FUDCon Friend Finders

On the FUDCon 2011 Wiki page, suggested optional equipment is a Fedora Friend Finder (here’s my archive, since as of 2020 the link has long since been abandoned and bought by someone else), which is an extension cord with multiple sockets. I brought one, which has a 30′ extension cord, and it has typically had 2 to 3 plugs, including my own. Right now, I’m in the Lightning Talks, and I’m impressed: My FFF is plugged into another full FFF, and mine is full. Further, I’ve had two plug-in requests to which I’ve had to say, “sorry, I’m filled up”.

Now, I’m just looking for my profits. 🙂

On another note, today I went to get an extra-large pizza at Slice’s Pizzeria around the corner. I made friends quick. 🙂 One person who joined us after the pizza ran out was a local community college professor who saw my security presentation yesterday, and enjoyed it. So much so that he asked if I’d grant permission for him to use it in one of his classes, which I happily granted.

FUDCon 2011 — after my presentation

So I’ve just given my presentation at FUDCon on some basic security strategies to install on your system.

People seemed receptive. A couple of the ideas that came up was the use of denyhosts before I mentioned it, and a bit of controversy over the root user. People were suggesting the use of keys instead of passwords for the root user, and using sudo instead of allowing direct access to root.

The pairing with someone else worked ok for me — I started at 14:30 and got through all my slides in 20 minutes, including a few questions and comments; I did have to go a mile a minute though. The other person, who did an exposé on the Fedora Security Labs spin, however, had to skip a few of the things he wanted to do and talk about. His presentation was nonetheless interesting.

As I said people were generally receptive and respectful, and people generally recognized that my presentation covers basic security that anyone and everyone should do, and that it’s not necessarily intended to cover all cases or massive networks.

FUDCon 2011

Here I am at FUDCon in Tempe, Arizona.

First off, on a side note, I knew that Arizona was warm. But I left late January and came to early September. I’m blown away that I don’t even need a light jacket let alone a parka. This is the kind of weather that would be nice all year long, but I hear that Phoenix is a bit too warm, certainly for me, in the summer … 🙂

Currently I’m in a Fedora Board Meeting or whatever where things along the line of discussing the future of Fedora and how people can get more involved. Jared, the current Fedora leader, has 15 “short list” goals up on the screen, basically discussing general lines of how people can contribute and how the project can get the right people to the right job, as well as “how to get there”.

This morning I attended a talk given by an anthropologist who studied the Fedora community, such as through a previous FUDCon, and discussed her findings and how people were involved, why, and all sorts of interesting stats.

During the next session I’ll be giving my presentation on Strategies to Secure a linux system, but given the number of talks, the BarCamp style voting, and the available time & rooms, I’ve been paired with another presenter who will be discussing general security practices; his presentation is supposed to be general in nature, while mine is technical and a specific list of things to do, so perhaps this will work out nicely since he’ll presumably talk about “you should allow this and disallow that” while I discuss “go here and do this, and here are the menus to click or the command line how”. The person seems quite nice and we’ve agreed to speed up our presentation speeds and divide the time more or less equally amongst ourselves.

To be followed.

FUDCon 2011: Almost here!

So I’m quite excited about my upcoming attendance at FUDCon.

I also have some (sort of, depending on your perspective) answers to my questions, gleaned from a couple of discussions on IRC:

– People are available on IRC — Freenode at #fedora-fudcon. However, over the past week it has seemed quiet, but people are there and do answer questions and will chat.
– A list of the available restaurants was provided to me. It includes restaurants, take out (I’ve heard of Five Guys, Burgers and Fries, I’ll have to try them out), delivery places (heavy on pizza — let’s hope they can make it right, pizza outside of Quebec is a strange beast, even the good stuff), and at least one brewpub, which is in walking distance of the conference. The list will be provided in the information package given out to everyone upon registration/check in. Which means that, as I pretty much expected, people are on their own for food the whole time, just as I will be during the rest of my vacation in the area. Nice to know, though. Hopefully any further information different from that will be communicated, as I’m sure it will be.
– Yes, a projector will be available.
– And for the fun part, the presentations will be judged/refereed along the lines of “On Saturday morning, there will be sign up sheets for the various presentations. Those with the fewest sign-ups will be dropped or combined with other similar presentations according to the number of presentations and the available space.”

