Re: Certain distros not booting?
Do you think it could be drive specific? Either the drive or the media are out of spec? Can the drive really read the problem CDs? dd if=/dev/hdc of=/dev/null count=200 This should report an error if there is a problem reading the media. If this works, then the CD is getting read and I do not know what to suggest.

Certain distributions' install CDs won't boot. I can boot Ubuntu (both live and install CDs), I can boot Knoppix, but I cannot boot either Fedora Core 4 or CentOS 4.1.

Of course, I know what I'm doing and have invested in the time and tools to make Windows operate properly. But I've seen clueless Linux admins before, too.

Oh, really? When did that law get passed? :) I've had plenty of nix installations where the critical software most especially did *not* come from the distribution. But I think that is changing. My Fedora 3 system has about 20 manually installed packages. My Fedora 5 has 1. Most of that is due to greater package availability in the repositories. Even a limited sysadmin like me can look like a pro when yum install whatever-package-you-want does all of the heavy lifting and all that's left is to specify the config details that fit my operation. There should be relatively little rummaging around for installation media. The big time cost is not looking for CDs. You're probably better organized at keeping install media, updates, software unlock codes and the like in their proper places. I love that I can pretty much ignore all of that now.

I don't know of a way to generate a kickstart file from a working system. Maybe that's trivial, but a quick google only found push-style automation. That works so long as no packages are installed directly bypassing the kickstart data flow. The virtualization docs, if I am reading them correctly, seem to promise the ability to create system images based on the working install. That suggests automatically creating and saving snapshots for recovery purposes. That would allow for ad hoc package installs and updates while still having reliable system images for recovery.

Re: Dealing with multiple layers of routers
On Wed, 2006-06-07 at 12:09 -0400, Bill Freeman wrote: Where I'm working we have a Netgear router attached to the DSL modem, to which all the wired users are connected, with NAT and DHCP serving up 192.168.0.xxx addresses. One of the things wired to the Netgear is the internet port of a Linksys wireless-G router (probably too new to install Linux on it), which serves up a wireless network on 192.168.1.xxx. This works pretty well. Everyone can get to the internet. The local print server/disk server is on the wired network, so everyone can use it. Folks on the wired network can access services running on wired machines. But, of course, folks on the wired network can't access services on machines connected to the Linksys (even using a wired connection to it). The trouble is that we would like to offer the latest development version of our web app running on our wireless development machines to the marketing folks on the wired network. Sure, it's easy to configure a particular port accessed at the internet port of the Linksys to go to a specific machine on the wireless network, but we would like to have multiple marketing folks able to access multiple developer's machine's servers. And we don't want to re-configure the router everytime we want to change who serves what. And spur of the moment instigation of an ssh session from a marketing machine to a specific developer machine is desired. I think that what I need to do is disable NAT and firewall on the Linksys. (We would still be protected from the internet by the firewall in the Netgear.) If that's possible. Sounds good to me. Then would I be able to configure the Netgear's DHCP server to tell the wired folks to route to 192.168.1 via the IP that the Linksys has on the 192.168.0 network? Or woould it be possible to hide the static route from 192.168.0 to 192.168.1 entirely in the Netgear's internal routing rules? I would expect this to work. The netgear router is the default for everyone in 192.168.0.0/24. The netgear knows to reach 192.168.1.0/24 via 192.168.0.xxx - the linksys ip address on the 192.168.0.0 sub net from the internal entry. I lent out my linksys router, so I can not test this - I do not have a production system at risk here so I could test with impunity. Presumably you are controlling the DHCP assignments so that your Name Server knows how to resolve names to numbers and DNS is not tied into those routers. (The wireless folks already go to the Linksys for routing to 192.168.0, since it's not within their local network's netmask.) Or am I likely to have to hand configure all the wired guys with a static route to 192.168.1? Or I guess I might be able to connect the routers via downstream ports on both, using a cross over cable. Then I either need to disable DHCP on the Linksys (that I'm sure that I can do), or arrange for both DHCP servers to specify a 255.255.254.0 netmask, and the Netgear as the router to the internet. (I'd actually like to keep the wireless guys with 192.168.1 addresses and the wired guys with 192.168.0 addesses, but this is a much softer requirement.) I'd appreciate comments and (some of the) suggestions.

