General :: Red Hat Training And Certification - Course Pre-requisites?
Mar 2, 2011
Experienced sys admin with over 20 years experience of Solaris and HP-UX, but limited Red Hat knowledge.
I dont want to do the basic linux courses and spend days learning how to use vi etc.
I was thinking of jumping straight in and doign the RHCSA Rapid track course or even the RHCE Rapid Track course.
Of course, if I ask Red Hat they'd tell me I had to do the courses before this.
Unfortunately, funds are limited (personal training grant) so its one course only.

I am having an issue with HTTPS certification using curl. My curl is configured with OpenSSL. If the certification verification is failed I dont want to terminate the operation, instead I want to continue by just putting a log message. For this I have used OpenSSL SSL_CTX_set_verify() function to set my static C callback function. During HTTPS transaction, my callback is also getting called with first parameter 0 or 1 (depending upon of the certificate verification is success or failure). But even if my certification verification is failure, I want to continue. So I have hard coded to return value as 1 always from my callback function. But still I see the certification error and I don't get the page.

I keep training SpamAssassin with the spam that slips through, but don't see any improvement is spam detection. The details are these: Using ssh I trained SpamAssassin with examples of spam and ham I had saved for that purpose, perhaps 500 of each. I set up email recipes such that spam@example.com would go through sa-learn --spam --mbox, and ham@example.com would go through sa-learn --ham --mbox. Since then I have forwarded (as an attachment) any spam that slips through to spam@... and an equal amount of fresh ham to ham@...
That worked well for about a year. Spam in the inbox went from 150 per day to less than one per week on average, with no false positives. Naturally, spam blooms sometimes appeared, but training dealt with them.
I wrote up my spam setup in greater detail in these notes to myself:[URL].. For the past month or so, however, a steady stream of nearly identical spam has been getting through and despite training it all I see no change in spam scores on it. Here are relevant headers from a typical message:
(snip)
X-Spam-Status: No, hits=-6.6 required=3.5
tests=BAYES_00,RCVD_IN_DNSWL_MED,STOX_REPLY_TYPE autolearn=ham
version=3.002005
(snip)
X-AVES-Antispam: Maybe spam, 17.32 >= 4.00 [as:15.30 cc:0.00 hc:2.02
sa:17.32]
(snip)
Notice that a spam filter on an upstream server correctly flagged it, but my SpamAssassin. Nor does the score on these nearly identical messages seem to change with training. Another clue: previously my spam folder was receiving fresh spam every hour. Since this problem began the spam folder receives almost nothing.
Sure, it would be easy to cook up a procmail recipe to filter on the upstream server's "maybe spam" header, but I'd rather fix the underlying problem with SpamAssassin, not cover it up. Prior to coming here I searched the web, consulted my web host's knowledge base's articles on SpamAssassin, and read everything relevant at spamassassin.apache.org, but I remain stumped.

My Ubuntu system is occasionally becoming very sluggish. I'm running many things simultaneously and it's very difficult to tell which program is the culprit.
I suspect that the sluggishness is due to disk activity since the CPU usage is consistently under 50% on each of the 4 cores of the CPU, and over 30% of the 6GB of RAM are free.
Is there a tool that can show me in real time the number of disk IO operations per second and the amount of data read/written per second? Can all this info be broken down and displayed per process?

I'm using my Linux (SLES 10) server as a File Server at this point. I need to set File Permissions to nested folders differently to different groups. For example:
homesharedengineering* should be read only for groupA
homesharedengineeringadmin should be read & write for groupB Plus read only for groupA
homesharedengineeringautocad should be read & write for groupC Plus read only for groupA
I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?

PackageKit is a system designed to make installing and updating software on your computer easier. The primary design goal is to unify all the software graphical tools used in different distributions, and use some of the latest technology like PolicyKit to make the process suck less.

II'm a front-end web developer, I've always developed on Windows with technologies like XHTML, CSS, Javascript and Flash, I've dabbled with PHP and MySQL. I am well used to Windows workflows and tools, from Photoshop to Notepad++, Filezilla and WAMP server stacks to After Effects, and a swathe more - but always on Windows.I'm at a point where I think I need to start seriously developing on a Linux box, specifically at the moment to create web apps based on Node.js, but compiling tools and programs has become a task I'm more frequently required to do.
My question? I need to get my hands on a user-friendly install of Linux, but which one? I need common interface developer tools (lists welcome) to replace... well as many tools I have on Windows as possible.I need to be readily connected to the internet, I need OS updates to not destroy my workflow by crashing the OS, as I've seen Ubuntu do to various friends. I want efficiency, I need to be able to customise what I need to in order to perform development tasks.I guess this could be a long list, but - I don't have practical working knowledge of the Linux OS, nor how it "compares" to Windows (excuse my faux pas). I'm obviously willing to learn, but I'm far, far more keen to just... continue interface development, just on Linux instead of Windows.

I have the impression that not that many people understand the scope and limitations of GNU General Public License. This is somehow my basic understanding of it. If I take a program covered under the GNU license, first of all I have the right to get the source code. Second, I can modify it at will. Third, I can redistribute it as will too but the new code will necessarily will have the same GNU license. This made me wonder how people actually can charge for software derived from Linux, for instance, Red Hat. Well, my impression is that they really make profit only out of services. In this thread [URL] I think I found a lot of confusion, even from a moderator (not intended to offend). Red Hat is based on Linux and it is necessarily covered under GNU. Somebody probably bought the program from RHE and can make it available at no cost.
Nevertheless, the moderator decided to warn the user. In this article [URL] it says the following:"Our training is not designed to promote vendor lock-in. Though these courses are based on Red Hat Enterprise Linux, the source code for [RHEL] is available to the community via the GPL [GNU General Public License]," said Red Hat spokewoman Leigh Day. This thread [URL] shows yet more confused people. Is there is a glitch in this type of license that prevents programs like RHEL to be redistributed for free? Why their license page doesn't mention GNU license? Or the problem is just that people get overwhelmed by this license and are afraid to be penalized and get paralyzed? By the way, RHEL is just the example. The key question is about the license!!

What is the general opinion of the Mandriva and Debian distros? Mainly asking what kind of user you consider the distro to be for (beginners, advanced, total newb, whatever), and whether you think they offer as much to an extremely experienced user as they would to a newb.Those are my two favorite distros, and I really like Mandriva a lot. I'm trying to pick one to stick with throughout, but I'm not really sure if Mandriva is too automated and Windows-user oriented like Ubuntu (I haven't really delved into the deeper aspects of Linux so I have zero experience in this area now). This might sound a little elitist but I don't want to be using Mandriva and just be automatically dismissed as a newb on first impression just because I'm using Mandriva (although admittedly I am a bit of a newb at the moment, I don't plan on staying one).
