RE: [CentOS] assigning best gateway via DHCP
What might I do Linux-wise to create a system that looked at multiple gateways and then assigned (via DHCP) the gateway that was the least congested? Anyone have any good suggestions in this department? Your assumption is that the level of congestion would remain unchanged for the length of the lease? Maybe an alternative is something that hands out one gateway then decides possibly what ip to masquerade with. jlc ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Yeah,
I don't know how sexy the solution would be, but you could poll for
throughput/availability
with a script, then rewrite the iptables rule for example taking the new,
preferred outside route as
your new external IP to masq with. It would be functional, and given the
external link your moving
away from is likely down you probably don't have to worry about existing
connections, or do you? :)
Once you rewrite the rule and refresh it, current connections getting masq'ed
will be killed. If your
in the middle of secure connection to something/someone or a download, it will
be terminated.
There is *no* way of maintaining any connection between different paths in this
situation unless you
specifically have something setup with your provider that is aggregated across
{n} connections, but then
we wouldn't be discussing this:)

[CentOS] assigning best gateway via DHCP
What might I do Linux-wise to create a system that looked at multiple gateways and then assigned (via DHCP) the gateway that was the least congested? Anyone have any good suggestions in this department? (I am planning on having a temporary wireless mesh with several satellite uplinks, and I would like to forward requests to whichever uplink is the least utilized) ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
