Not that I have time to mess with this, but what's the current state of
the art regarding multiple upstream internet connections and possible
bandwidth sharing?
At the moment, I have a work-related SDSL connection (sadly, it's only
384K, rather than the 1.1 MBit I used to have...I moved farther away
from the CO :< ), as well as the personal cable-modem link (dynamic IP
from cox.net) I had at home prior to moving my office.
I'm eventually going to get rid of the cable-modem connection to save
money, but before I do, it's the first time I've had a real-world
environment for testing multiple uplink configurations. Anyone got any
ideas they'd like to see tested? I can't devote a lot of time to this
(I still haven't even managed to get an updated Dachstein-CD out with
the new ssh packages), but I can probably spend a couple evenings trying
out a few things.
Also...I recently got a nifty trick from the local linux users group
regarding time-servers:

There are a bunch listed at www.ntp.org, a.k.a. www.eecis.udel.edu/~ntp.
A possibly better alternative is to use your provider - most ISPs enable
NTP on their routers. This is convenient for them, since they can
correlate router log messages accurately. It's convenient for you,
since
you have a low-latency time source just a few milliseconds away.
Tru running "ntpdate -q" against a traceroute output, e.g.
traceroute -n www.cnn.com | head -5 | awk '{print $2}' | \
xargs -n 1 ntpdate -q
You'll usually find an NTP server close by.

Has anyone tried anything similar with BGP (or similar routing
protocols)? It seems reasonable to expect a router that's not too many
hops away (ie the ISP, or the ISP's upstream provider) would be running
BGP, and while it's hopefully not possible to alter the route list, it
might be possible to import route information. If you could do this on
both links, and run BGP on the LEAF box, you could do *REAL*
load-balancing (or am I missing something major here? I don't do much
backbone type setup/config, so I could be completely off-base).
