Mortality Reminder

May 9, 2007 04:23 by gcm_uk
This one's a quick post. I was almost ran over at a traffic crossing at lunchtime by a woman in a Volkswagen Polo. Was too busy thinking about Emmerdale or something. Then two numpties five minutes apart almost ploughed into me in my car, turning into my lane. Obviously had no sense of speed. The first numpty in an MPV was only looking in one direction. The second one was a very attractive brunette, who thought it was amusing to pull out right in front of me. Nice one. I'm thinking twice about bringing my motorbike up to Scotland. May not live to see my next birthday! GC

Sticking it to da (spamming) man: Reloaded

March 15, 2007 14:48 by gcm_uk
I feel really good today. I've got my anti-spam tech completely up and running and I noticed a dramatic decrease in the amount of spam getting through to the email inbox.

I've unleashed a number of weapons against the shite including real time blacklists, greylisting, helo validation and much more.

I'm also proactively forwarding spams to the anti-spam technology for it to register the sender, and also adding lots of keywords to the Bayesian filter (which intelligently identifies spam emails).

85% of the email to my server over the last two days was spam. That's 85% less crap in the inbox! And 85% less lodged on my server. Hoo yahh!

Sticking it to da (spamming) man

March 14, 2007 00:04 by gcm_uk
I had three hours sleep last night! But it was worth it.

Let me explain. Are we sitting comfortably? Then I will begin.....


I logged into my server control panel a couple of months ago and noticed that the SMTP component (which relays emails to and from email clients) was registering above 200,000 messages transferred. A bit odd, I thought, but I assumed that it must just be the way the SMTP component works, so I didn't think anything of it at the time. Anyway, you'll remember from my last post about spam that one of my clients called up to tell me that they were sending out emails, but the recipients could not pick up the emails. I decided to take a look at the mail spooling area (which puts all emails in a queue for sending out) and I noticed a shocking 75,000 items! I was a bit pissed off to say the least, but I cleared out the mail spool, and normal email service resumed.....for a while.


A couple of weeks passed, and again the email-sending problem re-appeared. Now, at this point I started to become concerned. Something was happening here, and I needed to find out what it was. I cleared out the mail spool folder again (this time it contained 87,500 emails!!!) and tried to send some test emails. They still weren't getting through. I'd left the mail spool folder open on the desktop and in the ten or fifteen minutes of my email testing, the spool folder had collected another 15,000 emails! What the f-? I opened one of them up and then the problem became blindingly obvious. Some scumbag arsehole in the US of A was using a couple of my domain names to send out spam to the outside world(which thankfully I was not using on a regular basis; they contained holding pages for future projects). And they were doing it by the bucket-load. The SMTP log was showing 2million+ sent messages! I knew they were doing it from a home PC in the US because their PC's IP address was contained in the email headers, and it was a dynamically-assigned DSL address by Verizon in the US.


The most brute-force way of stopping them (because I don't need the affected web addresses to be up and running for the foreseeable future) was to close down the websites (hence stopping the mail portion for the site) and point the domain names to the servers of registration company (with whom I registered the domain names). The effect was INSTANT! The mail spooler wasn't getting clogged by thousands of emails in one go, and normal email service was resumed instantly.


This little escapade made me stop and think. It could have been much worse, and I guess I am lucky that my server hasn't been blacklisted already, even though it's not my fault. I just wish I could step on the face of the scumbag who abused my server! I would stick him in prison for the rest of his life.


Anyway wind your neck back in Graham! I decided to take some action last night and I've noticed a remarkable difference in the level of spam already. I installed an anti-spam technology on my server last night (I won't say which one!!) and even before it has been fully configured, it has already stopped quite a bit of spam. I've added lots of domain names to the blacklist already, and I basically banned the whole of Japan from sending incomprehensible (for us non-Japanese-speaking folk) emails. I've added some names to the whitelist (legitimate ones), and incorporated greylisting which delays emails and rejects ones that can't be confirmed (i.e. spam). Plus I'm shutting down all the domain names I do not use or can do without for the foreseeable future. It narrows the attack surface.


