What happens when the host uses a dynamically assigned IP address?

However, my ISP seems to change my IP less than once a year, so it's not really a big problem. So I think it more depends on how often do you see address changes? Even then I don't know how much of an issue it is. Cory's IP address changes ALL THE TIME. :) -brian

GORVAX used to run MULTINET as well but I rebuilt it lately as a plain area router. Another idea (not necessarily a good one, performance-wise) is to ask for a VPN connection to somebody on HECnet, make sure you get the same IP address every time you connect the VPN and route the bridge's UDP packets over that. That's how HILANT:: et all are connected, the machine that runs the bridge is VPN'd into my other network, giving it a static (NAT) IP address. sampsa

It doesn't have a TCP/IP stack. ;) sampsa -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

Mark. This is why I manually verify any new user applications and audit what they do for a while. I don't get many hacking attempts or anything on the boxes that I've got telnet open on, it's a different matter once they have an account of course. I could maybe move the HILANT cluster into its own VLAN, so IP access from there wouldn't be a big deal, could even firewall most outgoing traffic. sampsa

Hi Sampsa, I was considering updating the HECNET-INFO in INFO.TXT with an ACCESS field. At present it contains: REGISTER,NOGUEST,NOIP The latter means it is not connected to the internet. With the OS and hardware information, this may be useful for people to see how they can get access to an interesting machine. I hadn't played with FAL for many months, so I discovered the password settings for the DECNET accounts and objects were inconsistent, probably resulting in the security alarms I had mailed you about some time ago (sorry)!

Does anybody mind 'outsiders' getting access to HECnet? I don't mind. Most will probably not explore the fact that there is a big DECnet behind the machines. It is not that we are preventing people today either. It's just that there have never been much fuss about HECnet. However, I can understand if some people feel worried about traffic and issues. If so, let us know, and we'll try to think of what to do. This is why I manually vet the account requests - if the email address or name seem totally bullshit, I just ignore the request. I get maybe 2-3 new users per week on each system..I personally don't want to let the Deathrow guys behind my firewall :) sampsa Sampsa I'd seriously consider picking Steven Hoffman's brains on this before opening a system up to the world.
