Raising the daisy family

Raising the daisy family
Bellis perennis is a common European species of Daisy, often considered the archetypal species of that name. Many related plants also share the name “Daisy”, so to distinguish this species from other daisies it is sometimes qualified as Common Daisy, Lawn Daisy or occasionally English daisy. It is native to western, central and northern Europe. The species is widely naturalised in North America,[1] and also in South America.
Growth
It is a herbaceous plant with short creeping rhizomes and small rounded or spoon-shaped evergreen leaves 2–5 cm long, grows close to ground. The flowerheads are 2–3 cm in diameter, with white ray florets (often tipped red) and yellow disc florets; they are produced on leafless stems 2–10 cm (rarely 15 cm) tall. The lawn daisy is a dicot.

January 8th, 2010schroot – chroot for any users
January 7th, 2010From manpages: schroot allows the user to run a command or a login shell in a chroot environment. If no command is specified, a login shell will be started in the user current working directory inside the chroot.
I’ve been trying some virtual machines solutions to execute some programs 32bits in my machine. But it’s take very time, start a xen VM or virtualbox. Often this solutions needs some maintain additional costs to setup a X server to run any X-based program.
OpenSSH logging with ChrootDirectory
January 7th, 2010Finally following up on the previous article on the subject, I found some time to investigate logging what happens in an internal-sftp session using rsyslog.
Making syslog available in the chroot
Simply create a dev directory in each one of the chosen user chroot directories.
# mkdir /home/user/dev
Configuring rsyslog to probe the new logging source
Simply drop the following contents in /etc/rsyslog.d/sshd.conf :
# Create an additional socket for some of the sshd chrooted users. $AddUnixListenSocket /var/fileserv/dev/log # Log internal-sftp in a separate file :programname, isequal, "internal-sftp" -/var/log/sftp.log :programname, isequal, "internal-sftp" ~ » Read more: OpenSSH logging with ChrootDirectory
inux: rm and the ‘Argument list too long’ error message.
January 6th, 2010Linux: rm and the ‘Argument list too long’ error message.
Linux: rm and the ‘Argument list too long’ error message.
Let’s say you wanted to delete all the files in a directory that begins with the word ’spam’:
[root@yoursite filter]# rm spam*
bash: /bin/rm: Argument list too long
ERROR!
This happens when you are trying to delete too many files in a directory at the same time – it seems rm has limits ….
To solve the problem:
Use ‘find’ to pipe all the matching files to ‘rm’, one at a time.
[root@yoursite filter]# find . -name ’spam*’ | xargs rm