I'm fighting back against the spam scurge with a vengeance. I'm also going to collect the IP addresses of all the culprits and am going to report each and every one of them for abusing my servers. You want some, you spamming scumbag? You're gonna get some! You picked on the wrong guy!

SPAM: And I'm not talking about the bloody awful canned meat

February 24, 2007 14:47 by gcm_uk
Hey I'd been really looking forward to going to the local gym today. I've been sat for the last two weeks podging out on the great food and Tracker bars at work and ogling the beautiful women there (one of the best places for eye-candy I've ever known). I might actually get dating one of these women, if I could stop drooling and rubbing my thighs, going 'phhhhwwwoooooar'. It really puts women off, I've noticed. Anyway, previous to this pigging-out period, I'd been getting to the gym three times a week, but last week I just couldn't manage it due to the fact my arms were shot to pieces after the 220-mile motorbike journey from Scotland. I really fancied getting to the gym, then in the pool and sauna to chill out.

Then, just to piss me off, I got a support call from one of my website clients. Apparently he was having trouble sending emails from his office, but had no trouble receiving them. Which seemed a bit strange. Anyway, I took a look at my server, and on the face of it I could not see anything wrong. 'I know', I thought, 'I'll give the hosting company a call', with whom I've had no cause to complain up until now.

'Oh yes, sir, that will cost £60 per half hour to remedy', he gallantly announced over the phone. 'You f*ckin' what?', I thought. Yeah, he kinda got the point about where he could shove that advice. I'm a tight Yorkshire git.

So, after picking my jaw up off the floor, I went about trying to remedy the problem myself. I felt pretty pissed off at the fact I was having to try and solve a problem with THEIR proprietary component. I was also astounded that it wasn't covered in the normal payment plan. But nevertheless I'd did some investigation, and after a couple of hours, I found out the problem. The SMTP server component unceremoniously dumps a copy of all emails into a folder on a separate drive on my server, and there were 75,000 (yes I kid you not) emails in the email folder! 75,000!! No wonder the email server wasn't functioning! Which brings me to my point, eventually!

Spammers are scum! Why don't they just f*ck off? They are complete scumbags! I feel nothing but contempt for these people. I wouldn't piss on them if they were on fire. They hog all the bandwidth on the internet and basically cause no end of problems for most people who use it.

I really, really wanted to go to the gym today, not sit for four hours trying to figure out a f*cking spam-induced catastrophe.

I would stick them in prison for life, seize all their assets and make them pay financial compensation for all the other people's time the f*ckin' scumbags have wasted.

I don't need Viagra, I can maintain a perfectly normal erection, thankyou very much. I've had no complaints. And I don't need to be told 'I can shoot like a porn star with their products', especially when my mum is taking a look over my shoulder at which project I'm currently working on. She now thinks I am a blue-pill-popping pervert with a constant stiffy.

And can someone tell me what the f*ck Cialis is meant to be?

Yes, I got slightly wound up today. Anyway, come hell or high water, I'm going to the gym tomorrow.

Spam: slightly more problematic than the cruddy brown meat-like substance from which the internet annoyance of our age derives its name. GC

Y'know, I think I'm becoming more and more like Victor Meldrew every day

February 22, 2007 12:47 by gcm_uk
[No offence is meant by this article. Don't read it if you're easily offended. You were warned! I just want to get some things off my chest]

I start off by writing this blog in a beautiful part of Scotland. I really should be happy in such a nice part of the world, and I would be if it weren't for the tosser coughing every twenty seconds in the room next door. I can't tell whether it's a nervous cough or whether he's got the flu, but he's been coughing in there for hours, and that's been the pattern for the last month. Get a drink of water for f*ck's sake! My brain sub-consciously has taken over listening out for the next cough, and it's driving me crazy! And as I finish this paragraph, there is an ad-libbed groan like 'errrggh' after every cough. Hope he hasn't got bird flu. Anyway, this is one annoyance on a large (and growing) list of pet peeves I have with every-day life.

