This excessive logging behavior started for about 4 days ago.
At least, thats when I got aware of it.
Everything is working just fine, except for this.
My IP-address hardly ever change. I've had the same one for nearly a year now.
There got to be a way to tell it to only log errors, not every connection,
but I don't know how.
I was looking for a way in the syslog.conf, but I have very little
understanding for that tool. ( not a clue ).
Any more hints or clues would be preciated.
This is a snip from my lease file :
lease {
interface "xl0";
fixed-address 217.209.211.129;
option subnet-mask 255.255.255.0;
option time-offset 3600;
option routers 217.209.211.1;
option dhcp-lease-time 1200;
option dhcp-message-type 5;
option domain-name-servers 127.0.0.1,10.0.0.1,10.0.0.2;
option dhcp-server-identifier 10.0.113.1;
option broadcast-address 217.209.211.255;
renew 5 2003/6/20 12:18:03;
rebind 5 2003/6/20 12:26:08;
expire 5 2003/6/20 12:28:38;
}
