在openwrt路由中加入n2n，并在ubuntu里加入n2n服務，實現開機聯網互通互訪
1、openwrt的硬件環境：
將自己的WR703N刷入openwrt(這里需要修改FLASH芯片，換個8M的FLASH)；
刷機后，安裝openwrt，此教程網上一大堆，無需說明了，TELNET進入，并開啟SSH后，root登陸。
2、安裝n2n到openwrt中：
[email?protected]:~# opkg update
[email?protected]:~# cat /etc/opkg.conf
[email?protected]:~# opkg install n2n
運行上述命令即可安裝n2n。
3、修改n2n的配置文件：
[email?protected]:~# cat /etc/config/n2n
config edge
option ipaddr '10.10.100.191'
option supernode '106.186.30.16'
option port '9876'
option community 'leekwen'
option key 'leekwen'
option route '1'
4、修改n2n服務的啟動腳本：
[email?protected]:~# vi /etc/init.d/n2n
#!/bin/sh /etc/rc.common
# Copyright (C) 2008-2012 OpenWrt.org
START=90
start_instance() {
local cfg="$1"
config_get type "$cfg" TYPE
case "$type" in
edge)
config_get ipaddr "$cfg" 'ipaddr'
[ -n "$ipaddr" ] || return 1
config_get supernode "$cfg" 'supernode'
config_get port "$cfg" 'port'
config_get community "$cfg" 'community'
config_get key "$cfg" 'key'
config_get_bool route "$cfg" 'route' '0'
[ "$route" = "1" ] && args='-r'
service_start /usr/sbin/edge -f $args -a $ipaddr -c $community -k $key -l ${supernode}:${port} -M 1300
;;
supernode)
config_get port "$cfg" port
[ -n "$port" ] || return 1
service_start /usr/sbin/supernode -l $port
;;
esac
}
stop_instance() {
local cfg="$1"
config_get type "$cfg" TYPE
case "$type" in
edge)
service_stop /usr/sbin/edge
;;
supernode)
service_stop /usr/sbin/supernode
;;
esac
}
start() {
config_load 'n2n'
config_foreach start_instance 'edge'
config_foreach start_instance 'supernode'
}
stop() {
config_load 'n2n'
config_foreach stop_instance 'edge'
config_foreach stop_instance 'supernode'
}
5、將n2n加入openwrt系統啟動項：
[email?protected]:~# /etc/init.d/n2n enable
6、啟動openwrt中的n2n服務：
[email?protected]:~# /etc/init.d/n2n start
[email?protected]:~# ifconfig edge0
edge0 Link encap:Ethernet HWaddr 86:CC:1B:E9:1A:DC
inet addr:10.10.100.191 Bcast:10.10.100.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1300 Metric:1
RX packets:1117 errors:0 dropped:22 overruns:0 frame:0

collisions:0 txqueuelen:500
RX bytes:104415 (101.9 KiB) TX bytes:98732 (96.4 KiB)
7、互通測試：與我的手機端 n2n互ping下
[email?protected]:~# ping 10.10.100.103
PING 10.10.100.103 (10.10.100.103): 56 data bytes
64 bytes from 10.10.100.103: seq=0 ttl=64 time=31.738 ms

64 bytes from 10.10.100.103: seq=2 ttl=64 time=22.565 ms
64 bytes from 10.10.100.103: seq=3 ttl=64 time=40.063 ms
64 bytes from 10.10.100.103: seq=4 ttl=64 time=23.577 ms
^C

在ubuntu系統中增加n2n服務：
[email?protected]:~$ svn co https://svn.ntop.org/svn/ntop/trunk/n2n
[email?protected]:~$ cd n2n/
[email?protected]:~/n2n$ ls
n2n_v1 n2n_v2
[email?protected]:~/n2n$ cd n2n_v1/
[email?protected]:~/n2n/n2n_v1$ ls

