Hi Jeffrey!
Sorry - I didn't include more information, because the same
configuration was working before
switching to Cent OS 5.2 so I do not expect that it is wrong - I thought
somebody can give me
a hint like "check the ulimits for this or for that ..." - Sorry my
fault here are the informations:
*System: *
Cent OS 5.2, ISC Dhcpd 3.0.5 with paranoia and ldap patch. Started with:
/usr/sbin/dhcpd -f /etc/dhcpd.conf -chroot /var/lib/dhcp/ -lf
/db/dhcpd.leases -user dhcpd -group nobody bond0
*Configuration:*
[root at xdaten ~]# cat /etc/dhcpd.conf
ddns-update-style none;
authoritative;
ignore declines;
ldap-server "xdaten";
ldap-dhcp-server-cn "xdaten";
ldap-port 389;
ldap-username "uid=Admin,ou=Users,dc=base,dc=at";
ldap-password "XXXXXXX";
ldap-base-dn "ou=DHCP,dc=base,dc=at";
ldap-method dynamic;
ldap-debug-file "/var/log/dhcp-ldap.log";
failover peer "dhcp-failover" {
# secondary;
primary;
address 10.0.0.2;
port 648;
peer address 10.0.0.1;
peer port 647;
max-response-delay 30;
max-unacked-updates 10;
load balance max seconds 3;
mclt 1800;
split 128;
}
Logs (from the last test):
The Dhcpd serves all clients until the count of the leases reaches 80
(counted with: grep "hardware" dhcpd.leases | cut -d" " -f5 | sort -u|
wc -l)
(Dec 3 08:04:48) then you get only DHCPACK for Dhcp Refreshes or
when you leases
