Good News! Our friends in the CAIDA research group at UCSD have come up
with a new machine for amprgw, quite a bit newer than the existing one,
and with faster CPU, more cores, and more memory. It also has RAIDed
disk and dual power supplies, although unlike the current amprgw, it
won't be on a UPS.
(There isn't a UPS in the new building where the new machine is located.
Luckily our power is pretty reliable; besides buying utility power,
UCSD also generates its own from solar and natural gas sources. And we
don't have lightning storms very often here in the almost-desert.)
There will be some minor differences between the machines, of course,
although small enough that I hope to move all the services over from
the old machine to the new one over the next several weeks.
The primary difference is that the gateway will have a NEW ADDRESS
and a slighly DIFFERENT NAME. Instead of being known as
'AMPRGW.SYSNET.UCSD.EDU' as the current one on address 169.228.66.251
is known, the new machine will be 'AMPRGW.UCSD.EDU' (no 'sysnet' in the
name), and will be on address 169.228.34.84. You should probably adjust
your firewalls soon, letting both machines in for a while, as they will
both be operating at the same time as services are moved from old to
new. Do not move your tunnel endpoints to the new machine quite yet;
that won't work until the routing software is installed and reconfigured
for the new address. I'll let you know what it's ready for that.
