eth0 to wlan0 Bridge

Tiny Core Base > Raspberry Pi

<< < (3/4) > >>

yeme:
I have had some success in getting this going except with 2 problems for me:

1. I cannot SSH via PuTTY into PiCore after the bridge is set and working
2. The bridged connection always disconnects after about 30 minutes.

When it is up, I can receive an IP for the connected client (or the client can have a static IP) and browse with performance similar to my RPi bridge I've been using. I can also ping my LAN and web from my client (laptop) and browse at network level shared folders on my LAN. I can also ping and browse network shares from my LAN to the connected client.

I also was able to have my connected IP camera work as it should for the 30 minute period the bridge was up. I could not however connect to the camera's web server admin page via browser as would normal.

Here is my modified bootlocal.sh script adapting Paul_123's original post:

Details:

RPi B+
PiCore 7 alpha 8
Added bridge-utils.tcz (thanks to bMarkus)

Here is my modified bootlocal.sh script using Paul_123's original post:

--- Quote ---#wlan0 up
/usr/local/bin/wifi.sh -a -w 2>&1 > /tmp/wifi.log
sleep 5s
ifconfig eth0 up
ifconfig wlan0 up

#setup br0
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 wlan0
sleep 10s
ifconfig br0 up

# wpa piece
#wpa_supplicant -Dwext -iwlan0 -bbr0 -c /etc/wpa_supplicant.conf & #(could not get this work for me)

#set br0 ip
sleep 5s
udhcpc -i br0
--- End quote ---

Upon startup when udhcpc is started I see:

getting lease (which it does 192.168.4.70)
deleting routers
route:.....no such process
adding dns 192.168.4.1 (my LAN gw/router's IP )

My ifconfig - this shows an IP assigned to the wlan0 and the Br0 whereas the ifconfig for the working bridge on the RPi only has an IP assigned to the Br0

Finally my route info:

--- Quote ---Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default SpiR 0.0.0.0 UG 0 0 0 br0
default SpiR 0.0.0.0 UG 0 0 0 wlan0
127.0.0.1 * 255.255.255.255 UH 0 0 0 lo
192.168.4.0 * 255.255.255.0 U 0 0 0 wlan0
192.168.4.0 * 255.255.255.0 U 0 0 0 br0
--- End quote ---

This table varies from the route table on the working Pi bridge. (SpiR is the router name)

I would be satisfied with this setup if the br0 stayed connected and remained that way.

Paul_123:
You cannot use the built in wifi.sh script. You must need to bring up the bridge first. You need to figure out how to use wpa_supplicant directly.

You will need a working wpa_supplicant.conf. Which should be as simple as this

--- Code: ---network={
ssid="MYSSID"
psk="passphrase"
}
--- End code ---

You can use wpa_passphrase to generate this too.

I found my SD card with the bridge setup. I modified the original wifi.sh script to do bridging.
If you use this,

bootlocal.sh looks like

--- Code: ---#!/bin/sh

# Start serial terminal
/usr/sbin/startserialtty &

# Set CPU frequency governor to ondemand (default is performance)
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

# Load modules
/sbin/modprobe i2c-dev

# Start openssh daemon
/usr/local/etc/init.d/openssh start

# ------ Put other system startup commands below this line

/home/tc/bridgewifi.sh -a

--- End code ---

I have attached the script.............. I have not re-tested this, but it was working under piCore 6.1

yeme:
Paul_123,

I will make the changes and let you know.

Thanks again for your attention to this for me!

yeme:
It works! I can now SSH via PuTTY also.

I placed your new script in /opt because I couldn't get it to persist in /home/tc - any problems with this location?

Paul_123:
It should persist in the /home/tc as long as you backup after putting the file there. But nothing wrong in /opt

Check the contents of /opt/.filetool.lst for the directories and files that get backed up
