Re: [Kea-users] bind kea to non-local IP

I’m happy to try to resolve my problem of sticky clients another way, I just don’t see how. On Thu, Dec 14, 2017 at 9:47 AM Francis Dupont wrote: > Munroe Sollog writes: > > Actually Bind9 supports 'rescanning' for new IPs to listen on and HAProxy > > supports listening to

The only server I have with macOS is a local caching proxy for App Store things. I couldn’t even begin to tell you what it supports in this regard. On December 14, 2017 at 9:31:34 AM, Francis Dupont (fdup...@isc.org) wrote: My concern is simple: it is not in the

Re: [Kea-users] bind kea to non-local IP

My concern is simple: it is not in the standard and it defeats the common code which scans interfaces to get all the addresses a network server may individually bind to. Now to be frank IMHO a feature which allows to bind to any address is basically a bit dangerous... Now if you still think that

Re: [Kea-users] bind kea to non-local IP

Francis - Actually Bind9 supports 'rescanning' for new IPs to listen on and HAProxy supports listening to non-local IPs. The real problem we experience is that there are many poorly implemented dhcp clients. When it come time to renew its IP address, it contacts its last DHCP server and if that

Re: [Kea-users] bind kea to non-local IP

I concur with Munroe. I maintain https://github.com/jsumners/ucarp-rhel7 for my HAProxy failover setup. My guess is that your opposition could stem from multiple OSes not supporting this sort of socket binding. Some quick searching shows me that at least FreeBSD supports it via the “IP_BINDANY”

Re: [Kea-users] bind kea to non-local IP

Kea is like 99.99% of network servers I know: it binds only to local addresses as required by the standard socket API. Regards Francis Dupont PS: I am sure you'll get the same problem with bind9 for instance. ___ Kea-users mailing

[Kea-users] bind kea to non-local IP

VRRP should allow for a quick and easy way to implement a failover pair of dhcp servers without breaking poorly implemented DHCP clients (clients that won't re-broadcast the dhcp request when the renewing server doesn't respond). However in order to implement keepalived, you have to enable
