WAN是dhcp的情況，用一陣子之後會突然間路由表被清空，還不�
��道原因，這時必須手動執行
rc_firewall才能解決。

需要想一個辦法。

剛剛又出現路由表被清空的情況
癥狀是：所有外部網路都突然連不上，只有內部網路還正常

SSH一進去以後，先檢查路由表，發現默認的vpn gw果然被清空
不管怎麼添加vpn gateway，路由器都不理
接著我加入192.168.1.1為默認（這時候可以加入）
接著刪除192.168.1.1，再加入vpn gw，此時才正常

下面是完整的SSH操作過程log

看到了，其實都是兩個gw跳掉，但是其他路由表沒有跳掉對吧
？
我在思考監控邏輯要怎麼設計，是default 
gw沒了就自動補回來就好？

Original comment by pahud...@gmail.com on 5 Jun 2010 at 2:05

GoogleCodeExporter commented 9 years ago 
嗯，只有default gw消失了，其他的還在

比較奇怪的是，我是先嘗試補VPN gw，但是補不上
要先補上192.168.1.1為default gw，再刪除
才可以補上VPN gw

我已經寫好CRON script, 
正在自己測試中，如果今明兩天沒甚麼問題就丟出來給大家��
�看看。

這個CRON會有智慧型的自動修復功能。

附上CRON的設置方式，check.sh可以在這邊找到
http://autoddvpn.googlecode.com/svn/trunk/cron/check.sh
請自行抓下之後scp到/tmp/下面即可。

我先這樣運行幾天看看，可以的話我再包裝一下。

CRON那邊請先用這樣寫法

* * * * * root /bin/sh /tmp/check.sh >> /tmp/last_check.log
使用>>的話會把log append到/tmp/last_check.log, 
而不會抹掉之前的。

等過一段時間之後可以scp出來Mac/Linux, 然後用這個指令來查詢

macbook:tmp macbook$ grep -c adding last_check.log 
4  
(表示四次自動修復)
macbook:tmp macbook$ grep -B7 adding last_check.log  > xxx.log
(把自動修復的記錄寫入新的xxx.log)

上周测试已经OK。刚刚封装好脚本，再最后测试一下。

目前rc_firewall只要设置这样即可

test -f /tmp/rc_fw_done || ( echo $$ >> /tmp/rc_fw_done; test $$ -eq $(head -n1 
/tmp/rc_fw_done) && cd /tmp; sleep 10; wget 
http://autoddvpn.googlecode.com/svn/trunk/run-dev.sh -O /tmp/run-dev.sh && 
/bin/sh run-dev.sh )

不用另外在web  UI上面打开cron, 脚本会自行打开cron监控。

log大约是这样
