Served: the Mac OS X Lion Server review

Posted by steve on Jan 16, 2012 in internet, network, Reviews, Software Reviews

I’ve been running Mac OS X Server in various incarnations for about six years. I’m reluctant to be terribly specific, since I don’t remember with a good deal of precision when I first installed Apple’s server operating system on the old eMac that I’d repurposed for my daughter’s use, Debbie having finally upgraded to a PowerMac G5.

Most recently I’ve had Mac OS X 10.6 Snow Leopard Server (a clunkily-named piece of software, to be sure, but then Apple are not know for their elegance in nomenclature), running on a headless Mac mini, a system I wrote about a handful of years ago and which Apple clearly used as inspiration for their min server product.

I’ve been happy with this setup for quite some time. A batch of websites have been dished up from my server, reliably and consistently, for years, including this very blog, as well as New Life: New Zealand, my Moving to New Zealand blog. It was, for the most part, a set-and-forget system, needing only the most occasional of tweaks. But lately I’d noticed that the overall performance of my mini was becoming quite unacceptable. In addition to web- and mail-serving tasks, my mini also did light duties as a home media centre, and also hosted my iPhone, and so I use Screen Sharing to administer the thing, hidden as it is under a coffee table in the family room. Increasingly, this was becoming intolerable.

My lovely wife had recently returned from her annual visit to the US, and had brought home with her for me a new 2TB external hard disc; given that they retail over there for around half the price you can find them here in New Zealand, this was very much appreciated. Although I couldn’t be sure, I strongly suspected that the original internal hard disc of my mini, all 80GB of it, might have started to see the end of its useful life, and so I decided to install an operating system on the new external disc, and run my mini from there.

But which version to run? I had an installer disc for version 10.6, Snow Leopard Server, but I was sorely tempted by version 10.7, Lion Server. I particularly was tempted by the joys of wireless syncing that my iPhone, now running iOS 5, would now experience, and, well, why would I want to re-install an obsolescing system? Reading up on Lion Server gave me pause, though. Reviews such as this one concerned me, other sites had implied that multiple sites wouldn’t be possible, and I also got the impression that mail services would be hobbled.

In the end, I took a deep breath and installed. The software was surprisingly easy to install: once the standard client edition of Mac OS X Lion was up and running — and that was quite effortless, given that I already had made an installer DVD when I installed Lion on my laptop — a quick trip to the Mac App Store and a fifty-dollar spend later, and I had a new server. (Pricing, by the way, finally seems to be a bit clearer than it was before release.)

Lion Server's Server app

Server: Lion Server's part-replacement for Server Admin

All I could see, though, that was new for my $49.99 was a new application in the dock, Server. That, it would appear, was that, and it was, as far as I could tell, a rather severely hobbled version of the Server Admin application that used to power earlier editions of Mac OS X Server. Web services, for example, no longer had the flexible options that Snow Leopard Server used to make available; while multiple domains could quite easily be set up, there was a degree of inconvenience in the new simplification — instead of adding, say, domain.com and then configuring www.domain.com within that domain’s settings, each domain had to be set up separately to point to the same folder of web pages. Aliases and redirects can, of course, be set up — Apache still powers the web server, with Server only a graphical front-end — but now they need hand-to-hand combat between user and config files in the Terminal. While this still enables full access to everything you’d want to be able to do in Apache, it’s the very antithesis of Apple’s claim that Lion Server is The Server For Everyone, unless the only option Everyone wants is the choice of turning PHP on or off.

Not that turning PHP on is as helpful as it might be. PHP, for many people, me included, is useful only as long as it’s interacting with a MySQL database or two. The only reason I run PHP on my web server is to enable WordPress, my blogging and CMS platform of choice and one which is utterly dependent upon PHP being able to talk to MySQL. And maybe I’m being a bit too literal, a little rigid in my thinking, here, but I find that MySQL works so very much better when it’s actually installed. Which, oddly, it isn’t under Lion Server. MySQL was part of Mac OS X Server as recently as version 10.6.x, but it has now disappeared, with, typically, no explanation beyond the bare statement that ” Lion Server replaces MySQL with PostgreSQL.” There is speculation that the change is related to Apple’s dislike of GPL licences and Oracle’s acquisition of the product, and certainly it has resulted in plenty of unhappiness among users; at any rate, Apple’s documentation goes on to state that upgrades from Mac OS X Server 10.5.8 — that would be Leopard Server — and later will keep their functioning installations of MySQL, but, of course, this didn’t help me too much, given that I was performing a clean install.

