Tethering FreeBSD PC & Android Smart Phone

  • Purpose: Travelling, Android WLAN to internet, FreeBSD PC with no WLAN hardware via Android to Internet
    FreeBSD pc as client, via USB to Android as router/server with WLAN; then via WLAN to an Internet DSL router.
    + Tethering - common elements for either direction

    • PC
      • Connecting usb creates these in /dev/ :
        • lrwxr-xr-x 1 root wheel 9 Nov 9 21:24 ./ugen1.6 -> usb/1.6.0
        • crw------- 1 root operator 0x9a Nov 9 21:24 ./usb/1.6.0
        • crw------- 1 root operator 0x9c Nov 9 21:24 ./usb/1.6.1
        • crw------- 1 root operator 0x9d Nov 9 21:24 ./usb/1.6.3
      • For urndis USB Remote NDIS Ethernet device driver, Use FreeBSD-9.3-RELEASE or newer, not 9.2 & not 10.0, .
      • /boot/loader.conf Add if_urndis_load="YES" Or
        /sys/amd64/conf/ Add "device urndis"
    • Android
      • Touch "Settings ; Connections ; Tethering and portable hot spot ; USB tethering";
        After a few seconds it shows "Tethered" + a green tick.
    • PC
      • The tethering causes these in /dev/ :
        • Disappears: usb/1.6.3
        • Adds: crw------- 1 root operator 0xa1 Nov 9 21:24 ./usb/1.6.2
      • ifconfig -a # Or
        ifconfig ue0
        • I should be able to call ifconfig from attach in devd.conf, but I fail with "Executing 'logger Unknown USB device: vendor 0x04e8 product 0x6863 bus uhub4' "
        • Shows: ue0: flags=8802<BROADCAST, SIMPLEX, MULTICAST> metric 0 mtu 1500
      • cp /etc/ resolv.conf /tmp/ resolv.conf.cp
      • Caution: If PC is configured with /etc/ rc.conf ifconfig_wlan0="DHCP" enabling DHCP for WLAN, the next dhclient will over-write /etc/ resolv.conf with
        "nameserver 192.168.42.129",
        which kills routing to other devices on PC's ethernet.
      • dhclient -d ue0 # Configures network interface using DHCP
      • cat /tmp/ resolv.conf.cp /etc/ resolv.conf | grep '^nameserver' | sort | uniq > /tmp/ resolv.conf.tmp
      • mv /tmp/ resolv.conf.tmp /etc/ resolv.conf
      • vi /tmp/ resolv.conf.cp /etc/ resolv.conf
      • ifconfig ue0
      • inet 192.168.42.139 netmask 0xffffff00 broadcast 192.168.42.255
      • Shows local address assigned by Android to PC (a class C private address).
      • arp -a -i ue0 # Display IP & MAC numbers of interface.
        • (192.168.42.139) at 0f:0f:0f:0f:0f:0f on ue0 permanent [ethernet]
      • Android: Browser 192.168.42.139/cgi-bin/printenv shows REMOTE_ADDR="192.168.42.129"
      • Instead of dhclient and repairing /etc/ resolv.conf, as [just my?] Android allocates the same numbers each time, one can just:
      • ifconfig ue0 192.168.42.139
    • Android: After enabling tethering on android, the android browser can see PC apache httpd (where I can stage downloaded android apps from internet).
    • FreeBSD: ping 192.168.42.129
    • Android:
      • Stops android screen becoming non responsive.
      • Touch Internet icon. A browser starts
      • Each touch on a browser link URL (even a numeric local one), Android shows:
        "No network connection. Mobile data turned off. Connected to Wi-Fi network instead or turn on mobile data and try again."
        Just click OK each time, then it shows the new page.
      • Touch URL bar at top.
      • Type in 192.168.42.139
    • Purpose: At home, debugging:
      Android as client, via USB to FreeBSD PC as router; then PC via ethernet (local class C private addresses) to a LAN proxy gateway connecting to Internet

      • (See also above for some common stuff, eg about FreeBSD urndis).
      • See Also freebsd . org / doc / handbook / network - usb - tethering . html
      • PC
        • /etc/ rc.conf: gateway_enable="YES"
        • PC sysctl net.inet.ip.forwarding=1
      • Android
      • xinotes. net / notes / note / 1496 shows:
        cat /proc/net/route
        ip route show
        So I tried:
        route add default gw 192.168.42.139 dev rndis0
        Which error-ed: Operation not permitted,
        & still error-ed after
        Settings -> General -> Developer Options ->
        { USB Debugging : Allow = ON ; Allow Mock locations : ON }
        JJLATER Not sure if needed.
        So I assume syntax OK, I "just" need to root the device.
      • Meantime on PC / usr / local / etc / apache22 / httpd.conf
        <IfModule mod_proxy.c>
        ProxyRequests On
        <Directory proxy:*>
        Order deny,allow
        Deny from all
        Allow from 192.168.42.129
        <Directory>
        ProxyVia On
        NoCache *
        <IfModule>
        This works, allow android to access other internal servers
        but not sure how to get cascade of apaches, so the apache on PC of the smart phones should use the LAN gate apache as a proxy.
      • To try: ipfw packet diversion direct from phone USB to LAN host=gate proxy.
      • I gave up on above, & now use WLAN for Android, which is safer, as now the Android is on my WLAN sub net, which my firewall does not allow to communicate to internal trusted BSD net.

    Path names below are for a Samsung Galaxy Note 3 with a collection of apps, for a phone that has Not been rooted ... yet. (Maybe more paths will work once it is rooted).

    Notes: Other sites re. tree hierarchy:
"The main hardware platform for Android is the 32-bit ARMv7 architecture. The Android-x86 project provides support for the x86 architecture ... it is possible to run Android natively on regular PC hardware with a keyboard and a mouse,[87][88][89] with versions of Android, including 4.4, download-able from the Android-x86 project."
