thanks for the reply, sounds very logical
If you issue
Code:
runner disable
fc disable
before running the script, hopefully the statistics are as expected?

You can then manually explicitly re-enable HW Acceleration or simply reboot.
 
So this runs on stock firmware without the need for QOS or Parental Controls to be enabled?
 
I am trying to get this running on my RT-AC68U. I am getting these errors. Can someone point me in the right direction?

Sorry, no idea. It works for me, but then I have a different router. What firmware version are you using?

I suggest you reset everything and try it again without any IP addresses.
Code:
./QuotaMonitor.sh resetdel
./QuotaMonitor.sh init
./QuotaMonitor.sh monitor
 
Thanks. That was helpful. I went back and just added one IP address and then ran monitor. The monitor ran this time, but for some reason it shows the IP address of my DNS server rather than the IP address I added. I think that is why the "duplicate hostnames" were detected; it just added my DNS IP (and hostname) multiple times.
 
It sounds like it's glitching on an nslookup. Do you have any Entware packages or addon scripts installed (other than this script)?

No. I was using the WAN failover scripts, but reformatted JFFS and started over to see if it would fix this issue...but it didn't.
 
Are you using any strange characters in your host names? QoS enabled?

Try running it with the verbose option:

Does an "_" count as a strange character? The one I am trying to add is shown with client name of "RZYHGCJ00001973_JIDU6001" in the GUI.

When I use the verbose option, I see this:

Looks about right, but even here it is somehow convinced that the IP address is "dns". Also, when I get it into a blocking state, it blocks DNS rather than the IP:

Is it possible there is a dependency related to the DNS settings in the GUI?

Also, on the topic of special characters, I notice that when I do an nslookup it showns 8.8.8.8 as "dns.google". Perhaps the "." is causing an issue. Not sure how I change the configuration to use a different name, though.

That is correct. 8.8.8.8 is dns.google.
 
What do you get from these commands (post the output within a CODE block):
Code:
nslookup RZYHGCJ00001973_JIDU6001

nslookup 192.168.2.44
 
I think I've just realised what the problem is...

Log into the router and go to Tools - Other Settings. Change Wan: Use local caching DNS server as system resolver to Yes.
 
I may try your solution to see if it makes a different (I doubt it, given what is below), but I made a change to the script that fixes it on my system.

I changed this line:
IP_RANGE=$(nslookup $1 | grep "Address" | grep -v localhost | cut -d" " -f4)

to this:
IP_RANGE=$(nslookup $1 | grep "Address" | tail -n 1 | grep -v localhost | cut -d" " -f4)


The reason is that nslookup returns something that looks like this on my system:

admin@RT-AC68U-5E80:/jffs/scripts# nslookup 192.168.2.44
Server: 8.8.8.8
Address 1: 8.8.8.8 dns.google

Name: 192.168.2.44
Address 1: 192.168.2.44 myrouter


So without adding the "tail -n 1", that line from the script was returning:
dns.google
myrouter

As such...it kept picking out the "dns" and getting the wrong result. By adding the "tail" it just takes the last line returned.
 
I believe the problem occurs when the script tries to determine the IP address from the hostname. Without changing that GUI option, and if you haven't created a DHCP reservation for the host, it sends the request to the WAN DNS server which has no knowledge of a host called "RZYHGCJ00001973_JIDU6001".

Code:
# nslookup RZYHGCJ00001973_JIDU6001
Server:    8.8.8.8
Address 1: 8.8.8.8 dns.google

nslookup: can't resolve 'RZYHGCJ00001973_JIDU6001'

The script appears to be expecting you to be using localhost for your DNS (which was the default setting back in 2018), which is why it's grep'ing out that localhost line:
Code:
# nslookup zen
Server:    127.0.0.1
Address 1: 127.0.0.1 localhost.localdomain

Name:      zen
Address 1: 192.168.1.49 zen.home.lan