A download of MySQL, which I then had to install, and configure, manually, was the workaround, but it did involve manual manipulation of a number of configuration files — again, not entirely what one might expect from The Server For Everyone, which now appeared to need renaming The Server For Everyone Who Only Wants to Configure PHP In Their Web Server And Not Run MySQL. Much time was spent searching the Web for help, and credit is definitely due to Tasman Hayes and Rob Allen. But I had my web server serving again, so onward.

Mail options in Mac OS X Lion Server

Lion Server's limited mail options

Next came mail, the other primary job of my server. The Server application was the obvious first place to look for settings, but options were quite limited. How, for example, could I specify the various different domains for which I wanted to provide service? Again, I could, if I felt like it, get my hands dirty tinkering with configuration files, but why should I? This functionality was provided in the Server Admin programme that was part of earlier iterations of Mac OS X Server — and there was my answer. Server Admin, however, was not part of the standard installation of Lion Server, but had to be downloaded separately from the Apple website. Once downloaded, it allowed me to set up mail service for the several domains I host, but, curiously, not webmail, despite that being one of the very few options actually offered by Server. (I eventually realized that, at least as I have my system set up, webmail is an intranet-only feature. Hmmm.)

Mail duly configured, I decided to tackle an issue I’d always struggled with in earlier versions of Mac OS X Server — virtual mail hosting. I host websites for both threelionstech.com and threelionsphoto.com (both seriously under re-construction at time of writing; you’re welcome to visit right now, but you might not be impressed), and also receive email sent to both domains. The problem I’ve had until now has been configuring my mail server so that mail to steve@threelionstech.com and steve@threelionsphoto.com can be picket up and dealt with by two separate IMAP accounts in my mail client. This can, I know, be done — I had it working, briefly, a couple of years ago. But the setting up of this feature is messy and not a little convoluted. My joy was unbounded, then, when I discovered that Server’s “Users” panel enables this feature effortlessly — simply set up a new account and specify the email address you want it to receive mail for, and you’re done. I was, at this point, almost (but not entirely — it still rankles) willing to forgive the hours of gaffing around that I’d had to deal with in setting up MySQL.

So now my server is happy again. If you’re reading this, then it’s still working. Much has changed, some things have been taken away, and the target market for Apple’s server software, especially since the demise of the XServe, is clearly home users. I’ll explore Wikis next — Apple are pushing them quite strongly, but since I run my own business I don’t know how much mileage I’ll get. I’ll tinker with calendar services. I’ll leave the “Next Steps” box (see the screenshot above) alone; it seems a little simplistic and facile. For now, my server is serving again.

Making power while the sun shines

Posted by steve on Aug 26, 2011 in Hardware, international, network, New Zealand, Personal

Tech, let us not forget, is not simply limited to Apple and the internet. You could be forgiven, to be fair, from reading this blog, for thinking that the world of technology begins in Cupertino and ends with the ‘net. But my most recent tech project is possibly the most spectacularly techie I’ve ever done. And it has no specifically Apple element in it, although it does involve the Web.

As has been documented quite extensively elsewhere, I moved a couple of years ago to New Zealand, where I find life to be, in so very many ways, a thoroughly pleasant experience. One of the few entries, however, in the debit column is the cost of living, and one of the most significant aspects of this headache is the price of electricity. While I’d never wish to return to living in Florida, among the few aspects of life there that I miss is the low, low cost of electricity.

As I said, we’re not going back, and so we — the lovely and talented Mrs. McCabe and I — decided that we needed to find a way of reducing our monthly spend on electricity. Back there, a unit — a  kilowatt-hour or KWh — cost, typically, around 8¢. Here, it’s more like 23¢. This does not, of course, please us, particularly when we were paying for electricity to heat our home. But what does please us is the abundance of sunlight that streams down on New Zealand much of the year, and so we have, finally, commissioned our very own solar-power installation.

