What's needed is that the first sector understands LVM (or whatever the file system is if there's not LVM). So if we put the root onto a "conventional" file system, the first sector would be the boot code - no GRUB/LILO or anything else needed (IIRC). Of course, then no parameters passed, no selection of alternate boots, etc. Just like the old days! :-) Simplicity has its strengths and weaknesses. > -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I don't think that's related. > work, with other video cards and chips, so I suspect the problem is > with the nv driver that got installed with the OS. I doubt that. Before I started using the rpmforge packages, I used the box-stock ones w/o problems. I suspect that running it from a X session is related. ISTR that in some other thread someone mentioned some CLI stuff specific to Gnome could be used, but I don't recall them. I _think_ the normal GUI display configuration stuff just modifies configs for the desktop manager. I _suspect_ they would not update xorg.config. System-config-display does that and AFAIK has no problem. But, as mentioned, I never ran it while X was active and never used --reconfig. I also _always_ visually inspected the results and modified them to suit my taste: reduced the number of modes, added more color depths, filled in missing DDC info, etc. As to the rpmforge units, my _perception_ is that things work a little faster with those drivers. The stock nv driver is ok, but a lot of folks have commented about increased utility with the nvidia drivers. They usually installed from source. Since rpmforge now has rpms for both the older and newer drivers, no need to roll your own. You'll need to get card ID information so you know if you need the older or newer drivers. E.g. $ /sbin/lspci|grep -i nv 01:00.0 VGA compatible controller: nVidia Corporation NV18 [GeForce4 MX 4000] (rev c1) >From X.org.log (--) PCI:*(1:0:0) nVidia Corporation NV18 [GeForce4 MX 4000 AGP 8x] rev 193, Mem @ 0xe800/24, 0xe000/27 If you just acquired the card, probably the newer package is what you want.

That taught me long ago, if input was inconsistent, to check for
non-numerics before doing math. Back then, it was the expr command
(still available I think). Now it's some of those builtins accessed with
${} constructs. Expr is simpler, shorter to code and reliable.

I had an LFS system I built long ago and added CentOS to it. It could be booted from either HD. I forgot to change my root= stuff in fstab when I finally converted fully. Took me awhile to figure out why changes I made had no effect on booting.

Glad you discovered the _symptom_ of the raid problem. However, I'm _totally_ ignorant_ about raid. I suggest you 1) search the archives for stuff about raid and 2) start another thread describing your raid issue. There's a _lot_ of folks on the list who are expert with lots of types of raid. What I think I recall from the threads I've seen (I don't know if this is generally applicable) is that the HD be partitioned for 2 approximately 100GB partitions to be used as boot and the rest defined for raid. Some suggest that all of the "rest" be an LVM partition for ease of management. But, as I said, I'm not knowledgeable, so do start another thread about your raid concerns after searching the archives. You should find a lot in there. > -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

"I have not been able to connect to rpmforge for a couple of days" This one I guess. I understood that he could not connect to the web site.

I see that _your_ post to rpmforge's list got through ok and the web site was apparently not fixed at that time, based on Dag's subsequent post.

IIRC, Non-Maskable Interrupts are ones that must be dispatched immediately, not queued for handling. Hardware events that cause these interrupts, IIRC, include the hardware clock, HDs, serial devices, etc. Thinking just of the hardware clock alone you can see how NMI counts would always be increasing. I'd suggest doing what Nate did: look at some other systems to see what happens to their counts over a brief time and see if yours looks reasonable.

A simple thing I've done is to use touch to make a timestamp file just before running the process. Then a find command check for files or directories that have a modification time later than the timestamp file is used. I think the parameter is "-later"? Use the man page to confirm.

You want to have NOT checked the check now and/or make it the default. Gnome has a script that can set this. Someone else posted it in another thread, but I can't remember it. Also, the Gnome menus System->Preferences->More Preferences->Preferred Applications->Web Browser can be used to set it. Once you select Firefox, the command box should have "firefox %s". Once this is set, starting FF should make a new pluginreg.dat if you removed the previous one, IIRC.

At best, they'll have circuitry/software on-board that accepts either a straight-through or null and adapts itself. Being an _old_ telecom guy from way back, I prefer what was called a symmetrical null modem fully configured.

