Your first stop is here I think, for at least one of your links, and I
have a fair bit of bandwidth here.

I wonder how many telcos will still give you a plain leased line over POTS...

I wonder if there'd be any interest in cobbling up a little microcontroller circuit that could convert synchronous serial to Ethernet. We could use these to emulate leased lines on equipment that doesn't even have Ethernet boards.
I'd be very interested, unfortunately I lack the necessary knowledge. :(
Although, I also say we need HECnet radio balloons and similar, so my ideas are a bit absurd. ;)

Oooooh. Not bad at all. Not too much jitter and doesn't seem lossy.
This is at the same time as I'm saturating the 10Mbps part of the network with a local FTP of a 22Gb file that I need to move over to my Alpha machine.
22GB at 10Mbps? That could take you a while. ;)
Great stress test though.
Also, HECnet needs some leased lines between locations for maximum authenticity. Along with period-accurate modems. ;)

I am very happy.

It was the low-pass filters, not the surge suppression components,
FYI. Those must be fairly decent power strips.

More than likely. Could also be future-proofing or saying you could have 2 saturated 100mbit connections at the same time.
Never mind, because the garage-end of my network is only 10Mbps (most of it is 10Base2 coax).

Seems the tech has improved since I last used it something like 7 years ago. ;)
$59 is a small price to pay compared to drilling holes through exterior house walls and crimping RJ45 connectors.
Unless you happen to be a contractor who doubles as a network engineer. ;)

No, but from what I've recently learned, MoCa is going to be a great solution and I think it's what i'm going to go with.
I ran a wifi bridge many years ago when I lived in Philly. Never worked well and then the school across the street put in a bajillion million watt APs that used EVERY FUCKING AVAILABLE CHANNEL and my bridge just stopped working completely at that point.
That's when I was introduced to MoCA. 100mbit and solid. Also, latency is much lower than wireless.
Also, very cheap (looking now, NIM100s are $15/each on ebay but I paid $5/each for mine) and at least here in the US coax is almost guaranteed to be in place in pretty much every house so you rarely even have to do any major wire pulls.
I should probably have asked my friend who works for a local cableco instead as I lost the bid on the one. ;)
At least I got a lot of 2 I'm not patient when it comes to networking.

IM's are slightly different, as I'm sure you're aware.
The benefits to phone are:
- You are notified when your buddies log on, anywhere on HECnet
- You can control who can message you (i.e. buddies only)

Hello!
It did? Just how far along was this?
Dave that was the fault of the monstrosity keeping your PDP-11 family
company. Including the furry something else that keeps sending....
Well you get the idea.
Half a year or maybe a year ago. Sampsa was running a program which used PHONE to check who was logged in on various machines. When he tried all machines in area 1, MIM got loads of entries in the log for Sampsa's machine trying to talk with machines that were down.
(I might be remembering things wrong, and I might be mixing things up, but it was not as if MIM crashed or anything because of Sampsa's code, but I asked him to stop, as he was filling up plenty of logs as far as I can remember.)

Slight update to the data format documentation detailing the fields within the inner dictionaries of known_circ and adj_nodes.
I really do need to get this stuff online somewhere.
