現在、ジャカルタではＬＡＮのあるホテルに宿泊しているのだが、折角 Nokia N70 を持っているので、bluetooth でPCに接続し、モデムとして使ってみる実験をしてみた。電話回線は、XL bebas。まずは、N70からGPRSで接続するよう XL に登録して、接続を確認してみる。

以下、PC (Gentoo Linux on MSI S271）での設定。

bluetoothの設定は、一部古い情報があるものの、Gentooのガイドを参考にした。カーネルの設定や必須アプリケーションは、上記ページを参考されたい。

僕の場合、/etc/bluetooth/hcid.confはこんな。

# HCI daemon configuration file.
## HCId options
options {
 # Automatically initialize new devices
 autoinit yes;
 # Security Manager mode
 #   none - Security manager disabled
 #   auto - Use local PIN for incoming connections
 #   user - Always ask user for a PIN
 #	security user;
 # Pairing mode
 #   none  - Pairing disabled
 #   multi - Allow pairing with already paired devices
 #   once  - Pair once and deny successive attempts
 pairing multi;
 # Default PIN code for incoming connections
 #passkey "0987";
}
# Default settings for HCI devices
device {
 # Local device name
 #   %d - device id
 #   %h - host name
 name "BlueZ at %h (%d)";
 # Local device class
 #class 0x000100;
 class 0x3e0100;
 # Default packet type
 #pkt_type DH1,DM1,HV1;
 # Inquiry and Page scan
 iscan enable; pscan enable;
 # Default link mode
 #   none   - no specific policy
 #   accept - always accept incoming connections
 #   master - become master on incoming connections,
 #            deny role switch on outgoing connections
 lm accept;
 # Default link policy
 #   none    - no specific policy
 #   rswitch - allow role switch
 #   hold    - allow hold mode
 #   sniff   - allow sniff mode
 #   park    - allow park mode
 lp rswitch,hold,sniff,park;
}

/etc/bluetooth/rfcomm.conf はこんな

## RFCOMM configuration file.#
rfcomm0 {
 # Automatically bind the device at startup
 #bind no;
 bind yes;
#
 # Bluetooth address of the device
 device XX:XX:XX:XX:XX:XX;
##
 # RFCOMM channel for the connection
 channel	3;
##
 # Description of the connection
 comment "Nokia N70";
}

ペアリングのところで、pin_helperに関して、やや混乱した。Gentoo Guide では、明確に書かれていない。まず、

% rfcomm show /dev/rfcomm0rfcomm0: 00:1B:EE:0B:1D:BD channel 3 clear

となっている必要がある。もし

% rfcomm show /dev/rfcomm0rfcomm0: XX:XX:XX:XX:XX:XX channel 3 closed

となったら、

% sudo rfcomm release /dev/rfcomm0% sudo rfcomm bind /dev/rfcomm0

とすれば、望んでいる状態になるはず。

ここで、

% passkey-agent 1234 XX:XX:XX:XX:XX:XX（←ここはN70のbluetooth address）

としたうえで、別のコンソールから

% sudo rfcomm connect 0

とすれば、N70 側でPIN（上記の例では、1234）を要求してくる。N70側でPINを打てば、ペアリングができる。

次はpppの設定。僕は、 pppconfig を使った。

• Provider Name: proXL （適当に）
• DNS: Dynamic
• Authentification Method: PAP
• User Name: xlgprs
• Password: proxl
• Speed: 115200
• Pulse or Tone: Tone
• Phone No.: *99#
• Choose Modem Config Method → Yes → manual → /dev/rfcomm0

と設定する。（参考ページ）

/etc/ppp/peers/proXLは、

# This optionfile was generated by pppconfig 2.3.17.
 #
 #
hide-password noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/proXL"
debug
/dev/rfcomm0
115200
defaultroute
noipdefault
user "xlgprs"
remotename proXL
ipparam proXL
usepeerdns

/etc/chatscripts/proXLは、（ちょっと手書きで修正したけど）

# This chatfile was generated by pppconfig 2.3.17.
# Please do not delete any of the comments. Pppconfig needs them.
#
# ispauth PAP
# abortstring
ABORT BUSY ABORT 'NO CARRIER' ABORT VOICE ABORT 'NO DIALTONE' ABORT 'NO DIAL TONE' ABORT 'NO ANSWER' ABORT DELAYED
# modeminit
'' ATZOK-AT-OK "ATQ0 V1 E1 S0=0 &C1 &D2"
# SetupPDP? in +CGDCONT
OK-AT-OK 'AT+CGDCONT=1,"IP","www.xlgprs.net","0.0.0.0",0,0'
# ispnumber
OK-AT-OK "ATDT*99#"
# ispconnect
CONNECT dc
# prelogin
# ispname
# isppassword
# postlogin
# end of pppconfig stuff

僕の場合は、pdnsdを使っているので、/etc/pdnsd/pdnsd.conf に以下を加える。

server {
 label= "proXL";
 ip = 202.152.254.245,202.152.254.246;
 proxy_only=on;
 timeout=10;
 uptest=none;
 interface=any;
 interval=600;
 purge_cache=off;
}

接続は、pon proXL。ログはこんな感じになるはず。
