RHCT exam prep

[alinuxFF]

I am studying for the RHCT exam using, primarily, Michael Jang's RHCT Linux Study Guide. I've noted a few errata - or at least some places where the commands and instructions in the text don't work with Fedora Core 4 and, presumably Enterprise 4 (which the exam will be based on). I have written to the publishers but have had no reply. Is there anywhere where those of us studying this text, or just for the exam, could exchange ideas/informatiion? I fully understand that trying to get information about the exam questions itself would be frowned upon by the RedHat organisation - rightly so. But getting up-to-date information of errata in texts should be fine. Any possibility of starting a forum even just for errata (or updates) in texts?

Here's a contribution of errata for what it is worth:
The first problem is on p 245 where he mentions the command redhat~config~services. The command should read "system-config-services". Note that "redhat" is replaced by "system" and that the tildes are in fact dashes. This is the case for Fedora Core 4 and Redhat Enterprise AS 4. The error is repeated in several pages following this first instance.

The second problem is on page 248 where he states that you can use alt F2 to open a virtual console. In fact you have to press ctrl-alt-F2 to do this. He further compounds this by saying you can move between them using alt and the arrow keys. You can move between different windows, not virtual consoles, using ctrl-alt-arrows.

A third problem is using SSH to run remote X applications. You need to add ForwardX11 yes to the local /etc/ssh/ssh_config file before you will get the x application to display.

Previous versions of RHEL used to use the redhat-config-* command. RHEL v.4, I think, is the first to use system-config-*. The virtual consoles can in fact be opened using alt and the function keys when you are in run level 1-3. You only need to use Ctrl when you are in X. I'm not sure about RHEL but Fedora has X forwarding turned on by default. What version of RHEL is the book geared for?

Jang's book is written for RH Enterprise 3. So it is fair enough that it doesn't always work with later versions of Fedora and RedHat - which is just my point. We need somewhere to record errata and updates if the publisher won't.

Ooops .. I've just edited my entry to adding yes after ForwardX11. In the local /etc/ssh/ssh_config file there is a line ForwardX11Trusted yes so this is on by default - but until I had written the other line, the display wouldn't show the X application. According to Negus in the Red Hat Fedora and Linux Enterprise 4 Bible (p 220) the "X forwarding is off by default in Fedora Core 4...".

Interesting, I have just installed Fedora Core 4 last night and the X11Forwarding is set to yes. I have not made any adjustments to it.

I have a friend who took his RHCE exam this past year (last spring?) right when the exam requirements were changed from RHEL v.3 to RHEL v.4. He ran into a couple problems regarding the discrepencies between the versions and ended up failing the exam. Needles to say, I think it is a good idea to have a place where we can list errata and changes/updates so more people can easily find the information.

i've made the RHCT certification september last year (based on rhel4). now i'm preparing for the RHCE exam in march.

your first two problems reside on the different versions. your book was written for rhel3 (at least the copy i have) and you'll being tested on rhel4. the first problem is right: redhat changed the redhat-config-... utilities to system-config (due to the pressure of the fedora community).

to the second problem: you can switch with alt+fn between virtual consoles and alt+left or alt+right (if you're not in the GUI). if you are in GUI (xserver) this will not work.
by the way: the most configuration you do better in a single console, its faster and you won't have so much time...

to your third problem: try ssh -X [host]. so it worked on my machine. for further advises see here: remote x applications (http://www.fedoraforum.org/forum/showthread.php?t=91013&highlight=remote+application)
