همانطور که در تصویر بالا مشاهده می کنید ، Open-E ما به درستی نصب شده است ، این نسخه طبیعتا برای محیط های آزمایشی مورد استفاده قرار می گیرد و Trial است و بعد از گذشت مدتی لایسنس آن منقضی می شود و طبیعی است که باید نرم افزار مناسب سازمان خودتان را سفارش بدهید. توجه کنید که نصب کردن Open-E تا حدود زیادی شبیه به نصب کردن نسخه های مختلف UTM ها و ESXi دارد چون شما تقریبا هیچ کار خاصی را از طریق کنسول مدیریتی Local این سیستم عامل نمی توانید انجام بدهید

Replication is now a key
part of most companies’
data protection and
disaster recovery arsenals.
Although there are several
deployment options,
host-based replication has
emerged as a cost-effective
and relatively easy to
implement alternative.

یکی از ویژگی های گنو/لینوکس که همیشه دوستش دارم بروز رسانی های اون هست که نسخه به نسخه تفاوت های زیادی داره برای نمونه ما دستور #dmesg از بسته : util-linux را مورد بررسی قرار میدیم
ورژن : util-linux-2.12a-24.el4
#DMESG(8) DMESG(8)
NAME
#dmesg - print or control the kernel ring buffer
SYNOPSIS
dmesg [ -c ] [ -n level ] [ -s bufsize ]
DESCRIPTION
dmesg is used to examine or control the kernel ring buffer.
The program helps users to print out their bootup messages. Instead of copying the messages by
hand, the user need only:
dmesg > boot.iss.onessages
and mail the boot.iss.onessages file to whoever can debug their problem.
OPTIONS
-c Clear the ring buffer contents after printing.
-sbufsize
Use a buffer of size bufsize to query the kernel ring buffer. This is 16392 by default.
(The default kernel syslog buffer size was 4096 at first, 8192 since 1.3.54, 16384 since
2.1.113.) If you have set the kernel buffer to be larger than the default then this
option can be used to view the entire buffer.
-nlevel
Set the level at which logging of messages is done to the console. For example, -n 1
prevents all messages, expect panic messages, from appearing on the console. All levels
of messages are still written to /proc/kmsg, so syslogd(8) can still be used to control
exactly where kernel messages appear. When the -n option is used, dmesg will not print
or clear the kernel ring buffer.
When both options are used, only the last option on the command line will have an effect.

SYNOPSIS
dmesg [options]
dmesg —clear

DESCRIPTION
dmesg is used to examine or control the kernel ring buffer.

-E, —console-on
Enable printing messages to the console.
-e, —reltime
Display the local time and the delta in human-readable format. Be aware that conversion to the
local time could be inaccurate (see -T for more details).
-F, —file file
Read the messages from the given file.
-f, —facility list
Restrict output to the given (comma-separated) list of facilities. For example:
dmesg —facility=daemon
will print messages from system daemons only. For all supported facilities see the —help out‐
put.

Restrict output to the given (comma-separated) list of facilities. For example:

will print messages from system daemons only. For all supported facilities see the —help out‐
put.
-H, —human
Enable human-readable output. See also —color, —reltime and —nopager.
-k, —kernel
Print kernel messages.
-L, —color[=when]
Colorize the output. The optional argument when can be auto, never or always. If the when
argument is omitted, it defaults to auto. The colors can be disabled; for the current built-in
default see the —help output. See also the COLORS section below.
-l, —level list
Restrict output to the given (comma-separated) list of levels. For example:
dmesg —level=err,warn
-l, —level list
Restrict output to the given (comma-separated) list of levels. For example:
dmesg —level=err,warn
will print error and warning messages only. For all supported levels see the —help output.
-n, —console-level level
Set the level at which printing of messages is done to the console. The level is a level num‐
ber or abbreviation of the level name. For all supported levels see the —help output.
For example, -n 1 or -n alert prevents all messages, except emergency (panic) messages, from
appearing on the console. All levels of messages are still written to /proc/kmsg, so sys‐
logd(8) can still be used to control exactly where kernel messages appear. When the -n option
is used, dmesg will not print or clear the kernel ring buffer.
-P, —nopager
Do not pipe output into a pager. A pager is enabled by default for —human output.
-r, —raw
Print the raw message buffer, i.e. do not strip the log-level prefixes.
Note that the real raw format depends on the method how dmesg(1) reads kernel messages. The
/dev/kmsg device uses a different format than syslog(2). For backward compatibility, dmesg(1)
returns data always in the syslog(2) format. It is possible to read the real raw data from
/dev/kmsg by, for example, the command 'dd if=/dev/kmsg iflag=nonblock'.
-S, —syslog
Force dmesg to use the syslog(2) kernel interface to read kernel messages. The default is to
use /dev/kmsg rather than syslog(2) since kernel 3.5.0.
-s, —buffer-size size
Use a buffer of size to query the kernel ring buffer. This is 16392 by default. (The default
kernel syslog buffer size was 4096 at first, 8192 since 1.3.54, 16384 since 2.1.113.) If you
have set the kernel buffer to be larger than the default, then this option can be used to view
the entire buffer.
-T, —ctime
Print human-readable timestamps.
Be aware that the timestamp could be inaccurate! The time source used for the logs is not
updated after system SUSPEND/RESUME.
-t, —notime
Do not print kernel's timestamps.
—time-format format
Print timestamps using the given format, which can be ctime, reltime, delta or iso. The first
three formats are aliases of the time-format-specific options. The iso format is a dmesg
implementation of the ISO-8601 timestamp format. The purpose of this format is to make the
comparing of timestamps between two systems, and any other parsing, easy. The definition of
the iso timestamp is: YYYY-MM-DD<T>HH:MM:SS,<microseconds><-+><timezone offset from UTC>.
The iso format has the same issue as ctime: the time may be inaccurate when a system is sus‐
pended and resumed.
-u, —userspace
Print userspace messages.
-w, —follow
Wait for new messages. This feature is supported only on systems with a readable /dev/kmsg
(since kernel 3.5.0).
-x, —decode
Decode facility and level (priority) numbers to human-readable prefixes.
-V, —version
Display version information and exit.
Colorize the output. The optional argument when can be auto, never or always. If the when
argument is omitted, it defaults to auto. The colors can be disabled; for the current built-in
default see the —help output. See also the COLORS section below.
-l, —level list
Restrict output to the given (comma-separated) list of levels. For example:
dmesg —level=err,warn
-l, —level list

Display help text and exit.
COLORS
Implicit coloring can be disabled by an empty file /etc/terminal-colors.d/dmesg.disable. See termi‐
nal-colors.d(5) for more details about colorization configuration.
The logical color names supported by dmesg are:
subsys The message sub-system prefix (e.g. "ACPI:").
time The message timestamp.
timebreak
The message timestamp in short ctime format in —reltime or —human output.
alert The text of the message with the alert log priority.
crit The text of the message with the critical log priority.
err The text of the message with the error log priority.
warn The text of the message with the warning log priority.
segfault
The text of the message that inform about segmentation fault.
