Linux

export _POSIX2_VERSION=199209 To install some old Loki Linux games you will need to set the POSIX version. Here you go Intertubes for all to search and find.

As many of you know, multipath was finally integrated into Redhat Linux with the 5 series. This is great when you have multipath enabled during an install as you will see /dev/mapper/mpath0, but what happens post install when you attach new LUN? Here is the howto for what happens behind the scenes during a RHEL install: After the filer has attached and presented the new LUN reboot the machine allowing for the HBA card to recognize them Post-reboot login and verify with the drivers are present with the correct capacity: dmesg | grep sd Next we need the WWID for the new path. For this example assume that sdh is one of our newly presented multipath drives: scsi_id -gus /block/sdh Copy this output down and have it ready to input into a config file. I recommend pipping or copying down the results withing GNOME/vim Edit the /etc/multipath.conf with your editor of choice and look for the blacklist exception list. You will see a WWID “923847089123908u2389” already listed. Copy that line and replace the “218934708912374” with the output of command #3 Reboot the box After the reboot login and cd /dev/mapper and verify that there is a newly listed mpath1. If this is not the case stop what you are doing and wash-rinse-repeat steps 1-6 If there is a mpath1 we need to create a new partition. Since Linux sees the device as a new block, use fdisk as you would with any other drive: fdisk /dev/mapper/mpath1 Since the drive is freshly paritioned you will need to reboot to allow the kernel to recognize the new parition table. Post reboot we can create a filesystem. I am going to assume you created one parition and are going to use ext3: mkfs.ext3 /dev/mapper/mpath1p1 Next edit your /etc/fstab and point the new drive to a path you want the new mapping mounted to: /dev/mapper/mpath1p1 /storage ext3 defaults 1 1 For the next portion I will operate under the assumption you are attaching more storage to your /opt directory for a new commercial install. As root drop to run level 2: init 2 This is the lowest run level where the / filesystem is mounted r/w and multipathd is running We will move /opt as it is current substatianted to /opt2: mv /opt /opt2 Create the mount for the SAN LUN: mkdir /opt Mount the LUN: mount /opt <–read from the /etc/fstab entry Now we sync the directories with rsync: rsync -avh /opt2/* /opt I recommend holding onto the /opt2 until everything is tested after a reboot Done!

Here is a blast from the past…way back past… I loaded OpenSuSE 11 on my G4 Cube and remembered I had a few of the old Loki Games. Here are the games with ports to Alpha/PPC/SPARC: [Civilization: Call to Power ](http://en.wikipedia.org/wiki/Civilization:_Call_to_Power) Myth II: Soulblighter Railroad Tycoon II Eric’s Ultimate Solitaire Heroes of Might and Magic III It is mind boggling that at this point in Linux history (2000-2002) that someone decided to port these! The great thing about GCC and SDL is cross compiling is pretty simple. With that said supporting these must have been a nightmare for Loki.

I wanted to run MacOS 9 in my Ubuntu Intrepid dev box so I went ahead and grabbed CVS. Problem was the autogen script never dumped a config.sub. Instead I took the easy route and downloaded an RPM version and used alien to convert. The one extra step to get it running is to as root ln -s /var/lib/libreadline.so.5 /var/lib/libreadline.so.4 Have fun! sheepshaver_23-13_i386.deb
