Linux tools for PDF processing

In the company where I work, we have some very nice Canon ImageRunner copy machines. One of the advantages of these machines is that they have fast and good quality scanning possibilities, so they can be used for scanning bigger quantities. In normal cases you can set up these machines to send the scanned documents to email addresses, or to store them directly on computers, but in my company the email size is limited to 10 megabytes and we have chip card authentication, therefore I can not set up the copy machine to store documents directly to computers.
But nothing is lost, because the ImageRunners have a web interface and I have written a small tool, to download the scanned documents from the copy machine to a local folder. The only disadvantage is, that you can only download the documents page by page, the color images in re jpg format and the black and whites in tiff.

Here are some tricks what I have used to convert them to PDF documents.

AJAX Network Control Center for Ericsson W25

I have a relatively complicated network setup at home and wanted to create a frontend to them, where I can easily switch on/off the servers, manage the server and router configurations, see if the internet is up and running ans see how many client computers are connected.

After evaluating some options I conluded to use an AJAX based solution, running on the Ericsson W25 3G router. The idea was to have a schematic diagram showing all the computers on the newtork, with buttons on the computers to do management tasks.

So here is the result:






As you can see there are boxes for al routers and computers, with the power button you can swicth on or off the servers or restart the internet connection. With the setup button you can go to the management web interface for the servers or routers. In the bottom of the picture you see the clients who have got IP address, their status is checked with arping, so even with a switched on firewall you can see the status.
