Re: dhclient renew

I apologize if this is the wrong place to ask.

No probem at all.
Short: Does NM run dispatcher.d scripts if dhclient renews an IP? (NM

From NM point of view, there's no reason to do that, it's not a connection/connectivity change.

Our dns deletes dynamic entries if they have not been updated for 20
days or so.

So your DNS is updated by the client, not by the server. You could use cron for that, possibly. I don't think 
you can run specific scripts from dhclient when it's run with NetworkManager's action binary instead of 
dhclient-script, but let's wait for other responses. Therefore it looks like you want to get back the 
DHCP-based scripting capabilities with NetworkManager. It would be possible to modify the NM dhclient module.

We create and maintain this entries using a dispatcher
script in NM. This works fine for normal clients that are shutdown at
the end of the day/week. If the client runs for several weeks, it
regularly renews its dhcp lease (5 days), which I see in the
corresponding *.lease-file from dhclient. But I don't see any
activity concerning NM or our dispatcher script in the logs.
After the 20 days
have passed, the dns entry of the client just vanishes and I need to
manually disconnect and reconnect to retrigger the dispatcher script.

If it's 20 days, a cronjob checking for NM connection and acting upon it might be easier.
