I’ve just put another batch of Linux articles live.
- Linux Access Control Lists (ACLs)
- Linux Archive Tools (tar, star, gzip, bzip2, zip, cpio)
- Linux Services (service, chkconfig, system-config-services)
- Linux System Log Files
- Linux Network Configuration
- Linux HTTP and FTP Server Configuration
- CRON : Scheduling Tasks on Linux
- Access Remote Servers from Linux(ssh, vncviewer)
As before, they are focussing on the RHCSA exam objectives, so a lot of it is pretty basic information.
The Firewall and SELinux objectives are the only ones left now. These two objectives were the main reasons I decided to start this process. I left them until last because I figured if I started with them, I might never get round to doing the other articles. 🙂
As far as the Linux firewall goes, if it can’t be done with the point and click GUI (or TUI), I don’t do it, so taking a look at iptables from the command line has been on my list for a very long time. The RHCSA objective suggests using the GUI/TUI interface should be sufficient, since it says, “using system-config-firewall or iptables”. In contrast, the RHCE objectives explicitly mention iptables, possibly suggesting tasks that may not be possible from the GUI? The question is, how much do I trust my own judgement on this matter? I would prefer go in to the RHCSA exam with too much information, rather than not enough, so I guess I’ll take a look at iptables from the command line before attempting the RHCSA exam.
I know even less about SELinux than I do about the firewall. For Oracle installations I typically disable it. 🙂 So I guess this objective is going to be a magical mystery tour. 🙂
If anyone has sat the RHCSA exam for RHEL6, I would be interested to hear your thoughts on the Firewall and SELinux objectives. I think I’ve got a pretty good handle on the other objectives, but I’m kinda shooting in the dark with these two. It would be a shame to waste £400 on a failed exam. 🙂
