I need to build a lot of servers at work on a weekly basis with various versions of RH and additional applications.
We use PXE/Kickstart to do this with selections made from a simple menu structure.
However, I keep hearing about Cobbler and although I have some documentation on it, I still cannot figure out any advantage it has over the pxe/kickstart method.
Hi,
i understood that there are several type of sockets: TCP, UDP & Unix.
i wondered, what is the performance advantages of unix socket of the other types?
isn't it equal to use UDP with localhost as destination over unix socket?
Thanks in advance,

What are the advantages for Sun Fire 490 over Sun Fire 480 R just from a server performance perspective? Or, are they both just about the same? (1 Reply)
Hi
I'm reading <learning the bash shell>. And in the section - 3.1. The .bash_profile, .bash_logout, and .bashrc Files
bash allows two synonyms for .bash_profile: .bash_login, derived from the C
shell's file named .login, and .profile, derived from the Bourne shell and Korn
shell files... (1 Reply)

cfetoolgraph - create graphs from a cfetool database
SYNOPSIS
cfetoolgraph name [--path|-p directory name] [--daily|-d] [--weekly|-w] [--yearly|-y] [--timestamps|-T] [--resolution|-r] [--help|-h]
DESCRIPTION
The cfetoolgraph command dumps graphs of averages for visual inspection of the normal state database. The files are in a format viewable by
"gnuplot" or "xgmr" or other graphical plotting program.
The command generates three or four files in a subdirectory of the database directory with a name beginning with either "daily", "weekly"
or "yearly", then "-", then either "snapshot" or the current time, if the -T option is used. The files are named "average", "stddev", and
"graph". The "graph" file contains both the averages and standard deviations, useful for plotting with error bars.
If a histogram file is present, a fourth file named "distr" will also be created, plotting the distribution of fluctuations about the mean
value.
If the -d, -w and -y options are all omitted, the default is to only graph the weekly database.
OPTIONS
--path|-p directory name
The directory in which the database specified by name can be found.
--daily|-d
Graph the daily averages database.
--weekly|-w
Graph the weekly averages database.
--yearly|-y
Graph the yearly averages database.
--timestamps|-T
Time-stamp the output filenames with the current time, in order to give a unique name.
--resolution|-r
Generate high resolution data (), instead of averaging data over periods of one hour to generate simpler and smoother graphs.
--help|-h
Prints a short help message and then exits.
EXAMPLE
% cfetoolgraph temperature --path /my/path --resolution
Create graph files of the weekly database in high resolution in the "/my/path/temperature/weekly-snapshot" directory.
