Is there an nmap line that will auto-detect my current IP address and subnet mask, and run a ping-scan on all? For example:
#> nmap -sP 0.0.0.0
Instead of manually:

the sysadmins are present in the sudoers files of all environments, but other sudoers are not. Different environments all have slightly different sudoers. Most of the time, 90% of users are the same, and 10% vary so we cannot have only one sudoers file for everything.

Hi, I need sudo for a command for any path under a particular area. Example:
sudo mycommand /opt/apps/myapp/...

Thanks.

I'm setting up an Ubuntu 11.04 server VM for use as a database server. It would make everyone's lives easier if we could have folks login using windows credentials and perhaps even make the machine work with the current AD-driven security we've got elsewhere.
The first leg of this was really easy…
