comment Ansible Fails to Authenticate Sudo Even When Sudo Pass is Given
I would argue that Ansible giving precedence to file-defined variables over command line options is counter-intuitive, and bad behavior. Curiously, it does recognize that this is broken when you pass options with -e, and you may be able to work around this by passing an appropriate option with -e.

comment iptables: match only the first packet of established TCP-connection
While I have no doubt that IPTables can be shoehorned into performing this function, I'd recommend you consider other options. This sort of filtering is best done at a Web Application Firewall (like ModSecurity for locally installed, or CloudFlare for hosted; F5, Citrix, and many other companies offer commercial solutions, too). Using IPTables to do a string match against a specific packet in a TCP connection to catch a web request is like using a hammer as a flyswatter. Sure, you could kill the fly, but you're going to do a lot of extra work and risk collateral damage.

comment Cron not launching python script
The problem is almost certainly your problematic use of screen. What is the purpose you are trying to accomplish with that? Have you tried it without using screen anywhere?

comment NFS performance woes on Debian
@anarcat - For modern releases, you're correct, nfsvers=3 won't matter as much. Linux NFS mounts used to default to NFS version 2, unless you specified version 3. In those cases, it was very worthwhile to explicitely set the version. In modern releases, mount will negotiate, starting with v4, then trying v3, then falling back to v2.

comment postgres server fails to start, produces no log, how to to troubleshoot?
@chrismarx - The service command is just a convenient wrapper around the /etc/init.d/ script that actually starts and stops the process. You'll need to look at that script to see what it's doing differently from when you manually run it. Doing something like bash -x /etc/init.d/postgresql start might be a good place to start your research.
