Folks,
I am a newbie, be gentle with me.
My Configuration is :-
DLink DSL-300+ ADSL modem Bering 1.2
My situation is as follows:-
The modem manages a pppoa connection with my ISP. Bering uses pump to communicate with the modem.
In general terms, this setup is working and I have full access to the internet from the machines on the internal network and from the LRP box.
The problem is two-fold in that my daemon.log file is growing at an alarming rate with messages from the pump daemon. The first reason that this is causing a problem is that each lease renewal is causing 25 to 30 lines to be written in the log. The second reason that this is causing a problem is that for some reason pump renewal is firing every 45 seconds or so.
What I would like to achieve is set a more realistic lease renewal period than 45 seconds and secondly reduce the number of lines that pump writes to the log when it does renew.
I have tried entering the command "pump -I eth0 -l 10" at the command line which I thought should set the lease time to 10 hours. It appears to have no effect.
My pump.conf and pump.shorewall files have not been changed from the standard files distributed with Bering 1.2
This has led me to conclude that the dlink adsl modem is controlling the lease time and I would need to reconfigure it to fix the first part of my problem. Is that a reasonable conclusion?
Yes, it is ... at least it is sort of right.
The DHCP server *always* controls the duration of the lease. A DHCP client can request a lease for a specific time -- that it what you are doing with pump -- but the server is authoritative with respect to lease lengths.
Whether you can change this behavior is unclear. One thing to notice is whether you keep getting the same address ... if you don't, it indicates the ISP is doing frequent address changes on purpose, perhaps to make it hard for you to run services on the Internet.
The one English data sheet I could find on your D-Link (at http://www.dlink.com.au/products/broadband/dsl300/ ... most info seems to be in French or German) makes no mention of it providing DHCP service, so how to reconfigure this setting is a bit of a mystery. Are you certain that the D-Link itself generates the lease info, and not a server at the ISP's end of your pppoa connection? (This was the "sort of" part above.)
