*der.hans: Intermediate shell scripting: getting more bash for your $*

*Description:*
Want to take your shell scripting to the next level? Interested in 
adding string manipulation and arrays to your arsenal? In shell math?

Shell still has the best system integration for stringing together our 
favorite command line tools such as ls, grep and sed. Better yet is 
doing some of that work in the shell without reaching for a forked 
program, especially inside loops. This presentation will cover 
intermediate scripting techniques and useful command line tips.

After attending this session, audience members will understand string 
operators, in shell math, indexed arrays and associative arrays. They 
will also be familiar with regular expressions, globbing and differences 
between the two. Finally, attendees will be familiar with useful builtin 
variables.

*der.hans: SSH and the shell-go forth securely*

*Description:*
SSH is the go to tool for sysadmins and developers for interactive 
connections to remote machines. It creates secure, encrypted connections 
between computers, even across hostile networks. Unless you accept keys 
without verification (DON'T DO THAT!!!).

SSH can also create tunnels for encapsulating other connections, 
including other protocols and data. Sysadmins can bridge protocols 
across networks for ease of access such as a one-off data sync. Devs can 
present the dev database on their desktop to ease use of graphical 
development tools.

After attending this session, audience members will be able to create a 
local tunnel from client to server, a remote tunnel from server to 
client, and do simple analysis of local vs remote evaluation of a 
command. Attendees will be able to use tunnels for SSH or sample other 
protocols (MySQL and HTTP), and tunneling via a third party system. They 
will also be familiar with dynamic SOCKS proxies and using SSH to tunnel 
graphical applications. Finally, attendees will also learn SSH 
configuration and command line tips for convenience of use, including 
using forced command to restrict an SSH key to one purpose.
