I have a hard drive that is powered via usb and I know you need to plug both of the USB cables from the Y into the same usb 'block' (you can't plug one in the front and the other in the back). If you were doing that, try plugging them in next to each other. Otherwise I think it's a usb problem. That's easily detectable by using a jump drive in the same ports and check /var/log/messages or dmesg. Also, if it is bad usb hw on your myth box the hub won't fix it (which is more reason to try one). My usb hd has a slot for power, does yours? If so I'd suggest trying it.

REMINDER: Upcoming meeting Wed evening 7PM

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, We have a WLUG meeting coming up on Wednesday, April 16th, at 7:00 PM. Directions to the meeting can be found on the WLUG website. There is a remote possibility that I will miss the meeting, which is why the meeting topic is listed as TBD on the website. If I cannot make it, I would recommend conducting the meeting as a Birds of a Feather session. However, if I am able to make it (95% probability), I'll bring my laptop, battery, DC-DC converter. We can have a discussion about reducing power consumption in laptops. I can do a quick demo of the PowerTOP application (see: http://www.lesswatts.org) I don't think this will take up the entire meeting, but we can use it as a starting point for further discussions. I also have the CPU frequency control applications installed to control the clock frequency. Naturally, we'll go out for food and refreshments afterwards. See ya later!

Yes. As I said, that was all done years ago. Though actually I never called them. It was done via email. You might think that answering email would be the basic entry level requirement, the sine qua non/nada/zilch, that any moron would learn to do before becoming an ISP. Sadly, most Idiot Service Providers seem to be totally unable to answer email from customers. They are only interested in phone calls from people who have no email. Speakeasy has someone who knows what is and who answers email at 2am Sunday faster than most of them can get an sales droid to pick up the phone during business hours. Anyway, I run a primary name server while they run a couple of secondaries and reverse DNS. I think I may have an officially "dynamic" IP address, but it was set up before DHCP. Speakeasy gave me an address when I signed up and since then neither of us have had any reason to touch it. -- Keith

Except that, as Keith has experienced, and as I have also experienced, some systems recognize the sending IP address as coming from a block of known dynamically assigned addresses and reject the messages/connections even though all the domain info has been set up correctly. I have used TZO's services to work around this in the past. Highly recommended.

Yes, that's a good idea. That's why I did it about four years ago. It works well, maybe sending mail through Speakeasy is not really necessary, but I seem to remember that I had a problem with rejected mail when I sent it from my own machine. Maybe something else was wrong, but it's not too broken now, so I don't fix it. -- Keith PS: The answer to the original question was that I use SPF for outgoing mail, but not incoming. It works, but maybe anything else would work as well. Maybe something else would work better. Outgoing SPF requires setting up a Domain Name Server. Once that works it's easy. Example zone records were in the original answer. Incoming SPF reqires setting up an SMTP server. Even after the SMTP server is working, setting up SPF is fairly complicated. Maybe there is a distribution that does most of the setup for you.

When you get a domain name, and set up your MX, reverse DNS, and other records properly, other mail servers recognize your mail server as being part of a legitimate domain instead of just an anonymous user of an ISP's IP address pool. -- Rich
