Title: Almost 100% CPU use with DHCP issue
Post by: barn on September 16, 2004, 10:56:53 PM
This is a problem very similar to a posting made by Trekow, but slightly different.

My network is setup like this

ADSL router > SMEServer > clients

On the external side the SME server receives an (dhcp) ip number from the router and on the internal network the SME is a dhcp server, the problem is just my server went crazy, CPU used 80-90% all the time because S16adjust-masq, S55email-conf, S80pptpd-conf, S55mailfront-co, S47proftpd-conf, S50conf-securit, S85update-dns always was restarting.

When i look in the log I see:
 
Sep 17 00:25:31 esmith dhcpcd[7111]: broadcasting DHCP_REQUEST for 10.0.0.9
Sep 17 00:25:31 esmith dhcpcd[7111]: broadcastAddr option is missing in DHCP server response. Assuming 10.0.0.255
Sep 17 00:25:31 esmith dhcpcd[7111]: DHCP_ACK received from  (10.0.0.2)
Sep 17 00:25:31 esmith dhcpcd[7111]: dhcpConfig: ioctl SIOCADDRT: File exists
Sep 17 00:25:32 esmith dhcpcd[7111]: infinite IP address lease time. Exiting


And this entry goes on ever 20 second or so.

If I set a static ipadress on the external side the problem dissapear, but alas so does my clients ability to resolve DNS.  

Has anyone a solution to this problem?

ooops!

Version 6.0.1 contribs

It is a fresh and totally clean install. I have stuck with the "default settings" whenever given the choice.

No contribs installed
No manual changes
No other modifications
The problem was there from the very start

When I assigned the static ip adress on the external NIC , I made a typo when I typed in the gateway....