The system is fairly straightforward. On our north-facing roof (this being the southern hemisphere), we have sixteen 190-watt solar panels. What this means, then, is that when the sun shines, and especially when the sun shines directly on the panels, we can expect to see up to 3KW of electricity being generated. Of course, we don’t expect to be getting that much power constantly, and, of course, we only get peak output when the sun is high in the sky, but we’re still optimistic that we’ll see plenty of power being generated.

The panels feed a 3KW grid-tied inverter, which takes the DC output from the photovoltaic panels and converts it to AC. This is essential for two rather critical reasons. Firstly, our home is, like most homes, an AC installation, full of appliances that are designed to take a 240V AC input. Secondly, and this is a rather cool and groovy consideration, the national grid in New Zealand is also a 240V AC system.

The practical upshot is simple. During the day, when our panels are generating a stream of as much as 3KW of power, whatever we need is used to power the house. Any surplus is sent off to the grid. When the sun either goes down or hides behind a cloud or two, then any shortfall is supplied by the grid. Meridian Energy, our new power supplier, will give us 23¢ for each unit we sell them — the same price they charge us for electricity they generate. In effect, we’re using the grid as our battery, storing any surplus we crank out during the day so that we can then use it back up at night.

So far we’ve had the system running for three days, and we’ve liked what we’ve seen. It’s late winter, or, if today is any measure, very early spring in northern New Zealand. We’ve bought about fifteen units from the grid, generated a dozen, and of that dozen sold five back. In other words, we’ve used, in total, about 22 units today, but only actually paid for ten. That’s a positive step; when the months and months of golden sunshine that characterise a New Zealand summer roll around, we expect to be, on a daily basis, net exporters, and, if we’ve done our calculations right, we expect that, over a year, what we buy from the grid should be, within a significant figure or two, pretty much what we sell back.

And let’s not forget the Web aspect. The inverter that converts our solar array’s DC output to an appliance-and-grid-friendly AC also contains a monitoring system and a web server, which, as soon as it was up and running, I patched into my own home server system, so it can be monitored worldwide. My very own personal power station is now online at threelionstech.com:81 — take a look at how much electricity we’re not paying for!

Fail wail: trying to get Steve’s TechBlog active on Twitter

Posted by steve on Jan 22, 2011 in Facebook, internet, network, News, Personal, Social media, Twitter

I think I may have tweeted prematurely. Last week, I posted the following bit of hubris on the Three Lions Tech Twitter feed:

Three Lions Tech is finally broadcasting on Twitter, Facebook and across the sub-etha network.

Three Lions Technologies, the corporate monolith for which Steve’s TechBlog is the warm, fuzzy and human face, finally had a Facebook page (be the first among your friends to like it!), to which I was now posting via TweetDeck, of which much — oh, so very, very much — to come forthwith, or at least after a few more cups of coffee. As part of a massive social media push that saw me posting like a madman to my moving to New Zealand blog, I also decided that I would also expand the online presences of my other online personae, and so I set about setting up Facebook and Twitter presences for Auckland’s premier Mac consultancy service. The Facebook experience was streamlined enough; all that’s required now is a little content, and all that’s required there is a little more coffee.

Twitter, on the other hand, has been an experience that can only be described as other. To be utterly blunt, I’ve never really got Twitter. From its beginnings in the late mesonettic period, I’ve been sceptical. Even more than blogs (to which I confess to being a late convert; viz this very blog, and this one), Twitter has long struck me as being as narcissistic, as vain, as woefully and dismally self-indulgent as any use yet found for the Internet. I have little interest in the colour of Lady Gaga’s underpants, or indeed whether she’s wearing any, and so a live feed of updates on the colour and deployment status of same seemed fabulously unnecessary. And yet, and yet…I saw a need to be using Twitter. Eventually, after much soul-searching, contemplation and beer, I did the only smart thing a man can do — I asked my wife.