There might be a second on the main board that is accessible via a header. If it's not hooked up disable all but the first in the BIOS (later). It's not really hurting anything as is, but it will free the I/O address and IRQ for assignment to other devices. But wait until you have things working - I suspect you have _two_ ports (probably 1 9 pin and 1 25 pin). A second port of 25 pins might easily be mistaken for a printer port. Long ago a switch from Centronics style to RS-232 style began to become the "standard". Physically, it looks the same as a serial port, the visual difference being the "gender" of the connector will be opposite. > Feb 26 12:12:25 borg2 kernel: 00:05: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A > > Is this what I'm looking for?

I did look > at the man page, too, but not knowing what I was looking for didn't help. I haven't used it for a _long_ time, but IIRC there is an interactive menu system that works with some keystroke, maybe key. Look for that stuff in the man pages and it should be clear sailing. First, have you set the baud rate correctly? A lot of things used to default to 9600, but 38400 became common later on. Do the docs for the unit specify? If so, use the stty command, or in minicom or other terminal emulator it's method, to set the baud rate to that needed. Usually these days, no parity check is done so 8 bit characters should be OK. Now, since the port is recognized the failure has to be from the port onward. If the RS-232 9 or 25 pin shell is connected via a cable to the main board, make sure that the cable connector is connected to the right header on the main board. Since Linux reported two ports, there should be two headers on the main board (_if_ that's the method - some ma inboards have them mounted directly on the main board). If the header/connector is not keyed, it may be connected backwards. If you have two RS-232D shells (9 or 25 pin) you may be connecting your cable to the wrong one. Moving on, have you been able to verify the cable is good? If you have an RS-232 patch device with LED's, you can see activity (DTR, DCD, etc.) by hooking the cable to it. If you don't have one of those, a digital multi-meter can be used to see if you have expected voltages on certain pins (+/- 12 volts, IIRC). If you don't have one of those, a plain old dumb terminal can be hooked up and settings changed in a trial and error method. Since they supplied the cable, is it new enough to assume that it is not damaged? If so, I suspect something easy like baud rate. > > Anne > HTH -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I remember those - and the 25-9-pin adapter :-). > Peering around the back in a dark corner, I could well have been mistaken. > OK - female socket, so that's a COM port, I think. To be politically correct and eliminate ambiguity, we'll change the terms here. Socket (formerly female connector) on the computer s/b a parallel printer port. Almost always a 25 pin in the past, but I've not kept up with that stuff over the years. Plug (formerly male connector) on the computer s/b serial ports. On the cable, this is reversed, of course. Now if the cable has RS-232 on both ends and is not a fully symmetrical null modem cable, it will make a difference which end is connected to what. Make sure your cable socket end is what's hooked to the computer. Often the cables will be labeled which end goes to computer or device. Sometimes cables have the same gender on both ends. If they've done that you could just have the cable reversed (presuming it's one of the asymmetric cables). It's not uncommon for a null to be made by jumpering certain pins on just one side of the cable and crossing 2 and 3 end to end. > > Now I'm really confused. The BIOS definitely only shows one COM port. To be Ouch! Since I've not kept up with this stuff I can't sat if there are other new devices which use 16550 serial drivers. _But_, there are definitely 2 ports as the detection routines must write to the ports and read status to determine if it's a 16450, 16550 and revision A or not (the original 16550 had insufficient buffer IIRC and the A had to be issued to prevent overflow at higher speeds. CPUs "back in the day" were just to slow to handle the interrupts quickly enough). My guess is that your BIOS has a "menu" in the legacy devices area that has a drop-down or scrollable menu to select which port to configure. In there you can enable/disable, change default I/O and IRQ settings, etc. I think you'll find a second port defined. Which raises the possibility of the computer's connector being on ttyS1 instead of 0. But I suspect if you check the back of the computer you might see two plug connectors. These should be the serial ports. In today's world, probably 9 pin. > > honest, I can't remember whether I connected it or not.

