How does the pinging script work on Qnap?

[aleksey_z]

Help me please.
TS239ProII+ & QTS 4.2.4
I try to run the pinging script for ping network devices (smartphone), but it does not work and I get in the log:

Code: Select all

grep: invalid option -- w
BusyBox v1.01 (2017.03.12-18:58+0000) multi-call binary

Usage: grep [-ihHnqvs] PATTERN [FILEs...]

Search for PATTERN in each FILE or standard input.

Options:
	-H	prefix output lines with filename where match was found
	-h	suppress the prefixing filename on output
	-i	ignore case distinctions
	-l	list names of files that match
	-n	print line number with output lines
	-q	be quiet. Returns 0 if result was found, 1 otherwise
	-v	select non-matching lines
	-s	suppress file open/read error messages

The script looks like this:

Code: Select all

#!/bin/sh
#set up new vars;
new_var=0
var1=android
var2=192.168.1.35
ddd=$(date +"%Y-%m-%d %H:%M:%S,%3N")
echo "datetime = $ddd"

echo "ipaddress to check is $var2"
status=`ping -qc 1 $var2 | grep -wi '[0-9][[:space:]]received'|awk -F, '{print $2}'|awk '{print $1}'`
echo "$var1 status is :$status";

# if status is ge 1 that means one of the ips responded to a ping.
# therefore value in pingsensor table should be set to 0;

   if [[ $status -gt 0 ]]; then
   echo "ping response received resetting $var1 status to 1"
   echo "1" > /share/MD0_DATA/.qpkg/OpenRemote/OpenRemote/facts/sensor_$var1
   else
    #write out a 0 in the android_sensor file
    echo "0" > /share/MD0_DATA/.qpkg/OpenRemote/OpenRemote/facts/sensor_$var1
   fi

ddd=$(date +"%Y-%m-%d %H:%M:%S,%3N")
echo "datetime = $ddd"
echo "**********************************************************"

On my second NAS Synology, this script works well for pinging my smartphone.

Thanks.

Looks like your old BusyBox 1.01 grep doesn't like that 'w' option.

So, you'll need to install GNU grep.

As I think you're now back on Optware (instead of Entware), try this:

Code: Select all

ipkg install grep

[aleksey_z]

Thanks for you quickly reply. Yes, I have install Optware.

Tomorrow a morning i try this.

Hi.

Which grep are you using?

Code: Select all

which grep

If your $PATH isn't set correctly, you won't run the new one by default.

To check the version:

Code: Select all

grep --version

Then try this one:

Code: Select all

/opt/bin/grep --version

So, you can now either manually specify /opt/bin/grep each time you need it, or you can prepend /opt/bin to your $PATH.

[aleksey_z]

I have little knowledge in Linux.
In the $PATH now like this: (after installing Optware-IPKG from package, I did not touch anything)

Where do I need to add /opt/bin/grep ?

[OneCD]

The third line from the bottom should be re-arranged so the /opt directories are at the front.

Like this:

Code: Select all

export PATH=/opt/bin:/opt/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/bin/X11:/usr/local/sbin:/usr/local/bin

[aleksey_z]

Not work. I add:

Code: Select all

export PATH=/opt/bin:/opt/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/bin/X11:/usr/local/sbin:/usr/local/bin:/var/lib/phpfiwa:/var/lib/phpfina:/var/lib/phptimeseries:/var/log

Please tell me where in the Qnap is being tuned a php open_basedir path.
I need to add:

Code: Select all

:/var/lib/phpfiwa:/var/lib/phpfina:/var/lib/phptimeseries:/var/log

In Synology it looks like this: screen

[aleksey_z]

Now, i change in Optware.sh

Code: Select all

# adding Ipkg apps into system path ...
	/bin/cat /etc/profile | /bin/grep "PATH" | /bin/grep "/opt/bin" 1>>/dev/null 2>>/dev/null
	[ $? -ne 0 ] && /bin/echo "export PATH=\$PATH":/opt/bin:/opt/sbin >> /etc/profile

after reboot i get this:

Code: Select all

[~] # echo $PATH
/bin:/sbin:/usr/bin:/usr/sbin:/usr/bin/X11:/usr/local/sbin:/usr/local/bin:/opt/bin:/opt/sbin:/usr/local/jre/bin

but in the /etc/profile only

Code: Select all

export PATH=$PATH:/opt/bin:/opt/sbin

in ping script log new argument

Code: Select all

Next step:

I change pinging script. Now the script looks like this:

Code: Select all

#!/bin/sh
#set up new vars;
new_var=0
var1=android
var2=192.168.1.35
ddd=$(date +"%Y-%m-%d %H:%M:%S,%3N")
echo "datetime = $ddd"

echo "ipaddress to check is $var2"
status=`ping -q c 1 $var2 | grep -vi '[0-9][[:space:]]received'|awk -F, '{print $2}'|awk '{print $1}'`
echo "$var1 status is :$status";

# if status is ge 1 that means one of the ips responded to a ping.
# therefore value in pingsensor table should be set to 0;

   if [[ $status -gt 0 ]]; then
   echo "ping response received resetting $var1 status to 1"
   echo "1" > /share/MD0_DATA/.qpkg/OpenRemote/OpenRemote/facts/sensor_$var1
   else
    #write out a 0 in the android_sensor file
    echo "0" > /share/MD0_DATA/.qpkg/OpenRemote/OpenRemote/facts/sensor_$var1
   fi

ddd=$(date +"%Y-%m-%d %H:%M:%S,%3N")
echo "datetime = $ddd"
echo "**********************************************************"

but in log only:

Code: Select all

ping: c: Unknown host
ping: c: Unknown host
ping: c: Unknown host
ping: c: Unknown host
ping: c: Unknown host

How fix its script?

[OneCD]

No sure where to start.

You're missing steps, you're rebooting without ensuring your files will be modified after reboot, you're showing extracts from files with no context.

When (re)setting variables like $PATH multiple times, the order becomes important. e.g.
PATH="/usr:/usr/bin"
PATH="/opt/bin:/opt/sbin:$PATH"

The third line from the bottom should be re-arranged so the /opt directories are at the front.

Like this:

Code: Select all

export PATH=/opt/bin:/opt/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/bin/X11:/usr/local/sbin:/usr/local/bin

Please note: /etc/profile is not persistent - changes made to it will be lost when you reboot - so you'll need to ensure that your /etc/profile is restored after reboot.

When you changed /etc/profile as I indicated above, did you logout and reconnect your SSH session?

Maybe the best thing to do (for now) is to set your $PATH manually. Run your script. Check that it works. If so, THEN modify /etc/profile.

So, at the shell prompt:

Code: Select all

export PATH="/opt/bin:/opt/sbin:$PATH"

Then try running your script.

[aleksey_z]

I performed at the shell prompt:

Code: Select all

[~] # export PATH="/opt/bin:/opt/sbin:$PATH"

Now I get:

Code: Select all

[~] # echo $PATH
/opt/bin:/opt/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/bin/X11:/usr/local/sbin:/usr/local/bin:/opt/bin:/opt/sbin:/usr/local/jre/bin

running script, but in log as before:

Code: Select all

ping: c: Unknown host

Maybe the script itself is not correct? But on the Synology worked well.

[OneCD]

running script, but in log as before:

Code: Select all

ping: c: Unknown host

Your ping command should specify '-c'. At the moment, it specifies 'c'

So, change it to this:

Code: Select all

status=`ping -q -c 1 $var2 | grep -vi '[0-9][[:space:]]received'|awk -F, '{print $2}'|awk '{print $1}'`
