The reasoning I've always read is that it's a lot less likely to be fruitful targeting and scanning for ports on an IP which may not even refer to a live machine, so disabling ICMP response for publicly addressed servers and firewalls at least keeps them a little under the radar. I'm not as clear how much benefit you'd gain by disabling outbound ICMP traffic but I don't know jack about security.

My ISP disabled all ICMP echo on all their DNS servers which have failed multiple times. It frustrates me because I can't pinpoint the fault easily and get them to admit where the fault lies. e: I report the fault to my ISP and they have another company which manages the DNS servers. The problem lies with my ISP not being able to 'prove' the fault is this third companies fault.

Blocking PING is one thing. Blocking ICMP entirely is loving retarded. Edit - might as well add, finally signed up for the Penetrating with Backtrack class, going to take OSCP in 90 days. Yay! XakEp fucked around with this message at 02:15 on Feb 15, 2013 |

I took the CCENT last week. Missed the mark by only 4 points, but I'll definitely get it next time. I was afraid the test might have a lot of crappy questions but I actually thought the test was very fair. The print out tells you what you missed the most and I had about 88-100% in every category except for WAN's which was 20%. Easily cost me the cert. Oh well, next time is definitely a pass.

I don't know whether this has been posted or not, but here is something to fill a gap if you just need to put more certs on your resume. So apparently if you sign up for the right stuff and let the right companies know, you can get 4 certifications just for taking and passing the CompTIA Linux+ tests. Details found here. I don't know how worthwhile these certs are, but 4 is better than one, right? This trick will apparently net you the Linux+, LPIC-1, CLA, and DCTS (I can't find any official website for this one. It is apparently a Novell Data Center Technical Specialist.) NorskHotDog fucked around with this message at 06:13 on Feb 16, 2013 |

My understanding of certifications is that unless IT companies/HR are aware of the certs and value them, they aren't worth the paper they are printed on. Now who here is interested enrolling in my exclusive (and very expensive) program to earn your GOON+ certification?

Also resellers put a huge value on certifications because it qualifies them for specific levels of partnership with their vendors which means bigger discounts/margins. If you're a good engineer and you have certifications then you open up the door to make more money and you're more easily employable.

They're really not worth much without the experience to back them up, or at least complement the direction you're selling yourself. If I submit a resume with every Linux cert listed but only 6 months of callcenter helpdesk or something -- I probably expect to get treated like a paper tiger.

I know that of course, I'm working my rear end off to get the CCNA for that reason. What I meant is that is HR really going to care about certs that are basically worthless. Examples: CompTIA IT for Sales CompTIA ~cloud~ CompTIA Green IT These are just from comptia and I'm sure there many more.

Everybody would prefer experience and that's not in dispute. If someone walked into an interview with every linux cert possible and he/she did the courework legitly, I would bet that person would be a strong candidate regardless of experience.

Now who here is interested enrolling in my exclusive (and very expensive) program to earn your GOON+ certification? It really depends who you talk to, for example; I work at an IT firm, where generally partnerships require an X number of employees to hold various certifications(one of many reasons I am fixated on them) held by the company to be considered a "partner". Now you may ask, why is this important? Well different partner levels get various levels of discounted pricing on equipment, and in some cases the ability to sell X product(s). Example; if you work for a Gold Level(or highest level) Dell partner, the higher partner level you have the better discounts you get, the better discounts you get, the lower the cost of the solution you are selling; the lowest cost solution generally wins the bid to the company, resulting in more work for the company, billable hours, and more value to yourself. In government jobs they hold a different situation, paygrades, work level, and various other things. I am not too keen on it other than you'll need to fit the DoD standards, and I have worked with people who lacked knowledge on making windows images, lacked DCPROMO knowledge, and DNS skills; if that gives you a clue on how clueless people are... But I am sure someone else can give you a through overview. In private or public jobs certs can be an awesome way to stand out from someone else, or outweigh an HR who is basically googling poo poo to figure out what the department needs. My roommate was able to outweigh the person he was going against for a job due to his CCNA. Depends on the place entirely, however certs also hold another great function, benchmarking, and setting goals for yourself. Keep in mind certs are great to have passing a VCP test is awesome but understanding the material and the theory is a very good skill to have. Even if you don't know everything about everything, having a basic understanding of what needs to be done, what you need to do to get there, and last but not least, the initiative to go out and do it is a great trait to have.