Yes. My intent was to debug the computer side first. With a terminal
hooked up, you can echo directly to a ttyS{0,1,...} some short line and
see if the characters are readable. Whne that is achieved, looking at
the terminal settings will let you know baud, parity stop bits, flow
control (possibly), etc.
Once you know what one side of the cable is doing, then one can proceed
to the other device. Divide and conquer.

Oh, the AVM B1 worked too, if you have ISDN. The Courier was designed and released before the 3Com buyout, IIRC. I have one of those and it was great until lightening apparently got it. By then 3Com had the company and the repair cost they wanted (exchange program I guess) was _way_ to high. It's still sitting in a corner awaiting a decision (umpteen years now).

In my experience docs are often not updated when a minor design change is made to hardware. But there is another possibility ... What chip set on the mobo? Many chip sets include dual 16550A support and the mobo manufacturer, to save a penny or two or space or ease circuit trace design, might only provide a pin-out for a single port. A review of the chip set specifications might confirm this. Then a visual inspection of the mobo, or a look at the layout in the manual (if you can rely on that at all) might confirm.

The basic thing to know about vi is that it has three modes. Input, replace and interactive. Default on startup is interactive. From here you can switch modes, move around in the file and search for things. The most common interactive stuff is moving the cursor around with the arrows. If you're more comfortable with them, regular letter keys can accomplish the same movements. I tend to use them as they do not depend on proper terminal definitions being available (hangover from the old days when I worked on lots of different systems and terminals). Another common interactive function is searching for stuff. Without getting into regex, a slash followed by some text and a slash or finds the next occurence. Repeat as needed. Replace the slash with ? and it goes backwards (up the file). Scrolling through the text file can be done with , , and keys. There's also standard keyboard letter equivalents. Once positioned, you can enter input mode (which also includes replacement of text if desired). Hitting the key will insert characters at the current cursor position. Hitting it a second time replaces characters. Toggle by hitting as many times as needed. To exit either mode use the key. To insert a line before or after the current one, O or o (that's "oh", not zero) for "Open before" or "open after". I'll leave it to your "man vi" excursion to notice the "i", "I", "a", "A" meanings and some of the equivalents to which I've alluded above. Another useful function is the yank and pull functions. Keep an eye out for them. Marking lines with the letters, e.g. ma, mb, ... is also quite useful for setting a "bookmark". Used in conjunction with the t (copy) or m (move) commands, it can save a lot of time. ":w" writes the file (suggested for frequent saves), "ZZ" writes and quits, as does ":wq". Notice that ":" puts you in "command mode". Lots of possibilities there, like changing the file name, splitting the screens, switch the active window, reading in another file, etc. Read small sections, test what you read to reinforce your memory and you should get it quickly.

It used to be that the manual for all the UPSs I've used said to _not_ plug it into a surge suppressor, IIRC. Has that changed? It had something to do with the wave form from the suppressor vs. the box's monitoring circuitry. I don't think that has anything to do with not shutting down though. > power to the UPS.

Is there some basic guideline on > how many to remove? I suspect you have a minor mess-up in /etc/yum.conf (man yum.conf). IIRC, installonlypkgs (defaults to various kernel name variations) interacts with installonly_limit (default 3?). Somewhere, I can't recall where ATM, when the Xth version, specified by installonly_limit, is exceeded the oldest package version is automatically removed. However I seldom play with this stuff and haven't reviewed it in a long time so I'm unsure about this. I do know that the grub.conf (menu.lst) is automatically updated to remove the older versions. Maybe I'm confusing the two? Let's hope one of the folks that are current and more expert will chime in. Now, if you made the mistake I once made, this all breaks. I had a fall-back boot scheme set up that had a second disk bootable and a copy of root, /var, etc. on it to allow fast recovery (LVM snapshots were automatically created at various times to complete the process). I then set that backup boot disk's /root into my fstab and forgot to remove it after testing. Yum updates ran on it and never updated my primary root. Being (apparently) brain-dead I blithely copied stuff over never realizing what I was doing. Fortunately, the only real repercussion was when things got pretty full and I realized what I had done I received numerous bruises from self-flagellation with a locally available and wielded clue-bat! :-( As to your current clean-up effort, I think Craig mentioned the rpm method.

