Linux bandwidth monitor with per-device tracking

wrtbwmon

Modified from https://code.google.com/p/wrtbwmon/.

Testers needed for IPv6 support

Experimental release: https://github.com/pyrovski/wrtbwmon/releases/tag/0.37_ipv6

Features

• "User" column has mouseover text containing MAC and IP addresses
• "First seen" and "Total" columns in usage table
• Monitoring of locally generated traffic on a per-interface basis
• remove function to delete iptables rules

What does it do?

wrtbwmon was designed to track bandwidth consumption on home routers. It accomplishes this with iptables rules, which means you don't need to run an extra process just to track bandwidth. wrtbwmon conveniently tracks bandwidth consumption on a per-IP address basis, so you can easily determine which user/device is the culprit.

Here is an example usage table:

How do I use it?

• Install: Download and install ipk from the releases page
• Setup: wrtbwmon setup
• Update table: wrtbwmon update /tmp/usage.db (you can place the data table anywhere)
• Create html page: wrtbwmon publish /tmp/usage.db /tmp/usage.htm
• Dump table to terminal: wrtbwmon dump /tmp/usage.db
• Remove: wrtbwmon remove

Installation options

• Install ipk
  • e.g.,:
    • cd /tmp
    • HTTPS: curl -LO https://github.com/pyrovski/wrtbwmon/releases/download/0.36/wrtbwmon_0.36_all.ipk
    • HTTP: you're on your own :( Busybox wget usually doesn't have SSL support.
    • OpenWrt: opkg install /tmp/wrtbwmon_0.36_all.ipk
• Install deb from the releases page
• Or, if you don't want to use an ipk or a deb:
  • cd /tmp
  • HTTPS: curl -L https://github.com/pyrovski/wrtbwmon/archive/0.36.tar.gz | tar xvz
  • cd wrtbwmon-0.36
  • ./install.sh wrtbwmon readDB.awk usage.htm1 usage.htm2 wrtbwmon
    • Currently, this depends on the install program. OpenWrt chose to provide this as the "coreutils-install" package.
• Or, if you have make, just make install as root after cloning/unpacking.

Configuring the published table

• wrtbwmon checks a few files for MAC -> name maps:
  • 4th argument to wrtbwmon publish <DB> <userDB>
  • /tmp/dhcp.leases
  • /tmp/dnsmasq.conf
  • /etc/dnsmasq.conf
  • /etc/hosts
• If all of the above do not yield a match, the script will optionally perform a reverse DNS lookup directed at the DNS server specified in the DNS variable. If DNS is blank or unset, the script will not perform such lookups.

Regular updates

• Add the following to root's crontab:

    # adapt PATH to your needs
    PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
  
    * * * * * <script location> update /tmp/usage.db
    0 * * * * <script location> publish /tmp/usage.db /tmp/usage.htm
  

• On OpenWRT you need to enable cron as it is disabled by default:

    /etc/init.d/cron start
    /etc/init.d/cron enable
  

• Enable web serving of the generated page (optional) This varies by environment, but for lighttpd:

    ln -s /tmp/usage.htm /var/www/html/
  

Remove iptables rules

• wrtbwmon remove

wrtbwmon's Issues

Search for hostnames in the `/etc/config/dhcp` file as well

Hey @pyrovski it's me again!

I think it would be great if wrtbwmon could also parse the /etc/config/dhcp file to search for hostnames.
The great thing about this file is that when the user assigns a static IP from the DHCP settings in his router the following entry appears in the file:

config host
	option name 'BradleyDesktop'
	option dns '1'
	option mac '1c:1b:0d:e5:60:f1'
	option ip '192.168.1.69'
	option leasetime 'infinite'

also, when the user sets a custom hostname from the Hostnames page the following entry appears:

config domain
	option name 'TestDeviceName'
	option ip '192.168.1.167'

What do you think? Is this PR worthy?

iptables v1.4.21: host/network `eth1' not found when trying to use old usage.db

Hi - I have updated my wrtbwmon script with rev 208c412.

I'm not sure which version I used before but I remember I installed the previous version on 17 JAN).

The new version works but I have problems getting it to work with my old usage.db.

When I tried an update, I get these errors:
root@OpenWrt:~# /transfer/wrtbwmon# wrtbwmon.sh update /tmp/usage.db
iptables v1.4.21: host/network eth1' not found Tryiptables -h' or 'iptables --help' for more information.
iptables v1.4.21: host/network eth1' not found Tryiptables -h' or 'iptables --help' for more information.

