Hello
I've setup dhcp 3.1.0 with ldap patch under debian lenny.
twice daemons on primary and secondary are launched and communications
with ldap is fine.
This server act as main DHCP daemon for various vlan segment with dhcp
relay.
The problem is that "Failover" doesn't works" ...
On the primary
May 3 18:28:16 dhcp1 dhcpd: failover peer failover1: I move from
recover to startup
May 3 18:28:31 dhcp1 dhcpd: failover peer failover1: I move from
startup to recover
May 3 18:28:31 dhcp1 dhcpd: failover: link startup timeout
On the secondary
May 3 19:05:14 dhcp2 dhcpd: failover peer failover1: I move from
recover to startup
May 3 19:05:29 dhcp2 dhcpd: failover peer failover1: I move from
startup to recover
Using tcpdump I can't see communications between primary and secondary.
Setup on primary
failover peer "failover1" { primary; address 192.168.0.2 ; port 519;
peer address 192.168.03; peer port 519; max-response-delay 60;
max-unacked-updates 10; load balance max seconds 3; split 128; mclt 3600; }
Setup on secondary
failover peer "failover1" { secondary; address 192.168.0.3; port 519;
peer address 192.168.0.2; peer port 519; max-response-delay 60;
max-unacked-updates 10; load balance max seconds 3; }
Subnet are setup as this :
subnet 192.168.0.0 netmask 255.255.255.0 {
option broadcast-address 192.168.0.255;
option routers 192.168.0.1;
option domain-name-servers 84.232.1.100,194.179.1.100;
pool {
range 192.168.0.234 192.168.0.244;
deny dynamic bootp clients;
max-lease-time 86400;
default-lease-time 86400;
failover peer "failover1";
}
}
subnet 192.168.2.0 netmask 255.255.255.0 {
option broadcast-address 192.168.2.255;
option routers 192.168.2.1;
option domain-name-servers 194.179.1.100;
pool {
range 192.168.2.100 192.168.2.254;
deny dynamic bootp clients;
max-lease-time 86400;
default-lease-time 86400;
failover peer "failover1";
}
}
subnet 192.168.1.0 netmask 255.255.255.0 {
option broadcast-address 192.168.1.255;
option routers 192.168.1.1;
option domain-name-servers 194.179.1.100;
pool {
range 192.168.2.100 192.168.2.254;
deny dynamic bootp clients;
max-lease-time 86400;
default-lease-time 86400;
failover peer "failover1";
}
}
Not that I've disable the iptables (all policies set to ACCEPT)
Any tips, ideas are welcome
Thanks