I have to jump in here. A few months back, I tried replace some memory sticks with much larger ones. No go. But the specs said they should be compatible. After puttzing around with all sorts of things, I decided the only thing left was the voltage settings for the sticks. More memory has a greater draw. Not wanting to void the warranty, I didn't dink with it on my own. I carried the unit to my local dealer and said you do it if you think it is safe. Bumped the voltage a couple tenths and all worked. The reason is obvious. Why the "auto" setting didn't work, I can't say. Have been running successfully for many months now. So, if you've got the leeway, try manually bumping the voltage for the unit a couple of tenths. Risk is low, but it is there.

I'm a gambler, so I'll bet on this. Very large disks? If so, it may be that some of the tunables specify two blocks per "fragment" or the bytes-per-inode specifies more than 4K. I've been able, in the past, to affect things like this by tuning the number of i-nodes up/down when making the file system. Generally though, I'm reducing the number as there is a lot of space that can be gained since normally there will be 1 per block, IIRC. Since my desktop FS doesn't experience that much growth, and lots of the files are large, this is safe. YMMV. The output of the tune2fs command might give some hints. Also, using mke2fs with the "-n" parameter will tell you what it would do if you were to (re) make the file system. > HTH -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I second that. I had a SATA drive that showed a few bad sectors in 2008 sometime. I got the vendor software (DOS version) and ran the diags and repair. Used it for another year or so. Bad sectors started appearing again and I knew what this meant. Started taking more frequent backups. When it was convenient, downloaded the latest diags from the vendor, ran it repeatedly and every time it found and repaired more bad sectors and finally confirmed the drive was NG. Warranty exchange was easy and prompt. If you've been through a small initial set of bad sectors and are now seeing more (especially if you ran the vendor's software), the drive is living on borrowed time. This has been characteristic of drives for decades - a few early defects may appear, re-map and the drive works a very long time but when more start appearing a slow death is in progress. > > Mike ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

That's because fsck remaps /file system/ blocks to spares while the firmware/vendor diags handles media sectors. So if you fsck's inumerable times, the drive firmware is not affected and still sees the /original/ bad sectors until those are re-mapped. > HTH -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Usually within a containment vessel constructed of locally available raw materials, this reactor will be located somewhere near the center of the vessel. As native fauna approach it, they begin to experience uncertainty, apprehension and a strong fight-or-flight response. These responses are heightened as they observe that there are more than 3 operational control buttons on it, and even worse, that the universal controller often associated with it has a *zillion* control functions. These phenomena are most pronounced in fauna over 40 years of age, especially if the "User's Manual" has been perused. The purpose of the containment vessel is to reduce the chances of being carted off to an institution for rehabilitation by preventing the neighbors from seeing the cursing, screaming hurling of miscellaneous objects, falling on the floor and wailing and withdrawal into a semi- catatonic state that often results in the "user". The only known reliable preventative measure is for the fauna to procreate and wait until the offspring attain an age of 3 or so. At that time, all functional responsibility for the operation of the VCR is assigned to said offspring and the "adult" fauna are rendered irrelevant. -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The key is that one boot image can have different root file systems specified using the same kernel. So, configurations can be "pre-loaded" in each FS to look like the failed node. BTW, adding one more configuration that has the sole purpose of acquiring and applying changes to the other local images would be a good idea. It's only natural that over time some configuration changes will occur and one will forget or make an error when trying to replicate those changes to the spare. However, as mentioned by another poster, letting it set may lead to it being non-operational when needed. Cmos batteries expire, things age, dust collects, power surges get past various protections, etc. I did something similar to this back in 199(twoish?) with a network involved on a real UNIX 5.X system, that had NFS/RFS available, to protect my client in case of HD failure (the most likely scenario then IMO). All nodes ran continuously and user databases were distributed. Each node was sized to be able to hold both the OS and a copy of the largest 2 live data bases on any node (hoping that only one node would fail at once, but allowing for two). A cron entry did cross-copy of any changed components (excluding node-specific ones) during the wee hours of the morning and a small report was generated that let us be sure the "backups" had completed successfully. A tape backup of all that on the least loaded node was then done in background at low priority. It was not intended for the end-user to be able to automatically bring the "spare" into the mix as a replacement for a failed unit, but it was intended that I could quickly adjust it to do so. This would require only changing shared stuff (using RFS at the time) on the replacement and activating those shares. I think I also changed the node reference on the "clients", IIRC. Anyway, with RFS, that was quick and easy. I liked RFS a lot and was sorry to see it eventually go away. Sure enough, a drive failed eventually and I came away looking like a hero.

