Apple Still Has Not Patched the DNS Hole

Steve Shockley notes an article up at TidBITS on Apple's unexplained failure to patch the DNS vulnerability that we have been discussing for a few weeks now. "Apple uses the popular Internet Systems Consortium BIND DNS server, which was one of the first tools patched, but Apple has yet to include the fixed version in Mac OS X Server, despite being notified of vulnerability details early in the process and being informed of the coordinated patch release date."

      Hmm ... I don't think I'd recommend a Mac OSX machine for a server, especially to a small site without technical expertise. When I tried this a couple of years ago, it took me the longest time to figure out why not only that machine, but also a lot of machines in the neighborhood, were so flakey.

      One of the issues was the "Internet Sharing" buzz phrase. If you google that now, you'll find lots of warnings that if you enable this in OSX, it silently starts up a DHCP server. If there's already a DNCP server anywhere on the local network, you now have two of them battling it out, and the symptoms aren't something I'd wish on anyone but a networking expert. Apple's CS people were supremely unhelpful, too. They just made it clear that my problem was that we were running non-Apple equipment on the network, and we would have to shut them off before they could diagnose the problem. Yeah, right. I shut the OSX box off instead, and then started learning what it took to explain why that fixed the other machines' problems. If you're a novice, you really don't need a rogue DHCP server on your network. When the other users figure out that it's on your machine, they will not be very friendly.

      I've also experimented with an OSX web server. The main problem here is that OSX does funky things with file names, starting with their "caseless" feature. This works if everything was developed on OSX. But if you're running a web server, you're probably going to be including things from other machines in the vicinity. If they're not OSX, you'll go crazy trying to figure out what's going on with the file names. And you probably won't be able to fix it.

      The conventional answer you get from the OSX folks is to run the HFS+ file system, which supports case. Well, I tried that. It turns out you have to reformat the disk for HFS+; you can't just flip a bit to turn HFS into HFS+. I did that, and reloaded from backup. Then a couple months later, we had some problems with the disk. I sent it off to Apple for diagnosis, and it came back apparently fixed. Actually, they had replaced it with a new disk, and they copied all our files over. It was formatted as HFS. Oooops! This happened a couple of times with other Macs, so it seems to be a systemic problem. Pointing out to them that you're using HFS+ has no effect.

      And even with HFS+, there are some funky file naming problems that I don't understand. I saw a lot of cases where an rsync would produce strange file names on just the OSX system. Linux, Solaris, *BSD systems, and usually even Windows could rsync back and forth, and they'd end up with the same file names (though Windows would proceed to ignore case and get the wrong files at times). But on OSX, we'd see non-ASCII chars simply garbaged with no obvious pattern.

      So unless you know that you'll never want to copy directories full of files from a non-OSX machine, I'd advise against using OSX as a serious server. It won't work, and Apple's people won't cooperate with diagnosing the problems. (And you'll just get insults if you mention it here on /. ;-). Save yourself the headaches and wasted weekends, and build a server with a real unix-type file system that accepts any bit patterns except '/' and NUL in file names without damaging them.

      (And I have occasionally wished that I could use '/' and NUL in file names. I wonder if there's a system that allows all 256 8-bit bytes in a file name... ;-)

      (And I wonder if there are linux systems that do "intelligent" things with file names. If so, should we also be warning people to avoid them as servers?)

      OK. I'll start from the beginning.

      All the 'internet sharing' devices and operating systems (including Windows XP) will fire up a DHCP server on the LAN they're sharing to, that's what internet sharing is, a single device acting as a NAT/RIP gateway for several other machines. DHCP is quite a simple service (too simple if you ask me, given this particular problem), if you -sometimes- get IPs and other times do not, there's probably a contending DHCP server on your LAN that needs to be hunted down and killed. This is netwoking 101. You never plug the 'LAN' side of a NAT device into a LAN that already has a DHCP server, unless you're sure you know what you're doing.

      Second, regarding the 'case issues'. There is a case sensitive option (that you -can- flip arbitrarily) in HFS+. There are -case issues- if you're doing some kinds of things (CVS checkouts of source directories with colliding names, etc.), but generally nothing that a little understanding wouldn't fix.

