Meeting presentation - email encryption.
Have we ever done a presentation on email encryption? I know SFA about it and would like to. Cheers Don

Steve wrote: Do you mean encryption of an email, or the sending medium - TLS, IMAPS, etc?? Encryption of an email. Setting up SSL on the transport medium isn't a big thing to do these days is it? You do raise an interesting point though... How do I protect the messages on my IMAP store? How do I keep sys admins out of my content and still be mobile with something like web mail? However what I was thinking was more along the lines of... I want to send Nick an email that only Nick can read. How do I do it? I want nick to know that the message he got did come from me and wasn't tampered with along the way. Is that possible. thurnderbird has an 'encrypt' button. What do I need to do to make that button functional. What tools are there for sending/receiving email that are easy to use eg. Assume different levels of security... As always, I assume the more 'user friendly' you make things, the less security there is. ie. If my 'email client' unencrypts a message then stores it as plain text on my laptop then it's not hard to get the messages by taking my machine, however the message is still secure in transport. What different levels of security are there? 48bit, 128bit? What's the norm to use at present? What's best practice? Does that give you enough info for a presentation Steve? (Hint hint, nudge, nudge, wink) Cheers Don
Mandriva questions
Do we have any Mandriva experts on the list? I have some questions about how to install a source package and do a custom build, but thought I'd check first if there is someone here who can help me. Cheers Tom Munro Glass
Re: Mandriva questions
Hi I have been running Mandriva since before mandrake 8. 1st question ... what is the app, is the src in a .mdk package? If so, install the pkg as per normal, it will go into /usr/src/whatever. If it is a tar or similar pkg unpack it to /usr/src/... Konqueror is excellent for this. Open 2 panels, unpack in 1 panel, goto usr/src in the 2nd panel, then drag n drop the appropriate dir across. From there it is a normal compile but test before you install. You will need the src package for your kernel installed before you compile. If the compile bombs there may be other pkgs you need to install also. HTH Barry --- Tom Munro Glass wrote: Do we have any Mandriva experts on the list?

I have an application that I have written that uses Qt4 and in particular it needs to use the Firebird/Interbase driver. There doesn't appear to be a package for the IBASE SQL plugin, so I figure I need to build Qt myself. So I downloaded the qt4-4.3.4-6mdv2008.1.src.rpm package and tried to install it. First Mandriva warns me that I probably don't want to install it because it's a source package, but I say install anyway, but nothing seems to happen - I can find no trace of the source files being installed. I can always download the source from Trolltech but I'm curious why Mandriva won't install from the package. If I can solve this problem, the next step is that I need to compile Qt4 and then make a package that can be used to install the IBASE plugin on other systems. I'm not really sure where to start with this. Cheers Tom

Re: Mandriva questions
What version of Mandriva are you running, The package is available for 2007 and 2008. looks like 2008.0 and 2008.1.

Is it the Free or Powerpack (purchased)? There should be no need to rebuild QT from source, make sure you have ALL the QT and firebase -devel libraries installed. If you feel you must use the .src files the correct commandline is: rpm --rebuild filename (executed as root) John

Searching the media on this site and any other mirror I have looked at, there are only 4 SQL plugin packages available: qt4-database-plugin-mysql-lib-4.3.4-6mdv2008.1.i586.rpm qt4-database-plugin-odbc-lib-4.3.4-6mdv2008.1.i586.rpm qt4-database-plugin-pqsql-lib-4.3.4-6mdv2008.1.i586.rpm qt4-database-plugin-sqlite-lib-4.3.4-6mdv2008.1.i586.rpm What I clearly need is qt4-database-plugin-ibase-lib-4.3.4-6mdv2008.1.i586.rpm but this doesn't seem to exist, so that's why I believe I will have to build it. I have now compiled the Qt source from Trolltech and it created the library file libqsqlibase.so. I copied this into the directory /usr/lib/qt4/plugins/lib/sqldrivers and my application now works. I don't know why the ibase driver is not included along with the other 4 drivers, but as far as I can the package only needs to install the file libqsqlibase.so so hopefully I can make a package.
