環境

• OS : Debian GNU/kFreeBSD unstable amd64

• SONY VAIO TZ VGN-93NS

• CPU : Core 2 Duo U7700

• memory : 2GB

• disk : SSD 160GB

• USBモデム : NTT docomo L-02C (ファームウェア：V10d)

事前準備

• USBモデム「L-02C」を用意し、SIMカードを入れておきます。

• 今回は私が契約しているIIJmioを使いました。

必要パッケージのインストール

# apt-get update
# apt-get install freebsd-ppp usb-modeswitch

L-02CをPCに差します

以下のログが出てハードウェアを認識します。

# dmesg
ugen4.7:  at usbus4 (disconnected)
u3g0: at uhub4, port 5, addr 7 (disconnected)

cd0: 40.000MB/s transfers
cd0: Attempt to query device size failed: NOT READY, Medium not present
cd0: quirks=0x10<10_BYTE_ONLY>

L-02Cをモデムモードに変更します

ここはLinuxでよくあるパターンと同じです

usb_modeswitchでL-02Cをモデムモードに変更するための設定ファイルを作成します。

# vi /etc/usb_modeswitch.d/L02C.conf
########################################################
# LG L-02C LTE modem

DefaultProduct=0x61dd

NeedResponse=1
CheckSuccess=20

以下のメッセージが出て、モデムモードへの変換ができます。

# usb_modeswitch -c /etc/usb_modeswitch.d/L02C.conf

すると以下のデバイスができます。

# ls /dev/cua*
/dev/cuaU0.0       /dev/cuaU0.1       /dev/cuaU0.2       /dev/cuaU0.3

/dev/cuaU0.0.lock  /dev/cuaU0.1.lock  /dev/cuaU0.2.lock  /dev/cuaU0.3.lock

dmesgでログを確認すると、u3g.koというドライバを利用するデバイスであることがわかります。

# dmesg

pppの設定ファイルを作成します

freebsdのpppコマンド形式の設定ファイルを作成します

# vi /etc/ppp/ppp.conf

default:

pppを実行してインターネットに接続します。