      Why on -earth- you would use HFS at all instead of HFS+ is beyond me. That's trying to install Windows on a FAT16 disk. HFS+ has its strong and weak points, but HFS is a dead -dead- dinosaur.

      It really sounds like your mac experiences were from the early 10.x days or even the Classic Times of Olde. I've admin'd several OS X (10.3 - 10.5) servers that do printing, file sharing, VPN, directory services, desktop management, web serving, and even Windows Domain Control, and I've never had a problem with anything you're talking about.

      As of today, we've extricated ourselves from the hell that was Xserves. We purchased a number of these machines because it seemed like an easy and cheap way to get a fileserver going that did both AFP and SMB, was AD-integrated, and could have its file store on a SAN. Well, after much money and a year later, the answer is that Apple very much oversold their ability to integrate into a Windows environment. Here are my gripes:
      • AD-binding is not straightforward. Apple really wants you to run an OpenDirectory, as this allows you to both manage Apple desktops and do single-sign on. If you just want to allow AD authentication on your MacOS X servers, good luck. You're in for a bugfest, with partially-working GUIs and many, many quirks.
      • #1 quirk being: you can't do cross-domain authentication, even if those domains are trusted. This was a showstopper for us.
      • There is only ONE backup application for Xsan that is both a) reliable, and b) has a reasonable support contract. We tried Retrospect (total POS), Veritas (ridiculous wait times for support), and finally, BRU. BRU has a decent product, but the number of MacOS bugs that plague this application make it unreliable and frustrating to use. OSS applications don't handle the numerous HFS+ corner cases. Rsync, which we used for snapshots, routinely hemorrhaged itself on files with extended attributes, despite the fact that this was APPLE'S OWN VERSION.
      • Ever try running a shared AFP/SMB volume on an Xsan? You can't. Surprise, surprise: Xsan is not HFS+ formatted. It uses CVFS, which is a Quantum/ADIC filesystem. Why? Because Xsan is simply a rebadged version of StorNext! So your AFP daemon will spew Mac metadata everywhere which your SMB daemon will not honor, thus totally corrupting your data. Fuck you, Apple. Seriously.
      • You can't modify MacOS X Server files on the command line. Oh, well, you could on 10.4 server; then lock the file and hope you never had to use the GUI again. But on 10.5, even that does not work-- it still overwrites your file; smb.conf is a perfect example. I figured, OK, maybe I should set the immutable flag, but then I started thinking... WHY am I using Apple products again?
      • Apple's enterprise support blows. Sometimes you get an answer, but no matter what, expect a long wait while people on the other end decide whether they want to bother answering your question or not. Want to follow-up on a bug that someone else reported? Good luck. Their bug reporter is terrible. Would it be so hard to run Bugzilla?

      Apple needs to get their shit together. Unless your needs are VERY straightforward, even 10.5 does not solve them. I'll admit that 10.5 has a much nicer server admin GUI, but it does not overcome the problems with the platform.

      We've moved all of these services to CentOS machines. By contrast, getting them working reliably was a walk in the park. Equivalent hardware (hotswap RAID (SCSI, I should add), redundant PSU, fiber channel card, GigE, dual processor machines in a 3U form factor (SuperMicro chassis) come out to about $1k less than an Xserve, on average. And when a part dies, like a backplane, I can BUY THAT PART. With Apple, you have to buy an entire parts kit, which comes with stuff you may not want.

      We now run Samba and Netatalk on CentOS on generic server hardware, connected to our StorNext network. There may be better SAN stuff out there than StorNext (in fact, their licensing department leaves much to be desired-- do they even know how to use their own product?), but we already had a lot invested (three Xserve RAID cabinets). Things run great now, and with the Linux version of BRU, our full tape backup [inexplicably] finishes 9 hours earlier (used to take 60 hours, now takes 51).

      My advice: Apple makes some nice desktops, but their server stuff is only for novices. I went into the experience very optimistic about Apple's stuff, but now I have a very bitter taste in my mouth.
