Stupid Hardware Clock Tricks, aka: WTF?

by Theo Van Dinter

Over this past weekend I upgraded my server from a P200/RedHat Linux 7.2 to a new Athlon 850/RedHat Linux 7.3. The Athlon was my trusty workstation for many a year. Everything's great, except for one problem: the clock goes crazy! It seems to be a once per second issue: $ perl -e '$t=time;while(1){$t2=time; warn join("\n",scalar localtime($t),scalar localtime($t2),"") if ($t2-$t>4); $t=$t2;}' Wed Aug 21 17:17:28 2002 Wed Aug 21 18:29:03 2002 Wed Aug 21 17:17:29 2002 Wed Aug 21 18:29:04 2002 Wed Aug 21 17:17:30 2002 Wed Aug 21 18:29:05 2002 I use netsaint to monitor system health, and it keeps complaining about the time jumps: Aug 21 18:28:03 eclectic netsaint: Warning: A system time change of 4296 seconds (forwards in time) has been detected. Compensating... Aug 21 17:16:31 eclectic netsaint: Warning: A system time change of 4293 seconds (backwards in time) has been detected. Compensating...

Aug 21 17:18:10 eclectic netsaint: Warning: A system time change of 4293 seconds (backwards in time) has been detected. Compensating... Of course, random checks start failing as well since they occasionally run during the time jump, and if they're checking for time since something occured (log entry, cron run, query response time, etc) ... I've tried "hwclock --systohc" to force the hardware clock to the same time as the system, didn't help. I'm running NTP and thought maybe it was having problems, so I tried turning that off, didn't help. I went through BIOS and tweaked memory/IRQ settings -- I didn't think it would really solve anything, but the setting changes and reboot kept the behavior away for ~14-15 hours. So I'm completely stumped as to what causes this problem. Has anyone seen anything like this before? Any suggestions for things to look at? I'm at the point where I'm planning to just buy a new bit of hardware, migrate the drives and such again, and go from there. With my luck the problem would follow me of course... :( Thanks in advance. :) BTW: If anyone is wondering, I'm running SGI's XFS patched 2.4.18 kernel: 2.4.18-SGI_XFS_1.1. I'm thinking about dropping back to a 2.4.9 kernel w/ XFS support and seeing if that works any better. :( I was running 2.4.18 on the P200 for quite a while though without problem. -- Randomly Generated Tagline: I don't want to look like a weirdo.

REMINDER: WLUG BBQ

by Andy Stewart

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

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

USB Support in Linux 2.4.18

by chuck

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

That way the client can choose it's own DNS name, and tell the DHCP server to set the PTR record to that name (since the DHCP server will have the authority to update PTR records in the subnets it is serving).

These behaviors are controlled by the DHCP FQDN option (82). The client can request that it update the forward DNS, or request that the server update the forward DNS. The server can either accept what the client requests, or reject it. If the server rejects the client's requests for the client to update the DNS, the client should not attempt to perform the update. ISC DHCP supports the standard form of DDNS described above (unsecure updates or TSIG security only). You can't update Windows DNS servers securely with it. You can however update Windows DNS servers if security isn't configured, or you can have a Windows DHCP server update so-called "legacy" clients without using the DDNS protocol above. Having never used Windows DHCP/DNS servers, I wouldn't know how to configure that... To have the ISC dhclient perform DDNS and update it's own A record put this in dhclient.conf: send fqdn.fqdn "foo.bar."; send fqdn.encoded on; send fqdn.server-update off; Change the last option to "on" to request the server to update the A record.

Re: [Wlug] Wireless antennas

by RB

Andy, Passive antennas work best when there the signal is low. It usually won't do a whole heck of a lot if the signal isn't there to begin with. I've done a couple of installations where I've used multiple antennas located in different parts of the building. The Linksys systems use two antennas for diversity reception. I've taken one of them and attached it to coax and an antenna and placed it in the "problem" room. It will reduce the overall range somewhat (since you'll lose your diversity reception capabilities) but it will fill the area you want the signal in. If you want to you can also put another antenna in a second "problem" room. This would of course change the center of your coverage area but if the antennas used have high enough gain to overcome the coax loss then you may actually gain some range in certain directions. The whole key is to put the signal where you want it. You'll sometimes trade off your signal in one location to improve it in another. This isn't always a bad thing. - Rob On Thursday 08 August 2002 11:04 pm, Andy Stewart wrote: > 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.

The catch with these add-on antannas is that they get you more effective power by limiting the direction in which they're broadcast. If you can find one corner of the house, you should be able to get away with an antenna that has just a 180 cone, instead of a full omnidirectional one, that will give you twice the effective signal strength. Also, if you access point has dual antennas, then you can leave one as the omnidirectional, and get a directional for the other antenna and point it at the problem spots. -- Frank Sweetser fs at wpi.edu, fs at suave.net | $ x 18 Full-time WPI Network Engineer, Part time Linux/Perl guy | Right now I'm having amnesia and deja-vu at the same time.

Wireless antennas

But, your original point is moot because he has since made it clear he needs a book on Borland's version of Pascal, which isn't Pascal proper. >I don't think K&R ever wrote anything about C++, that >is Stroustrup's baby (or bastard). Correct.

WLUG BBQ!!!

by Andy Stewart

Hi Everybody, Although I have not yet updated the WLUG website, the WLUG BBQ is going to happen! The BBQ will be held in Shrewsbury at Doug Waud's house like it was 2 years ago. Directions are forthcoming. Thanks, Doug! Our next meeting of WLUG will be at the BBQ on Thursday, August 22, 2002. The BBQ will start around 6 PM and go until Doug kicks us out (watch it, he has Steve as his bouncer). If you can't make it at 6 PM, show up whenever you can. WLUG will supply the food and munchies and will have sodas on hand. You may BYOB (beer, wine, whatever) if you wish. If you would like to bring a salad or dessert, feel free! Label your container with your name to insure its return. Doug has a swimming pool which we can use, so if you are interested, bring a bathing suit and towel. Its not clear to me if one must actually *wear* the bathing suit. We'll rig up some kind of projection system for a LInux talk of some flavor. It may end up getting used by some of you ASCII Art fanatics, but that's OK too. ;-) What good would a Linux party be without an Internet connection, a projector, and a laptop or three? Please RSVP to me and let me know that you'll be coming. In this way, we can be sure to have enough food on hand. Other party ideas? Send them out to the list!
