openvpn开机rc_startup运行后自动退出 #76

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
請描述一下您進行怎樣的操作之後碰到了問題：
openvpn用rc_startup启动
rc_startup=date -s "2010-07-29 12:00:00"; openvpn --config 
/jffs/openvpn/openvpn.conf --daemon &

问题：dd-wrt启动过程中，telnet上去看到openvpn是自动启动并正�
��添加路由。
但启动完成后，openvpn就消失了

這個版本實在太老了，建議使用至少14xxx的版本。

另外你的rc_startup

rc_startup=date -s "2010-07-29 12:00:00"; openvpn --config 
/jffs/openvpn/openvpn.conf --daemon & 

這樣寫可能會有問題，請照這份文件
http://code.google.com/p/autoddvpn/wiki/OpenVPNManualStartUP
ssh進去DDWRT之後
nvram set rc_startup='date -s "2010-07-29 12:00:00"; openvpn --config 
/jffs/openvpn/openvpn.conf --daemon'

用這方式來設置rc_startup內容，最後不需要&符號。

這是我看到可能的原因，供你參考。

下--daemon的時候就會自動丟到background了， 不需要再&了。FYI

你好！刚才把dd-wrt更新到最新版本
DD-WRT v24-sp2 vpn (c) 2011 NewMedia-NET GmbH
Release: 05/17/11 (SVN revision: 17084)

可能openvpn版本太新，原配置有点问题
openvpn --config /jffs/openvpn/openvpn.conf --daemon

/jffs/openvpn/openvpn.conf 最後一行加上

script-security 3 system

即可

总结一下：
1.升级到最新版dd-wrt
2.openvpn.conf 加上 script-security 3 system

dd-wrt启动后能自动运行openvpn，搞定，thanks！
