Generic Listname Identification

As you might suspect, I’m subscribed to a large number of mailing lists (most of which I host myself).

One of the problems with mailing lists is that, if you use a singe email address for all your list subscriptions, there isn’t an easy way to file individual list messages based on the list name.

The other day, however, I found a rather handy procmail recipe that helps with that work…

SecureCRT and OpenSSH

I use Vandyke’s SecureCRT to access my linux machines. Due to the recent increase in the number of attempts to break-in to my systems via SSH, I decided it was high time I switched to using public/private key authentication instead of simply password.

I had devil of time figuring out how to get the public key generated by SecureCRT into OpenSSH’s authorized_keys2 file.

After digging through the SecureCRT help file for a bit I finally found the command (it was pretty obvious, had I read further).

cd .ssh
ssh-keygen -X -f >> authorized_keys2

Now I just have to figure out a way to keep my public keys with me whenever I might have need to access my systems without a system I work on normally.

This was a bad weekend

This weekend was supposed to be a nice quiet, calm, time… I had planned to spend it getting some files organized in the two filing cabinets I purchased from MKS (getting rid of old stuff in anticipation of our move to new digs).

Friday was the company holiday party … it’s always been enjoyable … even if I don’t like dancing (Ginny ends up dragging me onto the dance floor a few times). This time, unfortunately, Ginny’s dinner didn’t agree with her… so we headed home early.

Once home, I made sure Ginny was comfortable … and went downstairs to dink around with the computers.

I then made my fatal error.

I decided to upgrade the main linux system to Fedora Core 3. I figured it would be fairly straight forward to upgrade from Redhat 8 to FC3.

New Server

I got a new server … it’s a Dell PowerEdge 420SC … I’ve named it Gondor.

I originally tried to install Fedora Core 3 on it via NFS mount, booting from a compact flash disk, but it didn’t take. Not sure why.

So I burned the CD’s and installed from there. Worked like a champ.

I think I screwed up the Dell diagnostic partition though … or the master boot record. I’ll have to play around with that.

I’m going to slowly migrate stuff over to the new server … it’s not going to be an easy pick-up and drop-off like it was with the last server migration.

Out of disk space

Had a minor emergency today … my main linux machine completely hung up (for no apparent reason at the time).

My first indication that a problem was a foot was when Ginny asked me if there were any problems with our internet connection.

I didn’t think so, but I checked … I could get to DSLReports without a problem … I was even able to run a speed test (with respectable results).

Ginny told me she wasn’t able to get to her blog. So I went over to the actual machines and checked out TheShire to see if something was wrong. Something was. I wasn’t able to logon as root.

Darl McBride is a Maniac

Not my words … my friend Jim’s.

He pointed me to an article in TechWorld where they obviously omitted a small part of Darl’s statement (the obvious omission is in brackets) …

When people say SCO is just a litigation company, it really bugs me, [and I’ll sue the pants off of anyone who disagrees with me!]
– Darl McBride, CEO of SCO

Of course, the statement that got me was:

McBride also made clear his overriding goal – the destruction of the free software movement: “Wait until the SCO battles are over and let’s see if it’s free or not.” McBride has repeatedly said in the past that free software stifles innovation and harms the IT industry because companies can’t produce great products without any financial return. He continued to rant: “Keep your eye on the [court] filings. Over the coming year, one of the things that you’re going to see is that Big Blue has got big problems.”

Jim comment “that means destruction of the constitutional right of freedom of assembly” … and my only thought was that “People like McBride are against concepts of freedom … they want all the power themselves.”.

I guess McBride (and SCO) is a ‘corporate darwinist’ … he belives in survival of the fittest … ‘course cockroaches have survived for millions of years too.

Video capture card problem — RESOLVED!

Well, the video capture card problem has been resolved.

I ended up going over to Frys yesterday and picked up a motherboard, cpu, and memory (2 motherboards, actually, more about that later).

The upgrade went smoothly … Linux adapted to the new hardware without a problem. Windows XP, however, wouldn’t even boot. I had to reinstall. I kind of expected that.

However, the capture card is seen by the PCI bus now, and is fully functional in XP. I need to figure out how to make it work in Linux though.

Video capture card problems

Well, I got the video capture card finally … plugged it into my system (mordor) and … it didn’t work.

Tried a few different configurations, even booted up into WinXP (mordor usually runs Redhat Linux Fedora, but the card was just never seen.

I brought the card into work and plugged it into my workstation … it was seen and recognized as soon as I logged on.

Well, that obviously means my play machine is broken. Time to upgrade.

I think I’ll swing by Frys today and see about picking up a cheap motherboard & CPU. I think they have them on sale again.
