| Phoenix -> Telocity curiosities Curious things I have discovered while slowing making the switch from Phoenix to telocity. Can anyone explain?
1. 3Com modem worked just fine but the IP address it returned with DHCP is different from the one I got when I installed the Telocity gateway and it retrieved my static IP address via DHCP. Hypothesis: they left open some DHCP addresses for testing, emergencies, etc. other ideas?
2. I have now converted my TCP/IP settings to use the static IP address returned to the telocity gateway. But I can still send email out through mail.phoenixdsl.com. Surely they don't have open mail relay on their servers? If not, it must mean my new IP address is recognized in both the old phoenix domain and the in the current telocity domain. how can that be?
inquring minds want to know.
thanks for any enlightenment |

| I don't have any answers to your posers, but I do have a question of my own along those same lines. When I had my Copper Rocket on the line I too got a different IP address than the one DHCP assigned the Telocity gateway. If they are handing out IP addresses to machines through the old modems like that, do you think it might be possible to connect the gateway to a hub (Or a switch) and then allow two or more computers set up for DHCP to get seperate IPs over the same line? Not that I want to cheat Telocity out of their extra $10 mind you... Just curiosity. |

Don't think that would work. I have a hub and it was that that I set up request an IP via DHCP. It then distributes local IP addresses via DHCP to the local devices. Those devices don't make a request on the net, only to the hub. So, I had and still have several computers requesting addresses via DHCP going out through the telocity gateway (which they wouldn't use that word) and the gateway only gets one IP address. Actually, I think, the gateway then assigns an IP address to the LAN. I'm not a guru, but I don't think I could get a hub to get two IP addresses. |

It just might work if you were using a dumb bridge like the copper rocket which doesn't have an IP address itself. However, with the Telocity gateweight any DHCP request from the LAN side will be serviced by the monolith itself. Even with the rocket it is possible that they have security features enabled that prevent more than one IP address from working at any given time on a specific port, so you might be able to switch back and forth between computers at will by releasing the IP, but not be able to use both at the same time.
If you try it with the rocket, let us know what happens. |

I dumped Phoenix in Dec 00 and went to OOL. I can still send and receive mail via Phoenix. Maybe someone forgot to flip all the switches off!

Phoenix never had any security... just for kicks, I tried all the other IP addresses on my subnet (after pinging to make sure no one was there) -- yep, they all worked fine, no nasty note from Phoenix. I was too honest (or chicken ) to actually use more than one other than that, though. |

You should be able to use their SMTP server as long as you authenticate. Try turning off authentication (so called SMTP authentication) and see if it still works. POP servers don't normally restrict based on owned IPs since people want to access them from anywhere. |

I couldn't even reach the webserver of someone on my sub because it was, properly, blocked at the CO. I used to have to telnet to another host and use lynx to reach the server. Guess it depends on who maintains the setup. Rhythms/Cisco here (was). |

I think the answers to my curiosities are now in.
1. The telocity gateway has to connect to telocity's database to look up the correct static ip address assigned. To be able to establish a connection to enable your config info (usually, your phone number) to be sent to the database, it has to respond to generic dhcp reqeusts and has a range of addresses it can use for that purpose. once it figures out who you are during the config process, it then gives a dhcp lease for the correct IP address and downloads that to the telocity gateway. So, our 3Coms were able to work because telocity's dhcp server couldn't tell from whence the dhcp request was coming. The telocity server thought the requests were coming from a telocity gateway wanting to connect to the database. So, no reason the 3Coms wouldn't work for a long time. But I seem to get fewer throughput problems when using the static IP now assigned than the dhcp ip my 3Com was returning.
2. the university sites i deal with won't accept smtp send requests from IPs outside their domains. i think that helps reduce junk mail a lot. i just assumed that phoenix would do the same, but evidently they didn't worry a lot about security as other posters have noted.
thanks for your help on the curiosities! |

Well, the wierd thing is, if you run WINIPCFG when your machine is set up to use DHCP via the monolith, you get your Telocity assigned IP as the IP assigned to your NIC. I'm not sure what that means if you have two computers hooked up to the grey monster via a hub, but it sure is interesting. |

The point that I was attempting to make is Phoenix DC'd my SDSL but left my mail account open. Usually when the ISP pulls the plug on you, all your accounts are history. That's all.

Buffalo, NY | My cable email account is working fine though it was over a year ago I left them. My web pages are still up too. One wll-known national ISP left my web pages up for several years after I left.
Phoenix most likely isn't putting any man-hours into stuff like that since it is shutting down. Last thing I'd be concerned with in the circumstances is pulling email accounts. They will all be gone by 15 April. |

| I'm curious... why the 15 April date? |

Buffalo, NY | Someone from Rhythms mentioned that is the date until which they are contracted to provide service. |
