => "/tmp/php.socket")
)
)
Il ne faudra pas oublier que créer le répertoire /private/var/htdocs et de mettre le contenu du site web dedans.
On créé un script de démarrage (ne pas oublier de donner les droits en exécution):
sebs-iPod:~ root# ls -l /usr/bin/lighttpd.sh -rwxr-xr-x 1 root wheel 50 Oct 11 12:58 /usr/bin/lighttpd.sh sebs-iPod:~ root# cat /usr/bin/lighttpd.sh #!/bin/sh lighttpd -f /etc/lighttpd/lighttpd.conf
Ensuite on crée un script pour le démarrage automatique:
sebs-iPod:~ root# cat /System/Library/LaunchDaemons/com.lighttpd.startup.plist <!--?xml version="1.0" encoding="UTF-8"?--> Label com.lighttpd.startup ProgramArguments /usr/bin/lighttpd.sh RunAtLoad
Déploiement du site web
Voici un petit script qui permet de déployer automatiquement le site web sur l’ipod:
scolas@scolas:~/bin$ cat ipod_php_deploy.php rsync -av --delete --progress --inplace --bwlimit=100 --rsh='ssh -p3023' /var/www root@127.0.0.1:/etc/lighttpd/htdocs
On notera la limitation du débit, sans elle itunnel ne répond plus.
