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.