I'm pretty chilled out most of the time, but some things really get my heckles up.

Like I don't mind my brother using my toothpaste, but at least put back on the top. It's not rocket science! When I come to use the frigging stuff, it's dried into a white imperial mint-like residue, so I end up having to throw the tube away.

I don't mind my brother borrowing my (rather nice) coat. But I do mind if he f*cking smokes whilst wearing it! News flash bro', it's not a smoking jacket! If you're gonna do that, then buy your own on which to smudge nicotine stains.

Or like the stinky bastard who brings in the most pungent garlic-laden sandwich possible into the office, and sits there chomping away whilst the rest of his team recoils in disgust. I mean I like garlic too; it's a healthy food and it's good for your heart, but I think people who bring in that type of food purposely want to piss people off. Or don't mind making enemies of people who were once good friends.

Or like the people who seem to think they have the right-of-way at roundabouts. I can't count the number of times some arse has pulled out in front of me as I pass their entrance onto the roundabout. If you are one of those people, stop it! I can't tell you how much it winds drivers up. It is our right of way, after all. We're already on the f*cking roundabout! We'll be off it in a second or two! So just be patient.

I don't watch much current affairs these days either. The news programmes seem to revel in the misery of other people. Surely there are good things happening in the world? The worse the story, the better! You can see it in the eyes of the newsreader. Some poor bugger has just been ripped apart by an explosion! The newsreader is chomping at the bit to tell you. And I find it amusing just how many times they use the word 'allegedly'. Very amusing. They are reporting on things that may or may not be true. Great for them. They've just caused some more misery for a possibly innocent person, but what the hell, it pulled in the viewers didn't it? I also hate the way that each sentence has too long a pause in between, to try...and emphasise....the misery....of the situation. You just watch 'em do that next time you switch on the news.

Haha, oh yeah! Not to mention the veritable orgasm news agencies are currently enjoying with climate change. Sea levels are rising! Ooooh, yes! Parts of the world are suffering major drought unlike any seen in history. Ooh yes, harder baby, harder! The Atlantic Conveyor that pulls warm air up over the UK could soon be switched off due to the amount of freshwater melt coming down from the Arctic. Oooh yeaah, ooh yeeeah, I'm there! It's a bit late to worry about it now don't you think? Governments should have done something about it in the sixties when scientists first warned of the dangers. Never mind, if the UK is going to be warmer in the future, that's great! Good weather for motorbiking. I think Britain deserves a few weeks more of sunshine every year. We might not go mental on our holidays on the Costa Del Sol then. In fact, it'll be too hot to go to Spain.

I also hate the constant Z-list celebrity coverage that seems to make up 90% of the TV these days. Some Big Brother reject tosser has just bought himself a £800,000 Bugatti Veyron. Well done, mate! 57,999,900 people in the UK who can't afford such luxuries feel much happier knowing that. We'll all sleep better knowing that you're revelling in luxury bestowed upon you for acting like a knob on national TV, and pulling in some extra viewers. Get a proper job. The whole celebrity thing seems like a very selfish vocation to me.

Talking of Big Brother, any small respect I had for Jade Goody went out of the window after the tirade she threw at Shilpa Shetty. It was totally uncalled for. I can't think of any good reason for it. Great advert for the UK! Well done, mate! Class act! The one positive thing about Celebrity Big Brother is that the programme often exposes the real person behind the celebrity, and you can see them for the vacuous person they are.

The majority of my peeves are down to the apparent lack of respect or thought that some people seem to have for their fellow man. Manners don't cost nothing do they? The rules are simple. Treat other people with respect and 99 times out of a 100, you'll get it back, and more, probably.

Good night. Take care of yourself, and each other (thanks for that, Mr. Springer).
