IP over userspace: a play with vtun and IRC bots

Submitted by olecom

Once upon a time my friend pulsar Sheshka asked me to extend `vtun` to support traffic from user space (say, IRC clients). At that time he wanted to try to have free Internet (e.g. IRC was for free). And it was done so, right before I went to .CZ, where Internet connection was awfully fast.

There I did some work about IRC bots, connecting two via tunnel, as shown below:

Formatting forum posts in MS Word (phpBB case)

Submitted by olecom

To have a nice way of doing good forum post (about automobiles for example), one can use MS Word for inserting images, formatting, spelling. Problem is to have same view in forum.
Basically one can manually insert forum’s tags with very small font text, so it will be not noticeable. Other way, is to equip msword with a macro, which will do that job.

Via any terminal one can:
# set encoding

# set memory source
at+cpbs="ME"
# read items
at+cpbr=1,510

Result will be something like this:
+CPBR: 1,"375298077782",145,"olecom Oleg VERYCH/M"

PC (computer) powers on, but nothing happens next: no video output, no bios messages.

Really many PCs (mbs: epox, msi, gigabyte) were repaired from such situation by simple reordering of the memory in slots. Mainly, when it was in closest to CPU slot, i changed it to farthest. PC lives and boots again.
Если комп врубается, но ничего не показывает, попробуйте поменять местом слот памяти: если был ближе к процу, вставьте дальше.

regexp with `sed` are an easiest way to simplify manual analysis in bookkeeping, when plain text can be available from the ugly so called "software", and PCs are a form of typewriters.

Using scripted authentication

Submitted by olecom

I've found a way to use proposed in "ssh brute force" post method to auth users on some kind of services, server may provide, but where software may not support authentication at all.

Opinions on this auth for tinyproxy are welcome.

If you still have whose "autorun.inf puppies", which are being run by office rats, after all install && update && upgrade of the so called "anti-virus" software. Please, welcome!

Достали автораны и жирные ненасытные обновлениями антивирусы, которые до сих пор не могут с ними ничего поделать? Добро пожаловать!

Alternative power for LED head light

Submitted by olecom
on January 19, 2010 - 7:09am

I've bought a LED head light some time ago. Battery turned to be absolutely useless. It runs only 15 minutes instead of 12 hours. It has two holes inside, but there’s no liquid. Maybe all went off, and thus there’s no power… Even if had something, I don’t know what to put there, acid, alkali, water?..

Now i'm doing some kind of translator (to C), that can turn second to its functional equivalent -- first:

void handle_mcucsr(void) __attribute__((section(".init3"))) __attribute__((naked));
void handle_mcucsr(void)
{
    mcucsr = MCUCSR;
    MCUCSR = 0;
}

handle_mcucsr: sect[ion] .init3, naked!
	mcucsr = MCUCSR
	MCUCSR = 0

I'm back too. Back to my native places, native laguage etc. I've got some internet access and will share something (hopefully).

Want to start publication also in russian laguage. Let's see what will happen.

So, итак, я снова на кернелтрап.орг. Вернулся на родину, добыл немного интернета, и думаю начать публиковать информацию также на русском языке. Посмотрим к чему это приведёт.