My wife, among her many talents and wonderfulnesses, is the webmaster and social-media specialist for a major American corporation that, in the interests of national security, I should probably refrain from naming. Fortunately, however, she is willing to discuss her work with me, and so I grilled and interrogated her about the merits of social media networking; now, I believe, I start to see the point. And the point, put simply, is this — if everyone else is doing it, then I pretty much have to. Even North Bloody Korea’s got a Twitter feed. Yes, I know, this runs utterly counter to my mother’s “And I suppose if everyone else jumped off a bridge, you’d want to do that, too?” logic that I came to love so very dearly as a teenager, but I see the merit of it, which is why my various online presences are sprouting social-media badges like so many toadstools after a mid-summer downpour such as the one that has deluged much of the top end of the North Island this afternoon.

And so, duly put straight by my wife, yet again, I decided to set up a Twitter account for Three Lions Technologies. The setup started as smoothly as one would expect when dealing with one of the largest and most inescapable services in all of Netdom, one which has had five internet years — centuries in human years — to get things right. I followed the steps required of me on the Twitter website, and all went well, but as soon as action was required from the other end, it all went to custard.

In order for a Twitter account to become fully activated, to emerge from its shell so to speak (see what I did there? Shell, birds, tweet….get it?), a new user must respond to an activation email from Twitter. And in order for a new user to respond to an email from Twitter, Twitter must first send that email. And…well, that’s rather where it all broke down. I entered my super-secret private and personal email address, clicked “save,” and then looked in Mail for an incoming message. Nothing there, so I refreshed my mail — still nothing. I returned to the Twitter website, asked for a resend, and checked again. And again.

I run my own mailserver, and so I thought that maybe that was where the problem could be found. I tried using a different email address, at a different domain, but still Twitter failed to send a confirmation email. In sheer, utter desperation, I turned to The Google, who in turn referred me to Twitter’s help pages, where I found this remarkably helpful advice:

Use an email from a large domain.

Setting aside the fact that they clearly, clearly need a new tech writer, I looked further and came to the opinion that, no matter the size of the domain from which I used an email (I tried everything from the oddly small threelionstech.com to the paradoxically huge me.com; size clearly didn’t matter to Twitter), it wasn’t Twitter’s fault. Delivery to small domains is inconsistent. Spam filters are over-aggressive. Changes in the Earth’s magnetic field. The dog ate your email. Vint Cerf ate your email. A litany of excuses that all lead back to the basic problem: my Twitter account remains un-activated.

I do remain, however, unclear as to what that means. I can be searched for and found; I can tweet; I can follow and be followed. Still, don’t you expect better from Twitter?

Paying by the Bit: Internet access in New Zealand

Posted by steve on Jan 17, 2010 in international, internet, network, New Zealand, Personal

For reasons that would take too long to explain here, I moved to New Zealand about six months ago. I brought my life with me, including, among goods and chattels more varied than I had realized, my trusty Mac mini, which has been doing sterling duty as a Web and mail server for a year or more. My life also includes a wife and daughter, and they, not surprisingly, came with me too.

This has been an almost entirely unqualified success. The people in New Zealand are friendly, the food is astonishing, and the wine is spectacular. But, even in God’s Own Country, nothing is perfect. New Zealand is a truly splendid place to live in many, indeed almost all, regards. But for a techie – and I am, quite unashamedly and unabashedly, one of that number – there are definite quibbles, of which by far the largest is bandwidth, or the lack thereof.

When I lived in America, I was undeniably spoiled, as many Americans tend to be. Life, however shallow it may have been in other regards when one lives in Florida, was certainly easy from a connectivity point of view. My home office had a broadband connection with, as I simply took for granted, took for my birthright, unlimited data. I could slurp down, and throw up, all the data I wanted. The Internet was mine, all of the time.

But when we signed up for our New Zealand connection, we were stunned – stunned, I say! – to discover that the Internet, in New Zealand, is a highly limited and finite resource. We went from “all you can download” to “you get 20 GB a month, you’ll pay $100 a month, and you’ll be grateful for it” in the time it takes to fly from Los Angeles to Auckland (which is, now I come to think about it, a horrendously long time). This was a most atrocious imposition for the Internet junkies that my wife and daughter had become (not me, though, of course – I was far too virtuous, too self-restrained). For all that New Zealand had to offer, the narrowness of its Internet pipes was simply intolerable.

