-* Port forwarding.
-
-  $ ssh -L 8888:www.linuxhorizon.ro:80 user@computer -N
-  $ ssh -L 8888:www.linuxhorizon.ro:80 -L 110:mail.linuxhorizon.ro:110 \
-    25:mail.linuxhorizon.ro:25 user@computer -N
-
-The second example (see above) show you how to setup your ssh tunnel for web, pop3
-and smtp. It is useful to recive/send your e-mails when you don't have direct access
-to the mail server.
-
-For the ASCII art and lynx browser fans here is illustrated the first example:
-
-   +----------+<--port 22-->+----------+<--port 80-->o-----------+
-   |SSH Client|-------------|ssh_server|-------------|   host    |
-   +----------+             +----------+             o-----------+
-  localhost:8888              computer      www.linuxhorizon.ro:80
-
-* Port listening.
-
-Connect to a server:
-
-  $ nc hostname port
-
-Be a server:
-
-  $ nc -l -p port
-
-* Simple filetransfer.
-
-Serve a file:
-
-  $ nc -l -p port < file
-
-Receive a file:
-
-  $ nc hostname port > file
-
-* Filesystem cloning.
-
-Serve the filesystem:
-
-  $ tar cOPp --same-owner / | nc -l -p port
-
-Receive the filesystem:
-
-  $ nc -w3 hostname port | tar xPp
-
-* Disk cloning.
-
-Serve the disk image:
-
-  $ dd if=/dev/hda | nc -l -p port
-
-Receive the image:
-
-  $ nc -w3 hostname port | dd of=/dev/hda
-
-* Encrypted, compressed and IP restricted filetransfer.
-
-If combining encryption and compression, be sure to compress first then
-encrypt when sending and reverse the order for receiving. Do not attempt to
-encrypt then compress. Compression works by finding patterns which are
-destroyed intentionally by the process of encryption. Also, though not
-required, specifying the IP address of the host that will be transferring the
-file is a good idea.
-
-Serving a compresssed, encrypted file from 192.168.0.1 to 192.168.0.2:
-
-  $ gzip -c < file | openssl aes-128-cbc -e -k thispassword | nc -l 192.168.0.2 12345
-
-Receiving, decrypting and decompressing that file:
-
-  $ nc 192.168.0.1 12345 | openssl aes-128-cbc -d -k thispassword | gunzip -c > file
-
-* Scan with nmap.
-
-TODO
-
-* Scan with netcat.
-
-  $ nc -v -w 2 -z hostname portrange
-  $ nc -v -w 2 -z hostname portlisting
-
-Where portrange is for example "10-20" to scan all ports between 10 and 20,
-portlisting is for example 11,20,135 will scan these ports.
-
-I just tried this on windows xp, and the comma separated list of ports does
-NOT work. Instead, use space separated list. eg:
-
-  cmd> nc.exe -vv -w 2 -z www.example.com 20-25 79 80 110 137-139 443
