I have 2 PCs that are connected to wireless router, which is  connected to a cable modem.

The two PCs form a private network. I want to know the IP used by Interne= t user to access one of PCs.

I do not believe that it is a kernel issue; I just mentioned the kernel t= o
indicate that I have a standard "Etch" install - no upgrades!.

I suspect it is due to some of the major rationalisations there were introduced in Etch and have not yet been taken onboard by EPSON/EPKOWA in its supplied plugins.

The error message - when iscan cannot find the scanner - reads:  /usr/share/iscan/esfw54.bin/esfw54.bin : Not a directory

Can we help you?X

This error message is valid.

"esfw54.bin" is not a directory but a file and it is located in "/usr/share/iscan/" (I have placed copies in a few other places - just in case the alternatives locations can be found more easily by "iscan").

Subject: dpkg not changing files in /boot after kernel upgrade 

Message-ID:  
Content-Type:  text/plain; charset=us-ascii
Content-Transfer-Encoding:  7bit

Hello.

I have been using the 2.6.18-4-powerpc kernel on my system for a while now because, when the 2.6.21 kernel came out, it introduced a few bugs that significantly diminished the performance of the system. I wanted to see if the newer 2.6.21 still has this problem of if it has been repaired.

I opened aptitude and installed linux-image-2.6-powerpc, which also installed linux-image-2.6.21-2-powerpc. The packages were apparently installed successfully, but when I rebooted, it booted into the old kernel.

I looked at the /boot directory, and none of the links had changed. Here's the output from when I reconfigured the kernel packages:

Running depmod.
Finding valid ramdisk creators.
Using mkinitramfs-kpkg to build the ramdisk. Not updating initrd symbolic links since we are being updated/reinstalled (2.6.21-6 was configured last, according to dpkg) Not updating image symbolic links since we are being updated/reinstalled (2.6.21-6 was configured last, according to dpkg) Examining /etc/kernel/postinst.d.
run-parts: executing /etc/kernel/postinst.d/mkvmlinuz

Why is it not updating the links - I had a version of 2.6.21, but I removed it a long time ago. Is there a way to get dpkg to realize that it does need to modify the symbolic links?

Don't know where to look next?X

Thank you for any help,
Sean

If you have the ability to store and run a CGI script remotely, run something like this...

#!/usr/bin/perl
use warnings;
use strict;
my $myip = $ENV{'REMOTE_ADDR'}; 

print "Content-type: text/html\n\n";
print "my ip: $myip

print "";

exit;

Use a debian rescue disk and use the find command on that rescue disk to locate directories without printable names. The ugu tips site recently featured a tip to rename these directories so they become printable. Don't trust the find or aqny other utility on a hard drive when doing this kind of searching only removeable media that can't be overwritten.

Subject: debconf-set-selections + dpkg-reconfigure: why don't my settings stick? Message-ID: <slrnfgdfdr.f8t.ahuxley@dione.no-ip.org>

I would like to configure some packages "the Debian way", but non-interactively,

I used debconf-set-selections to set the settings I wanted. Then I used debconf-get-selections to verify that the setting had been correctly registered.

Finally I ran dpkg-reconfigure in non-interactive mode on the packages expecting that the just-set settings would be applied, but in all cases I get the previous setting being applied, i.e. as if I had not run debconf-set-selections at all.

Am I missing some step here?

Call Pantek today for Open Source Technical Support at 1-877-546-8934 - 24/7/365X

Here's an example:

nidi# echo -e "tzdata tzdata/Areas select Europe\ntzdata tzdata/Zones/Europe select London" | debconf-set-selections nidi# debconf-get-selections | grep tzdata 

tzdata  tzdata/Zones/Australia  select
tzdata  tzdata/Zones/Asia       select
tzdata  tzdata/Zones/Etc        select  UTC
tzdata  tzdata/Zones/SystemV    select
tzdata  tzdata/Zones/Africa     select
tzdata  tzdata/Zones/America    select
tzdata  tzdata/Zones/Arctic     select
tzdata  tzdata/Zones/Pacific    select
tzdata  tzdata/Areas    select   Europe
tzdata  tzdata/Zones/Antarctica select
tzdata  tzdata/Zones/Atlantic   select
tzdata  tzdata/Zones/Europe     select  London
tzdata  tzdata/Zones/Indian     select

nidi#

It now looks like the setting I want, but when I reconfigure:

nidi# dpkg-reconfigure -f noninteractive tzdata

Current default timezone: 'Etc/UTC'
Local time is now: Fri Oct 5 22:31:17 UTC 2007. Universal Time is now: Fri Oct 5 22:31:17 UTC 2007.

nidi#

I poked around in the postinstall script of the packages I tried (tzdata and locales) and I think that the script puts the actual setting in effect (e.g. as defined by /etc/timezone or /etc/locale.gen depending on the package) at a *higher* priority than the value in the debconf database.

