It's a battle as old as time: good vs. evil. Fortunately, Linux and FOSS are on our side as we wage the battle against those who try to steal our secrets and invade our systems.
Checking your system's security is best done sooner rather than later. Test the locks with our article on security verification; find out how to use PAM to help secure your systems; use MinorFS and AppArmor to implement discretionary access control; learn more about Samba security in part III of our series; use Darknet to help detect bots and secure your systems; use the Yubikey to increase your site's security; and don't forget to lock the doors, because a cold boot attack could render your security useless if somebody has physical access to your computer.
But, we're not just about sowing the seeds of fear. We also show you how to use memcached in Rails, how to manage multiple servers efficiently, how to deploy applications easily with Capistrano, how to manage your videos with MythVideo, how to mix it up a bit (your audio that is), and even play a few games.
RE: What does 'reliable' mean?
On November 7th, 2007 Anonymous (not verified) says:
I trust reliable is referred to in the sense that some functions makes the entire signaling handling reliable, e.g. 'sigaction' may block signals and set a new signal handler in one atomic swoop, as to eliminate the potential race condition.
As to your last question, if the signal is not blocked and a new instance is generated in the midst of the processing of the last one, then the signal handler must be re-entrant. IMHO, the best method is to block the signal on entering the signal handler. It will be automatically restored on exit. On old UNIX versions, once a signal handler is invoked, the signal handling is reverted to default. If a new signal instance comes along, it will be treated the default way, most often terminating the process.
