Howto make a permanent IP-Connection between the Nokia 3650 and a Linux-PC!?!
News
06/25/2003 adding part 6. Application using TCP/IP06/16/2003 First version of this HOWTO
0. Hints
At the moment there is no Nokia-Software for dataexchange between the Mobilephone 3650 und Linux. To portate some well known software like ftpd or nfsd a TCP/IP-Connection is obsolete. So where is the problem? A connection from Linux to the 3650 over DUND to use the phone as a Modem works well. But if you want to make a ppp-connection over SPP, the Nokia will block. So this is bad, or? No then after this the mobilephone tries to open a ppp-connection to the Linux-PC by itself. If you accept this one, the Nokia tries to resove the following DNS-Address "wsockhost.mrouter". These PC should be in your local network, in case there is no reply from the DNS or the PC is not answering, the connection will be closed. If all this went well, you have a stable IP-Connection...1. Preferences
- Working Bluetoothsupport of your Linuxinstallation.
I actually use:
-Kernel 2.4.19
-bluez (libs, utils, sdp, pan)
-USB-Bluetooth-Adaptor from EpoX
More information on Bluetooth in Linux you may find find here or there.
- pppd / dund to accept the Nokia ppp-request.
- DNS-Server (bind) to resolve "wsockhost.mrouter".
2. On Linux side...
After having a working Linux-Bluetooth-System you can continue. Best first try some data exchange with ussp-push or p3nfs).2.1 SPP
You have to support the SP-Profile for pppd/dund. Type the following:sdptool add --channel=2 SP
2.2 DNS-Configfiles
To resolve "wsockhost.mrouter" you should modify your bind configuration. Exsamples:/etc/named.conf:
options {
directory "/var/named";
cleaning-interval 120;
statistics-interval 0;
notify no;
};
zone "localhost" in {
type master;
file "localhost.zone";
};
zone "0.0.127.in-addr.arpa" in {
type master;
file "127.0.0.zone";
};
zone "." in {
type hint;
file "root.hint";
};
zone "mrouter" {
type master;
file "/var/named/mrouter.hosts";
};
EOF
/var/named/127.0.0.zone:
$TTL 2D
@ IN SOA localhost. root.localhost. (
42 ; serial (d. adams)
1D ; refresh
2H ; retry
1W ; expiry
2D ) ; minimum
IN NS localhost.
1 IN PTR localhost.
EOF
/var/named/localhost.zone:
$TTL 2D
@ IN SOA @ root (
42 ; serial (d. adams)
1D ; refresh
2H ; retry
1W ; expiry
2D ) ; minimum
IN NS @
IN A 127.0.0.1
EOF
/var/named/mrouter.hosts:
$ttl 38400
mrouter. IN SOA bernd. bernd.pnd. (
2003051402
10800
3600
604800
38400 )
mrouter. IN NS bernd.
wsockhost.mrouter. IN A 192.168.2.1
192.168.2.1.mrouter. IN PTR wsockhost
EOF
2.3 PPP-Server
An exsample for your /etc/ppp/options:noauth
local
modem
proxyarp
debug
ms-dns 192.168.1.1 # DNS-Server who resolvs "wsockhost.mrouter"
192.168.1.100:192.168.1.200 # IP-Addresses for host and Mobilephone
2.4 dund
To act as a ppp server, type this:dund --listen --channel=2
2.5 Start the SP-Connection to your 3650
Solong everything is OK. Now you should type..rfcomm connect 2 <MAC-des-Nokia-3650> 2
and wait for establishing the ppp connection from your mobilephone...fine
3. 3650 side...
Enable Bluetooth and may allow connections from the Linuxbox.4. Testing...
For exsample try the Opera browser to view some html sides.5. Stuff...
To forward the requests from your Nokia through an ISP-Connection do the following:- IP-Forwarding:
echo 1 > /proc/sys/net/ipv4/ip_forward - NAT (Network Adress Translation)
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
Change the ppp0 to your ppp-Interface.