Re: LinkSys WRT54G and OpenWRT
still being accessible to newbies (and I'm still a newbie to OpenWRT). There are many options, but they are divided into categories and subcategories that made immediate sense to me. There are links for More information all over the place. When a function needs some optional packages to make it work, there were widgets right there in the UI to click to install them. I installed and configured NTP easily in this way. The only issue I faced with installing packages was that the ebtables modules were not automatically loaded (insmod) with the kernel. The fancier package managers always took care of this for me. I solved this by grepping through the the startup scripts looking for where the iptables modules got loaded (/etc/modules.d/40-ipt-nat-extra) and then added the ebtables modules to the list. Conclusion -- That's about as far as I've gotten so far. There's a lot for me to learn, but the docs on the OpenWRT site seem to have lots of info to at least get me started. The documentation is very helpful, and quite detailed. Also notice that the (my) list of nvram variables is only 537 lines. Most of configuration choices boil down to setting a small number of variables to a consistent set of values. This can get mapped into a GUI interface pretty effectively. All in all, given that this involved replacing the entire OS of an embedded device with third-party software designed by and for Linux geeks, this was about as easy and accessible a project as I can imagine. No configuring a kernel, no opening the case and installing extra connectors, no cross-compiling. It was point-and-click.

I don't really understand this point. Aren't DSN concerns essentially the same between the alias host and the mailbox host? A lot of mail servers reject spam during the SMTP transaction. If there is no forwarding involved, the spam cannons just bounce off the mail server. (Legitimate failures generate a DSN at the originating system, which also works fine.) But add in an alias/forwarding system. Now the alias host accepts the spam, and tries to forward it on to the forwarding target. The target MX rejects during the SMTP transaction from the forwarder. Since the forwarder is not the originator, it has to generate a DSN, and then attempt to deliver said DSN to the originating system, based on the information from the SMTP envelope. OK. I see what you're saying. I assume my server tolerance for bad email matches reasonably well to the final server (Maybe it's fussier). If it was good enough for my server, it will also be acceptable to the mailbox server. I am not generating many DSNs. Since that information is almost always forged, the alias host ends up trying to deliver tons of DSNs to all sorts of bogus addresses -- some of which match to real people, who then email the postmaster of the alias host and ask them to stop emitting backscatter. (Or, more likely, threaten bodily harm and/or legal action.) Did that make sense, or just confuse the issue further? :) Thanks for taking the trouble to explain. One other item I've noticed. More and more mail servers are not bothering to report delivery failures. I get complaints about undelivered emails and I respond with log entries showing that their ISP accepted the email for delivery.

The wires would then be suitable for DSL. However, you are a long way from the Lebanon Central Office (603-448- looks like Lebanon based service). The only way they could make DSL work would be to provision it from a SLC. I am not sure they are willing to do that. Possibly the gear Verizon has been using in SLC's doesn't support DSL.

This implies that DSL actually means something specific. It generally doesn't. There are a bunch of flavors of DSL, and they don't all work the same way. Further, there is often disagreement over what the flavors are, so terms are not always equivalent across markets. (It's similar to how terms like SCSI-3 gets applied to connectors, cables, speeds, and other things, with no consistency, because SCSI-3 is just a standards document that covers all of that. The terminology gets abused.) I was informed that Verizon has been using two-pair HDSL when possible. This provides approximately 750 Kb per pair. I can confirm that they run two pairs from the punch block to the line card. I have no obvious way to verify that it is truly HDSL on the wires. Google found these (DS1 HDSL) http://www.jdsu.com/france/technical_resources/product_documents/outline/TT-DS1-HDSL-WS.pdf http://honolulu.hawaii.edu/cet/courses/courses_tele_fiber.htm Also you are quite right about the utter semantic mess that DSL acronyms represent. That's why I simply said DSL (Digital Subscriber Line) which is pretty generic. There are some flavors of DSL that re-use older equipment in new ways. In particular, the line cards for both ISDN and T1. Line cards just transmit bits; they don't really interpret much. So there are DSL flavors which use ISDN or T1 line cards. The defunct Vitts called these SDSL (symmetric DSL) and HDSL (high-speed DSL), respectively. I don't know if Verizon even offers these services. I know that most asymmetric DSL being delivered by Verizon in this area is a 1-pair (2-wire) system, while a T1 is a 2-pair (4-wire) system, so the Verizon ADSL I've seen is not the same thing as a T1.

