Junos OS

Hello,

 

I have a problem with a vpn between several j-series routers. The devices are connected to the internet via dsl and the provider forces a disconnect every 24 hours.

When the forced disconnect happens during the working hours there are sometimes problems with clients reconnecting to sessions on the server.

So I want to schedule a disconnect with a script every day at 3:00 am.

How can I do this?

 

Any solution would be nice,

 

Best regards,

 

Michael

Is it possible to achieve what you want manually through CLI commands or configuration changes?  If so then it would be possible to automate those same commands through an event script at a certain time of day.  What commands would you use to disconnect them?

When I disconnect the connection I enter the following commands:

 

edit interfaces pp0.0

set disable

commit

 

To activate the connection again I enter the following commands:

 

edit interfaces pp0.0

delete disable

commit

 

Would it be possible to do this steps in two op scripts where the first is started at 3:00 am and the second is started at 3:01 am?

Try the attached script.  It disables pp0.0 at 3:00am, pauses for a minute, and then removes the disable statement.  The pause length can be lowered by decreasing the second count within jcs:sleep() if you decide that a minute is too long.

 

To enable first copy it to your event script directory:

/var/db/scripts/event

 

Then enable it:

set event-options event-script file bounce-pp.slax

 

Minimum JUNOS version is 9.3.

 

You can test it by altering the time to right before 3:00am and then reloading the event scripts (so they adjust to the new time):

 

 jnpr@R2D2-RE0> set date 200907090259.50
Thu Jul  9 02:59:50 PDT 2009

jnpr@R2D2-RE0> request system scripts event-scripts reload
Event scripts loaded

Hello,

 

I have updated the devices to the requested JunOS version and installed the script. Everything is working fine.

 

Thanks for the quick and easy solution!