If I start with a fresh usage.db then all works:

root@OpenWrt:# /transfer/wrtbwmon# rm /tmp/usage.db
root@OpenWrt:# /transfer/wrtbwmon# wrtbwmon.sh setup /tmp/usage.db
root@OpenWrt:# /transfer/wrtbwmon# wrtbwmon.sh update /tmp/usage.db
root@OpenWrt:#

But when I restore the old usage.db and try an update, then it fails again:

root@OpenWrt:# /transfer/wrtbwmon# cp /tmp/usage.db-bak /tmp/usage.db
root@OpenWrt:# /transfer/wrtbwmon# wrtbwmon.sh update /tmp/usage.db

iptables v1.4.21: host/network eth1' not found Tryiptables -h' or 'iptables --help' for more information.

Has there been a change in the DB layout since JAN? If not, how can I merge the old and new usage.db?

Doesn't work :(

Any ideas why it doesn't work on OpenWrt?

interface improvements?

hey, great to know you have continued on wrtbwmon script. I really don't know why something like this isn't built in OpenWRT! really!

1. I've added IP column next to User column following your code. I didn't find any reason to not showing it. I haven't taken a look at the "awk" branch although, so I stopped from pulling a request to master on that little change.

2. are you planning to improve the design a bit? bootstrap? maybe integrate with luci interface as luci-app-wrtbwmon?

3. if I do wrtbwmon publish /tmp/usage.db /tmp/usage.htm every minute instead of an hour inside my cronjob, would it be resource consuming? would it be possible to only publish when accessing the html file? and maybe include an autorefresh feature?

sorry, lot of questions :)

Interface messed up in 18.06

The web interface inside Luci is messed up a bit, in 18.06 version.

WAN Port MAC Address showing up multiple times in Table

I was recently asked to switch my internet setup from PPPoE to DHCP by my ISP and after that my wrtbwmon table has become overrun with entries for the WAN interface like this: http://img.mystphy.sx/ss%20%282016-12-16%20at%2006.22.39%29.png

Is there any solution for this? Can wrtbwmon just ignore entries for a certain MAC address?

postinst is not included in ipk

The postinst file is not included in the control archive of the ipk package. It sets up a useful cron job for updating the database and the web page.

Also, on openwrt there is no wrtbwmon user, so either one needs to be created or the cron job needs to be set up in /etc/cronjobs/root instead of /etc/cronjobs/wrtbwmon.

I'm getting 0 download kbps using OpenWrt Chaos Calmer 15.05

need help, thanks!

Why Network Usage always show 0 B?

Repeated rules in iptables

Hi
been using this utility for a while (actually also forked it as I'm creating a version that sends all the data to a Pi or other Linux device for storing in a sqlite database), and have noticed a small issue. The RRDIPT_FORWARD rules have many repeated entries.
As I understand it the newRule(arp_ip) function will add rules to this section when it detects an IP address that it thinks isn't in there already. I think the issue is with this section of code:
# for hosts without rules
for(host in hosts){
if(!inInterfaces(host))
newRule(host)
}

If I understand this code correctly, if the IP exists in the usage.db but NOT in the arps table, then the specific host won't be removed from the hosts array; then when we get to this section of code, it treats it like a host that hasn't been entered in the RRDIPT_FORWARD ruleset and adds it again.

I've got a few ideas on how to fix this, but don't want to break anything (not knowing the full intent of this code section.)

Power cut

I live in a place where there is a lot of power cut.
So I've setup the database on a USB stick. But it looks like, because of the cut, the file became empty (0 bytes).
So I'm thinking of 2 improvements : during an update, make backups. At least 3, or maybe configurable. Example : usage.db.3 would be deleted, usage.db.2 renamed usage.db.3, usage.db.1 renamed usage.db.2, usage.db copied usage.db.1 and then finally usage.db could be updated.

Then at setup, do something like if usage.db is valid, use it. If not delete it, rename usage.db.1 to usage.db and try it, and so forth if usage.db.1 is not valid.

Now, how to know if a file is valid ? Maybe just add in the file a last line containing FileSize=xxx. If, when opening the usage.db (for setup or update), you can't find FileSize, or FileSize doesn't match, it's invalid.

Food for though, let me know what you think. Thanks.

IP not expanded correctly

Hi,

Thanks for the wonderful utility! It's certainly very useful! I am running the latest release of openwrt, and I see this kind of output: (I've obfuscated some personal details)

How to build into openwrt?

Dear Pyrovski,

To build wrtbwmon packages into openwrt firmware, I added the following line to the feeds.conf in the OpenWrt buildroot:

src-git wrtbwmon https://github.com/pyrovski/wrtbwmon.git

Then I update and install feeds.