If they're being provisioned on DSL lines these days, I wonder if I could order a T1, have them fix the induction coil problems on our backhaul to get it out here, then cancel the T1. There are multiple factors in play. DSL is usually offered as a low-price, consumer product, while DS1s are usually higher price, business class products. Businesses are willing to pay a lot more, so the telcos are willing to do a lot more. When line quality is bad, T1 installation will often involve running a brand new copper pair (or reconditioning existing pairs) the entire distance from the CO to the demarc. This is typically billed per foot and can run into the five figures if you're sufficiently far out in the woods. T1 also allows for extenders (in-line amplifiers). If they reach the distance limit, they install an extender on the pole. They'll run a separate power pair if needed. This is also expensive, and -- more significantly -- just not done for consumer DSL. So even assuming you didn't get hit with an early cancellation fee, you'd likely end up with a line that was still not useful for DSL, due to the distance limits mentioned above. There's also the fact that the telco could probably just say, That's a T1 line, not a DSL pair. Even if we *could* run DSL over it, we're not going to. It was installed for a T1, and we're not going to let it be used for anything else but. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/ -- Lloyd Kvam Venix Corp. 1 Court Street, Suite 378 Lebanon, NH 03766-1358 voice: 603-653-8139 fax:320-210-3409 ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
fair pricing of bandwidth
My office is in a building where several businesses share an Internet connection and simply split the expense. There are no bandwidth/packet shaping controls. I expect we will upgrade to a 10 mega-bit connection with a lower-committed level of service (possibly 3 mb?). I'll install bandwidth monitoring and control. Each user will get a minimum / maximum bandwidth allocation. (Finally the question) Do any of you know of a fair algorithm for allocating costs with this kind of model? My inclination is to simply allocate the cost based on the share of the minimum service levels. min0 / (min0 + ... + minN) = share of connection cost for user 0 That's easy to describe and hopefully fair enough, but I'd welcome suggestions for a better approach or a pointer to any papers on the subject. I suspect that a fair system is not linear and that the cost of doubling the minimum bandwidth should be less than double the original cost. -- Lloyd Kvam Venix Corp ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

fedora 7 on laptop no longer burns CDs or DVDs
I recently upgraded my laptop from fedora 6 to fedora 7. Now I've discovered I can no longer burn CDs or DVDs. I have an old CD-R burner, so this is not critical yet, but I will need to get this figured out. The drive is identified below in the wodim output, but is a fairly typical IDE combo drive. As I recall, it was /dev/hdb with fedora 6. Now with fedora 7 the drives get scsi style names. Besides the output from wodim (a typical run is pasted below) there are also syslog messages like: Sep 11 00:09:35 laptop kernel: cdrom: This disc doesn't have any tracks I recognize! which seems like a media problem, but happens for all of the media that I've tried. My assumption is that the laptop cut some corner with the drive setup so that there are errors which got ignored or went undetected in fedora 6. Booting the fedora live CD into RAM made no difference so it should not be some peculiarity of my software configuration. Booting from Knoppix ties up the drive so that I can't burn. I'll be trying to boot from USB with an alternative distro (Knoppix? PuppyOS?) to prove the hardware works, but thought it would be worth soliciting advice. (Google has not helped as entirely too many people have burn problems.)

So if they happen to be polling the device when wodim tries to open it, you get the warning. Then they close the present poll, and wodim retries, and it works. Then, during the middle of the write, they poll again, and kablooie. At least, that's my theory. Well I shutdown to single user mode. wodim chugs along until it thinks it has written 26 MB and then decides that things are not working. The CD media still appears to be blank.

So why/how does cat become a verb meaning send file to another program? Is it because cat is often used to dump a program to the terminal? This discussion has really succeeded in drumming into my head that input output filter args are commutative. You can shuffle them into any order and the line works. (A program like cp gums things up because it is not a filter.) input does nothing by itself. It needs cat or some other process to use the redirection.

Feed the output from sqldump into your backup. mysqldump will flush and lock each database as the database is backed up, but does not, by default, protect consistency between databases. If that's a concern, an LVM snapshot (or equivalent) might be better. The output from sqldump is a file of SQL commands to recreate the database(s).

ttyUSB monitoring
I bought a GPS tracker (RGM-3800) under the delusion that I would be able to collect data from it using Linux. Unfortunately, it is using a proprietary protocol to collect data. The serial connection is 115200-n-8-1, but the device does not use the normal command sequences. The Windows software will sometimes work using WINE. I expect that I could reverse engineer the key features if I could monitor the ttyUSB device data stream. So far I've been unable to google anything useful about enabling a serial device monitor (tcpdump for the serial device) that showed the data stream. statserial will show the status pins. I would think that usbserial (pl2303.ko) would have needed a monitor mode when it was developed simply because it is such a synthetic device. I'm hoping someone here can kick me in the right direction. (The tracker connects using a USB cable so I can't use a serial breakout box or any hardware based serial debugging facility.)

Yes, it can charge and act as a GPS, no it can't transmit any data over USB. Unfortunately the bt-5 still appears to need a separate device to actually record the data. I was looking for a simple standalone device that would record positions for later processing. The rgm-3800 is small and light and looked to be ideal for creating logs while bicycling, hiking, or cross country skiing. I've been using it with gpsdrive (and gpsd) for a while. Works really nicely and is a great price for anyone that wants to experiment with either GPS or bluetooth devices. -Mark If the pointers I've gotten from others fail to do the trick, I will need to look at switching to a different device.

