Tags & Styles

Worked a little more on the site.

The big one is that i've added tags back to the pages. Once you start viewing a tag based index is sticks to it navigation until it's cleared or another is chosen. It works in pretty much the way you'd expect it to.

I've also linked in a stylesheet and started filling it out - but this is very rudimentary for now and not much more than enough to make things operate properly.

Powered by gcc and me!

Just for a little background, the blog itself is currently driven by a small stand-alone C program which is executed as a cgi script. The parameter processing is quite strict and just fails with a 4xx series error if anything (external) isn't right. At the moment it doesn't use any sort of database as such - the post text is simply a file on disk which is interleaved within code-generated text. A script generates several indexes in the form of C code from the filenames and a metadata properties file which is then compiled into the binary.

For now, to create a new post I have a small program which creates a simple post template and launches emacs directly on the server. If the file gets edited when emacs exits it then gets moved into the post directory and a metadata file is created. I then have to run make install on the binary to update the indices for the new file and any tags. This can eventually be replaced with a web-based editor with image uploads and so on if I ever get around to it.

It's just meant to be a 'quick and dirty' to get it up and running, but I somewhat like it's simplicity. I can't see it being of any particular interest or use to anyone but I will eventually publish it as Free Software at some later date.

Ahh stuff it

Got sick off all the snot in the logs so i've just moved ssh to another port and DROP all incoming ssh packets.

Well i'm doing a LOG + DROP for now just out of curiosity, but at least the failed login attempts have stopped cold.

I also put up a banner on a-hackers-craic redirecting here. This site still supports access via the year/month/title.html url's that match the ones on blogger (in addition to the hex-id ones); I was going to try to write some javascript to link or direct each post to the new one but it just seems like too much work today.

NotworkManager and other small things

Had a few problems with system updates lately. One was an upgrade to my remaining slackware system that broke a few things. First it wanted to run LILO after updating the kernel and I said no (I don't use it); not sure if that would have run the grub setup but what happened it wasn't run. Fortunately one of the kernels in grub still existed and booted so it wasn't too hard to fix.

It also broke NetworkManager - or rather, it stopped working again. It's been a flakey piece of shit forever but I thought it was finally 'stable' enough to use (despite a few quirks on that machine like it not automatically reconnecting after waking up).

Well not so!

It simply wouldn't connect anymore. No idea why. I went back to using rc.inet1.conf and it now works flawlessly - even reconnects after waking up. I'd already done this (or equivalent) on all my other machines, and it seems to be with good reason.

Crackers

I knew the internet was pretty slimey these days but actually setting up a server on the naked internet over the last weekend was a bit of an eye opener.

I noticed a massive spike in traffic on the 15th - given that the only service running at the time was the 'experiment' page 1GB seemed a bit off. It was just someone brute-forcing sshd. Since this server went live on the 26th of march it has processed over 300 000 failed login attempts, I imagine (but haven't verified) most of those were on the 15th. They certainly weren't me.

It's probably just a drop in the ocean compared to all the `real' traffic but it seems such a waste. Yay for bots.

So i've put a few mitigations in place over the last few days:

iptables rules to throttle new connections to port 22;
disabled root login through ssh entirely;
added a small blacklist using ipset.

I don't really want to have to maintain the last but i'll see how it goes.

Anyway it's sort of interesting to see the logins being used - root is obvious but hottie, mother and david don't seem too obvious.

Just for fun, here's the complete list of the usernames and frequency counts as of a few minutes ago.

Given this i'm not entirely sure it's a great idea to be running cvstrac - it appears to be unmaintained and so on, but it's only intended to be a short-term solution anyway.

Weather's too nice to be inside, i've done enough hours for the week, and a brother is in town so I think it's beer time!

Update 22/4/18: Thinking about the strange usernames, they are probably bot related accounts? Doesn't really matter.

Welcome to the ZedZone

First post on the new blog!

Experimenting with a very rudimentary partly manual, somewhat temporary posting mechanism until I can sort something better out.

Apart from setting this up i've done a little hardening on the software and the system. I tuned ssh a little bit. I added robots.txt to code.zedzone.au to stop indexers creating potentially infinite references. And I changed the blog indexing method and some of the url's for the same reason.

Mostly root login attempts via ssh, some looking for various (mostly php) server stuff (which isn't installed), and google bot getting a bit cross eyed at some of my url alias/rewriting/cgi mistakes.

time to put some money where my mouth is?

Due to some of the surveillance/tracking stuff in the news of late I went down a bit of a rabbit hole of looking at various 'secure' email and so on to do something about my gmail account and blogger.

I didn't really find anything I liked so instead i got myself a domain and a virtual private server to play with. I had originally intended to set something up on my home network via a static address but I never got around to it. Unfortunately getting a vps in switzerland is cheaper than even doing that - and that's with the virtual hardware and unlimited network bandwidth the latter of which is big buckeroonies in australia.

Well I still haven't done anything with it apart from setup apache with a nothing homepage pointing back to my isp hosted stuff, but it's at www.zedzone.au.

