Sometimes servers need to update its status or reboot by the condition to return its status to the best working environment to remove junk process or something like that. You can check that status by shell script. |
Below script makes server to reboot if ping does not work:
| Code Block |
|---|
#!/bin/bash
:Begin
ping -c 10 google.com
If %errorlevel% == 1 (
echo noreply
shutdown -r -t 0
)
If %errorlevel% == 0 (
GoTo :End
)
:End |
...
If you want to run above script at AsusWRT, you will need to modify the first line as following
| Code Block |
|---|
#!/bin/sh |
Below code works more accurately at AsusWRT
| Code Block | ||||
|---|---|---|---|---|

#!/bin/ash
if [ $( ping -c 1 google.com | grep ttl | wc -l ) -eq 0 ]
then
echo noreply
/sbin/reboot

echo "google.com is reachable"