But when I run "make menuconfig", I cannot see any wrtbwmon package to be selected. If I run "make V=s", it generate a firmware, but without wrtbwmon.

Is it possible to build wrtbwmon package to be included into the openwrt firmware?

Thanks a lot for any idea!

Add option to keep track monthly

I'd like to see a option to keep track monthly. This would help me immensely since my ISP, Comcast, tracks my data usage and threatens to cancel after 1TB of usage. I use this on my OpenWRT router along side https://github.com/Kiougar/luci-wrtbwmon

Related to this issue Kiougar/luci-wrtbwmon#22

OpenWrt 22.03 migration from iptables to the nftables

Hi,

I am currently using openwrt 21 and looking to upgrade to 22 but looks like this package is based on iptables .

Is it possible to have a compatible version for nftables?

Thanks.

The OpenWrt 22.03 series focuses on the migration from iptables based firewall3 to the nftables based firewall4.

Usage is too low compared to the real usage

in very short, after I installed wrtbwmon as well as the luci addon, I tried it by mass downloading stuff just to see how it would react, weirdly enough I could not get more than about 300KB/s download speed to show and a total download of 3MB was noted which is inaccurate considering I've been downloading about 1GB of stuff during my tests at a speed of around 2MBps.

I off course kept the page running during the whole process to keep an eye out, I also noted that it sometimes would even go as far as to say I had 0 B/s on each refresh while I was downloading.

Not found in openwrt repo

Can you add this to OpenWRT repo?

Quota/bandwidth limiting support

With per-IP rules in place, it should be simple to add tc classes for bandwidth limiting.

Please upstream this

This along with https://github.com/Kiougar/luci-wrtbwmon is absolutely brilliant.
Please upstream this?

Starting 19.x onwards, you want to be aware of openwrt/luci@a13748d#diff-ce5e8587ed4408d7875a66815aa383c7L859

Example: get_wannet() has been replaced with get_wan_networks() that returns a list of upstream interfaces.

presumptions

First thanks for updating wrtbwmon script, it worked for me once but now it is giving me lots of errors.
I looked at your code and one thing I don't like is that you have make is to take too much presumtions and don't leave choice to users.

For example I would like to track wifi interface which is in network called also wifi, with your current script I can't do that without heavily modifying whole code.

Original script has nice variables that let users choose which interface to monitor.

Will you consider going back more to original authors idea of being more flexible?

Thanks!

Problem with WAN Detection OPENWRT

Thanks for updating this script,
Compared to the Master branch, the AWK branch seems to have a problem with the way it writes out the detected WAN into the DB file.
For debugging purposes i just ran the Master branch and then the AWK branch with the following
MASTER
(WAN),NA,eth1,46508,22835,0,0,69343,04-05-2015_08:53:33,04-05-2015_08:53:34

AWK
eth1,NA,eth1,32,1672,,,1704,04-05-2015_09:47:25,04-05-2015_09:47:25

The extra three columns result in the quotes being in the wrong placed in the array when published, and the entire table then fails to load.
Array in Javascript in AWK generated HTML
new Array("eth1",
32.000000,1672,1704,04-05-2015_09:47:25,04-05-2015_09:47:25,"",""),

Hope this helps

cheers

wrtbwmon may reduce throughput on high-speed connections

Even though the kernel does all the accounting, having many iptables rules can slow down a home router, especially if its already nearing its NAT throughput limit.

I ran "wrtbwmon remove" but it seems it's still installed

In root@LEDE: I ran wrtbwmon remove

Then I ran wrtbwmon setup. But I got

ERROR: Missing argument 2 (database file)

What's wrong?

If wrtbwmon has been removed, I expect it to say

-ash: weo: not found

ipv6 is not supported

There is no ipv6 support.

Not seeing names in usage.htm

I've generated a users.txt file and am using it when publishing, but there's no change to the html page. What should I be seeing? Is my users format is messed up?

## /opt/wrtbwmon/users.txt
00:AA:11:BB:22:BC,black-cisco-router
74:AA:11:BB:22:10,xps

10:AA:11:BB:22:4E,printer

/opt/sbin/wrtbwmon publish /tmp/usage.db /opt/share/www/custom/usage.htm /opt/wrtbwmon/users.txt

(As a general note, maybe instructions should refer to machine names as well as or instead of users, since the lookup is by ip and some devices have multiple users.)

eth1 wan interface is backwards?

For eth1, which is actually my wan interface shows download 147mb and upload 4.451GB. This is actually backwards. 4.451GB has been downloaded to the router via transmission, not uploaded to the Internet.