Have daily tapes for Mon, Tue, Wed, and Thr. Have weekly tapes for Week2, Week3, Week4, Week5, that get used on Fridays. Have monthly tapes (Jan, Feb, ..., Dec) that get used on the first Friday of each month. This gives you automatic adaptive granularity -- more backups of more recent changes, fewer of older data. This tends to fit well with most data loss scenarios. An alternative to tiering the tapes, is to tier data to disk. The packages rdiff-backup and dirvish provide for date-layered backups on disk. dirvish uses hardlinks to avoid multiple copies. rdiff saves deltas to regenerate files to a point in time. Lost files are easily restored from rdiff or dirvish. Then amanda can be used to write tapes for off site storage. Getting amanda to tier your tapes is probably not worth the effort. Use backup disks rather than tapes if you prefer. -- Lloyd Kvam Venix Corp DLSLUG/GNHLUG library http://www.librarything.com/catalog/dlslug http://www.librarything.com/profile/dlslug http://www.librarything.com/rsshtml/recent/dlslug ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I talked about a gotcha where I tried to define __iter__ as a classmethod. When using SQLAlchemy it is often handy to define classmethods which will act as constructors for the object instances that reflect the database records. These constructors often return iterable query results. I was planning to have __iter__ run a query that would iterate through all of the records. Unfortunately for record in Myclass: print record.name ... does not work. python will try to find an __iter__ method in the parent metaclass and fail. Implicit references to magic methodnames (__xxx__) that *are classmethods* resolve to the parent metaclass. Kent pointed out that for record in Myclass.__iter__(): will work and also provided a simple metaclass workaround. On reflection, I think that the notion of making __iter__ a classmethod is a mistake. It preempts the possibility of an iterator for an instance. Providing a name (i.e. all) and coding for record in Myclass.all(): makes more sense.

Off-topic - Mounting multiple USB sticks on Win XP
A neighbor asked for help with mounting his USB sticks. He has directories mapped to drive letters D,E, and F to mimic partitions from the days when Windows could not handle large partitions gracefully. When a USB stick got inserted, it grabbed the D drive letter fouling up his software. I helped him find Control Panel/Admin Tools/Manage Computer/Storage/Drives and changed the USB drive to U. This seemed to work OK. It also appears to mark the drive letter on the device rather than configuring the system to start lettering from U. However, it turns out he has two USB sticks he uses for backup and data transport. He mapped the second one to V. When both USB sticks are mounted at the same time, only one stick gets a drive letter. The other stick is unlettered and unavailable unless he goes through the control panel to manually assign a drive letter. Is this normal Windows behavior? Is there a simple way to force drive letter assignments on USB sticks? Can you mount two at once? (My winNT box does not support USB so I can't do much research myself.)

I rely on replication mostly for off-site backup, but I've read of people splitting databases as you have done for performance reasons. I imagine a workable solution could be made, but I've only setup replication between multiple boxes, not multiple databases on the same box. I'm not even sure that's a supported configuration for replication - not sure how you'd do it. I've done it by specifying host and port for the master. And any real-time replication would probably face the same locking problems. If you just restricted replication to play catchup at regular intervals and then you'd still want to disable the Bayesian filtering at those times before doing the replication, because it would hang up matters. The replication stream is handled at a low priority, but I am not going to argue against your decision. One problem I did run into was that the binlogs filled up fast. After only a few hours of a full load of traffic, the binary logs had filled up several gigabytes of space. The MySQL traffic is an overwhelmming percentage of INSERT statements: http://jenandneil.com/sites/jenandneil.com/files/sf00.dc0.oasis-open.net-mysql_queries-week.png In my original partitioning, this was especially a problem since those, the databases themselves, the logs, the Exim queueing and spooling and tmp space, etc were all on one partition for /var. I've broken it up some to get some isolation, but it's still just one physical disk. The IO of keeping up a binlog with everything else happening would result it more IO overhead than I want to spend on replication. OK. Thanks very much for taking the time to explain. That is very convincing and enlightening. The IO is even worse than you outlined: binlog, relaylog, replicated table. I would venture that the computing effort required to replicate all the queries that happen in a few hours time would be far more costly than the couple-of-minutes spent re-duplicating the database. -N -- Lloyd Kvam Venix Corp DLSLUG/GNHLUG library http://www.librarything.com/catalog/dlslug http://www.librarything.com/profile/dlslug http://www.librarything.com/rsshtml/recent/dlslug ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