Also, I still have to figure out how to either not freeze on the way to the airport in Montreal, and then back home, or not boil to death with my parka when I arrive in Phoenix. Around here in Montreal this time of the year, “warm” is about -10C to -25C, without the wind chill. Phoenix area, “cool” is around +4C; “warm” is about +17C. Sheesh, to me that sounds like mid to late September, not late January. 🙂

FUDCon, Tempe, Phoenix, and the Grand Canyon, watch out, here I come. I’m a LUzer bay-bai, so why don’t you flame me? 🙂

FUDCon 2011 — Tempe, Arizona

Well, here I am, I finally did it. I’m going to FUDCon 2011 in Tempe, Arizona.

After months of saying to myself and friends “Oh I think I’d like to go do this” and asking my brother if he’s interested, and telling all sorts of people “Yep I’m doing it, I’m thinking about doing it, I’m still in the talking about it stage; I just haven’t committed to it yet”, I bought my airline tickets a couple of weeks ago to go to Phoenix, Arizona, and made reservations at the hotel. (Yes, the nice people at the hotel, months after the block was “closed”, graciously gave me the Red Hat Group rate for 6 out of 7 nights — quite the savings!)

So I’ve been working for the past few weeks at translating, updating, revising, rationalizing, etc. a presentation on System Security I presented at my local LUG a couple of years ago. (Of course it’s not in English, silly, why do you think I’ve had to work on translating it?) I’ve also been following the wiki page for the event (here’s my archive of the page).  I even have my Fedora Friend Finder (here’s my archive of the page, since the webpage disappeared) ready to bring with me.

But … apart from a few blog posts here and there, and of course the availability of the administrative notices / minutes from the planning meetings, I haven’t found what appears to be, let’s say, an online forum where FUDCon is being discussed. (Yes, I know, there’s Planet Fedora — however, it seems to discuss pretty much everything under the Red Hat sun.) The kind of place where people discuss what they’re doing outside of the formal event structure, when they’re arriving, asking questions of participants of previous such events, and so on. Basically, chatter.

I’m wondering a few things, and hope that perhaps this post will help me out in at least finding a nudge in the right direction:

– Is there a forum where people are virtually gathering and discussing the plans and attendance and logistics and so on surrounding going to FUDCon? You know, chatter?
– Assuming that my presentation isn’t tossed for being too long, too technical, too boring, out in left field, or targeted to the wrong audience (it’s sysadmin stuff, not development), will there be a projector available? Will I need my laptop — which I’ll of course have anyway — or just a USB memory stick with the presentation on it? (OO.o format, or PDF? Of course I’ll be ready for all of these circumstances.)
– Regarding my presentation, will someone be wanting it to be submitted in advance for the part about “Refereeing for technical sessions”? Or will “in advance”, in keeping with the “so do not worry about competition” part, mean half an hour before the “Orientation, BarCamp pitches and scheduling” at 9:00am Saturday?
– I signed up after the 140 cut-off mark for food and swag. I don’t have a problem with the basic concept per se: you snooze, you lose, you should have signed up earlier. However, I’m just wondering what the real implications to this are — to what food is being referred? Breakfast, lunch, and supper throughout all the event? Snacks in the hospitality suite — no green stamp on your name tag, no food? A few chits for free meals, given to the first 140 people, at the Student Union cafeteria where a lot of people presumably will eat during the breaks? Food during the FUDPub, at which Red Hat “will be treating everyone to food”? (Or just the first 140 — everyone else with a differently-marked name tag will have to pull out their wallets?) I’m just trying to figure out logistics, that’s all; I’m trying to find the ad for the advertised food, so that I know what’s being discussed. Money isn’t the issue; I’m just looking for some kind of indication, that’s all.

Well, that’s off my chest.

In other directions, I guess I now have to prepare my laptop for going through customs:
– set up an automatic login (a warning against which is in my presentation);
– do a bit of a system cleanup (a suggestion about which is in my presentation);
– remove some privileged information and make sure that it’s really wiped;
– realize that US Customs probably won’t care about my computer, and that the only people who might will be the airline — and hopefully only be amused at the XRay area when they see the square, plastic bucket I carry it in (but hopefully not say that’s it’s oversized, which it shouldn’t be. The primary airline’s limits are 23 cm x 40 cm x 55 cm; the secondary airline’s limits are 23cm x 35cm x 56 cm. I’ve just checked, and it fits.)

Oreo uses linux?

There’s an Oreo commercial with a father and son eating Oreo cookies together at son’s bedtime via the internet while Dad is on a business trip somewhere it’s morning already. I’ve seen this commercial a few times over the past I don’t know how long.