[CentOS] Can't connect to torrent tracker
Well, yesterday my 5.1 and 4.6 systems could connect to torrent.centos.org OK. Today neither system can connect. I can ping, but that's all. No changes were made to the firewall during this time.

Earlier, I tried using the rtorrent "enable_trackers=no" setting, but the man page says its useful for use with the scheduler. It had no effect on my attempts.

Going gangbusters ATM. Is it possible to have multiple trackers
available? If so, sounds like it would save some of us users work
occasionally. But I don't know if it adds substantially to the CentOS
team workload.

Still blissful (ignorance is ...), hit me with a clue bat if I'm way off base here. Now, that makes sense (IIUC the implications of all I've read and what y'all have posted). You had already been successfully connected and acquired the DHT during previous sessions. I can guess that this would be used in place of an (un?)available tracker. However, if one had not used a DHT-enabled client previously (my case), the CentOS torrent server was inoperative and the torrent file provided only specified one tracker URL, one should be SOL. After examining some other torrent files, it *seems* that multiple tracker URLs can be specified. Maybe this is all it takes to eliminate brief outages such as were recently experienced by non-DHT-enabled clients? This means that some community member would need to host a redundant tracker, torrents and images and the torrent file at the various trackers would have a complete list. Is it worth the effort? AFAICR, the recent outage was a wetware problem at a "critical" time and, ironically, caused by the bad judgment when the resulting workload was seen. I don't recall other instances of unavailability. Is 99.9(...9?) good enough?

All is working well and the rtorrent, delivering 4.6 stuff, and bittorrent (5.1 stuff) are playing nicely and sharing the bandwidth well. After seeding for an indeterminate time, I'll kill the GUI and start the console or ncurses bittorrent with the --trackerless option and see if it uses the DHT/routing and other information that bittorrent seems to stash in ~/.bittorrent/data directory.

AFAICT now, at lease an initial successful connection with a tracker, some time previously or currently, or multiple trackers specified in the torrent file is needed to initialize everything if the primary (only?) tracker is unavailable. So the "special" requirements seem to be at least one successful tracker-begun session by a DHT-enabled client or multiple trackers specified in the torrent file to allow "fail over" when the primary server is down and a DHT-enabled client is making its first attempt.

Through experimentation, I found it's even better than that: no trickery
needed!
With bittorrent, I simply positioned myself in the correct directory,
configured things, and fired up the torrents (genuine CentOS ones). Even
though the stuff was downloaded via conventional http methods, the
images and *sum files were seen by bittorrent, the checksums were run
and the images began immediately acting as seeds. Lots of peers came on
board and began downloading from these images. No downloads to me were
attempted. Last run of
strings ~/.bittorrent/data/routing_table | wc -l
shows 188 IP addresses. Some from the -curses and some from the GUI, I
suspect. I wonder if they are stepping on each other here? No matter for
now.
When I fired up the -curses version, I specified --
start_trackerless_client (IIRC, thats how it's spelled - bash_history
will remember for me) and it worked fine.
I just need to find a way to make sure that it can't find a conventional
tracker to see if that parameter has the desired effect. From what you
say, and what I think I've learned, should work OK. And may not even be
needed.
I note that there are 5.2.* and 6-beta versions of bittorrent available.
I though I might see if the prerequisites for them are on my 5.1 CentOS
(that my "experimental" node) and take my first shot at making an RPM to
contribute back to the community (rpmforge seems to be the appropriate
target).

