Hey Gang, I might be at the next meeting! My wife and I decided to go off this month and spawn another daughter process. Olivia Keller was added to the global name space on Oct 7th. Later, Tim. -- I am weary of the allegiances of any politician who refers to their constituents as "consumers".

A REALLY nifty utility for making CD's and USB keys
by Karl Lind Oct. 17, 2008

Oct. 17, 2008

It's called Universal Netboot Installer and "UNetbootin allows for the installation of various Linux/BSD distributions to a partition or USB drive, so it's no different from a standard install, only it doesn't need a CD. It can create a dual-boot install, or replace the existing OS entirely. http://unetbootin.sourceforge.net/

Mythtv Hardware
by vze284qe＠verizon.net Oct. 16, 2008

Oct. 16, 2008

Hello all, I'd like to know what Wlug'ers are recommending for mythtv hardware these days. I already have a Hauppauge PVR-350 TV capture card. I'd like to build a low-profile quiet mythtv box that I can put next to a standard TV (not hi-def). What do people recommend? What about disk space? Ideally, I'd like something about the size of the mac-mini, but I don't think I can use a mac-mini as a mythtv backend. I already have a mythbuntu box, but it's big, noisy, and not suitable for what I'm looking for. Any ideas?? -- -Chuck

Hey all, I've got Ibex(Alpha) on my test notebook and I've just locked the display at 1024X768 at 60 HZ and I will be bringing it to the meeting.

Upcoming meeting - a potential topic - on Wed Oct 15th 7:00 PM
by Andy Stewart Oct. 13, 2008

Oct. 13, 2008

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI all, I was hoping that we could talk about the upcoming Intrepid Ibex release of (K)Ubuntu. I loaded this software onto my laptop, but unfortunately, I cannot get dual monitors working, and that means the projector won't work with my laptop in its current state. I've seen a lot of bug reports and complaining about this problem, but nothing that I've tried will make it work. If/when I do get it working, I'll bring my laptop to the meeting, but it is not looking promising. Failing that, as a backup, if anybody has a laptop that is running this software, and has its output VGA port configured for 1024x768@60Hz (and tested prior to the meeting!), and would like to lead a discussion, please let me know. Otherwise, I'm open to other suggestions. Note that whatever the topic, our meeting is scheduled for Wednesday, October 15th, at 7:00 PM. See ya there! Thanks!

SSH problems
by Eric Martin Oct. 3, 2008

Oct. 3, 2008

I have an outward facing ssh box at work that is currently being attacked. somebody's going through a dictionary attack of usernames; currently he or she is on abl. I can't block the IP Address because the ip is different with each username. Does anybody have any good ideas on how to stop this? I'm probably going to move the ssh port to some random high number to get rid of this, but I don't know yet if anybody else ssh's in besides me. Thanks in advance -- Eric Martin Key fingerprint = D1C4 086E DBB5 C18E 6FDA B215 6A25 7174 A941 3B9F

Funky LVM hack we talked about...
by Tim Keller Sept. 18, 2008

Sept. 18, 2008

Hey Gang, For those of you at the meeting who don't remember, Kevin had a 32GB flash disk that had a controller that had a built in understanding of FAT32. Thus formatting it as any other file system would work until you actually wrote to it then it would go insane. I postulated that one way to solve this would be to use LVM or MD, however when we tried this I hit a road block in that pvcreate won't let you pvcreate a regular old file, you need a device file, the same thing with MD. I finally managed to get it to work without having to hand add any devices into /dev... here's how... For my testing I created 4 100MB files using the command: dd if=/dev/zero of=part[1-4] bs=1024k count=100 This is what Kevin would need to do to on his flash drive... 1. Create 16, 2GB files on the flash drive named part[1-16] 2. Create loopback to file mappings using the command "losetup /dev/loop1 part1", repeat for all devices Also note, with this you could setup loopback encryption on these devices... If you suddenly find yourself without a loopback device issue the command in /dev "./MAKEDEV loop" However, I think udev will probably take care of it behind the scenes. 3. pvcreate /dev/loop1 /dev/loop2 /dev/loop3 /dev/loop4 ... 4. vgcreate vgHACK /dev/loop1 /dev/loop2 /dev/loop3 /dev/loop4 ... At this point if you issue a "vgdisplay" you should see how many (PE) physical extents you have. 5. lvcreate -n volume_name -l num_of_extends vgHACK If you use -L you can specify 300M, etc. Also you can specify how many stripes you want the data to be written in, which is handy if your 16 devices were on seperate disk controllers... Also you don't have to use all the extends in one logical volume, you could create lots of little volumes. 6. mkfs.ext3 /dev/vgHACK/volume_name 7. mount filesystem, sit back in bemusement that linux gives you the flexibility to do such things. Now... while were at it, if instead of LVM, if you wanted to use MD, this is what you'd do. If you have the lvm stuff from above, unmount the filesystem and issue a vgremove vgHACK it'll warn about active volumes, blah, blah... This command will take loop1,loop2,loop3,loop4 and put them into a 4 member RAID0 with no spare. mdadm -C /dev/md0 -l 0 -n 4 /dev/loop1 /dev/loop2 /dev/loop3 /dev/loop4 This command will create a raid5 out of the four devices without a spare. mdadm -C /dev/md0 -l 0 -n 4 /dev/loop1 /dev/loop2 /dev/loop3 /dev/loop4 It'll go off and build the array, now just format and mount and you're set to go. cat /proc/mdstat to see what it's upto. I was thinking of other insane things that Kevin can do with his 3 32GB flash disks. He could create 3 logical volumes each containing 16 members and then create an raid5 MD device using the logical volume members... He could create 3 16 member raid0's and then create a raid 5 out of them. He could install ZFS on top of fuse and then put all 48 devices into a zpool... I'll stop here, but I'm sure others have some even demented/funny ideas... Enjoy! Tim. -- I am weary of the allegiances of any politician who refers to their constituents as "consumers".