I can understand this: if someone does things in the traditional edit-the-config-files way, then that setting is not reset by using dpkg-reconfigure etc.

Do you need help?X

But nevertheless, it should be possible to have dpkg-reconfigure apply the setting I've seeded its db with? Is there nothing like

dpkg-reconfigure --settings-in-debconf-db-get-higher-priority-than-values-found-in-the-field

?

Any advice appreciated!

Alexis

If you need to do it in a script, you might prefer something along the lines of:

Well my xserver-xorg was upgraded on Monday September 17th --- I didn't install the console package until a day ago...so I assume if there was no problem earlier that it is related to the upgraded package.

My gv can give this to me, there is a small gray box to the left beneath the File drag down button which gives the position of the mouse ... but you have to do the calculations yourself (like use the pythogoras rule if your not measuring a horizontal or vertical line) to find the distance between the points.

Awesome. Now I have several tools to look into. Isn't that just the way it is, so often when it seems hard to do something, you ask for help and end up with several ways to do it. That is one reason why I am glad I switched to Debian. Thanks very much for all the help guys. Patrick

Most, if not every, home router made in the last 5 years has an embedded web server and an internal IP address. So if the external interface is down and thus can't get to ipchicken or whatismyip, connect to that web server and it will tell you what the external address is. - -- Ron Johnson, Jr. Jefferson LA USA Give a man a fish, and he eats for a day.

Libraries (to call from C, C++, Fortran 90 codes): Petsc - pretty much everyone in the numerical analysis community rely on this for solving large scale linear problems. Has good parallelization (MPI) support, lot of sparse, direct solvers etc., lapack95 - Good if you are using fortran as your programming language. Has been around for sometime. Code is well tested but does not have as many routines as petsc. No parallel solvers or sparse solvers AFAIK. IMSL - proprietary. Software suites: Matlab - proprietary, comes with a good GUI, lots of routines to plot graphs, contours etc., contains lot of sparse solvers. Octave - Use versions > 2.9.12 for better experience. Older versions are incompatible with newer versions. Does not have a GUI provided by the upstream, plotting capabilities are kind of limited. Does not have that many sparse solvers. But if it works, it does the job well and the code is actively developed. It integrates well with Linux (for example it uses gnuplot for plotting, lapack for solving system of matrices etc.,). My recommendation is to go either with octave or with petsc depending on what you are looking for. hth raju -- Kamaraju S Kusumanchi http://www.people.cornell.edu/pages/kk288/ http://malayamaarutham.blogspot.com/

My scanner is a USB connected Epson Perfection 1260. It worked perfectly under Mandriva Linux; however, Xsane under Debian shows no devices available. lshw recognizes the scanner but shows the usb as unclaimed: *-usb:0 description: USB Controller product: VT82xxxxx UHCI USB 1.1 Controller vendor: VIA Technologies, Inc. physical id: 10 bus info: pci@00:10.0 version: 80 width: 32 bits clock: 33MHz capabilities: uhci bus_master cap_list configuration: driver=uhci_hcd latency=32 resources: ioport:d400-d41f irq:11 *-usbhost product: UHCI Host Controller vendor: Linux 2.6.18-5-686 uhci_hcd physical id: 1 bus info: usb@1 logical name: usb1 version: 2.06 capabilities: usb-1.10 configuration: driver=hub maxpower=0mA slots=2 speed=12.0MB/s *-usb UNCLAIMED description: Generic USB device product: EPSON Scanner vendor: EPSON physical id: 1 bus info: usb@1:1 version: 1.00 capabilities: usb-1.10 configuration: maxpower=2mA speed=12.0MB/s lsusb also lists the scanner: tomshome:/var/log# lsusb Bus 004 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 Bus 002 Device 001: ID 0000:0000 Bus 001 Device 003: ID 04b8:011d Seiko Epson Corp. Perfection 1260 Photo Bus 001 Device 001: ID 0000:0000 syslog does not mention the scanner. I have not been able to find the answer through google or the Debian User list archives and will appreciate any help you can provide. Thanks much, Tom Ashley End of debian-user-digest Digest V2007 Issue #2567 ************************************************** Received on Fri Oct 5 23:04:48 2007
