Fujtajbl vespolek!
Nechapu, cim jsem se o to zaslouzil, ale nekdo ma zajem o moji malinu.
Pripadalo mi divne, ze ledka na routru blika jak blazniva, kdyz by nemel byt skoro zadny provoz na siti a nasel jsem zajimave cteni v auth.log - ukazka nize je starsi, ty novejsi zaznamy jsou velmi podobne, jen uz tam nejsou radky koncici "POSSIBLE BREAK-IN ATTEMPT!". Snazili se vydatne, celkova velikost auth.log.x je pres 80MiB (nekomprimovanych).
Zatim jsem zamezil pristupu zvenku, ale rad bych to zase zprovoznil. Takze bych se chtel zeptat znalych a zkusenych, co zkontrolovat a prohledat, jestli se nekam precejen nedostali.
A pripadne nejake rady jak zlepsit bezpecnost.
Diky, Jirka.

Zdravicko.
Potreboval bych poradit, jak inicializovat usb.
Stahnul jsem si program pro komunikaci s boxem, ktery pravdepodobne chodil v ubuntu 6.06 - bude ten driver fungovat i v 8.04?
Readme.txt:
Kód: [Vybrat]
relook_usb.ko is the USB driver
in my ubuntu 6.06 system is placed under:

/lib/modules/2.6.15-27-k7/extra/relook_usb.ko

Your location might change if you have a different distro/kernel

You need to execute "mknod" to make device node in /dev directory
This is no udevd enabled so upon reboot needs to be run again

finally the relookusb application is called relookusb

have fun!

Kam by se mel ovladac umistit v HH?


skript mknode:
Kód: [Vybrat]
#!/bin/sh

MAJOR=`gawk '{ if ( $2 == "relook_usb" ) print $1; }' /proc/devices`;
MAX_DEV=32;

echo "major $MAJOR, max device $MAX_DEV.";

mkdir /dev/relook

for (( a=0 ; a<$MAX_DEV ; a++ )); do

Fujtajbl vespolek.
Ubuntu 8.10 II 64b.
Compiz-fusion v pohodě funguje, ale marně se snažím dostat výstup z grafiky v nativním rozlišení monitoru, tj. 1680x1050. Po úpravě xorg.conf se sice ve volbě rozlišení obrazovky 1680x1050 objeví a na monitoru se zobrazuje v odpovidajícím rozlišení/velikosti, ale není to úplně ono. Některé svislé čáry jsou rozostřené a menší písmenka se pak hůř zobrazují a text se stává blbě čitelný. V menu "information" na monitoru hlasi "current settings: 1400x1050"  :o, což je nesmysl, protože nakreslený kruh je skutečně kruh a není nijak deformovaný.
Dělá to se svobodným ovladačem, s nesvobodným nainstalovaným přes ovladače hardwaru i s nejnovějším staženým z ati.amd.com.
Při pokusech s nastavením jsem si všiml, že v prvotním nastavení se svobodným ovladačem je max. rozlišení 1360x768, ale monitor v infu hlásil 1280x768. Řekl jsem si, že tady asi někdo neumí počítat, hodil do kalkulačky 1280/768*1050, výsledek 1750 -> gtf 1750 1050 60 -> úprava xorg.conf a po restartu co myslíte?? Měl ho TAM! Obraz perfektně ostrý, monitor si lebedil, že má konečně "svoje" rozlišení a přitom si vesele ignoroval xorg.conf, kde byl jediný!!! řádek "Modeline ..." s rozlišením 1752x1050.
Jenomže bez akcelerace :( a na nesvobodné ovladače tahle "finta" bohužel neplatí.
A fčíl mudruj.
