[HECnet] Alternatives to bridge when running via a dynamic IP address

Actually, who cares.   All of this happens at this end.   I can tell this
end to do the lookup every second if I wish.   In reality it is usually
done in some number of minutes.   As for the reboot, that's why it is a
dedicated machine.   It can reboot as often as it needs to - I don't
depend on it except to provide connectivity to this site from remote
sites that have dynamic IP addresses.   The actual reboot is only a few
minutes.   This entire process is automated and it is able to inform via
email (delayed using NMAIL) anyone necessary that their was a change in
state (address).

The question is how long does it take to detect, and is a reboot every
time acceptable?

This issue has been dealt with here.   The declab.net site runs a 
dedicated VAX with Multinet that polls the other end at predetermined 
intervals.   When the other ends' address changes this end makes change

to the Multinet database and reboots.   This software has been in use 
for well over a year and appears to work very well.

It does require the use of DynDNS at the end that changes addresses so

that this end can do the lookup.

Won't the IP address remain unchanged as long as you keep the router
up and running?
Or would thet be too costly?

Guys,

Might as well explore this as an option.

The 3G network enabled Vigor 2800 router that I will be using at the 
DEC Legacy event appears to be working reasonably well, but 
unsurprisingly there does appear to be some fluctuation in the IP
address.

This means that an alternative to Johnny's bridge program might be 
called for. I have a dynamic DNS reference set up and now updating 
periodically, hecnet.no-ip.org, the question is what can I use as an 
alternative to the bridge program which will cope with IP address 
changes?

I seem to remember Multinet tunnels being mentioned in the past, do 
they support dnydns, or any other technology?

Thanks for the help,

Mark.
Unfortunately not. I've seen three IP address changes in about the 
same number of hours.

I don't know whether this poor performance is down to the completely 
haphazard location of the dongle, or whether it's always this rubbish 
but you don't realise when all you're doing is browsing the internet.
My experience of using a 3G dongle for anything other than web 
browsing is very limited!

Regards

Mark.