Depends on the job requirements completely however here is what I think it means; System Administrator: Day to day operations of requests and operations, such as user account management, making sure servers and services are operational to end users, and maintain stability of an existing setup. Systems Engineer: Indepth knowledge of a systems administrators workload, and engineers solutions to problems that corporations have to deal with; IE we need some FTP site setup can you do it, or We need office communications. Something that requires an amount of forethought and planning in order to resolve an issue that is costing the company time and money.

three posted:It can vary, but engineers build the solution and admins manage the solution. This is my big picture take on it, too. But yeah, IT as a field is really terrible about having standardized titles. A systems engineer at one company could easily have the exact same pay and job description as a systems admin at another. You'll also likely find that at small to medium businesses, one person wears both hats. I've only worked at places with a couple dozen to a couple hundred employees, and I've always been responsible for IT projects from research to implementation to maintenance end-to-end despite my title being "system administrator". IMO the distinction only becomes relevant when you're talking large enterprises or something like a consulting firm that gathers requirements, develops a solution and then hands it off to the client for their own sysadmins to run. psydude posted:I've seen a lot of systems engineering jobs requiring programming (not just scripting) knowledge for some reason. I could see this, too. A developer role that is focused purely on internal infrastructure rather than customer-facing apps.

I asked about the value of having certs a while back, and expressed how the lack of them hasn't hurt me. Well, now that I'm looking to change that, I ran in to one small snag: Red Hat certs or LPI certs? I'm a linux sysadmin. There is little/no difference to me* for the base set of exams (through RHCE/LPIC-3). Does anyone know if there's a difference as far as HR is concerned? *I work in a mixed environment. RH/Centos5+, Ubuntu 10.04 LTS+, a few Win servers that are not my responsibility. No Debian, some BSD, we've purged solaris. Mix of Virtual and Physical hosts. While we're moving towards Ubuntu in the long run, I will most likely be changing jobs before that plan matures.

My CCENT cert expires this September so I need to get going on CCNA really. Last time I took this exam I failed by quite a distance after watching/note taking through the CBT Nuggets video series. I thought I was we'll prepped and bound for a 1000 but apparently not. What else should I be doing? I feel like I'm missing a whole chunk of information. A friend of mine told me earlier today that studying the Press eBook is essential. Is that the case? To all you CCNA's; how did you study?

One for the nitty gritty information and the other for an easy explanation and follow along.

At the time I was in Call Center hell, but during it I landed a pretty decent job in Desktop Support for a smallish company. Not the most glamorous job, but it's pretty easy and I don't wanna kill myself everyday. Having done the A+ training has definitely helped me in this job, as there's quite a few things they didn't tech me in college. Probably going after Network+ and CCNA next.

I'm using the Sybex book to study up for my A+, and I'm finding some of the little comedic interludes really great. It lightens up what could be stuffy material to some.Docter, Dulaney, and Skandier posted:Once information has been etched on a silicon chip and manufactured into the ROM package, the information couldn't be changed. If you ran out of use for the information or code on the ROM, you added little eyes and some cute fuzzy extras and you had a bug that sat on your desk and looked back at you. Any tips on figuring out what I need to truly focus on, and what I can essentially glance over? I was planning on going through this cover-to-cover, but I've found I already know a lot of this material (especially in the earlier chapters). I've been building PCs since I was a kid with my old man, know the names of components, peripherals, etc, and have some basic understanding of networking. I'm currently working on my bachelors for CS as well, and am about halfway through, but the courses have mainly had a focus in theory or programming. Pell grant money is starting to dry up, and my dead end retail job is sucking the life out of me, so I'm figuring I can knock down a few certs (A+, net+, sec+), get into an entry level position, and knock out the rest of the degree bit by bit as I can afford to do so, while gaining some experience in the field.

These will help for the A+ I pulled them out of a guide I had.  The certs alone probably won't be enough (I had great trouble finding jobs with the same certs) but that CS degree should make a difference.

With all the talk of the DBA certs in the last couple of pages, were there any recommended books or study guides that people have used? I'm a linux sysadmin but my company threw me access to the oracle online training course MySQL for DBA's. Manager is pushing for me to get certified to help make a case for my promotion/raise, even though I don't really work with db's at all I suppose it will look fancy. The Oracle Certified Professional for MySQL admins looks to be what I want to take, and also seems like the associate cert isn't required? Is that correct? Anyone else taken the 1Z0-873 and 1Z0-874?
