+The second example (see above) show you how to setup your ssh tunnel for web, pop3

+* Simple filetransfer.
+
+Serve a file:
+
+ $ nc -l -p 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
