As an intermission (there’s more to come in the SPF series), here’s what’s changed on my server since, oh, about a year and a half ago:
- The OS is now Ubuntu Karmic Koala (9.10), and all the server’s running software comes from the standard Ubuntu packages, which means that whatever version is in Karmic1, that’s what I’m running here.
- I’ve switched, definitely, from Apache to nginx. It’s faster, more efficient, and ridiculously easier to configure (to put it in perspective, in terms of ease of configuration, it’s like OpenBSD’s amazing pf to the unholy abomination that is Linux’s iptables.) nginx works perfectly with the two pieces of software I use the most on my server, WordPress and MyBB, even while using a SEO plugin with the latter, which requires some non-trivial redirect rules.
- As I don’t trust any ISP’s email server to distribute the mail my server sends (mostly confirmation emails from my forums), and since most ISPs and companies these days block mail sent from dynamic IP addresses, I keep a 256 MB Slicehost slice, with a static IP address and, most importantly, reverse DNS, which I use as a smart host for my home server. The slice doesn’t have a lot of power in terms of CPU (and it’s not meant to), but, as bandwidth is much cheaper in the US than in my poor country, the “small” limit the cheapest slice includes is a lot; I use it for serving static files, mostly for my forums (all images and Javascript files are served from there), and I still have bandwidth to spare.
- I’ve stopped using a Squid proxy in my home network, and nowadays access the web directly… except for when I indulge in one of my newest weird habits: reading webcomics like this one or this one while having lunch or dinner. At such a time, moving instantly from comic to comic is a must… so I simply re-enable Squid (with more aggressive caching than I’d use for normal browsing; after all, existing comics typically aren’t going to change, are they?), do a nice little wget in my server to download and cache the entire comic, and then enjoy reading the whole of it (in as many meals as it takes) as if it was stored locally…
- A few changes to my email server’s configuration, mostly related to spam filtering… but I’ve been writing about that, haven’t I? And there’s still more to come.
- with updates, of course — people who are afraid of installing updates (“but… it might break something!”) are nothing more than mewling weaklings who are utterly incompetent as sysadmins; they should never be allowed within a mile of any server. Even one running Windows. [↩]