A quick glimpse at the boy’s laptop screen makes me wonder for the umpteenth time — is that a Gnome desktop with a Fedora blue?

Obviously as usual it’s a quick, oblique view of a screen whose resolution is just fuzzy enough that it’s hard to tell. The basis of my hope is, as stated, the Fedora blue background, plus the white taskbar at the top of the screen and what appears to be the Gnome menus.

Anyway, yet another entry in the “I hope I’m not disappointed again but it probably isn’t linux use” in commercials game.

I’m going virtual, and hitting a real brick wall

This week after reading the June 2010 issue of Linux Format I decided to do what the cover article was about, which was “Try any Distro!” “Luckily enough” I use the base distro that they recommend, Fedora, “because it has the best implementation of Virt-Manager”.

Certainly the setup of Virt Manager was easy (yum install kvm virt-manager libvirt). And the next part was as easy: I downloaded the PC-BSD net install ISO. PC-BSD because I’ve been wanting to try BSD for a while, and PC-BSD because the same issue of Linux Format happened to review it.

After that things went well: I follow the setup — 10 gigs virtual hard drive, “1” processor of two (my machine only has one, but I guess the hyperthreading is up and running, so the system identifies two processors) 512 megs of ram, etc. And I go through the easy setup. The whole things takes about 3 hours to download all the packages and do the setup. Bedtime comes around, and it’s ready to reboot. Darn, I have to go to bed on an error message: “No /boot/kernel/kernel”.

So the next evening, I decide to try OpenSolaris and OpenSuSE, the latter in the netinstall option. Things fare worse: OpenSolaris says that there’s “No bootable device”. Huh? Isn’t it supposed to boot off of the ISO so that I can go through either the install process or see the live-CD? OpenSuSE gives me the same result.

I’ll have to look into this … the second two experiences make me wonder if the PC-BSD problem is not coincidence, but I think that it coincidentally tells me that there is a problem with reading the virtual hard drives, but the problem with the second and third cases is just getting them to properly boot the ISOs …

Ubuntu and Fedora LiveCDs — Ubuntu a clear winner!

I’m trying to convince a certain group to wipe their virus infected (and no doubt with trojan horses, key loggers, and spyware) computer over to linux, and so I’ve burned the Fedora 12 Live CD and the Ubuntu 9.10 Live CD.

I don’t want to bother giving them the Fedora Live CD. The Ubuntu CD is far too slick. And, the Fedora Live CD is far too vanilla. And that’s despite my usual rivalry with Ubuntu; at first glance, the killer is the inclusion of OpenOffice.org on the Ubuntu CD, while Fedora has the lightweight (albeit otherwise capable) AbiWord. Even the brown looks bright and welcoming, as opposed to Fedora’s more conservative, dull greyish-blue.

Add to that the directory of various files introducing Ubuntu, what it’s about, and even a sample mortgage calculator, and it’s little wonder that Ubuntu gets a whole lot of first timers straight out of the gate, or that first timers settle on Ubuntu after trying a bunch of other distros. As a marketing tool (at least for the desktop), the Ubuntu CD wins hands down; I’m not even sure that fully set up via traditional means from the DVD or full set of CD’s Fedora is this flashy.

I’ve been telling people for a while that “I use Fedora, but you’ll find Ubuntu easier”. I’ve just seen the proof. Seeing the CD, I would want to start afresh with it. I won’t of course, but I was impressed.

I’m wondering, though, which is the real killer — the inclusion of OpenOffice.org, or the directory introducing Ubuntu? I bet that were Fedora to mount a similar directory, including how to expand upon the base supplied on the CD, that people might take it up a bit more. I’m thinking of things like “Accustomed to OpenOffice.org? Go here and this is what you do.” or a “top five” “what to do once you install the Fedora base (or even just the Live-CD)” based on “Common desktop tasks”, “Setting up a home file and media server”, or the usual choices found in the standard anaconda setup.

I’m even thinking that the Ubuntu Live CD is productive — and “complete” — right away with its little directory, forget having little tutorials.

I guess that I should find out about whether or not Fedora does something like this, though … 🙂

It’s tax time, and the Government of Canada supports linux!