[email?protected]:~/n2n/n2n_v1$ pwd
/home/Leekwen/n2n/n2n_v1
2、下載并編譯完畢后，編寫啟動服務文件n2n：
[email?protected]:~/n2n/n2n_v1$ vi n2n
#!/bin/bash
##Some Variable define here ##
PROG="edge"
n2n_IP="10.10.100.103"
n2n_cname="leekwen"
n2n_pass="leekwen"
SNODE_Host="106.186.30.16"
SNODE_Port="9876"
LOGS="/var/log/$PROG.log"
PROG_PATH="/home/leekwen/n2n/n2n_v1" # edge binary put on here for testing this script, Not Needed if the system binary.
PROG_ARGS="-f -d edge0 -a $n2n_IP -c $n2n_cname -k $n2n_pass -l $SNODE_Host:$SNODE_Port -M 1300"
PID_PATH="/var/run"
RETVAL=0
start() {
pid=`ps ax | grep $PROG | grep -v "grep" | awk '{print $1}'`
if [ ! -z "$pid" ]; then
## Program is running, exit with error.
echo "Error! $PROG is currently running!" 1>&2
exit 1
else
## Change from /dev/null to something like /var/log/$PROG if you want to save output.
$PROG_PATH/$PROG $PROG_ARGS 2>&1 > $LOGS &
echo "$PROG started"
echo $pid > "$PID_PATH/$PROG.pid"
fi
RETVAL=$?
if [ $RETVAL -eq 0 ]; then
echo -e "\\033[60G\c"
echo -e "[ \\033[1;32m\c"
echo -e "OK\c"
echo -e "\\033[0;39m\c"
echo " ]"
else
echo -e "\\033[60G\c"
echo -e "[ \\033[1;31m\c"
echo -e "FAILED\c"
echo -e "\\033[0;39m\c"
echo " ]"
fi
return $RETVAL
}
stop() {
pid=`ps ax | grep $PROG | grep -v "grep"| awk '{print $1}'`
if [ ! -z "$pid" ]; then
## Program is running, so stop it
kill $pid
rm -f "$PID_PATH/$PROG.pid"
echo "$PROG stopped"
else
## Program is not running, exit with error.
echo "Error! $PROG not started!" 1>&2
exit 1
fi
RETVAL=$?
if [ $RETVAL -eq 0 ]; then
echo -e "\\033[60G\c"
echo -e "[ \\033[1;32m\c"
echo -e "OK\c"
echo -e "\\033[0;39m\c"
echo " ]"
else
echo -e "\\033[60G\c"
echo -e "[ \\033[1;31m\c"
echo -e "FAILED\c"
echo -e "\\033[0;39m\c"
echo " ]"
fi
return $RETVAL
}
## Check to see if we are running as root first.
## Found at http://www.cyberciti.biz/tips/shell-root-user-check-script.html
if [ "$(id -u)" != "0" ]; then
echo "This script must be run as root, you can use sudo command to run it." 1>&2
exit 1
fi
case "$1" in
start)
start
exit 0
;;
stop)
stop
exit 0
;;
reload|restart|force-reload)
stop
start
exit 0
;;
**)
echo "Usage: $0 {start|stop|reload}" 1>&2
exit 1
;;
esac
3、增加可執行權限，移動n2n服務到/etc/init.d/，并更新rc.d
[email?protected]:~/n2n/n2n_v1$ chmod 755 n2n
[email?protected]:~/n2n/n2n_v1$ sudo mv n2n /etc/init.d/
[email?protected]:~/n2n/n2n_v1$ sudo update-rc.d n2n defaults
4、對n2n服務進行測試：
[email?protected]:~/n2n/n2n_v1$ /etc/init.d/n2n start
[email?protected]:~/n2n/n2n_v1$ ifconfig edge0
[email?protected]:~/n2n/n2n_v1$ /etc/init.d/n2n stop
[email?protected]:~/n2n/n2n_v1$ ifconfig edge0
[email?protected]:~/n2n/n2n_v1$ /etc/init.d/n2n restart
[email?protected]:~/n2n/n2n_v1$ ifconfig edge0
5、對n2n服務進行Ping連通性測試：
[email?protected]:~/n2n/n2n_v1$ ping 10.10.100.103
PING 10.10.100.103 (10.10.100.103): 56 data bytes
64 bytes from 10.10.100.103: seq=0 ttl=64 time=11.738 ms
64 bytes from 10.10.100.103: seq=1 ttl=64 time=15.347 ms
64 bytes from 10.10.100.103: seq=2 ttl=64 time=12.565 ms
64 bytes from 10.10.100.103: seq=3 ttl=64 time=10.063 ms
64 bytes from 10.10.100.103: seq=4 ttl=64 time=13.577 ms
^C
--- 10.10.100.103 ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 10.063/12.838/15.347 ms
到此客戶端的已經安裝成功，在網絡連接的情況下，每次重啟ubuntu及openwrt路由后，他們都會自動連接上supernode節點，以構建一個p2p的網絡。