I'm still pretty lazy on the whole idea so it might take a while but i'll move my code and blog and eventually add an email to it. I don't particularly like working at that end these days (despite multiple shots at CMS subsystems) - too much security and complexity to worry about - but i'll see how it goes.

Although logging in here to post this did give me pause for thought on getting a bit less lazy about it. Despite never having offering it before blogger just gave me a page to buy and link a custom domain for a-hackers-craic.

Thanks google for once again mining my email to sell me something I already bought!

Next it'll be combat boots, kilts, and beer ... Adelaide Review article which includes bits about me (not sure why i didn't introduce myself as Zed that time, would've been better!).

Update: 15/4/2018. I finally got off my laze arse and spent a wet afternoon playing with the site - i've copied my internode (ISP) pages to the server, fixed some paths, and installed cvstrac for browsing the source (of some of the projects) via the new virtual host code.zedzone.au.

Still to do is the blog.

intel bugs, surveys, random shit

Well i've been following the whole "spectre" and "meltdown" saga over the last week or so. Apart from the pretty offensive development of branding (ugh) for a set of mostly unrelated bugs, loads of pro-intel FUD, misdirection and so on, it's been a bit of a fun ride of stupidity.

I haven't seen any patches for my laptop or work computers so far - one because i don't run any av software on microsoft? Ugh, what a fucking mess. I barely use that machine any more anyway, even less so while running that junk.

What's most appalling is that the problem has been sat on for 6 months under "responsible disclosure" while intel continued selling gimped hardware based on bogus benchmarks. And yet the linux and *bsd developers are either only just starting on or working on cleaning up fixes very recently - even intel is still fucking around with microcode updates.

The tech press, apart from The Register (who really broke this story) has been pretty shithouse too. "big nothingburger" for a massive massive security hole that isn't actually fixed by any of these OS kernel patches, merely mitigated. It's a big big serious problem, with big big serious costs, and the handling the disclosure has been an utter disaster - seemingly designed to spread fud about the impacts and costs. Still, if you relied on a single supplier - and particularly a nefarious piece of shit company like Intel - for any serious hardware investment, sucked in I guess? We all have to pay for your stupidity in the end regardless.

Blah.

I was insomniac[sic] late night and bored so I took the latest stack overflow survey. Apart from some pretty strange questions it's pretty clear why nobody reads my blog - no mention of almost any of the technologies I use day to day. Well at least they had the brains to identify C and C++ as two separate languages I suppose.

Some of the "order these in importance to you" questions I just skipped - I didn't care about the topic at all. A minor problem was a bit of confusion with "framework" "language", etc - where would OpenCL fit if they even included it? No CUDA either for that matter. Plenty of questions about advertising. No I don't use an ad-blocker but I turn off javascript which makes the site oh so much faster and kills most adverts as a bonus.

Sleep has been pretty miserable lately - probably a side-effect of overdoing it a bit, but I think i've gained enough weight again for the sleep apnoea to kick in. One example of overdoing it was the last weekend. Hit the beach Saturday afternoon, dropped in at a mates place - drank a carton of (bloody expensive) piss, went to a party (total strangers apart from him), was up all night whilst everyone else was falling asleep, back to his place to pick my bike up - for a couple more, another dip, and finally dropped by the pub on the way home for a fast (very slow!) one. Barmaid thought i was managing well all things considered but maybe that's because I always look exhausted and feel like shit? Nothing like a 36 hour day to get you tired; and then I was awake after only 4 hours of bloody sleep. For a couple of silly reasons I also got sunburnt to a crisp, oops.

Finally kicking into summer mode!

Another year down

Well that was 2017 I guess. Better than 2016 for me at least.

Pretty much recovered from NYE and NYEE drinking but I might take it easy for a couple of days. Waiting for the weather to heat up enough to get back to the beach, did some gardening. The replacement BIOS arrived today so I resurrected my PC too - still seems a bit funny so i'll probably get another one soonish but it works again for now.

I found a laser printer dumped on the side of the road so took it apart for something to do. Surprising amount of screws, custom springs, cogs, and lots and lots of tough plastic. Probably nothing I can do with it but the imaging unit is kinda cool - rotating mirror, a couple of lenses and mirrors. I suppose the more surprising thing is how much technology is placed in what is essentially a throwaway, one-use device. The "consumable" isn't the toner in these things, it's the whole machine; and what's worse is the realisation that the economies of scale mean it couldn't be done any other way. The world is so fucked.

When I wrote the following on the new jjmpeg home page:

Version 3+ is a complete rewrite from earlier versions which have effectively dissapeared from the internet after google code closed down.

I didn't realise just how true it was. Without google code and regular blog updates my projects have basically vanished from the internets - and more so from google search than others. I'm not particularly surprised there is no real interest in the projects themselves but effectively vanishing is a bit weird. Unless you're using some proprietary publishing platform you essentially don't exist.

Well i've got a few weeks off at least anyway; i'll take a break from the computer, watch some cricket, and basically just bum around a bit.
