Howto force scheduled DSL reconnects on Mikrotik routers

November 10, 2012

In my last blog post I have shown how to connect to a PPPoA provider with a Mikrotik router and get the public IP address on the router. I also mentioned that my provider has the bad habit of disconnecting every 8h. As thats not exactly 8h, it tends to wander, but I want at least always the same times. This blog post shows you how to do that if you want the same.

What the script basically does is to force a reconnect at a given time once a day. First we need to make sure that we’ve the correct time on the router. The simplest way to do that is following line:

/system ntp client set enabled=yes mode=unicast primary-ntp=

But you can only use an IP address there, if you want DNS names take a look hat this script. Also verify that you’ve configured the correct time zone with this command:

/system clock set time-zone-name=Europe/Vienna

Verify the current time with

[[email protected]] > /system clock print
time: 20:56:44
date: nov/04/2012
time-zone-name: Europe/Vienna
gmt-offset: +01:00
dst-active: no

Now we need to write the script, which we to in 2 steps. First we create the script ….

/system script add name=scriptForcedDslReconnect source=""

… than we open it in the editor and add the actual code

[[email protected]] > /system script edit 0
value-name: source

After this you get an editor and just copy and paste following lines:

/interface pptp-client set [find name="pptpDslInternet"] disabled=yes
/interface pptp-client set [find name="pptpDslInternet"] disabled=no
/log info message="pptpDslInternet forced reconnect. Done!"

and press CRTL-O. You can now check if all is correct with (everything should be colored in the script)

/system script print

Now we only need to add it to the scheduler

/system scheduler add name=schedularForcedDslReconnect start-time=00:40:00 interval=24h on-event=scriptForcedDslReconnect

And we’re done, it will disconnect always at 00:40, 8:40, 16:40 … as we wanted.

  1. should the interval be interval=8h instead of interval=24h ??

  2. Its enough to reset the schedule every 24h, the 8h happen alone and are not so precise so so a schedule would lengthen the down time. So I’m resetting the schedule every 24h to avoid it drifting.
