    For desktop stuff, I have a solution to that: I have a small plywood shelf unit (think: post office mailbox sized shelves/boxes). Devices sit inside the box. Cables are threaded in through the back of the box, and excess length gets cinch tied into the box with the adapter plug. Right now I've got a 6x5 cubby cube, about 1.5'x2' in size. The power for the unit is on a surge protector bar, which is screwed into the wall above it. Excess cord (if there is any) dangles behind the desk in a natural loop. (I've also used cinch ties to make sure that power bricks hanging this way do not lose the power cord from their rear.)

    As for networking:
    Get 5 different cable colors and then each bundle needs to have no more than 5 cables. You then take those bundles of 5, which are small enough and convenient enough to neatly bundle or wrap in and of themselves, and bundle them together

    Typically, I've found, you need 1 to 3 bundles per rack. Any extra runs can just hide or dangle free; it's still less mess. (If you're doing central switching instead of the more preferable top of rack switching, it's a bit of a pain in the ass. ) These bundles then get labeled - with a simple number. I can quickly figure out where something is plugged in by looking for that bundle on the switch and the appropriate color.

    I prefer to do my bundling exclusively with Velcro but quick ties work pretty well at the 'switch side' of the cable to keep everything tight and neat, too.

    (Or do bundles of 8 or something like that with 8 colors, whatever. 5 works out pretty well with pre-existing cables sometimes, too, though - red, blue, green, grey, black).

    You do realize that 'administering' FreeNAS isn't the same as administering Samba, right? Just checking.

    (I have found that the likelihood of issues with file sharing/whatever with Samba is fairly highly related to how well the 'integration' was handled beforehand by the distribution/packager, as is the case in FreeNAS. They polished that aspect very nicely.)

  8. Re:No on Ask Slashdot: Is Samba4 a Viable Alternative To Active Directory? · · Score: 5, Interesting

    You realize that the guide you link is not only horribly out of date (over a year IIRC since alpha11 came out) and won't work with any of the current alpha (yeah, ALPHA) releases, but that Samba 4 has it's own dNS server now, basically requiring it operate autonomously from existing infrastructure?

    Yes, building/installing and then provisioning Samba 4 takes all of about 5 minutes. Now integrate it with something which was in existence before you decide to stroke your balls with Samba 4... good luck, let me know how it goes.

  9. Please consider a couple things: of all the Linux/Unix daemons I've had to administer, Samba is by far the most cumbersome and finicky, requiring the most attention regardless of distribution.

    * It's usually not possible to run Debian's Samba(3) packages without pulling the backports. They won't work with anything remotely recent, more than likely.
    * I've had several situations where upgrades on 'stable' releases of Linux have resulted in Samba bugs manifesting (twice resulting in an unplanned outage, personally). Regressions? Who knows. They're frequent enough that I can think of 3-4 that've occurred in the last couple years.
    * This may be more the fault of ports, but I've had the samba FreeBSD ports distribution break configuration compatibility multiple times in just the past two years (using AD domain based authentication). My understanding is that Ports is fairly 'consistent' with upstream and this is suggestive of release problems upstream.

    Also, samba is not 'consistently reliable'. Is it consistently stable? Very much so. However, I'd rather read slapd logs than samba logs; they're a fucking pit of vipers, and you'll end up learning more about SMB, CIFS, winbind, etc. protocols trying to figure out what's going on than your average high-quality Windows admin (you know, the ones with the high end certs) could even begin to understand. The unfortunate fact is, reading the logs for samba has always been fairly necessary, with a relatively high log verbosity; this doesn't bode well for reliability. ;) And this doesn't even delve into the problems encountered due to MS-pushed patching or eg. talking with poorly behaving Macs running old versions of Samba: truth be told, it doesn't seem to interoperate with itself all that well.

    As a basic file and print service it does quite well, particularly on the CUPS print interchange role. But IMO it hasn't been a 'superior' file serving platform to Windows since 2008 came out. It's functionality is "marginal" unless you've got people willing and able to set up LDAP and backend it against that, or want to use Windows domain credentialing. (Even then, the ACLs can get a bit fubar.)

  10. Re:No on Ask Slashdot: Is Samba4 a Viable Alternative To Active Directory? · · Score: 4, Interesting

    Sorry, what? Have you run Samba in a business environment? I have, and I can completely understand the sentiments here: there's a lot of little stuff that goes amiss or requires seemingly excessive management.

    There are a LOT of "small glitches" while using Samba 3 in any not-just-Linux environment. It has nothing to do with 'poor administration'. Over the years, I have had problems with Windows - 98, XP, 2k, 2k3,Vista, and now W7 - operating properly against a Samba host. This isn't a matter of 'improperly administered' so much as it's a "Microsoft released a patch which broke things which worked previously" problem, and it seems to be getting worse as time goes on.

    To add insult to injury, Samba 3 development has basically been in 'maintenance' mode for years, with Samba 4 getting seemingly preferential treatment. There have been very few new features of functionality added to Samba 3 aside from the odd "needed to keep things working well" patch or a backport from Samba 4 by an intrepid sysadmin (or so it seems). Really, what used to seem like a very nice and mature project now feels like something on life support, with half the features present having been backported from the development branch, often without a full implementation, inconsistencies, and no/poor documentation.

    As for Samba 4, (which neither you nor my post's GP seem to realize we're talking about here): it's an entirely different beast than Samba 3. The only significant thing it appears to share in common with Samba 3 is the smb.conf format and actual file/print services (which is a fairly recent change). It is still in HEAVY development. What they started out to implement was really quite awesome and interesting: Active Directory based on open source tools currently in existence. At one point, they were using BIND for DNS integration and Heimdal for the directory. Their team members made many valiant attempts and efforts in providing patches to these supporting projects.

    However...

    Both those things are now internal to Samba 4. That's right: the directory itself as well as a DNS server are components to Samba 4. IMO, this is the biggest mistake they've made, and waiting would've been worth it if they could've gotten BIND to work (they couldn't, due to design differences between it and Windows AD/DNS frequency, chain of authority, etc. IIRC - not without making a mess).

    Integration of their own directory (based on a heimdal fork, IIRC) makes sense. But not DNS, at least as its implemented now. The DNS server is not BIND compatible and will not take a zone transfer, and doesn't even do reverse records yet (not properly, at least).

    THAT SAID, Samba 4 is still not hitting a 1.0 release. Who knows if 1.0 will mean 'beta, we're polishing' or 'production ready' - but I will bet you anything that it will be lacking documentation on how the tools work and have quite a few bugs. :(

    I've been a follower of Samba 4 since I was in college, and that was close to a decade ago. I don't think there's much hope of it ever being production ready, not anymore. They tried to do too much, and as a result, Samba 4 won't be all that usable in an existing Samba 3 network where DNS is also used - it just won't be possible without making a huge mess of things due to a pre-existing DNS system which won't be able to be fully compatible.

    Samba 4 works "OK" at home, but only if you've got very limited needs and you're starting from scratch. It's not nearly as flexible as Samba 3 (eg. different authentication backends, for instance) and from my point of view will not be 'production ready' for many years at its current pace.

    * it's well known that pole ice pack has actually increased in depth over the last several years.
