This is probably common knowledge, but I recently discovered the -u flag. This is handy, since I routinely use three different smarthosts. So when I plug my laptop into a different network, I switch the comments in my /etc/exim4/update.conf.conf file to point to the right smarthost:

  dc_smarthost='smtp1.ns.sympatico.ca'
  #dc_smarthost='smtp.smu.ca'
  #dc_smarthost='mailhost.mcgill.ca'

Do you need help?

and then run

dpkg-reconfigure -u exim4-config

This way, dpkg-reconfigure just switches the smarthost, without making me answer a bunch of questions about things that don't change.

At some point I suppose I should write a script that will check which network I'm on and invoke dpkg-reconfigure exim4-config with the right options, but I'm not sure how to do that yet - any hints welcome!

Cheers,

Tyler

Can't open SCSI driver!

Note that I am using the linux-image kernel, not a kernel compiled from a linux-source kernel package. Apparently the linux-image kernel is not compiled with scsi emulation.

/dev/hdc I can mount it as /media/cdrom0 and read data files from a cd

The output of less /proc/ide/hdc/driver is ide-cdrom version 4.61

The output of lsmod includes ide_cd and cdrom which uses ide_cd.

Can we help you?

insmod sg finds no such module.

Can't find what you're looking for?

In lsmod I find ide_cd and cdrom uses ide_cd

I am using a linux-image-2.6.18 kernel. Apparently it was not compiled with SCSI emulation as this should not be needed.

Don't know where to look next?

Need to correct myself here: The correct address is report-listspam@lists.debian.org

Message-ID: <BAY104-F28F618CB616BCDEA4ECE3691C00@phx.gbl> Content-Type: text/plain; format=flowed Dear Debianists, I am interested to get a camcorder and use it along with Debian..... I got myself a copy of Digital Video Oct 2007 magazine. In there is a useful review of a wide range of camcorders. The general picture I get from reading the magazine and various web pages and av forum pages is that people seem to think that mini DV is the better format for relatively low priced camcorders. Hard Disk ones work OK but the quality is not quite as good as tape cameras at the same price. You can also get DVD camcorders. They have a DVD disk in there that is smaller than a regular DVD that you would use e.g. to install Debian with, but conventional DVD optical drives can apparently read these smaller video DVD disks. Again the magazine and web pages seem to say that the quality of the DVD camcorders are not quite as good quality at a given price in the budget range as mini DV camcorders. I guess the advantage of the DVD and hard disk cameras would be one of convenience in that you could transfer footage to the computer hard drive very quickly and without fuss. If you want to copy the footage to the computer from the mini DV tape camcorder you apparently have to use a firewire cable. I assume this means that I will have to attach a firewire card to my PC..... There is an IEEE 1394 connector on the board apparently. I am using an AMD64 box with an AMD64 Sempron 3200 chip and a socket AM2 board I got from novatech...... It also has PCI and PCI Express slots in it. It is the K8M890M2M4 motherboard sold by Novatech to be precise. I don't have a graphics card yet but I will get one soon. In the buyer's guide in the Digital Video magazine (published by Future Publishing who also produce the Linux Format magazine) the editor's choice for a camcorder in my price range is a miniDV camcorder made by JVC. The model is the JVC GR-D340. It retails for around £300 ($600). You can get it at a discount on the internet (£200). Apparently it has a selection of automatic exposure modes, wipes, fades and 16:9 shooting. As far as I understand it the 16:9 mode is for widescreen TVs. It also has a 32x optical zoom. The audio performance is also good and so is picture quality. It got an overall rating of 94%. I think I would buy this camera...... However, I went into Curry's electrical store at the weekend and they had a camcorder which had 3CCD technology in it that was retailing for around £200............... The guy in the shop said this was superior to single CCD camera technology. Am I missing out here? In practice, is it a pain having to copy tapes slowly for an hour etc or so through the firewire on to the computer? Are the results really that much better with the tape cameras? In reality I would film some stuff, copy it on to the PC and edit it to add some subtitles, some graphics and desktop software slides etc... nothing fancy..... Plus audio commentary. I guess that Blender could do some editing and also graphics. Recommendations for other software to do this would be appreciated. People have suggested kino to me before on this list. Comments appreciated. Regards Michael Fothergill _________________________________________________________________ The next generation of Hotmail is here! http://www.newhotmail.co.uk

Message-ID: <46E54DD5.3050406@ntlworld.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Hi, I'm using MySQL 4.1 on Etch and have a database (that I created) on another machine (still Sarge) that I want to transfer to the other before upgrading to etch on that machine also. Where should I look to find out how to do this? Is it just a matter of locating the database and copying or is it more subtle? Are there any security considerations? On the security note, I'd also like to be able to access the database from other machines but am unable as by default remote access to the server isn't allowed - again, where should I be looking for information on how to change this? The MySQL docs are pretty daunting for a database newby, and I was hoping there'd be some debian-specific documentation somewhere... Thanks if anyone can help point me to the relevant information source, Martin

SCSI emulation is probably compiled as a module. Put this on the kernel command line: hdc=ide-scsi That should allow the SCSI emulation driver to take control of that interface. You might have to "modprobe ide-scsi" after bootup.

how about ``set -x'' and let the shell do it for you ? End of debian-user-digest Digest V2007 Issue #2347 ************************************************** Received on Mon Sep 10 11:08:02 2007
