He encontrado una manera de revertir el tether de un dispositivo iOS, o conectarlo a Internet a través del cable usb solamente. Muchas de las formas más antiguas de hacer esto requerían una conexión de datos activa, ya que había que configurar el proxy para esa interfaz manualmente para utilizar un túnel tcp usb. El host es un Mac que ejecuta la vista previa para desarrolladores de macOS High Sierra. El dispositivo es un iPhone 4s con iOS 7.1.2 con jailbreak. La forma en que lo he hecho es la siguiente:

Crear un túnel pppd. Primero, instalé libimobiledevice para configurar un túnel tcp para ingresar con ssh a mi idevice más tarde:

iproxy 2022 22

entonces un túnel dedicado para que pppd lo utilice:

iproxy 4444 4444

Ahora me conecto a mi idevice: ssh localhost -p 2022

Ahora, el túnel pppd, primero desde mi idevice:

pppd noipdefault nodetach usepeerdns pty "nc -l -p 4444 localhost"

Observe que estoy escuchando una conexión desde el cliente. Esto se debe a que iproxy sólo permite que se inicie una conexión desde el ordenador anfitrión. Ahora, en el ordenador anfitrión:

pppd 172.16.1.2:172.16.1.3 proxyarp usehostname ms-dns 8.8.8.8 nodetach pty "nc localhost 4444"

Estoy utilizando nc como mi conexión, de nuevo debido a la limitación de la conexión de sólo host.

Tras unos segundos, tanto el proceso pppd del host como el del cliente muestran los detalles de la conexión:

client pppd:

Wed Sep 13 00:36:28 2017 : publish_entry SCDSet() failed: Success!

Wed Sep 13 00:36:20 2017 : Committed PPP store

El idevice está ahora conectado a mi máquina anfitriona. He instalado adv-cmds y network-cmds desde Cydia, y así tengo disponibles ifconfig, route, etc. Desde mi idevice:

$ ifconfig

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
    inet 127.0.0.1 netmask 0xff000000 
pdp_ip0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
pdp_ip1: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
pdp_ip2: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
pdp_ip3: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
en0: flags=8822<BROADCAST,SMART,SIMPLEX,MULTICAST> mtu 1500
    ether c2:9f:42:7f:cd:1d 
ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
    inet 172.16.1.3 --> 172.16.1.2 netmask 0xffff0000

Ya funciona. Pero aún no puedo usarlo. El idevice no tiene ninguna ruta para esta nueva interfaz. Mi red doméstica está en la red 172.16, y quiero alcanzar todos los dispositivos en ella. Así que ejecuto:

route add -net 172.16 172.16.1.2

Ahora, si abro safari, puedo acceder a todos los dispositivos de esa red. Si voy más allá, y hago

route add default 172.16.1.2

Puedo acceder a todas las direcciones IP numéricas, externas e internas. Sin embargo todos los nombres de dominio siguen devolviendo el temido "Safari no puede abrir la página porque su iPhone no está conectado a Internet". Veamos la configuración de mi ruta:

$ netstat -rn

Tuve la corazonada de que iOS incluye algunas herramientas relacionadas con el sistema preinstaladas, y así es como encontré pppd.

$ ls /usr/sbin
BTAvrcp     BlueTool  addNetworkInterface  distnoted          ipconfig         mkfile   nvram     rtadvd    startupfiletool  traceroute6  vipw       zic

BTServer    accton    daily        iostat         mediaserverd     notifyd  racoon    sshd  traceroute   vifs         zdump

addNetworkInterface es una herramienta que nunca había visto antes.

/usr/sbin/addNetworkInterface --help
options:

[-i <interface>]
[-c <controller>]
[-p] persistent host detection
[-s] route logging to syslog

Probemos con ppp0:

/usr/sbin/addNetworkInterface -i ppp0 
Looking for interface ppp0
Looking for all controllers
Looking for network interfaces...

No parece hacer nada. ¿Tal vez no se detecta el DNS? En /usr/sbin también encontré scutil, que ya había visto antes, en OS X. Así que,

   $ scutil --dns
resolver #1

resolver #2
  domain   : local
  options  : mdns
  timeout  : 5
  order    : 300000

resolver #3

resolver #7

  options  : mdns
  timeout  : 5
  order    : 301000

Hmm, no hay 8.8.8.8 (google public dns) y el resolver #1 está vacío. Veamos si iOS ve ppp0:

$ scutil --nwi
IPv4 network interface information

IPv6 network interface information

Aha, iOS no ve mi interfaz ppp0. Sin embargo, resulta que tengo un servidor L2TP vpn en 172.16.12.1. Intenté añadir una vpn a través de la configuración para ello, ¡y se conecta! Tengo acceso a Internet, y el DNS se resuelve. Veamos qué ha cambiado:

$ ifconfig

    inet 172.17.0.6 --> 172.16.12.1 netmask 0xffff0000

Bien, probemos con scutil:

$ scutil --nwi
IPv4 network interface information
    ppp1 : flags 0x5 (IPv4,DNS)
           reach 0x3 (Reachable,Transient Connection)

Aha, iOS sí ve esa conexión vpn. Veamos ahora las tablas de enrutamiento:

$ netstat -rn

172.17             ppp1               USc         0        0   ppp1

Note que mi servidor vpn L2TP asigna direcciones en la red 172.17. Interesante... pero eso es exactamente lo que hice con mi configuración pppd.

Probemos a ver qué ve scutil. Puedes entrar en modo interactivo simplemente invocando scutil sin argumentos.

Así que iOS tiene un montón de interfaces establecidas. Sólo me interesa la activa, mi vpn l2tp, que es ppp1. Así que:

> get State:/Network/Global/IPv4
> d.show
<dictionary> {
  PrimaryInterface : ppp1
  PrimaryService : FF84E6AB-D5D4-4CE0-A9EE-FBAB5DE824C7
  Router : 172.16.12.1
}

> get State:/Network/Global/DNS
> d.show
<dictionary> {
  ServerAddresses : <array> {

}

Así que ahí se define. Vamos a obtener todos los valores para el PrimaryService:

  subKey [65] = com.apple.MobileInternetSharing

Toda la configuración ha desaparecido. Por eso no funciona. Ten en cuenta que el servicio AAAAAAAA-AAAA-AAAA-AAAAAAAA es uno que intenté hacer manualmente y añadir todas las claves como estaban configuradas para ppp1 pero sustituyéndolo por ppp0 pero no funcionó.

Entonces, ¿es posible añadir ppp0 a través de scutil o de alguna otra manera, de manera que las direcciones DNS funcionen, y iOS sea consciente de que ES una conexión a Internet, que las aplicaciones pueden utilizar?
