samba & symbolic links
by Bill Mills-Curran Sept. 13, 2005

Sept. 13, 2005

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 Sept. 11, 2005

Sept. 11, 2005

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

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 Sept. 8, 2005

Sept. 8, 2005

-----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 Sept. 5, 2005

Sept. 5, 2005

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ...what do you all propose for a topic for the Sept. 8 meeting? More importantly, does anybody want to do a presentation or lead the discussion? This month, I've been debugging USB problems on my server, and I think I may have made some progress on USB 1.x, but not on USB 2.x. I'm not sure if this is a meeting topic - howto get stuff to work on USB and how to debug it if it does not. Your thoughts? Thanks!

I've been a bit leary of all that. I've done software RAID (RAID0 and RAID5) for a long time and never had to use an initrd image. Just have a 100 MB boot partition on one drive, and set root=/dev/md0 in grub. This is with two 60GB WD HD's and one 80 GB (which has the bootable 100 MB partition). If you RAID it all, well, guess you need an initrd (please correct me if I'm wrong). As far as RAID1 and RAID5, isn't RAID5 strictly better, if you have the HD's? I mean, just lose 1/3 of the storage for total mirroring and you have to lose 2 HD's to lose your data. Why would someone choose RAID1 over RAID5 (just curious)? I did have a RAID5 system set up, but decided to change it over to RAID0 and use an external Maxtor drive for backup (just simple rsync). > Now that would be a good meeting some evening, talking about and > showing how to setup a bootable RAID system for the OS and how to > upgrade your kernel easily and automatically. Personally, I feel if you compile a couple of kernels it really becomes old hat, I mean, once you know how to do it it's no big deal. Same with RAID systems. But that would be an interesting meeting, nonetheless. > Let me rephrase your reasoning: You don't want to use an initrd because > you aren't familiar with the process. Just because you do a lot of kernel > builds/reboots (and your definition of a lot is my definition of very few, > here), that is no reason not to use an initrd. I've never had a problem and found I needed initrd to get something to work. What are the benefits of using it? - Carlton

Thanks! actually i have a 66mhz card i was using in a raid, but i dont need it anymore since ive dismantled said raid, so you're welcome to it i forget exactly what it is, but linux-2.4 and linux-2.6 have drivers for it and they seemed pretty solid -mike _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug
