[vox-tech] port forwarding
I have been looking through the logs and set-up of my router. I found that a port is being forwarded to one of my wife's laptops. Since port triggering is disabled, how is this possible? Is there a normal function for this or does this mean the router has been comprised? The port is 59215, UDP. I searched but haven't found any clue as to its use. The laptop in question is a Dell and fortunately does not have any important data.

Re: [vox-tech] Email
Thanks for all the suggestions. I wasn't able to get the import function in thunderbird to work. What I finally did is: open thunderbird and create the folders (empty, of course) Then I exited thunderbird and, one folder at a time, I deleted the folder (directory) and then re-created it using a python program that converted a maildir to mbox. Next time I opened thunderbird my emails were there.

The local IMAPd is said to have _its_ message store in Maildir. Answer #1 was: Use a local mail reader to bulk-pull all mail from the local IMAPd and save the mail from the local mail reader, e.g., to mbox format. Then use that mbox with Thunderbird. (The helper was a bit vague about how to do the latter part.) Or, helper #1 adds, move the entire Maildir tree to the machine where Thunderbird will be running, install Dovecot as a local IMAPd on said machine with the Maildir tree as _its_ message store, and configure Thunderbird to take its mail from the local IMAPd. Answer 1a was a bit baroque, but suited the situation where the user had a local IMAPd. But Richard doesn't have one of those. Answer 1b is even a bit more baroque, but in present context not only assumes Richard has a local IMAPd but also will want to keep using one. Answer #2 was: Install the Import Export Tool extension for Thunderbird (that I've mentioned before). Rename all individual mails in the Maildir trees to have .eml filename extensions (using utility mmv) and then use the Import Export Tool extension's feature to 'Import all EML files from a directory'. This would work, if Richard has the mmv utility. I admire answer #2; it's ingenious. Lots of ways to solve the problem, and this one exhibited lateral thinking. My own inclination would be to attack the problem directly and convert the Maildir tree to mbox using a utiltiy for that purpose. ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

I believe you mistyped 'Ah, thank you for calling attention to my omitting any coherent details of what format my old email is currently in. It's trapped inside whatever datastore KMail [you supply version] uses.' (Hint, hint.) One issue is that KMail used a number of storage formats over time, sometimes offering a couple as options. Here is an article that describes a user of KMail 2.x (from KDE 4.7.2) getting out of KMail to Thunderbird with his mail intact: http://www.ulduzsoft.com/2012/01/from-kmail-to-thunderbird/ (Author 'George' doesn't like the default mbox format used by Thunderbird, so configures Thunderbird to use Maildir instead.) One obvious workaround irrespective of KMail's storage format -- usable _if_ KMail is working well enough to sync to remote mail servers -- would be to sync KMail's local folders to a remote IMAP server, and then IMAP-sync that same mail downwards (the other direction) into Thunderbird. For extra credit and vastly greater speed, do this via an IMAP daemon (such as Dovecot) and MTA (such as Exim/Postfix) that you run locally on you Linux host. But that might be more setup than you care to take on. Tip: On general grounds, you'll want this extension for Thunderbird: https://addons.mozilla.org/en-US/thunderbird/addon/importexporttools/ It makes bulk-importing of mbox-formatted mail files more human-friendly than without the extension. The extension does not, however, natively understand any other file formats (e.g., Maildir). ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

Re: [vox-tech] C++ problem
Thanks for the suggestion. With valgrind I found all the problems. That the variable was local to the constructor was not a problem. The main problem was that I was later assigning another value, over-writing the value from new. And of course that meant the delete couldn't work either. I have a larger program that does extensive new's and deletes and I have had it run for hours without running out of memory. I wrote that several years ago and I guess I've gotten rusty.

I thought an Asus N82JQ looked good -- i7 processor with Nvidia 335M graphics but then its battery life is not too good. Can anybody suggest something with good processing power, Nvidia graphics and not too terrible battery life? Also, I don't want too large, 14 screen looks to be good. I will be installing linux, of course. Richard Harke ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech
Re: [vox-tech] failed to build a computer
Most of the systems I have built used beep codes for he most serious failures. This required a small speaker (usually comes with case) and connection from mobo. Manual should tell you what beep codes mean.

If I pressed the cle cmos button (there is one on the ft02B case, so I guess I don't have to jump) during this process, the reseting stops, but still no video signals. Next time I power up, the above happens again. both atx_12v_2x and atx slots were hooked up with the PSU; two rams were on bank 1 2; power/reset sw and others were rightly put in the F_PANEL. two PCI-E cables from PSU were hooked up with the video card to feed power.

[vox-tech] (O.T.) Strange Image
I was perusing satellite images on google maps when I happened across Hell Hole Resevoir. There was a very strange image on or over the water that i could not identify. I'm pretty sure the satellite doesn't get bugs crawling across the camera lens so I'm puzzled as to what this thing is. If any one is curious, maybe they could look at it and maybe some one can identify what it is. (Hell Hole Resevoir is in the Sierras, east of Georgetown and west of Lake Tahoe.

Re: [vox-tech] Acer AL2216W (blank screen)
In recent years I have noticed that video cards die distressingly soon. Often with strange symptoms that make it appear to be something more basic. I do have to admit that the most recen time (about two weeks ago) it was in fact the monitor. That was an HP 22 LCD monitor only 5 years old. My previous monitor was a Sony CRT that went back to the early 90's. I can only suugest that you try swapping out starting with whatever you can do cheaply. Especially if you can borrow a component for testing. I do have an extra video card but I'm not in Davis so you'd have to wait till the regular Lugod meeting.

Everything was working great until last Monday morning. I powered up the computer, activated the external monitor and the max resolution was 1280x1024 (the native resolution is 1680x1050 - same as my laptop display). I didn't do anything to modify any video settings so I don't know exactly what prompted the change; however, there were about 10 bug fixes the day before. Looking at the history of fixes I don't see anything that looks likely to cause a problem, but I am certainly not a Linux expert. Anyway, I have spent the last 4 days doing everything I can to make it work again: updated drivers, uninstalled/reinstalled drivers, deleting the xorg.conf file and having one auto generated, manually editing the xorg.conf nothing has worked. In fact, the situation is now worse. I can't even get the monitor to display anything anymore - just a black screen. I think the monitor itself is fine, if I turn it on I see the ACER logo appear, then I briefly see a dialog box that says no signal, and then it goes blank. I don't have a great understanding of the xorg.conf file, but I was very careful when editing it. I read all of the NVIDIA documentation online and I found examples of xorg.conf files online from people with this same monitor who claimed to have it working, so I don't think I used a refresh/sync rate beyond what the monitor is capable of (I didn't smell any smoke!). My Google searches have indicated that many people have had problems reading EDID data from this monitor. I have even plugged it into a Windows machine with an ATI graphics card and same thing...blank screen. I checked the /var/log/Xorg.0.log file and I see this warning: (WW) Sep 16 15:07:43 NVIDIA(GPU-0): Unable to read EDID for display device CRT-0 there are no errors (EE) generated.

Re: [vox-tech] Fwd: Very slow off net
For example, the solitaire card game. Bu it appears to happen with all applications. I don't believe it is coming from the application but somewhere in the system code that launches the app. I used wireshark. let wireshark run. no traffic. Launch an app. As soon as it is up, check wireshark. There are several packets shone, including the DNS queries. Also, it appears no use is made of the DNS queries in that I do not see follow up traffic. Since it is not a particular application I don't know how I would use strace. I did forget to mention one important difference between my laptop and desktop. The laptop is running gnome while my desktop is running KDE. When I thought about this I began to think maybe gnome is responsible but I don't know how to check this.

You say I've done some tracing, but I don't know what you've done to associate DNS lookups with particular non-network-oriented applicaitons. Once you know what application binary you're talking about, you can run it under strace to determine what system calls it's making. By the way, IMO, you really should consider running and using a local recursive DNS nameserver. Doing so improve performance a great deal over using your router on your home network, which almost certainly is merely a forwarder. It'll also improve performance over using OpenDNS, along with not giving the operators of that service detailed information about your Internet activity, _and_ (unlike OpenDNS) it would actually implement DNS technical standards correctly (i.e., correctly answering NXDOMAIN when that's the truth).

The file is dated 10/20 so it might be from when I used the wifi at Borders. I had to change my interfaces file and do a ifup ath0=borders to get connected. Could that have given permission to rewrite /etc/resolv.conf? I guess I could check this out the next time I'm at Borders. I used wireshark to trace the net happenings. I just retried with the net connected to see if there was any follow up to the DNS query. For firfox, er iceweasel, there was but for a card game no follow up.

Re: [vox-tech] Buying an LCD screen
I bought an LCD monitor a couple of months ago, an HP w2207. If I remember right it was around $350. at Frys. I have been very happy with it. But I don't remember the contrast that they claimed. I went back to the spec sheet and I can't even find it mentioned. My memory is fuzzy but i think it was 1000. I believe the contrast for CRT's is normally taken to be around 500 so that might serve as a minimum for pure text work. I also under stand the contrast number tends not to be very precise and subject to a lot of hype. But be sure to check out the sharpness. When I was in the store it seemed like several monitors were showing text rather poorly. The salesman claimed it was because they had several running in parallel on a common feed but salesmen have been known to fudge. I am very happy with the sharpness of this monitor as most of my usage is text. Richard On Wed July 25 2007 10:23, Ken Bloom wrote: I'm looking at buying a new LCD monitor for my compuer.

The scripts themselves typically live in /etc/init.d For example, if there is a link in rc2.d named S99xdm - ../init.d/xdm, the script xdm will be called with the command to start -- because of the S as the first letter of the name. the 99 means this script will be among the last to be called for the run level. If the name of the link is changed to K01xdm - ../init.d/xdm, the the script is called with stop as the command. So I change the name of the link in /etc/rc2.d and change the default run level to 2 I can then login as myself and do startx or login as root and do init 3 which forces a change to run level 3 which will bring up X in the same manner as if booting into it. Be sure to check for scripts not only for xdm but also for kdm and gdm Richard harke On Mon March 26 2007 22:06, Gandalf Parker wrote: On Mon, 26 Mar 2007, Nick Schmalenberger wrote: In my experience the neatest way to stop a Debian machine from starting X on boot is to remove the package of the display manager.

That is what would happen if you remove the package, except it is still there and you could still do /etc/init.d/xdm start if you felt like it. OK I tried that: /etc/init.d/xdm start Not starting X display manager (xdm); it is not the default display manager When you do startx or log in through the display manager, it should try to start your window manager, and (I think, correct me if I am wrong) if you don't have one it gives you a fixed size xterm, which you can really do a decent amount with. I did manage to get that on one of the things I tried. But running the command I wanted within that window just seemed to give me the text mode results instead of the gui version. I seem to remember having problems a few times getting icewm to start when I start X and I think adding it to .xinitrc was one way to get it to work. The correct debian might have something to do with /etc/alternatives. Im giving up for tonite. Maybe in the morning I will google a few of these things and get some more items to try.

Re: [vox-tech] [OT] Numerical algorithms in C
A resource I would also suggest is a book titled A Numerical Library in C for Scientists and Engineers By H. T. Lau. This is from CRC Press. I got a copy several years ago so I don't know if this is still inprint. It came with a floppy so there was machine readable source code. A large part of the book deals with linear algebra and many specialized forms of matrices. (I was able to use some code from this book to solve 4000x4000 matrices with 31 non-zero diagonals. This solver was the inner loop in solving some differential equations) The book itself prvides detailed documentation, no small thing in this kind of work. And especially when you wish to make modifications. Richard Harke On Fri February 2 2007 00:01, Peter Jay Salzman wrote: Is there something equivalent to LAPACK or NAG in C?

[vox-tech] For C gurus
I have seen something like the following to describe how setjmp/longjmp is used, though asub is likely to represent a complicated tree of calls with a variety of potential failure points, with longjmp being the quick and easy way out. int asub(jmp_buf env) { .do something longjmp(env, 1); } int main() { jmp_buf env; /*init*/ some code if (setjmp(env);) { /* returned from longjmp */ clean up exit(0); } else { /*just returned from setjmp */ asub(env); may not return } } But suppose this is changed to the following: int asub(jmp_buf env) { .do something longjmp(env, 1); } int my_wrapper(jmp_buf env) { int x; if (x = setjmp(env)) { return x; } else { return 0; } int main() { jmp_buf env; /*init*/ some code if (my_wrapper(env);) { /* returned from longjmp */ clean up exit(0); } else { /*just returned from setjmp */ asub(env); may not return } } Notice that because we returned from my_wrapper before calling asub, the local variables for asub have been removed from the stack. Thus they cannot be restored by the longjmp. It seems to me this usage should be explicitly rejected. Can any one point me to an authoratative reference that says this?

