TCPDUMP & Save Capture to Remote Server w/ GZIP
NOTE: When opening the files you might need to strip the very top line with notepad++ as its a mistake header This is useful when the local machine where you need to do the packet capture with tcpdump doesn?t have enough room to save the file, where as your remote host does tcpdump -i eth0 -w - | ssh forge.remotehost.com -c arcfour,blowfish-cbc -C -p 50005 "cat - | gzip > /tmp/eth0.pcap.gz" Your @ PC1 doing a tcpdump of PC1s eth0 interface and its going to save the output @ PC2 who is called save.location.com to a file /tmp/eth0-to-me.pcap.gz again on PC2 More info @: http://www.kossboss.com/linuxtcpdump1

Check tcp-wrapping support
This function returns TRUE if the application supports tcp-wrapping or FALSE if not by reading the shared libraries used by this application.

Create and play an instant keyword based playlist
It works best as part of a function, such as the following: MUSICROOT=~/Music function fplay { if [ $1 = '-v' ]; then shift 1 find -E $MUSICROOT -type f -iname "*$**" -iregex '.*\.(3g[2|p]|aac|ac3|adts|aif[c|f]?|amr|and|au|caf|m4[a|r|v]|mp[1-4|a]|mpeg[0,9]?|sd2|wav)' -print -exec afplay "{}" \; & else find -E $MUSICROOT -type f -iname "*$**" -iregex '.*\.(3g[2|p]|aac|ac3|adts|aif[c|f]?|amr|and|au|caf|m4[a|r|v]|mp[1-4|a]|mpeg[0,9]?|sd2|wav)' -exec afplay "{}" \; & fi }

List alive hosts in specific subnet
Works on any machine with nmap installed. Previous version does not work on machines without "seq". Also works on subnets of any size.

Suspend an ssh session.
This must be typed before any other characters have been entered on the line. Use fg, as usual, to resume the ssh session.

convert ascii string to hex
just a bit simpler

VIM: Replace a string with an incrementing number between marks 'a and 'b (eg, convert string ZZZZ to 1, 2, 3, ...)

Determine next available UID
Typical usage would be in a script that would want the next open UID in a range (in this case 500-600)

Merge PDFs into single file

Create a bunch of dummy files for testing
Sometimes I need to create a directory of files to operate on to test out some commandlinefu I am cooking up. The main thing is the range ({1..N}) expansion.
