Connect Specification versus Man Page

09/22/2007  IIII
Relevance: 6.82
Ulrich Dreppernoted a difference between the Linuxconnect(2) man page and the POSIX specification. The former states,"connectionless sockets may dissolve the association by connecting to an address with the sa_family member of sockaddr set to AF_UNSPEC." The latter reads,"if address is a null address for the protocol, the socket's peer address shall be reset." Ulrich explained that he preferred the description in the Linux man page, but the Linux kernel seems to actually follow the POSIX specification,"is this functionality which got lost over time? Or is the man page wrong and this never was the case? Is this a worthwhile change?"

Plotting your Web site visitors on a map

05/23/2008  III
Relevance: 6.52
ApacheMap plots the location of each Web hit your site receives on a Google Map. The utility converts IP addresses from Apache logs into longitude and latitude information using hostip.info. HostIP relies on users submitting information about what geographic location should be associated with an IP address. This can present problems, because some IP addresses cannot be resolved into geographic information. In fact, the IP address I was using when I visited hostip.info was not recognized, but sites such as geoiptool.com offered a reasonable guess as to my location based purely on my IP address. Regardless, the results of a geographic lookup from an IP address should always be taken with a grain of salt.

RT mailgate

08/18/2007  IIIII
Relevance: 6.17
I use RT as a request/bug tracker, but until recently hadn't set it up with an email address plugged directly into it. This was because I don't run my own email server - that's centralised - which makes setup a bit more difficult. And undocumented, hence this post. Convincing users to use a different email address may well be tough, but at least you yourself can start bouncing relevant emails to the RT address, thereby creating a more trackable system. There are 2 basic steps: 1. setting up the mail gateway to RT; 2. mail pickup from the external central server. Note that I'm using exim4 - other mail programs will obviously work differently. These are the details...

Who understands the OSS community?

08/20/2006  IIIII
Relevance: 5.89
Jim Morrison once said"You can't petition the Lord with prayer". To paraphrase that it I'd like to say"You can't address the OSS community", because it is much too varied to be addressed. What do you expect when you address the community like it is a company? That there will be a board meeting? That we will issue a press statement? That all of a sudden the community will change its corporate strategy? We have none of those things!

Automatically add contacts to KAddressBook with KBBDB

10/26/2006  II
Relevance: 5.68
Managing your address book and appending new addresses can get tiresome. If your email client is KMail, KBBDB can help with part of the job. This Perl-based filter sits idle waiting for messages to show up, then extracts any new sender's email address into KAddressBook.

Boost Firefox address bar completion

10/23/2007  IIIII
Relevance: 5.62
When you type a URL into Firefox's address bar a drop-down menu appears based on your history. To select the most relevant entry you use the arrow keys (or your mouse) to select it. For better URL auto-completion have a look at Firefox's about:config area and set the browser.urlbar.autoFill value to true.

Setting up IPv6 on Linux

02/10/2008  IIIIIII
Relevance: 5.60
IPv6 is the future of IP, and it’s a good time to start learning about it. It’s very easy to put an IPv6 address on Linux. IPv6 addresses have 126 bits. This allows for an enormous address space.

Key-enabling kernel extensions for AIX version 6.1

11/03/2007  IIIIIIIII
Relevance: 5.59
Diagnose and service memory overlays and address errors more efficiently with POWER6 processors and AIX Version 6.1. In the AIX operating system, software components share the kernel address, creating a serviceability issue for the AIX kernel and kernel extensions.

Step-By-Step Configuration of NAT with iptables

11/22/2006  IIIIIIIIII
Relevance: 5.40
This tutorial shows how to set up network-address-translation (NAT) on a Linux system with iptables rules so that the system can act as a gateway and provide internet access to multiple hosts on a local network using a single public IP address. This is achieved by rewriting the source and/or destination addresses of IP packets as they pass through the NAT system.

Relevance: 5.19
A number of KDE related news stories are floating about the interweb today, so here's a quick round-up. Aaron Seigo writes his KDE e.V. Presidential Address on his blog. Over at Ars Technica, I have an article talking about the future of KHTML and Webkit. Daniel Molkentin has published a new book on coding for Qt 4.x and lastly, I've stumbled across a short visual tutorial for those Mac OS X users among us that are looking to help test the KDE/Mac snapshots.