Re: [vox-tech] aptitude problems after a couple dist-upgrades
You probably have a mismatch between distribution versions. There are two ways to name debian releases and they move with respect to each other whenever a new version is released. i.e., at some point sarge was testing and later it became stable But the install likely set up your sources.list to point at unstable rather than explicitly pointing to sarge. So when you did a apt-get dist-upgrade, you were actually trying to jump a whole release. This has been known to create the crap you are seeing. I'm not sure how to fix this except to start over and before you do the dist-upgrade, be sure your sources.list is pointing explicitly to sarge. Once you have the latest sarge, you can change your sources.list and move to etch, if you want to. You could of course just stay with sarge.

Re: [vox-tech] grub booting
I assume that you ran grub as part of the pephis install. First, I would note that it should be possible to mount the debian partition(s) under mephis. This would allow you to copy over or make back-ups (What a thought!) If debian was installed on a single partition then when you mount it, you can see all the root stuff, like /usr/bin and /lib but of course you will still be running the versions from mephis. As far as booting -- you need to look at the file /boot/grub/menu.lst You will need to modify this file to add a stanza for debian. This will be a bit tricky as you can learn the form of the stanza by the one for mephis but you will need the exact values to insert. One way is to look at the menu.lst for debian. This should be at /mnt/boot/grub/menu.lst if you mounted the debian partition at /mnt Make a backup first as this is easy to screw up.

However, in that case you need DIFFERENT network numbers on the upstream side (your LAN) and the downstream side (your Wireless network). The fact that one laptop works would suggest that you have worked this out, but in previous posts you have mentioned using 192.168.1.x for your wired LAN so it seems worth bringing up. Also, I try to use DHCP and config the WAP to assign specific IP addresses by MAC address if I want static setup... this is much more flexible for the laptop configuration. a) wired network config? b) WAP is firewalled or bridging? c) what commands did you use to test connectivity, on what computer were they invoked, and what were the results? My laptop is configged to use a wired connection also. I have a jack in the dining area in case I work on the dining room table. But I found I had to do a ifdown eth0 (the wired connection) before eth1 would work. eth0 is auto but eth1 is not. I also want to use the wireless at hotspots and that turned out to be quite a hassle. I have a mapping stanza in the interfaces file and that took a while to get working. What works is LOGICAL=HOME ifup eth1 The environment var LOGICAL is then used in my script that is called from mapping stanza. There is another name for a hotspot config. One issue remains. If I go out to a hotspot, when I come home it does not work cleanly. I have to manually modify resolvconf as it continues to have the hotspot DNS enteries.

Most machines conform to this standard, although some languages (C, C++) do not guarantee that this is the case. It's a poorly written paragraph, but seems to say that C and C++ don't guarantee adherence to the IEEE 754 standard. If this really is the case, why don't they? I suppose if your hardware supports something else instead of IEEE-754, then a conforming C/C++ implementation can use the hardware, rather than having to emulate IEEE-754. In fact, IIRC, C predates IEEE('s very existance as an orginazation) by IEEE is actually quite an old organization around 100 yrs, I believe. IEEE has sections for power generation and transmission, and many others, not just computers. quite a bit. But the best format for every machine isn't IEEE-754, IBM and Cray have used their own formats for floating point (though, AIUI, for the most part they have supported IEEE-754 in addition to their own). Note that C doesn't even have particular requirements on the radix used by the floating point model (i.e., it doesn't have to be 2. Hell, it could be 10!). However, you can test for the existence of a macro, __STDC_IEC_559__, whose existence guarantees conformity to IEC 60559:1989 floating point (which is the current designation for ANSI/IEEE 754-1989, which was also designated IEC 559:1989 before it went to 60559. If that macro is defined, then you are free to assume the usual semantics for floating point. C++ uses a completely different approach . You use the numeric_limits type defined in the limits header: if (std::numeric_limitsdouble::is_iec559) { ... } AFAICT, the __STDC_IEC_559__ macro is only available in C99; my draft copy of C90 doesn't mention it (but does refer to IEEE 754 in some examples). However, float.h provides a number of definitions useful in describing the floating-point model used, and there are certain guarantees made about them (such as a double being convertable to 10 decimal digits and back without loss of information). For a long time, there has been no way in C to control floating pt modes but I think recently some effort has been made. Rounding modes in particular can be quite important in some computations. I think C mostly goes with what is expedient with the hardware in use. On x86, the hardware float registers are actually 82 bits. This can be accessed directly with some compilers as long double But, OTOH, if you specify double it will be expaned to long double when loaded into a register. Now if it stays in the register through a series of operations, the result can subtly different than if it was rounded to double after every intermediate operation.

