Buddy of mine asked me a question over chat today: “how do I show my machines’ IP at login prompt with out logging in?” He is referring to his Virtual Machine in this case. He does not want to have to log in to the server to see what ip it has (since its on dhcp) for him to ssh in or hit it from the browser. I could have answered him with a simple how to but what is the fun in that? So I decided to give some background on how login prompts are done and show what can be done.

When Linux server boots up, it calls a program called mingetty. This program creates that infamous login prompt as show in a screenshot:

You can see how server calls the mingetty program by looking at /etc/inittab. You will see a block like below:

# Run gettys in standard runlevels
1:2345:respawn:/sbin/mingetty tty1
2:2345:respawn:/sbin/mingetty tty2
3:2345:respawn:/sbin/mingetty tty3

I was just reading Fabrizio Capobanco’s take on the MySQL excitement (”this move is clearly into the right direction”) when it occurred to me that the situation is related to the comments recently made by the former CTO of Kaplan Test, Jon Williams, at the recent OSBC conference.

As I wrote at the time: “Another point Jon made was that the subscription model helps keep open source vendors on their toes as every year he gets to decide whether they will received another payment.”

In other words, as …

I was able to catch up with Mr. Bono Jacon Jono Bacon, Ubuntu community manager, not long after he and his miscreant buddies that call themselves "LugRadio" had hosted their very first "Rock Conference" in the U.S aka LugRadio Live USA 2008

“Sun to Begin Close Sourcing MySQL” screamed the headline on Slashdot last night. The headline is not entirely accurate (although slightly more accurate than the bizarre statement that “Sun has had a very poor history of actually open sourcing anything”).

So what is going on at MySQL? To get to the bottom of that you have to weave together a number of posts and comments from a number of sources. First the article behind the Slashdot headline:

“Just announced: MySQL to launch new features only in MySQL Enterprise,” states Jeremy Cole, which is a much more accurate description of the state of affairs. “MySQL …

Since the recovery from my recent outage, I’ve noticed that none of the normal feed sites where my posts normally show up caught the last post, so this is a test post to see what’s going on, if it was a temporary glitch, or what.

If you didn’t see the post linked above, please read it if you’re happy with your web host. I’m looking for a new one :-/

While reading Colin's post about LugRadio Live, I stumbled over the Zumastor Linux Storage Project. Going through the project home page and their HOWTO got me curious - could this eventually become an alternative to using DRBD (for replicating data) and LVM snapshots (for performing backups)?

Zumastor is Free software that adds enterprise storage features (primarily improved snapshots and remote replication) to Linux.

Snapshots

LVM already lets administrators create snapshots, but its design has the surprising property that every block you change on the original volume consumes one block for each snapshot. The resulting speed and space penalty …

Ok, this blog is currently hosted by 1and1.com, and I think that needs to change, which is sad, because up until recently, I’ve been pretty happy with the performance. However, I recently had an issue, and some things came to light about my package that I wasn’t aware of.

First of all, the maximum time a process can run is about 6 seconds. Second of all, the maximum number of processes you can have running at once is 12. When I asked if this was a limitation of my *package*, the answer I got was that it was a limitation of all shared hosting accounts.

This blog started throwing 500 errors some time yesterday. I called support late last night and some lady said that she was running a tool that should fix my issue, and to call back in 30 minutes if the problem persists. Well, I’m sick as a dog, and it was late, so I went to bed. This morning, the problem was still there. I called support 3 times today, got cut off twice, and …

The solidDB for MySQL database engine for MySQL may have lost its sponsor following IBM’s acquisition of Solid Info Tech but events at this week’s MySQL Conference and Expo prove the certified engines program is alive and well.

Not only has Oracle announced that its Innobase subsidiary has updated InnoDB transactional storage engine, but there is also a new member of the certified engines program.

Kickfire has recently …

The very brave soul, was Aaron Bockover, from the Banshee media player fame (via the LugRadio Live USA 2008 weblog). There were a few interesting highlights from these gong-a-thong sessions…

Zumastor
Dan Kegel spoke about the Zumastor Linux Storage Project. Want snapshots and remote replication in your Linux filesystem? This one does just that. From the contributor list, it looks like its all Google engineers hacking on this… Yes, this is better than LVM. No, I haven’t tried it yet.
