Hi
I have three usb adapters and three linux pc.
Now one pc is a pan server, the other two are clients.
At the server side I allocate ip with a DHCP server.
using the following command to start pan server:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
sdpd
pand -s -M --role=3DNAP -n
echo '1' > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -A FORWARD -i bnep0 -j ACCEPT
iptables -A FORWARD -i bnep1 -j ACCEPT
iptables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
and the /etc/bluetooth/pan/dev-up file is:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
#!/bin/sh
echo "dev-up working ,interface is $1!!!"
ifconfig $1 10.0.0.1
/etc/init.d/dhcp3-server restart 2>&1 > /dev/null
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
restart the DHCP server when a bnep interface is created.
and at the two client sides using the following command to start
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
sdpd
pand --role PANU --search --persist -n
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
and the /etc/bluetooth/pan/dev-up file is
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
#!/bin/sh
dhclient bnep0
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
/etc/dhcpd.conf is
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
subnet 10.0.0.0 netmask 255.255.255.0 {
=09option routers 10.0.0.1;
=09option subnet-mask 255.255.255.0;
=09option domain-name "example.com";
=09option domain-name-servers 202.112.17.33;
=09option time-offset -18000; # Eastern Standard Time
=09range 10.0.0.3 10.0.0.100;
}
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
the question is two client can get their ip address for the DHCP server
but only the first one connected to the servercan ping the server, the
later one can not.
I don't know why?
I try to modify the /etc/bluetooth/pan/dev-up at the server side
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
#!/bin/sh
echo "dev-up working ,interface is $1!!!"
ifconfig bnep0 10.0.0.1
ifconfig bnep1 10.0.0.2
/etc/init.d/dhcp3-server restart 2>&1 > /dev/null
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D
the result is the same.
How can I get multi pan client online?
thank you !