We opted for the “double your data” option (and the additional $30 per month that wasn’t optional), but we still find ourselves limited by 40 GB per month. I check the online usage-meter every few days (using, in the process, a few more precious bytes; oh, the cruel, vicious, bitter irony!), and issue imprecations to Wife and Daughter, reminding them that Facebook is a luxury, not an absolute necessity; they, as addicts always do, try to justify their endless status-checking as being entirely reasonable, indeed essential. I calculate the bandwidth usage of Skype and of YouTube; I flinch when I see Daughter download another Mary-Kate and Ashley movie from iTunes (that’s not really a bandwidth issue; that’s just on general principles – I’d cringe if that were happening if we had a free and entirely unlimited T3 connection direct to the trans-Pacific backbone). I have developed new and careful Internet habits: I use the “Open link in new window” option if I think there’s any possibility that I might want to visit a second link from the same page, to avoid potentially having to load the original page a second time, and Apple Mail no longer checks automatically every minute – each check uses several dozens of bytes, I’m sure, and they all add up. I even avoid visiting Japanese or Chinese sites, conscious of two-byte character sets using more than their fair share of bandwidth.

I check my Google Analytics numbers with conflicted emotions: every page view for our various blogs and online presences is, on the one hand, a cause for celebration – more visits, more revenue, more Internet fame and glory. On the other hand, those page views are also an occasion for more hand-wringing, since they were served up from my Mac mini, over my desperately and mercilessly limited Internet connection. I post photography from the beautiful country we now call home, but wince when I see that I’ve had visits to my site. Even the very act of visiting the Google Analytics Web site eats up a handful of kilobytes that I can scarce afford. Even writing this article is a painful experience; while the catharsis of venting about the primitivity of our connection is undeniably therapeutic, every adjective, every atom of invective, every single character I devote to letting the world know how abjectly deprived we are is one fewer byte that can be used elsewhere.

The reason for this caution is simple. As soon as we reach our allocated 40 GB – think about that for a second; it’s only a gig and a third per day, and the lovely and talented Mrs. McCabe, with whom I share everything, including my bandwidth, is a Web designer – a Gollum-like finger, somewhere in a dungeon buried deep in darkest Auckland, reaches out in the gloom, flicks a switch, and says “It’s dial-up for you. Your bandwidth is mine, it’s mine, my precioussss.” And that’s it. We’re reduced to an Amish connection, one so slow it would be more efficient to hand-write packets of data and strap them to the legs of carrier pigeons. Web pages load – if they load – in minutes, rather than seconds. YouTube is a pipe dream. Downloads, well, downloads don’t. There has been much discussion around the blogosphere in the last month about when the first decade of the 21st century will end. Here in New Zealand that discussion is academic – we’re still, at least in terms of Internettery, stuck back in the 1990s. My connection today is so slow that I half-expect to hear the dolphin-screech of a modem actually dialing in to Vodafone as I try to connect, and I’m grateful that I’m not on deadline for this article. Looking at the cave paintings of Lascaux would represent a faster data transfer than the one I’m hobbled with right now.

I have, I would like to stress, been more than diligent in my attempts to figure out where our precious data might be going. My first thought was Skype, given that Daughter spends much of her time video-chatting with friends back in the Northern Hemisphere. I installed iStat Menus; as far as I could tell, a two-way video conference was using only around 120 KBps. But Vodafone’s (for they are our current Internet provider) online “check your usage” tool was reporting that there were days when we used as much as 6.5 GB of data. The day we reached this number (our record so far, by the way) was a school day – I doubt, then, that Daughter’s Skyping can be the culprit (she would have needed 15 hours of non-stop chatting, and while she’s good, even she’s not that good).

I suspected that it might be my server. I was reluctant to give up running my own server after moving to New Zealand because I’ve localized a handful of my domains – mccabe.net.nz, threelions.co.nz, astralgraphics.co.nz – and it’s hard to find U.S.-based hosting services that handle .nz domains. I host my personal site, stevemccabe.net, as well as my clients’ sites, through a European hosting-and-reselling service, but they don’t offer anything in the Kiwi domain space, so I’ve bought my domains through GoDaddy. I’ve become familiar with GoDaddy’s DNS setup system, and so, frankly, it’s just convenient to register with them and then host myself. That said, GoDaddy’s pricing structure for hosting is Byzantine beyond belief (I’ve had clients in the past want me to set up their sites on GoDaddy – oh, the power of advertising, especially if it involves scantily clad ladies with large chests – and I now make it a condition of service that I provide hosting as well as design) and life was so much easier when I knew that I had all the Internet connectivity I wanted.

