REMINDER: WLUG BBQ
by Andy Stewart 18 Aug '02

18 Aug '02

HI everybody, The WLUG BBQ will be held on Thursday, August 22nd starting at 6 PM. Directions to Doug Waud's house, a.k.a BBQ Central, can be found on the WLUG website. Please RSVP if you plan to attend. I've received 3 or 4 RSVPs and I'm sure there will be more people than that. We need to have an idea how much food to purchase. WLUG will supply the standard BBQ fare and some soda and munchies. If you want beer or wine, you may BYOB and we'll have a way to keep it cold. Feel free to bring your own dessert or cold salad items if you so choose. Doug's house has a pool so bring towels and such! If you can think of anything else, let me know. Otherwise, I'll see you all on Thursday. Later, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

Kernel int-13 interface?
by Chuck Homic 16 Aug '02

16 Aug '02

Hey, this one goes out to all you kernel hackers out there. After 4 years, I've once again become interested in installing Linux on my HP OmniBook 300. Because it's an aswesome computer, and I think DOS 5 is a complete waste of its skill. [Background. The OB300 is a vintage 386-20, with a passive reflective 640x480 LCD display. Basically an oversize TI calculator running DOS] Anyway, from my first tests, I discovered that I can indeed boot the kernel using loadlin. But it immediately freaks out because it can't read (or even think about) my primary media... solid-state PCMCIA flash cards. Now, I briefly tried looking up some data on the OB300's PCMCIA chipset (I think the first standard was still being developed when this computer was made) and quickly decided that wasn't the route to go. And HP told me to go to hell when I asked. But DOS seems to work just fine using the int 13 interface to access the flash disks. So now my question... can I do that in Linux? I don't see any block device support (and most people would agree an int 13 block device would be stupid), but I think I can write one myself. All it would have to do is make the switch into real mode, call the int 13 interface, and then come back. Will Linux tolerate that? As far as I know, many drivers use a real mode interrupt on laptops to trigger their power saving capabilities (suspend, etc...), so I suspect it would be okay. Can anyone stop me before I go too far? Or should I go ahead and write this thing? -Chuck

potential mailing list problems
by Frank Sweetser 15 Aug '02

15 Aug '02

Just a quick heads up - the WLUG mailing list server seems to be having some issues, and since I won't be around to fix it until Monday, it may not be stable over the weekend. I have a backup of the mailing list data, though, so nothing should be lost once things are all fixed up. -- Frank Sweetser fs at wpi.edu, fs at suave.net | $ x 18 Full-time WPI Network Engineer, Part time Linux/Perl guy | Soitainly.

USB Support in Linux 2.4.18
by chuck 11 Aug '02

11 Aug '02

How can I tell if a specific USB device, in this case a removable USB hard drive, is supported by my kernel? I know that Linux 2.4.18 has "support" for USB devices. Does this mean all USB devices or just a few? I would think that the OS talks to the USB controller via a series of well documented commands and that its up to the controller to talk to the specific USB device. Does this make sense, or is there more to it? Thanks, Chuck

dhcp clients
by Brad Noyes 10 Aug '02

10 Aug '02

Hi All, I got my home network rigged up to do dynamic dns with dhcp. It seems that the linux and fBSD dhcp clients don't send the hostname to the dhcp server, so no name record is created for those clients. Does anyone know how to do this? (windows clients seem to send the hostname okay). Thanks, --brad

Wireless antennas
by Andy Stewart 09 Aug '02

09 Aug '02

HI gang, I have discovered that there are a couple of locations in my house where the wireless network does not work well at all. Naturally, they are the locations where I most want to use my laptop. My access point is on the 2nd floor in approx. the middle of that floor. I'm trying to use the laptop on the 1st floor at one end of the house to (almost) no avail. Moving the access point to other locations in the room seems to make little difference. My house is not a mansion - I'm well within the 300 ft alleged range. My 2.4 GHz wireless phones have no problem over this particular path through the house (and yes, I turned them off in case they were causing interference). I have been looking at these add-on antennas that are available on the Internet. It appears that some are passive while others are active. Would this help, or is there some more basic solution which I've overlooked? Thanks, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

Issues with aic7770?
by Keller, Tim 09 Aug '02

09 Aug '02

Has anybody done a Red Hat 7.3 install on a box with an Adaptec 7770 card in it? The machine was running *cough* the server version 4.0 of an OS that rhymes with "Empty" and working fine. However, when boot off the CD due to our buddy "El Torito" and INT13. The bios is able to get the diskette image but then unable to find the CD. I've got a ftp site with RH 7.3 so I point to it and everything works fine until I have to specify which driver I'd like to use for the scsi card. When I specify the Adaptec 7xxx series driver, the kernel issues an "Opps" and continues on. This machine is a 100mhz pentium HP Netserver. (yeah, I know its slow... I plan on using it as a standalone JBOD) Thanks, Tim.

NFS, anyone?
by Skip Gaede 07 Aug '02

07 Aug '02

Hi, I have a server running Mandrake 8.2. I had a problem unmounting a CDROM (I hate supermount!), so I rebooted the server. On the way back up, the NFS service hung. This is now the second time this has happened. (The first time, I attributed it to students messing with the server, and reinstalled everything.) Now, after two days of getting things back to normal, it's happened again, this time sans students. I'm writing this from home, as the school's link to the Internet is down. Anyone know where the relevant state data for NFS is stashed? Thanks, Skip

Pascal madness?
by desdinova＠soupforare.net 06 Aug '02

06 Aug '02

yeah.... I'm trying to teach myself pascal. What with the new release of Freepascal, and what with Delphi6/Kylix being out, I figure I should get something done while I'm out pounding pavement. Anyone know of any used book stores that have a decent computer section? I tried Another Story on Stafford St., but he didn't have anything for pascal. :( Any help is appreciated, Thanks James KB1FJQ