Re: [vox-tech] Etch sources.list
I think the point is that no matter which level you run, you do need to be aware of what version you are actually running. I had my system pointed at testing for some time. Then it became stable. And testing, which had been sarge was now etch. I started having strange failures when I tried to update my software. The solution was to set my sources.list to sarge, do a full upgrade to make sure I had the released version of sarge, then change to etch and do another upgrade. The way Debian is suggesting means that when they make the switch you won't have any weirdness although you'll be down revision from where you want to be ( something easily fixed) Either way, you need to be aware of when a new stable is released.

King [EMAIL PROTECTED] said: Not sure if I'm understanding your question aright, Peter, but I think you're asking if the equivalence relation (1) is isomorphic to the equivalence relation (2). That is not the case. If you view a matrix as defining a parallelopiped in n-space, then the determinant measures the volume thereof. Now it is easy to have two parallelopipeds which are not congruent but which have the same volume. The relation (2) defines a set of equivalence classes which is much finer than the set defined by (1). To put it another way, the determinant is only one of many matrix invariants. The full set of invariants under the relation (2) can be summarized in the Jordan form of the matrix. Apologies for pontificating, especially if I've answered a question you never asked. Cheers (and congrats on the Ph.D.!), Aaron Don't apologize -- this is exactly what I wanted to know! OK, so then it's not true that all matrices with the same determinant are related by a rotation. I was going to ask about trace too, Tr[M_b] = Tr[S^{-1} M_a S ] = Tr[S] Tr[M_a^{-1}] Tr[S^{-1}] = Tr[M_a^{-1}] != Tr[M_a] but trace isn't invariant under inverse, so the trace relation can't be equivalent to relation (2) either. Thanks for chiming in! Pete You might want to look at how Clifford algebras express linear algebra. Normally one works with frame free expressions where invariance under change of basis is inherent. Both the trace and determinat are easily expressed this way. Also, one see that there are additional invariants for a total of n in n dimensional space. Also, eigen values are handled in a more natural way. One can have, for example, an eigenbivector which expresses the invariance of a plane while vectors within the plane are not eigenvectors. For a rotation in three space the axis is invariant but also the plane of the rotation is invariant even though no vector in the plane is. I reccomend Geometric Algebra for Physicists by Chris Doran and Anthony Lasenby (Cambridge) As the book is fairly expensive I also mention the web site http://www.mrao.cam.ac.uk/~clifford There are a large number of papers posted there for free download.

[vox-tech] Laptop woes
I have an HP Omnibook 6000 with Debian installed. This was installed from unstable about two years ago so I believe coresponds to sarge. For a long time I just used it for email and left it on power and running. Then I shut down about 3 months ago and now I'm trying to use it again. The problem is that I can't login. No, I didn't forget my password; it doesn't let me enter the password. After I type my login name and press enter, there is a pause and then it shows Login incorrect It then repeats the Login incorrect 4 more times (with pauses) and then says too many tries and goes back to the initial login prompt. If I boot in safe mode (single) I can login as root by just entering the password and then everything seems to be OK. I did a shutdown and re-boot and then had a very large number of problems out of fsck, although the disk was fsck'ed just a few minutes earlier. After doing root in maintenance mode and cleaning up the reputed disk problems, a re-boot led back to the same login problem. Has anyone seen anything like this?

The second line tells GRUB (but not the kernel) where it can find the partition with your kernel on it. If you don't have a separate /boot partition, then your configuration should look like mine. /dev/hda1 corresponds to (hd0,0) If you do have a separate /boot partition, then you should have the root line correspond to that, and your kernel and initrd lines should not contain the /boot. on the third line (the one starting kernel) the root= option tells your kernel where it can find the / partition. the root=LABEL=/1 is just another way of specifying this without having to specify it physically, if you take advantage of partition labelling (it seems that fedora does by default) the initrd line seems to be the magic line that you'e missing from your stanza for this kernel. This problem is now solved. I was helping Wayne get rtlinux installed. The solution was to use root=/dev/hdb1 in the kernel line in place of the LABEL construct. Changed this in both stanzas and in fstab. I don't understand why the LABEL construct worked for the redhat installed kernel and not for the rtlinux kernel. As I understand it, the LABEL construct allows grub to search for the right partition which is supposed to make it more robust to hardware re-configuration. Maybe the rtlinux patches to the kernel broke something needed for the LABEL construct to work. I definetely had the initrd line in the stanza.
