They have nothing to do with each other. You can use any editor to create python progams. To learn python, install the python docs package that comes with a tutorial.

Do you need more help?X

Argh, you're right. That's a better way to go.

If there is more than one card that could match the ATTRS{name} field, the OP could add another criteria that matches on the PCI slot number (so two cards don't fight for the "lirc0" name):

KERNEL=="event[0-9]", ATTRS{name}=="cx88 IR *", KERNELS=="0000:01:09.2", SYMLINK+="lirc0"

Because you're changing something that has to do with things that automatically happen on boot. I'd rather discover a problem now while I remember what I did, than the next time I boot (a year from now?).

Unless you have production services going on, a quick reboot is a good idea. If you do have production services, schedule the reboot for the next short maintenance window and be doubly sure that you've logged what you've done.

Can we help you?X

I suspect they rely on internet explorer being the browser, install some sort of activex control and retrieve whatever information they can about the users' computer. (This can potentially include sensitive information)

If it is not a requirement for you to deal with this particular financial institution, I recommend switching to someone else having better standards support (and inform the original institution about it and your reasons for the change).

Otherwise, try the version of adobe reader that is available for linux, though I guess they won't be able to detect that it is installed if you access their site using linux. If this check for 'reader' is a one time process, you can probably try connecting to their site from a trusted windows machine with adobe reader installed, get through with the verification step and then continue your transactions from your normal machine.

Create a file .xsession in your home directory with the following: ===cut===
source ~/.bashrc
PATH=<your path>
exec gnome-session
===cut===

Log out of gnome and log back in specifying the session as "User default" or some such thing in the gdm menu.

I discovered motion, but I think that it is a bit too complex for this stage of the project. And I found three other webcam server HOWTOs. But I still am confused as how to get the system working.

Do you need help?X

I also discovered "sftp", which may be the solution I am seeking.

I wish to be certain that my desktop system is not compromised if someone steals the remote system; so if the remote system runs a script for ftp via ssh, the password or passphrase contained in the script should be exclusive to ftp. Am I making sense?

I beg to differ as motion is pretty darn simple to setup and operate, but you are welcome to use whatever solution you like.

I'm not sure. sftp merely provides ftp service tunnelled through ssh and gives access to ssh niceties like pubkey authentication. What specifically are you trying to do with ftp? If you want to be able to login remotely and pull images from the remote camera box, then certainly, sftp (or any number of other things) would work. If you set up pubkey authentication, then you're pretty secure at the remote end and there is nothing in the remote end that allows access to the local end. If you're trying to *push* images from the remote end to local, that's a different story. Pushing means you've got to run your authentication the other way and expose your local end to compromise =66rom a compromised remote end.=20

Can't find what you're looking for?X

So, maybe you could lay out exactly what you want to have happen, again.=20

also, if you are just tying to grab remote images every so often, and you have a web interface setup, you could just script wget to scrape the page every so often and save it locally. just a thought.

How old is the current version of Imagemagick in testing? Any idea if it will fix this known issue:

convert: Delegate failed `"mpeg2decode" -q -b "%i" -f -r -o3 "%u%%d"'.

Confused? Frustrated?X

If a couple of reboots is ok for you, the following method might work.

You can use 'dd' to clone hda2 to hda1. Boot your system with "init=/bin/bash". When you get to the bash prompt, do

bash# dd if=/dev/hda2 of=/dev/hda1

When that completes, you would have your installation available on both the partitions. The 5GB hda1 would contain a filesystem that is only 1GB large. Restart your system. You would boot normally with a 1GB root.

Edit "/boot/grub/menu.lst" and add an entry for the linux on hda1. set root to (hd0,0) and append root=/dev/hda1 for the kernel line of the new entry.

mkdir /tmp/newroot; mount /dev/hda1 /tmp/newroot

Edit the file /tmp/newroot/boot/grub/menu.lst and replace (hd0,1) with (hda0,0) and root=/dev/hda2 with root=/dev/hda1. Similarly fix the root filesystem entry in /tmp/newroot/etc/fstab by changing /dev/hda2 to /dev/hda1.

Now you should be able to boot into either of your two partitions.

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

Once you have satisfied yourself that both are working, boot into your 1GB partition, and resize hda1. The command "resize2fs /dev/hda1" should be sufficient.

Restart into the 5GB parition and now you would have a 5GB root with over 4GB free space.

Run "grub-install /dev/hda" so that grub can load itself from the new location.

You can now copy over your home directory from the 1GB partition and continue using hda1. If you wish you format hda2 and mount it as /home.

Feel free to post any problems you may have and make sure you take a backup of important files before proceeding.

Good luck,
rajkiran

Thanks, Andrew. This is the type of dialogue I need. I'll take another look at motion.

I had not given much thought to this approach; but I could implement it inexpensively with the aid of a dynamic dns service. It would be much like fetching mail from a pop server.

That is the approach I had in mind, and that is why I was concerned. But if the local machine goes out of service, there is no monitoring. So the first approach would be better.

Initially, all I need is the ability to glance at the remote site now and then, using a single webcam, in order to satisfy myself that all is well. It would be dandy to be able to listen in, also, using the microphone on the webcam. I was not attempting to provide comprehensive security monitoring. It would be nice if I could check on the remote site from a machine of a relative or friend. But they all run Window$, so that necessitates that I implement a web server, either at the remote site or else at my home. If the web server is at home, then the home machine is exposed to attack (as well as to frequent lightning storms). The issue with the remote system is not so much security as it is keeping the system up and running despite hackers. I cannot afford to reinstall the system every week. So I plan to use an external firewall to protect the remote machine.

Again, like automatically fetching the mail. RLH End of debian-user-digest Digest V2007 Issue #2532 ************************************************** Received on Tue Oct 2 01:24:09 2007
