Paranoid pragmatic security type; I helped develop the AppArmor mandatory access control system. If AppArmor isn't a good fit for your security requirements, please consider running TOMOYO, SMACK, or SELinux.

For more information about me, including an abridged book list, see my careers2.0 profile. Or if you're old-school and want to see all my LaTeX skills on display, my old-fashioned resume is also available.

comment How do I enable 'highlight to copy' feature on CentOS6
Strictly speaking, highlighting doesn't copy to the clipboard but instead populates a selection buffer.

You will probably also need to include the output of ip addr show and ip route show. If ping(1) doesn't work, how about non-ICMP packet types? UDP or TCP?

comment How do I block url in Ubuntu internet shared connection?
The TLDP Transparent Proxying with Squid HOWTO is a little old, but should be useful.

Easiest is probably to use a proxy like Squid and force all web traffic through your proxy.

Why do you think umask is an option you can set with ext3 filesystems?

comment Deleted /usr/bin/python* by mistake, how can I recover it?
Man, that one is digging deeper into Python than I've needed in a while. Something is definitely odd that your sys.path doesn't include any directories /usr/lib/python* -- try to reinstall python-numpy or dpkg-reconfigure python2.7 to see if you can't "poke" whatever process left out the normal packaged directories.

@Paul: Are you just typing numpy at the prompt? Or import numpy at the prompt? You can't use plain numpy until you've imported the package.

True, but rm -i gets old after four or five files.

comment Changing terminal transparency with a command in Ubuntu?
In the cross-posted question there is an answer showing how to swap opacity / transparency -- showing that once again you cannot count on the lack of documentation to mean something is or isn't possible with the GNOME software.

comment Changing terminal transparency with a command in Ubuntu?
Note that the gnome-terminal(1) manpage was written by someone else because the GNOME team doesn't "do" documentation. The manpage just vaguely says something like "supports all VT102 and VT220 escape codes", but I fully expect it doesn't support all those codes and I fully expect they introduced new codes, too -- one of which might swap transparency on the fly. But just maybe. (The GNOME team is also known for removing configurable options whenever they think they can.)
