#5--Installing osniffer!

1 make the FIrmware and SDK

!!! attention : select libpcap NOT libcap

cd /home/workplace/
cd WRTnodeSDK140824/
make menuconfig
#[*] Build the OpenWrt SDK
# Libraries  ---> <*> libpcap............ Low-level packet capture library  --->
make 

2 Flush our Firmware

• connect to wrtnode via wifi
• visit 192.168.8.1
• login
• System -->Backup/Flash Firmware
• Flash new firmware image --choose the /workplace/WRTnodeSDK140824/bin/ramips/openwrt-ramips-mt7620n-wrtnode-squashfs-sysupgrade.bin
• Flash image
• Flash Firmware - Verify --> Proceed
• Wait for about 5 minutes

3 Compile for ipk

cd /workplace/WRTnodeSDK140824/bin/ramips/
tar -xf OpenWrt-SDK-ramips-for-linux-x86_64-gcc-4.8-linaro_uClibc-0.9.33.2.tar.bz2
cd OpenWrt-SDK-ramips-for-linux-x86_64-gcc-4.8-linaro_uClibc-0.9.33.2/package
git clone -b master --single-branch https://github.com/cooljiansir/osniffer.git
cd ..
make
cd bin/ramips/packages 
scp OpenWrtSniffer_1_ramips_24kec.ipk root@192.168.8.1:/usr/bin/
ssh root@192.168.8.1
cd /usr/bin
opkg install OpenWrtSniffer_1_ramips_24kec.ipk 

4 Copy the web files

git clone -b web2 --single-branch https://github.com/cooljiansir/osniffer.git
cd osniffer
scp -r * root@192.168.8.1:/webroot/
ssh root@192.168.8.1
vi /etc/config/uhttpd 
#check if there are lines:,if not add them
config uhttpd web
        list listen_http 0.0.0.0:81
        option home /webroot/
/etc/init.d/uhttpd restart

Now visit 192.168.8.1:81 !

• Capture --> Interfaces....
• select any
• Capture --> Capture Filters
• enter 'arp ' in the first input there is a blank after arp
• click set
• Capture --> Go
• click start
• visit 192.168.8.12 and there are arp packets captured

The problem....em....I've also met it before.
/webroot/cgi-bin/snifferd doesn't start ,see '7b1d064'

It's a bug when first time visit 192.168.8.1:81 and no packets before,I've fixed it 082acf9

Solution : Just use the clone master0.1 and web0.1

I feel sorry about that,the master0.1 branch and web0.1 branch is the release version 0.1,and it's OK

When I install the osniffer I find I can use start in the go only once.There is no response when I click it the second time after click the stop.And I cannot visit the 192.168.8.12.

[cooljiansir]

The aim of visiting 192.168.8.12 is to make arp packets. 192.168.12 is not accessible.

[J1nwenWang]

I get it,what will we do the next step？Is there any development documents?

[cooljiansir]

Nice,I'll explain how the app works later,and discuss our plans.
