一.在 \fmk\rootfs\etc\config 目录下新建文件 nocat_liht.sh ：
#!/bin/sh
status=`/bin/ps | /bin/grep splashd | /bin/grep -v grep | /bin/wc -l`
#取得nocat状态，必须为1，不能是0，也不能是2
if [ $status != 1 ];
then
/usr/sbin/splashd
# date >> /tmp/nocat.log #记录出错时间
# echo "liht_nocat auto restarted" >> /tmp/nocat.log
else
exit
fi
注意：需要管理员登陆linux才能修改rootfs目录，保存后记得修改文件属性为可执行。
二. 修改 \fmk\rootfs\etc\config 目录下的nocat.startup文件，添加如下内容：
if [ "$(nvram get NC_enable)" = "1" ]; then
* * * * * root /etc/config/nocat_liht.sh
fi
意思是，如果使用了nocat，就每分钟运行一次脚本。
nocat.sh
Code:
#!/bin/sh
X=1
Y=status
while [ $X -eq 1 ]
do
sleep 1000
cd /tmp
sleep 7
webup=`ls status`
if [ "$Y" != "$webup" ]; then
killall wget
sleep 5
killall splashd
echo "nocat restarted" >> nocat.log
sleep 20
splashd
sleep 5
else
# echo "status deleted" >> nocat.log
rm /tmp/status
fi
done
192.168.2.241 is the ip of the dd-wrt on the lan side
this check if the status nocat page is working otherwise restarts nocat. The killall comand could be a reboot command if the proccess cannot be killed (depending on the enviroment may be better...).
I put the script in the startup.
Code:
wget -P/tmp http://anyserver/nocat.sh
chmod +x /tmp/nocat.sh
/tmp/nocat.sh &
where anyserver is a webserver containing nocat.sh, and accesible for the router
This work for me, every 24-48 hours nocat need to be restarted. Sometimes nocat depending on global configuration may be too unstable, and the script does not help very much.
进入 DD-WRT 网页管理界面，Administration -> Commands，贴入如下脚本Save Startup：
mkdir /tmp/myscripts
/bin/echo ‘#!/bin/sh
status=`/bin/ps | /bin/grep splashd | /bin/grep -v grep | /bin/wc -l`
#echo $status
if [ $status = 0 ];
then
/usr/sbin/splashd >> /tmp/nocat.log 2>&1 &
else
exit
fi’ >> /tmp/myscripts/monitor_splash
/bin/chmod +x /tmp/myscripts/monitor_splash
/bin/echo ‘ * * * * * root /tmp/myscripts/monitor_splash’ >> /tmp/crontab
# restart cron daemon
stopservice cron && startservice cron