So I looked at the traffic stats on my server. This was a bittersweet experience because on the one hand, no, I wasn’t ploughing through my data, which was good, but on the other hand, this meant that my sites weren’t getting the traffic I would have liked. Still, at least that was another possible culprit struck from the list.

I issued the sternest of imprecations to my girls, and, to all intents and purposes, stopped using the InterWebs. But no matter how much we cranked back our usage, we still found that we were using – or, at the very least, we were being reported as using – at least several hundred megabytes a day.

It was time to talk to Vodafone. I contacted them several times, and received several different bogus explanations: I had viruses (_ahem_, my network is Apple-only), I had moochers (WPA2 password, a house built of brick, a large garden) – basically, it was my fault, one way or another. It certainly couldn’t be Vodafone’s fault. I pushed a little further. I was told to install a data tracker – I was even sent Vodafone’s recommended monitor, SurplusMeter. I installed it across my network, and it reported, of course, that I was using monstrous amounts of data. The reason was simple – it meters not only wide-area, but also local-area network traffic. My iMac, for example, was pushing through megabyte after megabyte, even though I had no applications open at all. Well, none that would use the Internet.

Except iTunes. But I wasn’t downloading anything. What I was doing was streaming music to my AirPort Express. SurplusMeter was recording every last packet that went out of the data port it was charged with monitoring – in this case, my AirPort card. I called Vodafone again, and explained that the numbers SurplusMeter was reporting were meaningless. They said I should shut down my local network for a day and see what my numbers were like. I did – and on that day my wife’s iMac managed not to report a single bit going in or out. Not bad for a Web designer who telecommutes between New Zealand and Florida.

Vodafone’s next suggestion was that we had a line fault. This was a possibility – I live in a very old house (we think it’s pre-war, but we’re not sure which war; my money’s on the Boer War) – and one of the call-centre people I spoke to noticed that, while a DSL modem typically reconnects four or five times a day, mine had already reconnected over a dozen times – and I still hadn’t finished my first cup of coffee. They assured me that they would look into this, but in the meantime I’d need to disconnect my phone line (a service, mind you, that I pay for) for a day in case there was a problem with my DSL filters. This may, or may not, have been the problem; I have no way of knowing. Maybe they’re still running tests. At the very least, they haven’t replied.

Finally, I wrote to Russell Stanners, CEO of Vodafone NZ, at the end of last month. A week or so later, I got a phone call from Vodafone, and, after a long chat, the rep who called me (also called Russell; hmm…) agreed to waive the $199 early termination fee and release me from the one-year contract that we would have been bound to until June 2010.

We’re switching to TelstraClear. I’m not doing this because they’re particularly brilliant, but because they do one thing that Vodafone don’t – instead of dialing us back to pecking-out-bits-on-a-Morse-Code-tapper speeds, they’ll keep on selling us more gigabytes. I’m willing to pay for a service (especially a service that I actually receive), but the idea that I only get my 40 gigabytes, and, regardless of whose fault it is, that’s it, I’m cut off like a naughty schoolboy, well, that really chafes.

So now we’re waiting. Our Internet connection went back to last-millennium speeds after only a fortnight this month, so we’re struggling – some evenings we can’t tell whether we’re offline, or just really slow. And although I signed up to TelstraClear over a week ago, I just had a phone call from one of their reps letting me know that, because of the Christmas and midsummer holiday backlog, they won’t flip our switch for another week.

I’ll be emailing this article off to TidBITS World HQ shortly. I have no idea when they may get it. The Word document that contains this piece is 41 KB, which, at my current Internet speeds, could take until March to send. It might be quicker for me to save it to a CD, swim to California with the disc between my teeth, walk across the country, and hand it to Adam Engst personally.