My reading of the docs indicates that the hashed keys identify torrents and the keys define name spaces, which are further sub-divided and associated with nodes in the swarm to accomplish routing optimization. Connecting with any peer with any key should cause you to receive a new routing table, which I presume could (but may not need to) contain any/all keys (torrent info?) that any node in the swarm had seen. Since the hash algorithm that "defines" the CentOS images is well-known and common, that could provide an entry even when there was no tracker if the existing IP addresses (again, I assume they are retained) are polled and any of them are running a DHT-enabled client and you possess a torrent file with the appropriate key. Regardless of my meanderings, I'm comfortable now that "It Just Works". I just can't stand not knowing how once I get curious.

I doubt that will work. Most drives now (and SCSI even longer) have automatically remapped bad blocks so the fs manager never sees them. Utilities from the manufacturer are usually needed to do this.

See my reply, later today, to Re: [CentOS] Trackerless torrents (was: Can't connect to torrent tracker) Briefly, with the bittorrent from Rpmforge, which is old, a .torrent file that specifies a tracker cause the bittorrent to fail if the tracker can not be contacted.

Given: the bittorrent client available from rpmforge is old (5.2 stable are out there and 6.0-beta, but it seems both need porting to RH/CentOS before we can test/use them). I don't know if it is DHT-enabled. I've subscribed to the Rpmforge mailing list to see if there is a way I can help make the newer ones available. It'll be slow going because many of the prerequisites are not (transparently) met. It does look as if there are some alternative implementations of the needed GTK, wx, twisted, ... items. But I know nothing about them and can't tell if that is true. I think Dag and Co. will be able to point me in the right direction. Conclusion: current bittorrent from Rpmforge will not operate successfully on a tracked torrent without access to the tracker, AFAICT. Activity log attached. If others would like to emulate this test with other clients/OSs, I would find it interesting. > > AFAICT now, at lease an initial successful connection with a tracker, > some time previously or currently, or multiple trackers specified in the > torrent file is needed to initialize everything if the primary (only?) > tracker is unavailable. If one emulates the activities detailed in the log, with modifications toward testing if any of the clients connect when no record of a tracker ever being seen exists, I would find the results interesting. Further, one could also test when a tracker has previously been seen, but is currently unavailable. I would also find that of interest. > > So the "special" requirements seem to be at least one successful > tracker-begun session by a DHT-enabled client or multiple trackers > specified in the torrent file to allow "fail over" when the primary > server is down and a DHT-enabled client is making its first attempt.

And Over the decades I developed an excellent short-term memory.
... thinking ...
In the past I always made everything loadable modules because the target
hardware was constantly changing. So I always had something like this in
the modules.conf (at that time).
I really can't tell you how to find out. But in
/lib/modules/
there's a bunch of module* files. Man modules.dep and depmod is at least
a starting point.
Now, you mention a local repo. Does your /lib/modules have an entry for
the latest kernel? If not, maybe you just need a "depmod -a" run? If the
dates aren't already matching when you transitioned to 5.1, same?
My sata_via appears in modules.{alias|pcimap|dep} and shows a dependency
on it by sg_mod (a necessary module AFAIK). Since yours is usb based, I
would expect that a similar line ending with something that says either
usb* or *_

I'm almost certain that scsi_mod, sg and sd_mod are needed for all these scsi operations. The libata is needed by my sata_via driver, so may not be needed on your setup. > > > > It also has, in modprobe.conf alias scsi_hostadapter sata_via. The last > > is chipset-specific.

Then if one of them satisfies a dependency, or depends on another module that is loaded, the lsmod will show that. Once you have the modules.dep correct (depmod -a?) and have identified the chipset module needed (*if* any and it's not already loaded), you can try adding the "alias scsi_hostadapter ..." line specifying that chipset module. Then whenever the system tries to use something that requires scsi_hostadapter, the driver for that chipset will be automatically loaded. -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

So we can be certain that you need a scsi stack of loadable modules similar to the ones on my system that I showed earlier. On my 4.x, the only machine I have the flash drives in ATM), I see sd_mod 17345 4 usb_storage60937 2 scsi_mod 125901 2 sd_mod,usb_storage uhci_hcd 31705 0 ehci_hcd 31429 0 out of lsmod. I'm pretty sure you'll need those. But my usb is 2.0, so I'm not sure about the to *_hcd modules. I think those were common among the 1.x -> 2.x versions of usb. -- Bill ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
