Mwan3 use command completely broken?

NETWORKING SOLUTIONS
1

RUTX11 on Firmware 7.10… only mobile connection (no wan cable).

I cannot use mwan3 use [cmd] at all. It appears to be an issue with the interface binding, because the commands work fine when not wrapped by mwan3.

Fails

root@r2-rnhq:~# mwan3 use mob1s1a1 ping -4 -c5 -W1 8.8.8.8

Hello,

Sorry for the late reply.

Please use mob1s1a1_4 instead of mob1s1a1.

Hope this helps!

Best regards,

Yes it helps! Thank you. I would say it’s confusing though that mwan3 interfaces or mwan3 status report the interface name as just mob1s1a1.

Hello,

It’s good to hear that it helped!

Unfortunately, there are no plans to update this command. However, if you want to use just mob1s1a1, you can modify the use() function and add two lines to the script:

  1. Open the file with vi /usr/sbin/mwan3/
  2. Press “i” to edit the file and scroll down to the use() function.
  3. Under network_get_device device $interface, add the following two lines:
`network_get_protocol proto $interface`
`[ "$proto" = "wwan" ] && network_get_device device ${interface}_4`
  • Press Esc, then type :wq to save the file and press Enter.
  • After these steps, you should be able to execute: mwan3 use mob1s1a1 ping -4 -c5 -W1 8.8.8.8.

Please let me know if there is anything else I can assist you with.

Best regards,

Not sure why you would say that. But, ok. As long as I know where the sharp edges are, I can avoid cutting myself. I won’t be editing this file on dozens of routers, seems a recipe for disaster…
