DNS settings

by Deepan

Hi All, I would like to configure my laptop to use 4.2.2.2/4.2.2.3 as DNS. The problems is everytime my machines requests for a dynamic IP via DHCP, my DNS settings get reset. Is it possible to override this? I am running Fedora 8. Regards Deepan Sudoku Solver: http://www.sudoku-solver.net/

Re: [Wlug] SPF

by Keith Wright

> From: Jamie Guinan <guinan(a)bluebutton.com> > > Are any of you admins out there running SPF, or something similar? This question is too hard for me. What is "running SPF"? I have these top secret records in my DNS zone file. keithdiane.us. IN MX 10 dsl.keithdiane.us. keithdiane.us. IN TXT "v=spf1 mx include:speakeasy.net ~all" (Don't tell anybody.) And I send all my mail through speakeasy, by which I mean that the SMTP server at keithdiane.us forwards through there as a "smart host". I don't use Speakeasy web mail, but if I don't forward through Speakeasy, too much mail gets rejected out of hand, just because it comes from a dsl line. (I think. (It's been a while since I tried it, and you never know exactly why you have been rejected.)) On the other hand, when a host sends mail _to_ my server, it does not check its DNS for SPF at all. > How well does it work for you? Compared to what? I'm not sure how it works, because I've really never done it any other way. I do know that spam is way out of hand. I get over 100 a day of total stupid stink'n spam. (This does not count mailing lists that I am subscribed to that I do not actualy read; just really stupid crap in Russian, repetitious attempts to sell stuff I had better not mention for fear of falling into the WPI filter, usw) It's almost to the point where I might do something . . . soon. Real . Soon . . . Now . . -- Keith .

Re: [Wlug] SPF

by Dick Goodman

I run 4 Linux mailservers and do all my own DNS for multiple domains Yesterday (I think) one account on one domain got about 500 emails similar to what you described in a period of about 30 minutes. I have SPF records on many of my domains (because it was so simple to set up), and promptly added it to the DNS of the domain of the affected account. Today the number of such emails was down at least 10x, but I can't say for sure it was the SPF that did it.

DKIM is the "new SPF" standardized effort backed by Yahoo!, Cisco, Sendmail, Inc. and others. It combines Yahoo!'s DomainKeys and another one whose name I forget now. If I were to set something up, I'd probably use DKIM, but I have no experience with it myself.

SPF

by Jamie Guinan

Hi, Are any of you admins out there running SPF, or something similar? http://www.openspf.org/ How well does it work for you? Today I started getting a large number of "undeliverable" responses due to spammers forging my email address in the From: address. Wondering if SPF is worth the trouble to set up. I'm using postfix, btw. Thanks, -Jamie

I've got a flash card reader that, if it's got a card in it when the computer is turned on, will forever fail to recognise that it's got media. However, if I insert the media after Linux has recognised and reset the device, all is good. Perhaps you had a situation like that? I blame BIOS weirdness, really. -- Aaron Haviland 34 Wayne Ave, Dudley, MA

Is the external USB drive self-powered? Did you power-cycle it at any point? The device itself might have gotten wedged. It might have shown up as /dev/sda* on some of those interim reboots, depending on whether there were any other usb storage devices present. "lsusb", and the tail command Eric suggested, are your friends. What is sda currently? [ these work on 2.6.23, not sure about earlier kernels ] $ cat /sys/block/sda/device/model $ cat /sys/block/sdb/device/model Anyway, glad to hear it at least works again. -Jamie

I booted up another kernel a 2.6.18, and I noticed that the /dev/sdb* files were still missing! All of the other /dev files were there.

Is this device at the end of a USB hub??? I ask because I run into this issue when I plug my PSP into a usb hub connexted to my FC8 box. If I plug directly in I don't see this issue...

Missing /dev files

by Chuck Noyes

Hello, I had mounted an external usb drive /dev/sdb2 onto /media/sdb2 and was coping several mega-bytes of files to it when I got some I/O errors. Then I noticed that all of my /dev/sdb* files were missing from /dev. When I do an ls -al /dev, all the files are there except the sdb files. How can I get these back? I'm running Ubuntu 'gutsy' 2.6.20-16-generic. Thanks, -- -Chuck
