Nope. I noticed that Psilo was down, but only now did I recheck and as psilo was back up, I restarted the bridge.
I've restarted mine several times and I'm still not getting anything outside my LAN. :\
Hum. So psilo rebooted again a few hours ago... Restarted the bridge right now.

Looks like you're missing libpcap and bpf (?):
That's entirely possible. Or they could just be somewhere weird.

PS: How is this network connected to the rest of HECnet?
Currently it isn't. It was supposed to have simh running a copy of vms but that never got setup due to not being able to get the networking to function properly (tun/tap wasn't doing what it should).
I need to upgrade that machine so that I can use the crossbow network virtualization but upgrading a machine that i have limited access to is less than a fun idea. :)
Once we get the bridge working on wiggum I can also connect it to someone else. Last night while I was falling asleep I thought about this. I could also connect the bridge to my house, but that would be silly. If I'm going to do that I could just go ahead and setup the vpn tunnel to go to my house and skip wiggum altogether. :)
I'm setting up a new VM at home who's sole purpose in life is to be a vpn concentrator and HECnet bridge. I'll get you new vpn info sometime later this morning.
At that point you'll be bridged to my local DECnet network. I don't have any machines running locally (I really need to do something about that) but I'm connected to Dave M. and Peter L. via GRE tunnels on our cisco boxes.

I connect to your VPN server.
Let's say I get IP 10.0.01, your bridge is on 10.0.0.2.
I then just point my bridge at 10.0.0.2:4711, you point yours at the 10.0.0.1:4711.
UDP goes over VPN?

Yeah, that's an option, but here is what I was thinking.
You connect via openvpn to me. I redirect a port on my IP to go to yours.
For example, my server is 208.85.173.157. My end of the vpn tunnel is 10.42.3.1 and your end of the vpn tunnel is 10.42.3.2.
I had a nat rule that takes tcp port 9022 from 208.85.173.157 and redirects it to 10.42.3.2 port 22.
What this would allow you to do is ssh to 208.85.173.157:9022 and get directly connected to whatever is running openvpn on your end.
In theory.
In reality, it's not working for some reason. :(
It really should, but I haven't touched ipf/ipnat on this box in so long I might have something setup incorrectly (i used to do exactly this).

Dude, there is no server. Let me explain :)
My ISP offers non-public IPs, so that's NAT one one - no way to forward a port.
Then I got a router, doing the local NATing, NAT two. Sure i could forward a port, but it ain't gonna help as the packets will never get to me from the ISP.
So I figure I connect out to you via OpenVPN, get a static IP x.x.x.x and then point my bridge at your static IP y.y.y.y (both of these are on the VPN), and you do vice versa.
Sound reasonable?

As Paul mention, pthreads would probably be a good start if you want to do something more intelligent. You need to start thinking asynchronously.
My desire for this is basically because my ISP is NAT'd to hell - I have no way of getting UDP packets back to my network, as the ISP gives me a non-routable address.
Why go with this ISP? Well it's about 3x faster than the DSL I can get in the sticks over a 3G signal, with unlimited bandwidth and usage.
But sucks for HECnet..

Nope. I noticed that Psilo was down, but only now did I recheck and as psilo was back up, I restarted the bridge.

We're good to go. I just need a copy of the bridge program when you get the chance.