Doing a bit of research for tax-time, I went to Service Canada’s website to get some extra information needed. I finally figured out how to navigate through some pages, and whaddya know, they support two linux distributions: Fedora (they added, incorrectly, “Core”) 8 — which of course now is out of date — and Ubuntu 7.1, which I suppose was really 7.10. I suppose to some government person who doesn’t quite understand Ubuntu’s version numbering system, 7.1 and 7.10 are “about the same” — of course, were there any validity at all, it would represent the January 2007 release of Ubuntu, which never existed, as opposed to the October 2007 release. 🙂

I was pleased to see them finally picking up the slack, even if this was put in place about 2 years ago. 🙂

And of course, here’s the screenshot, with the appropriate areas highlighted.

19 months, 16 *successful* installs

I just did a tally of all the installs I’ve done on my personal systems since the end of June, 2008, when I bought a new-to-me desktop and took advantage of the opportunity to upgrade from the CentOS 4.x series (to the CentOS 5.x series. 🙂 ). And I was a bit blown over; unfortunately, not surprised, but blown over nonetheless.

Over 5 systems, I’ve done 16 successful installs; then there were a few dud installs that had to be restarted right away, although a couple of said duds were counted because the installs were actually useful for a few weeks, including one not counted as a successful install during the most recent cycle despite the fact that it was a successful install; unfortunately, the boot sector on the drive died (it was to be expected, back last June or July, Palimptest identified the drive as having a fatal error on it, and the drive was declared as having about 6 months to live, and whaddya know!) so I had to get another “new” drive, which I happened to have handy, and do another install.

To be fair, there has been one factory sealed new system thrown in there (what fun to wipe the Windows install, which curiously, apparently irreparably froze up after all the updates were done, the whole thing to be able to say “yeah, but Windows worked on it!” — which it didn’t!), another system that just about hasn’t been used since and after a few months has now been removed from the upgrade cycle, another system that finally died or at least on whose ghost I have given up, and a finally a replacement system for said “death in the family”.

One of the reasons why I always say “I’d love to go back to CentOS if it weren’t so hopelessly obsolete” is that it’s stable and has a long life to it (something like typically 7 years) — Fedora *has* been good to me since I started using it from version 9, and hence with CentOS you don’t have to upgrade every six months like with Fedora — oops, that’s every 12 months or so — given the support cycle (wink wink). 🙂

Problem is that when you have several systems, you’re still doing installs every 6 months or so if the systems aren’t in sync with each other; further one of the consequences of using second hand or third hand computers, buying new computers, upgrading parts and hard drives, and even trying out another distro at least once is that your systems are hardly every likely to be in sync for the whole 13 months or so lifespan of a new-version-released-every-6-months distro like Fedora. And of course, that someone who would like to avoid having to do new installs every 6 months is going to upgrade a system that is out of sync to bring it in line with the others in the hopes that “this will be the cycle when I get to enjoy the whole lifespan and not have to upgrade 6 months from now”.

Hence the ideal of trying to avoid the “install every 6 month habit” by syncing the installs with each other when a single new install is done in order to hopefully avoid having to reinstall in 6 months is fallacious when you have at least two systems — in fact, you end up doing the opposite since you not only are installing (or re-installing) at least once every six months for one legitimate reason or another, but you end up doing multiple installs, many of which are unnecessary in and of themselves, every 6 months, just to keep everything in sync. And as such, the “install every 6 month habit”.

Of course, I have often been enjoying the process despite myself; in fact, I’ve managed to put together an ever-increasingly long list of steps to take from start to finish when installing a system (which I’ll be presenting to one of the local LUGs in a few weeks.) Fortunately, my computers are purely home desktops or hobby servers without any critical processes on them, and my brother at least humours my habit by doing those little bits that are still beyond my ever-increasing sysadmin skill set (which of course is growing with each install cycle). And in the process I’m gaining a practical appreciation for what I’ve known all along since I started using Linux in 2006 and started using CentOS: The likes of Fedora and Ubuntu may be great, but you have to re-install every 6 months! Who wants to do that?!?!” (Apparently, I do. 🙂 )

It must be interesting having multiple production servers with multiple versions of a given distro, let alone more than one distro (ie. a mix of CentOS, Debian, SuSE, and for some good fun, Slackware). Good thing that usually having “the latest and greatest” usually isn’t as particularly important on a server so that it can actually have a useful life. Must be hard for the likes of Red Hat, for instance, when it must add new drivers all the time, but in order to keep from breaking compatibility and adding “bad change” into the distro other things don’t happen (things like the HPLIP version that is one incremental subversion or whatever it 0.x increments are called behind the minimum requirements for my 2.5 year old printer, and which has since gone through several such incremental upgrades and at least a whole version upgrade since.)
