Midnight IP renewal

Hi!

We have an T-DSL Business ADSL line, that disconnects every 24 hours. Since we are using DynDNS services, we want that disconnect to happen at a time, when noone is using our webservices.

Is it possible to write a cron-job that reconnects at 3:00 for example?

Thanks,
Thorsten

What "disconnects"?
Your DHCP lease terminates?
pppoe?

Oh, I'm sorry! It's a PPPoE-DSL connection.

I want the script to disconnect the interface and reconnect it afterwards.

The provider really cuts of our line, so that we have to reconnect. But at this time we get an new IP, what's not that good when providing web services...

When the script disconnects our line, we can be sure, that there won't be an IP change for the next 24 hours. So during a normal work day, our IP we be the same all the time.

At the moment, we get a new IP at 14:00. To change this, I'd have to restart the firewall at night. I normally sleep at this time... [;)]

But I think, I'm not the only one with this problem, am I?

I'm pretty sure there was a post on this;
you add a call to a script in cron.

Do a search and if you don't find it repost here...

OK, now I found something:
https://community.sophos.com/products/unified-threat-management/astaroorg/f/51/t/21081

But where do I have to put the "killalll pppoe" command? Into the crontab or do I have to create a new script and put it into the cron.daily directory?

Best to put it in a script (though I suspect you can do the two commands using a bash && operator; but you might have to include the path to the bash interpreter...); here is a thread where they discuss the editing of cron entries:

IPSec with bothside dyn. IP´s

[I'm surprised there wasn't an example at the Astaro Hacker's website]

I´m surprised too ;-)

Maybe they do not know about it... so I will put the esentials of the thread into the Astaro Hacker´s website.

Can you post a link to that thread?

And just to put it right:

I'll then create a script called "crontab.dslreconnect" in /etc with this content:
0 3 * * * root /var/chroot-pppoe/etc/ppp/ip-down

Is this right for the PPPoE to reconnect at 3:00?

Thanks,
Thorsten

At least the "time" part though I do not know if the pppoe interface will come up automatically after the "down".

At least that's what you wrote on the ASL hacker page:
How can I reset my DSL/pppoe interface?
