I was just looking through my archives and remembered the Golden Apple Project. Ahhh yes. Well it turns out that the machine was so old it just stopped working altogether. OpenBSD was running just fine on it, but after a year the network card died and when I tried to add a netgear PCI NIC it caused kernel panics. I do have a new apple PPC machine that I have been prepping to handle light duties, her name is aphrodite and she’s a little red iMac. It’s my hope that I can keep at least one PPC box running unix in my little computer family…
Ever see this?
dhcpd: uid lease 192.168.1.150 for client xx:xx:xx:xx:xx:xx is duplicate on 192.168.1/24
or something like it, in your dhcp logs? Well I checked /var/log/messages today and saw that I had thousands of this message repeated over and over (so much so it was spamming my log and making it harder to find what might be important stuff). I searched around the ‘net and found some hints but nothing conclusive. The hints pointed toward a duplicate lease (duh) but more specifically lead me to check my leases file. Mine was located in /var/db/dhcpd/dhcpd.leases.
It turns out that what caused this error for me was that I had started the machine in question (the MAC address has been altered to protect the innocent haha) before I had the time to create a reservation for it. Then after it already had an address leased to it, I created a reservation for it (for internal DNS purposes, nothing more). Apparently because duplicates are allowed by default in isc dhcpd, when the machine’s networking was restarted and it got it’s new reserved IP, the server kept the original lease (which was that .150 address) and also got a lease from it’s reservation (.80 on my network). Since the .150 lease was still present in the leases file it caused the warning message (over and over and over for a month).
So if you are using isc dhcpd, and you use reservations, and you’re getting these error messages, you might want to check your leases file and make sure that you don’t have a lease for something that also has a reservation under a different IP.
The other pages I found on my search also suggested that you might have a reservation that hands out an address that is within your dynamic scope. You definitely don’t want to do that, so you may need to check that out as well in your dhcpd.conf.
For the curious, I run FreeBSD 7 on a Pentium 4 Dell desktop (I think it’s a dimension series, I haven’t looked at it in a while haha) that sits in my kitchen as a headless DNS/DHCP/Web/Random Unix Fun server. It’s actually making lots of bad noise lately and I think one of it’s fans might be going 🙁 I’ll check that out and report back 🙂
What follows is a rant/review of Yellow Dog Linux 5.0.2. It’s the second part of the “Golden Apple Project” article series, which tells the tale of my quest to transform a formerly unused Apple PowerMac G4 (450Mhz, AGP Video) into something more useful than an unused OS 9 machine.
After a somewhat discouraging attempt at installing NetBSD (see the first article in the series), I decided to try the OS that first showed me how nice the PPC architecture is for Linux – Yellow Dog. I figured that since Yellow Dog was great when I tried it about 2 or 3 years ago it would be even better now, especially with all the support Terra Soft has been getting from Sony. What I found, however, was that YDL was not quite what I had hoped. In fact I was very disappointed.
When I install an operating system I look for a few basic things, the first of which being a quick and reliable way to install. I’ve installed several operating systems and several distributions of Linux and so far Yellow Dog is the only one that requires either a 3+GB DVD or 6 CD’s to install. 6 CD’s and every one is required? That is simply insane. What if I just want to try the OS for a while? What if I only need a minimal system? What if I don’t have enough hard disk space to install every application under the sun? Yellow Dog Linux was not designed with these “what if’s” in mind.
After a few unsuccessful attempts at downloading the DVD ISO image (each attempt stalled at or near 2/3 completion, which is not YDL’s fault but still not fun) I decided to get all 6 CD images burned instead. At least this way I would be able to download the distribution in smaller chunks. I thought that since I already downloaded everything that the install would go fairly quickly. I was wrong. It took about 2 and a half hours to install from the CDs. Granted, it’s an old 450Mhz machine with a slow FSB and 256K ram, etc. but still – 2 and a half hours is a long time. I moved forward though… swapping discs when asked and watching anxiously as the installer showed me that it was copying package after package of open source software (none of which I was allowed to choose or not choose).
When I tell you I watched anxiously, I am being very literal. The install process consisted primarily of watching the installer. It didn’t ask me any questions. It didn’t let me make any choices. It only prompted me to insert CD after CD. After disc 6 I was finally asked for the root password and was invited to create a user account for myself. I expected to be asked for some networking information at least, but was not. Root password and user account name and password. That’s it. I tried to tell myself that it was a hassle-free install (again since I don’t count the download as YD’s fault, really), but I couldn’t get over the fact that there was no way to configure the network during the install. Normally I would configure the network first, and use it to install the operating system over the network via FTP or HTTP. With YDL network installs are not an option but I would have liked to have my network configuration done before first boot.
