Backup with rsync
July 18, 2007 — NikeshHow to back up over the network with rsync — and why you’d want to…
What’s so great about rsync? First, it’s designed to speed up file transfer by copying the differences between two files rather than copying an entire file every time. For example, when I’m writing this article, I can make a copy via rsync now and then another copy later. The second (and third, fourth, fifth, etc.) time I copy the file, rsync copies the differences only. That takes far less time, which is especially important when you’re doing something like copying a whole directory offsite for daily backup. The first time may take a long time, but the next will only take a few minutes
Google Hacking Database – Hundreds of great google hacks, tips and tricks.
July 11, 2007 — NikeshThis site is huge, without a doubt one of the best sources for google hacks on the web. It has 867 entries under 14 categories including “Files containing passwords” and “Sensitive Online Shopping Info” and is updated daily. It also has tutorials that show how to find these things yourself and more great(and non-google) google resources. here

Connect to Serial Consoles using UUCP
July 9, 2007 — NikeshMost Linux distributions include the UUCP application. Start UUCP with the command “cu -l [device] -s [speed]“, where [device] is the serial port you are using, such as ttyS0 (COM1) or ttyS1 (COM2), and [speed] is the speed of the serial console that you are connecting to.
# cu -l /dev/ttyS0 -s 9600
You may need to hit enter before you see the login prompt. If you see a bunch of weird characters, then you probably specified the wrong speed.
To exit, just type “~.“.

What is a Demilitarized Zone (DMZ)?
July 7, 2007 — NikeshCommon setups used for small and medium networks include a firewall that processes all the requests from the internal network (LAN) to the Internet and from the Internet to the LAN.
This firewall is the only protection the internal network has in these setups and it handles any NAT (Network Address Translation), forwarding and filtering requests as necessary. In most cases, the firewall also runs public services accessible from the Internet, such as web services and e-mail services. Within such setups, the DMZ is thus installed on and limited, we may say, to the server.
