I’m going to do a few articles on building RPM’s as much for my own reference as anyone elses. I’m not an expert on the subject by any means… I do this from time to time, rebuild an rpm for an older system (or even a newer system that doesn’t have an official rpm for.) I have a tendency to forget things that I don’t do frequently. The first part of being able to rebuild rpm’s is to have what’s called a build environment. For starters, I’m using Mandriva 2006 (older versions I used Mandrake 10.1 or 10.0, etc.) In your home directory you need a folder called rpm.

Kontact/ korganizer “unable to save event”
OK – so as I have mentioned after upgrading to Mandriva 2006 I was looking at the possibility of moving from Evolution to Kontact as the main mail client. I moved contacts and got things massaged quite well. One of the neat features in Kontact is the ability to have multiple address-books/resource names. Anyway, I moved on to calendar items which given that some of what I do is recurring appointments is fairly easy to reconstruct if necessary. Anyway, I got those copied over and thought I’d take advantage of being able to use different calendar files to organize different things. For instance I thought – why don’t I do a seperate file for Holidays…

Securing SSH
I REALLY like secure shell (SSH) for remote access to linux machines. You can do more than just a “telnet” like remote shell with it. (Port forwarding.) However, the default configuraton for the openssh-server is sometimes a bit less tight than I would like. For that reason on a new install, I usually like to make a few changes. I don’t know if I’ve mentioned this before, but I haven’t devoted a post JUST to this, so… here we go.

A Tip for cleaning up an infected PC
There’s a joke that many people bring out when new Windows viruses hit big…. it goes along the lines of, “download a fix here” and the link points to a knoppix linux livecd download, or a Mandriva download disk, fedora/etc… Some say linux isn’t affected by as many viruses because it lacks market share, I would point out that server market share (take a look at how many linux web servers there are…) would seem to tip the scales a bit, but that’s not the point of this post. What is the point is this…. When you have a Windows pc that is infested what you should do is disconnect from the internet. The problem is, that typically prevents you from getting the tools you need to fix the machine.

Migrating Contacts from Evolution to Kontact
I’ve toyed around with the idea of migrating everything over to Kontact for my mail. I’ve used Evolution since moving over to linux, but there are some things about Kontact that just seem slicker to me. While I was doing the install, I had the laptop setup to receive messages through IMAP and used Kontact as the client. There were a few features that I wanted to spend a bit more time with. So, the first thing is getting the data into Kontact.

Disinfecting a PC… part 11
All in all, what I’ve documented was a bit over three hours worth of attention to the machine (much more for the full scans, but I didn’t have to stand and watch them.) I didn’t document a sidetrip to a second antivirus scanner. It’s nice to see a system cleaned up that had been so thoroughly infected. There are a couple other notes I should pass along though. When a system has been trojaned the BEST advice is to wipe the disc and reinstall from scratch. (Erase/reformate/install from scratch.)

Linux php-exploit bot
Incidents.org writes to remind as that bot’s aren’t just for Windows. The recent PHP exploits have seen the use of the “kaiten” bot. After infection on the system it connects to an IRC server. It would primarily target linux systems. They do give a very good way to blunt most Linux bot-style malwares…

The 2nd journey begins… Mandriva 2006 upgrade 2 – Part 10
I think it’s time to wrap things up. The KDE start new session option is back after the changes I mentioned to the /etc/kde/kdm/kdmrc file I mentioned in a previous post. There are no outstanding issues from the upgrade. (I need to adjust the font sizes down a bit, but that’s not a big deal.) This series, of course, has been spread out over days. The actual event covered two afternoon’s/evening’s. The first day was the attempted urpmi upgrade (which didn’t go too well.)

Disinfecting a PC… part 10
Before I get things wrapped up, I like to scan rinse and repeat until the scans come up clean. So, this scan of AVG gives a chance to delete the archive entry I mentioned the first pass it took. And spybot get’s updated from the internet and re-runs. All looks clean there… Ad-aware get’s an update check and runs again. Everything there looks clean now. The next thing to do is disable and uninstall tightvnc, I don’t want to leave bhodemon running at boot or the tea-timer from spybot now that things are fairly settled.
