I am really really bad at remembering ports for anything other than the simplest things (like, SSH = 22), so yeah, I'd be really awful at that.  e) i also remember TFTP = 69 because that's a funny number

Am I the guy who replies twice in a row? Yes I am. People who remember ports are the worst people. There are some legitimate ports to remember, either because they are so unbearably common (80, 443) that you'd have to have your head in the sand to forget. Others are important because you're going to need to know the port the 4th and 5th times you beg your network admin to lighten up and open 1433 or 3389 for god's sake. But others, like DNS being 53, or LDAP being 636? Feh, there's more important things to know. Like right now, I know I've heard it but I can't remember what port DHCP uses. And I don't care, and I would appreciate if the entire internet would help me out by never telling me the port, because I'm pretty okay with having forgotten it. If I need it, google's right there.

Tab8715 posted:Original Question Sepist's question is entirely reasonable, especially if they're looking to hire CCNP-level folks. The original original question was "You make a request to website, what happens?" and then they lamented that people messed up the MAC addresses involved, which is weird since I wouldn't really think to talk about frame encapsulation there, I would focus more on DNS and routing. EDIT: That explanation makes it more reasonable. Inspector_666 fucked around with this message at 21:34 on May 13, 2014 |

I'm trying really really hard to avoid call center hell for my first IT-related job. I've gotten a few calls back and a couple interviews, so fingers crossed. I think despite having little experience I give off an air of being at least somewhat competent in person and I should have a CCENT within a few weeks and a CCNA around 5-ish weeks after that. Hopefully my desirability will go up after that. Still,  at nearly every "entry level" job I find being "3+ years at random technology."

The most promising interview I've had so far came from Craigslist actually. I've been using Indeed, Glassdoor, DICE, CNMConnect (which does nonprofit job posting), USAJobs, GovermentJobs, Craigslist, and various local universities. I'd really like to work in the IT dept for a university I think. Its just the job posting really that mentions how much experience is required. Sickening posted:Skipping the helldesk is not an impossible task and is more than worth the hell you will put through to find something else. Do you have a college degree at least? I have a B.S. in Poli Sci/History (don't ask, its dumb), and I'm currently finishing up a B.S. in IT. I think I'll be done by December at the rate I'm going.

Eonwe posted:I'm working toward my CCENT and I'm not looking forward to subnetting. Predicting the MAC addresses seems like it will be a fairly easy part of the exam. I was feeling nervous about getting my CCNA in general until I learned about the show CDP neighbors detail command. Yeah, subnetting is the thing that gets most people angry on the CCENT, and there's no shortcut to it, you really just have to learn it. What I find funny is people who complain about subnetting, then complain even more about IPv6 being on the exam, when pretty much everything (including subnetting) about IPv6 except actually reading the addresses is a hundred times easier than IPv4

lampey posted:I should have added some details, the whole problem is drawn out on a whiteboard. It is an exercise to understand tcp/ip networking. Its more about how they solve the different parts. I e this is a new computer, the network config shows ... a web browser returns a 403 error, ... ipconfig shows media disconnected. A lot of people got the source port (random high number) wrong and the destination mac will be the fw/ gateway. Technically the source port will change due to nat when going out, but it will get changed back on the return. This is for an intern position? Is it paid?

They meant to click comicbookpodcast.mp3, hit comicbookpodcast.torrent instead. Within minutes, pretty much all internet stuff stopped working. Obviously bittorrent had downloaded viruses onto the network. Long story short, someone decided that port 80 was "the Bittorrent Port" and blocked it.

Yeah I remember someone posting that a month or two back from a practice test. I think the problem they were trying to highlight was that the client and server were in different subnets and there was no router in between so it was impossible for them to ever communicate. But they described the failure as "the server returns 404 Not Found" which is impossible because the request would never even reach it.

NippleFloss posted:If someone has a CCNA and can't answer a basic question about addressing behavior at layer 2 and layer 3 then I would question their learning ability because that is covered to death on the test, and their ability to pass the test but not actually know a major portion of the material would be a pretty big red flag. That's why I said "basics." They don't need to know how addressing schemes are set up and translated for web applications in a load-balaced datacenter.

CLAM DOWN posted:Does anyone else here have to deal with Blackberry enterprise support? I want to put a gun in my mouth. I spent ~15 hours over two weeks troubleshooting a BES console server that wouldn't patch. I figure about half that time was chasing down vague red herrings from their escalation team. I also enjoyed answering the same question 3 times over two days of slow email responses. Wound up learning to read their install log better than they did, found the fix, and gave them a detailed report on it. They're pleased with my work and promised to write up a KB article for it. The only thing the support contract is good for is to CYA when poo poo hits the fan and VIPs want answers.

No one else was talking about load balancers or NAT though. Just a basic question about layer 2 and 3 addressing. That said, no matter how many intervening devices there are if someone whiteboards the traffic flow I'd expect any level of network admin to tell me the source and destination Mac at each hop.

Had a really good interview in an office environment that seems like the exact opposite of where I am now. It was weird to see people excited about marketing software when I work for a company who's product literally saves lives and no one gives a poo poo. If anything we would all probably feel best if they burned to the ground, mostly for the irony.

Thanks to everyone who gave me feedback on working in healthcare IT. I had an interview for a Clinical Informatics Analyst position today, think I nailed it. Felt good to get out of scrubs and wear a suit again. I'm excited to get away from the sick and dying, and start walking around in business casual, drinking coffee and telling nurses to reboot their computer.
