How to make new file permission inherit from the parent directory?
I have a directory called . Then I am running a script under the user id 'robot'. robot writes to the directory and update files inside. The idea is is open for both me and robot to update. So I setup the permission and owner group like this where both me and robot belongs to the 'robot-grp'. I change the permission and the owner group recursively like the parent directory. I regularly upload new files into the directory using . Unfortunately, new files uploaded does not inherit the parent directory's permission as I hope. Instead it looks like this When robot tries to update , it fails due to lack of file permission. I'm not sure if setting umask helps. In anycase the new files does not really follow it. I'm often confounded by Unix file permission. Do I even have a right plan? I'm using Debian lenny.

Compressing with RAR vs ZIP
A lot of people are compressing files with RAR, sending compressed files with RAR and so on. ZIP is more standard and works on all platforms. Windows users have ZIP included and Linux users have no trouble with that file format. The tests I did sometime ago showed me that RAR compress better (some kilobytes, no more) but not enough to use a non-free program when ZIP works on almost all computers for free. Why do some people use RAR rather than ZIP for compressing?

Compress and then encrypt, or vice-versa?
I am writing a VPN system which encrypts (AES256) its traffic across the net (Why write my own when there are 1,000,001 others already out there? Well, mine is a special one for a specific task that none of the others fit). Basically I want to run my thinking past you to make sure I'm doing this in the right order. At the moment packets are just encrypted before being sent out, but I want to add some level of compression to them to optimize the tranfer of data a little. Not heavy compression - I don't want to max out the CPU all the time, but I want to make sure the compression is going to be as efficient as possible. So, my thinking is, I should compress the packets before encrypting as an unencrypted packet will compress better than an encrypted one? Or the other way around? I will probably be using zlib for the compression. Read more on the Super User blog.
