Dear list,
While reading the manual I am having difficulty figuring out what the
appropriate hostname.if(5) entries should be for the following
(attempted) network setup:
+ Desired subnet: 172.24.10.0/24
+ HP ProCurve 2900-24G; providing (tagged) VLAN 10 on a physical port
+ bnx0 physical parent interface (no IPv4 address attached)
+ vlan10 logical interface (parent: bnx0)
172.24.10.100 interface address
172.24.10.32 alias address
+ carp10 interface (parent: vlan10)
172.24.10.1 (for failover to another, identical machine)
172.24.10.30 (idem)
The reason I mean to assign addresses to the vlan10 interface is to
easily determine if a machine goes down. I mean to assign addresses to
the carp10 interface for (groups of) services that should have
failover to an identical machine. So far, this is just a test setup,
but I'd prefer to do it right.
What I tried (also see the copied file contents below):
+ on the bnx0 interface, I only mark it 'up'
+ on the vlan10 interface, I configure an interface address and an alias address
netmask on the alias is /32 (as per hostname.if(5); is this correct?)
+ on the carp10 interface, I place two address: 1 interface, 1 alias
netmask on the interface address is /32; as seen recommended by
henning@ in an earlier thread [1]
netmask on the alias address is also /32; continuning on hostname.if(5)
I wonder:
+ Are aliases on carp(4) interfaces supported? (things appear to be working)
+ Are my netmasks and hostname.if(5) files correct?
+ Why am I seeing the following notice in dmesg at startup?
arp_rtrequest: bad gateway value
(occurring 2 times; I'm assuming this fits the number of addresses
on the carp10 interface)
If I should provide more information than listed below, please let me know.
Thanks for any insight,
Rogier
