Dear all, On a new server (postfix dovecot postfixadmin Centos) I did define quota=0 in postfixadmin However suddenly a user with more than 9Gb of mail got his mailbox new/cur empty and maillog shows: Sep 3 15:43:56 mail16 dovecot: lda(brouwerb at scholarium.nl): Error: sieve: msgid=<alpine.LRH.2.20.1509031543050.16381 at streaming2.antenna.nl>: failed to store into mailbox

Some years ago, Congress passed legislation which affirms the right of individuals to install over-the-air television antennas, satellite-TV antennas, and "fixed wireless" antennas, in areas of their property which (1) they own, or (2) they lease or rent, and which are part of their "exclusive use" areas. The "exclusive use" phrasing covers areas like private patios, private walkways, balconi...

They're a ton of fun to tinker with too. I am also an old guy and didn't want to use the Rpi for this purpose. However, many years

...ct. (ok so I'm media-whoring) Any ideas as to how I can offer both Vorbis and mp3 streams with minimal reconfiguration of my existing setup will be greatly appreciated. The setup: At 10 night clubs: 10 old Mac G3s running Gentoo Linux, OpenSSH and Ices2 (from CVS). 10 Wifi access points / antennas. At the 'net end of things: 1 access point / antenna connected to an Apple Xserve running Gentoo Linux and Icecast2 (from CVS), as well as Apache, PHP, and OpenSSL.

I'm trying to install a program from a CD-ROM that is included with a publication called the ARRL Antenna Book, 19th Edition which claims compatibility with Windows up to 2000. Running the setup program I get the following (I am executing it from the CD-ROM): $ wine ABSETUP.EXE Disabling HW TCL support Disabling HW TCL support Disabling HW TCL support Disabling HW TCL support wine: Unhandled

...anywhere on the surface of the world is -15.55dBm, or 0.03mW and the minimum power available within 5,000km is about -3.55dBm, or about 0.44mW. Half a milliwatt is quite a bit to work with, excepting the noise effects of 1/f ("pink") noise and local interference. Higher-gain receive antennas are easy at 60kHz (iron-core loopstick or a multi-turn loop). According to NIST's site, however, WWVB is currently running at half-power (35KW ERP; 75.45dBm) so cut the available power in half at the moment. However, WWVB's signal _is_ 60kHz, and so any building of metal construction,...

Warren, one slight correction on an other wise nicely written bit of info: The time transmitted from WWV is not Mountain Time. Even though the WWV transmitter farm is located in the Mountain time zone, the signals are transmitted as "Coordinated Universal time", UTC, or 'Zulu' time. Here, you can listen to a recording made at the transmitter site for the 5Mhz signal:

A few years ago, one of our interns was curious about system time keeping features in computer systems.? This intern was also the proud owner of an inexpensive Radio-Controlled Clock. The intern wondered why computer motherboards were not just equipped with a chip like the ones in the RCC so that their system time would always be correct. I posted a question about this on the CentOS email list

Ha! You're the exception to every rule! That's a sweet setup though! Way cheaper sacrificing a Pi to the god Zeus. LOL. Do go look at XCP-NG, if you're not familiar. Really nice.

NetworkManger should work pretty nice and good as required. Just run the right cronjob every minute to make sure the connection is up or down and find out if it's possible to reconnect. NetworkManager is kind of does all you need automatically so you should not do anything unless there is a technical issue.

There are two major types: 1. WWVB and its equivalents in other countries: https://en.wikipedia.org/wiki/WWVB 2. GPS clocks. WWVB has several problems: a. It?s

One of our STEM interns recently observed that there are inexpensive clocks that sync via radio to standard time services.? This begged a question about why every computer would not have a radio module to receive time.? Our senior staff did not have a good answer or if time from such a radio module would be supported by the operating system. When I was a student, such questions would have earned

Everybody, In my case I used a RPi as an additional DC for a month or so while making some Samba4 AD improvements to the main DC's. My main DC's run on some nanopc Intel J1800 (cpu) based fanless (about 5" x 5" x 2") box's that by spec sheet draws a maximum of 15W to run on full load. As a DC they never run on full load. These boxes are actually designed to be run 24/7
