Monday, January 1st, 2007Potrebujemo tri komponente / all we need are this three components:
- sendEmail.exe – ukaznovrstični program za pošiljanje elektronske pošte / commandline utility to send e-mail // http://caspian.dotconf.net/menu/Software/SendEmail/
- pspv.exe – program za izpis t.i. protected storage / program to print out protected storage // http://www.nirsoft.net/utils/pspv.html
- autorun.inf – datoteka, ki vsebuje autorun zapise / file with autorun parameters // http://www.phdcc.com/shellrun/autorun.htm
- autorun.bat – datoteka, ki jo poženemo skozi autorun.inf / batch procedure that is called by autorun.inf
Edini način za zaustavitev takšnega početja je / The only way to disable souch activity is to:
- izključitev funkcije Autorun (uporabi Microsoftovo orodje – TweakUI ali mojo .reg skripto) / disable Autorun function (try using Microsoft tool – TweakUI or my .reg script)
- vključitev požarnega zidu navzven (SMTP promet se omeji / zapremo vrata 25) / turning the firewall on (SMTP traffic should be limited / closed port 25) (dodatna težava: kaj pa če poštni strežnik posluša na vratih 80?!? / extra truble: what if the mail server listens on port 80?!?)
- (mogoče najpomembnejša alineja) morda biti malce nezaupljiv :) / (maybe the most important thing…) Do not trust just anybody! :)
Ko se sprašuješ o firewallu in usmerjevalniku… / When you are asking about what kind of firewall and router to use…
Monday, January 1st, 2007V zadnjem času sem kar precej časa posvetil dvema odprtokodnima firewalloma/routerjema, m0n0wall-u ter pfSense-u. Celotna mreža kiWi-Fi network je postavljena na m0n0wallu. Obe zadevi delujeta super tudi v specifičnih režimih delovanja (transparent firewall, dodatni programski paketi (pfSense) …)
In the past weeks I spent some time to check the two opensource firewall/router programs: m0n0wall and pfSense. The kiWi-Fi network infrastructure is based on m0n0wall. Both produts work perfectly even in complex and specific environment (transparent firewall, extra packages (pfSense) …).
Že večkrat so me ljudje spraševali o znanih težavah – preveliki količini sej (še posebej ob uporabi raznih *donkey *mule in podobnih P2P programih). Za vse tiste je primeren spodaj naveden članek. “Računica” pa je nakako takšna: 32MB RAMa = 30000 sej. :)
Some people asked me about the known troubles using low cost routers – too many sessions (when using *donkey and *emule like p2p programs). For all that have questions regarding this problem there is a link below. The calculation is quite simple: 32MB of RAM = 30000 sessions. :)

Pozabljeno POP3/SMTP geslo v odjemalcu elektronske pošte? / Forgot your POP3/SMTP password that you use with your mail client?
Monday, January 1st, 2007S spodnjim orodjem lahko enostavno pridete do pozabljenih gesel. Brezplačen program je naredil Aleksandar Boros. (http://www.gsmblog.com/freeware/mpr/index.htm)
With the program, that is available on the below link you can recover your lost passwords. Freeware program was developped by Aleksandar Boros. (http://www.gsmblog.com/freeware/mpr/index.htm)

Enako bi lahko naredili z uporabo snifferja npr. Ethereal ali Wireshark. :)

The same thing could be achieved by using sniffer like Ethereal or Wireshark :)
