Temp job opening
by Mike Leo 16 Sep '05

16 Sep '05

wlug members, I work for a health care company in Wellesely Hills that may soon be looking for a temp linux/windows sys admin. I am not sure if this has been officially announced, so I make no promises, nor do I decide who gets hired, so don't look for favor's, nor be mad if this is false hope. I just wanted to extend the information to the team. However, if you are interested, we might by looking for someone with 3+ years linux support (RH) and a 6+ year windows background. we have 380+ Windows/Novell/linux servers, and the linux piece is growing faster and becoming business critical...thus the need for this person. Being the senior linux person here, I want to dedicate myself to linux, which will leave a gap in the windows support. This new role would be to fill in that windows gap, and support linux with me, bridging the gaps in both areas. This will be only a temp/contract position. Typically the contract is for 3 months, but all other contractors here stay until they find perminant rolls (here or elsewhere). There are also other factors that will be discussed if you make it to the interview process. If interested in submitting a resume, please email me at mleo963(a)yahoo.com and I will put your resume in with our recruiter. Thanks Mike

Re: [Wlug] samba & symbolic links

Are you using Absolute links( ex /usr/share ) or Relative (ex ../../usr/share)? What apears as the link on the client? Does the link apear, or is it just a empty dir?

LVM snapshot questions.
by Adam Keck 13 Sep '05

13 Sep '05

Hello All, I have several questions about LVM snapshots. o Are snapshots persistent across reboots? If not by default, can they be made to be persistent? o How many snapshots can I have at once? o Is there some in-depth documentation out there on just the snapshot aspects of LVM? I spent about an hour googling for this info, but couldn't find what I needed. Why am I interested in this? Last year I took advantage of one of those occasional Tiger Direct ( shameless plug ;) deals to get myself a 200GB drive for 50 bucks. I am using the drive to backup my machines. Right now I backup once a month by copying the user data from my iBook, my wife's iMac, and my Knoppix laptop to the drive. Each time it comes to about 15GB total. I am beginning to fill the drive, so I want to design a more efficient way of using it with OSS tools. My plan is this: o Acquire a cheap used PIII pc. Install the 200GB drive and Centos (for familiarity's sake, RHEL is one of the distros I use at work) o Make an LVM partition on the drive. o Designate half the drive to data and half the drive to snapshot space. o Rsync every machine weekly. Prior to each rsync, snapshot the drive. o Keep as many snapshots as will fit. Presumably this will be many more "full" backups that I can hold than by just copying stuff to the drive outright. I am downloading Centos right now to test this scheme. I thought I would ask while I wait for bit torrent. Has anyone tried something similar to this? -Adam

samba & symbolic links
by Bill Mills-Curran 13 Sep '05

13 Sep '05

I have a linux server that's exporting a samba share at a windows-dominant site. In a directory of the share, there's a symbolic link to a different (non-shared) partition. (We had to move a directory due to space limitations.) Windows clients can mount the share and follow the symbolic link. My fedora-3 client can mount the share (smbmount), but cannot follow the link. I seem to remember that a RH 9 client would follow the link. Any idea what's going on? Thanks, Bill

workspace selection by app?
by Bill Mills-Curran 11 Sep '05

11 Sep '05

Is there a way to have an application start in all gnome workspaces? For my particular need, I am using xmessage to inform me of specific events on my machine. To make it harder to lose track of the xmessage (pop-up) window, I'd like it to display in all my workspaces. I figure there's some magic setting in gconf (or, even better, an X display setting), but I can't find any documentation on it. Any ideas? Thanks, Bill

Re: Wlug Digest, Vol 23, Issue 4

Hi, Based on one of our post-meeting pizza discussions last night I thought I would send an e-mail (something I do so rarely). Here is a site that has a good selection of WIFI gear (APs/amps/antennas). I have never ordered from them but they appear to have a good selection of radio gear. http://www.fab-corp.com/ A few ideas to remember: 1) A stronger omni directional antenna (greater db numbers) will improve both your transmit and receive and both are important for range for WIFI. 2) Directional antennas must be aimed at the other radio. You get more gain, but they are usually not the solution if you want to wander your house/deck/yard with the laptop. 3) Amplifiers have downsides; 1) another device to power 2) another device to fail later 3) a good one runs around $200 with both transmit amp and receive pre-amp. 4) Antennas are rated in decibels (db). Most antennas on access points are round 3db - 5db. In terms of signal strength an increase of 3db is a doubling of effective power (Ex 3db to 9db is roughtly 400% stronger). 5) The weakest link in WIFI is usually the card and particularly the internal antenna in the laptop on the far end. 6) You do not succeed unless both devices can both "transmit" and "receive" the other radio. 7) Selection of a feed cable for an external antenna is VERY important. At 2+ghz frequencies a long cable (>1 foot) or a poor quality cable will loose everything you are trying to gain with a better "numbers" antenna. >From a local computer AND radio geek, Joel Desrochers

Reminder: Upcoming Meeting
by Andy Stewart 08 Sep '05

08 Sep '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, We have a WLUG meeting scheduled for Thursday, Sept. 15 at 7:00 PM in the Access Grid room at WPI. I'm not sure of the topic, but if nothing better turns up, I'll start babbling about my most recent USB experience (which started unpleasantly but ultimately had a happy ending), and we can segue from there into whatever topic people wish to discuss. Bring your Linux problems and try to stump the audience. :-) I'll bring my iAudio G3 MP3/Ogg player since a couple of people said they wanted to see it. I had hoped to have it at the last meeting but it wasn't shipped to me in time. Naturally, we'll go out for pizza after the meeting. We can discuss the insanity of looting televisions during a flood crisis, the possibility of adding anti-DRM language to GPL v3, and whatever else we find interesting. See ya then!

SuSE dual frustration....
by Adam Keck 05 Sep '05

05 Sep '05

Hello All, I am trying to install SuSE 9.3 on a dual dual-core Opteron system. I can boot into the installation kernel and do an installation, but when the system reboots it boots to a black screen with a ~2 inch horizontal green line in the upper left-hand corner. I am not sure where to start troubleshooting this, since I do not have much error output. The things I know so far: o Knoppix 3.9 boots fine and runs off CD. o SuSE 9.2's installation kernel boots to the same state. o My install of 9.3 was a basic "click next" install. o http://www.beowulf.org/archive/2005-July/013234.html indicates there may be some issue with the initrd, but does not say what the guy did. My impression is that I am not even getting that far, though. Any help/hints/direction would be much appreciated. Thanks very much! -Adam
