[Bluez-users] DHCPD and Bluetooth

[Bluez-users] DHCPD and Bluetooth

[Rob Taft]

[-- Attachment #1: Type: text/plain, Size: 936 bytes --]

I currently have a setup where I have a Bluetooth adapter on a Linux box, and one on Windows.  Everything is configured properly.  I connect from the Windows Bluetooth adapter to the Linux one via "Local Area Connection 2" in XP over TCP/IP.  I manually type "ifconfig bnep0 192.168.3.1" to assign the adapter an IP, then I have to restart DHCPD to acquire an IP address over Bluetooth.  This all works great.

My first question is:  Is there a way to recognize when a connection is made, so I can create a script or some code to automatically set bnep0 to 192.168.3.1 and restart the dhcp server?

I only have 2 Bluetooth adapters.  What if I used a 3rd from windows to connect to Linux at the same time another one is connected.  Will it allow multiple connections?  Will it show up as bnep1 or still use bnep0?

I know Slackware has hotplug scripts. You might want to look there.

Changing my OS isn't exactly an option at this point.

All distributions have hotplug scripts inside. Just use you package system and 
install it

Re: [Bluez-users] DHCPD and Bluetooth

[Rob Taft]

hotplug is installed.  I added some lines to /etc/hotplug/usb/bluefw to
verify that it is getting executed, but it never does.  Nor does it get
executed when I type "hotplug usb" or "hotplug usb/bluefw"

Secondly, it seems to me that the hotplug scripts supposed to be called when
a hardware device is connected.  This is not my issue.  I am trying to get a
Windows (or any OS) Client to connect to a Linux Server via Bluetooth.  When
there is nothing connected to the server, bnep0 is not listed in ifconfig.
Now I've managed to get it to automatically assign an IP to the Server's
Bluetooth when a Client connects by creating
/etc/sysconfig/network-scripts/ifcfg-bnep0 with the following data:

DEVICE=bnep0
ONBOOT=yes
USERCTL=no
PEERDNS=no
IPADDR=192.168.3.1
NETMASK=255.255.255.0
BROADCAST=192.168.3.255

This solves half my problem..setting the IP of bnep0 when a client connects,
since the IP is lost when the client disconnects.

The other half of the problem is the DHCP server.  Once the client
disconnects from the server, bnep0 drops the IP, and DHCP no longer serves
IP's for it.  When a new client connects, I need the DHCP server to begin
serving bnep0 again.  One way to do it is to restart the DHCP server, but if
I take that approach, I need to know when the client connets so I can
restart it.  I don't think hotplug is what I am looking for since it is
hardware connection based.

This is not only hardware connection based. When you try setup network from
remote device, that kernel call /sbin/hotplug with NET action.
You can edit script "/etc/hotplug.d/default/default.hotplug" or other in your 
distribution and uncomment line "DEBUG=yes export DEBUG".
Later you can look in to log file for interesting messages ;-)
In this case will be probably interesting script /etc/hotplug/net.agent.

Best regards,

Pavel Ruzicka

Re: [Bluez-users] DHCPD and Bluetooth

I think I'm almost there.
I noticed that it is not HW based after I posted.  I saw in
/var/log/messages a message that occurred ever connection:

May 12 17:01:20 SMED /etc/hotplug/net.agent: invoke ifup bnep0

So I went into the net.agent file and found this line that matched the
output:

debug_mesg invoke ifup $INTERFACE

I added more lines to that so now it looks like this:

if [ -x /sbin/ifup ]; then
    debug_mesg invoke ifup $INTERFACE
    debug_mesg LALALALALALALALALALA #ADDED THIS
    exec /sbin/ifup $INTERFACE
    debug_message Attempting to restart dhcpd.    #ADDED THIS
    exec /etc/init.d/dhcpd restart  #ADDED THIS
else
     mesg "how do I bring interfaces up on this distro?"
fi

I then restarted my entire system....and the 2nd 2 lines were never reached.
I added the LALALA line after and that appears in the logs...so I'm guessing
that "exec /sbin/ifup $INTERFACE" is causing the script to exit