So far YDL had already been an unusual experience, and I hadn’t even gotten to first boot. As the machine restarted I told myself that the worst was over and that after I logged in and configured the network everything would be fine. Wrong again. I logged in with the user account I created during the install and saw a very nice looking E17 desktop. I must admit – E17 is coming along nicely. The only word I could use to describe it right now is… pimp! hahaha 🙂 I mean wow. It’s one gorgeous desktop. Kudos to the E17 team. Unfortunately however, this desktop was basically for my viewing pleasure only. No program would start that was not already running for me, neither from a launcher, nor a menu. Not even the “run command” box worked for me. Seems the user account was running as a different user than X and had no permission to the display. Nothing would work as the regular user except logging in and logging out. The word that best describes this is LAME. If you are keeping track of the adjectives so far you’ll see that the negatives outweigh the positives already.
At this point I had basically lost faith in the YDL distribution. I have seen desktop Linux come a long way over the past few years and YDL took me back to a time when I could undoubtedly expect more problems than ease with Linux. Yet, I logged in as root just so I could at least take a tour and see what all of that downloading and waiting and watching would get me.
As root, launchers worked and the menu too. Firefox started and was very responsive, even with the limited resources. Even OpenOffice’s writer and spreadsheet programs worked fairly quickly. I was reminded that the PPC architecture is great, even without OS X. This moment of happiness was short lived – I found out soon after opening Firefox that there was no flash support for Apple PPC Linux. There will most likely never be official Adobe Flash support for Apple PPC Linux. That saddens me but not to the point where I’m going to give up on the whole project.
I looked around some more and found some more things I didn’t like (while trying to find things to like). Apache came pre-installed and so did Java and Python. PHP and Ruby were left out though, and those are my two favorite languages to code with. Some Gnome games were installed, but not Gnome sudoku (which is awesome, btw).
In summation, if you add up all the adjectives you get this – Yellow Dog Linux on Apple PPC is a disappointing, lame, pimp (remember that E17 is PIMP). A disappointing lame pimp that saddens and frustrates the user, but looks so nice. What else can I say? At least it’s better than OS 9? I’m not sure I can even say that. I guess any Linux is more fun to use than OS 9… but a crippled desktop is a crippled desktop, pimped out or not.
So where does this leave the Golden Apple Project? To paraphrase the beautiful Joss Stone… My hopes for this old PowerMac G4 are “Bruised but not broken”. I’m going to try OpenBSD… and I have plans to revisit NetBSD as well. There is no giving up on this quest! Stay tuned…
The other day I acquired a hardly used PowerMac G4 from someone who was going to throw it out. Imagine that? It’s got a 450Mhz PPC CPU, 256MB of RAM, a 20GB hard drive, and AGP video. Certainly this nice little machine can be used for something… But what?
Though I could probably get away with an install of OS X Tiger, I knew in my heart that it would be wrong to use the Tiger install disk that I have to install it on a second machine. Actually I just thought it would probably run too slow, but hey it’s still illegal and that’s not how I do things… right? Right. So it was just a question of whether it would be Linux, NetBSD, OpenBSD, or some other free OS. I decided to try NetBSD first.
NetBSD has supported PPC for a while, just one of the many architectures supported by the ultra portable BSD. The story here is fairly short and somewhat funny – I was able to install the OS but never figured out how to get it to boot. Lesson learned: Knowledge of Open Firmware is essential when you’re dealing with an Apple PPC machine like the PowerMac G4. I found this site and this site to be helpful, as well as the install notes for NetBSD. Oddly though, even following the notes to the letter I was unable to boot the OS. I gave up after seeing that my Open Firmware 2.4 system might not be supported at all due to what might be a “broken” Open Firmware. In hindsight I think I was just using the wrong device designation in my boot command. I might try it again.
In part II of the Golden Apple Project I try out Terra Soft’s Yellow Dog Linux. Which operating system will win the right to run on my shiny old G4? Stay tuned to find out!
I forgot to mention that I wrote a review for a book about designing BSD rootkits. You can find the review over at Daemon News
