Clonezilla is pretty versatile but has limits going from disc's with
different sizes. I will use the app best suited to the fs in question.

I have an issue with only a few domains sending mail to a company's exchang=
e server.
Topology is as follows:
Internet -> PIX -> logical interface / vlan -> HP switch (interface tagged =
into applicable vlan) -> ESXi server -> vm (ASSP/CentOS Postfix MTA) -> HP =
switch (out of vlan) -> physical HP server with E2003.

Mail comes in, ASSP logs it, postfix logs it, queues it, attempts delivery =
to my exchange server and somewhere com gets mangled. I can't tell what's w=
rong at the postfix side, but the exchange server doesn't even log it despi=
te the mail getting queued and released?

How can I dump this interaction and more specifically sort it to see only t=
hat transaction. Server is busy, there would be a lot of data on a continuo=
us dump. Given the topology there is room for much issues and I don't doubt=
the issue being from ESX forward (seen silly network issues on ESX before)=
.

Thanks for any input!

How does one redirect output of a command such as 'make' to a file
_and_ the console?

Thanks!

Yeah, looks like rpmforge has an issue atm:

# yum --disableplugin=3Dpriorities whatprovides */libFLAC.so.8
Loading "fastestmirror" plugin
Loading mirror speeds from cached hostfile
* rpmforge: apt.sw.be
* base: centos.arcticnetwork.ca
* updates: centos.arcticnetwork.ca
* addons: centos.arcticnetwork.ca
* extras: centos.arcticnetwork.ca
No Matches found

But flac-devel provides libFLAC.so, so maybe you need a newer one than Base=
provides?

>In the future, when upgrading the kernel, will future initrd's be built with my current modules or will I have to manually create new initrd's after each update?

Good question that I would love to know as well. I thought /etc/sysconfig/mkinitrd handled
this, but not ripping apart the srpm of a new kernel, I don’t really know if it bothers doing
making the initrd.

Given the rest of the requirements, I would say something like:
http://www.mini-box.com/M200-LCD-Enclosure

Find a distro more suited to the low power/mem environment like
busybox or something.

I have some pm files I want to add, these seem to be custom modules deliver=
ed
with a package I am trying to install. I don't want to run its script as it
manually installs many modules available in base so I will simply yum those
in. How can I add the pm files, I assume I have to update something in Perl
so that it knows these are available wherever I put them?

Thanks!

You imply the *only* reason for outbound filtering is stop a hacker. In some
environments it serves as an additional layer of protection against other problems
related to configuration/application issues as an example.

Watch the wrap, or search google for "sata configuration enhanced"
it's the first hit...

Enhanced/AHCI for SATA drives under Linux.

Off the top of my head:
$cdrecord -scanbus
See what device your burner is (Mine is 0,2,0)...
$cdrecord -fix dev=3D0,2,0

HTH,

Use cdrecord to fixate the disc (--fix).

Heh, Actually you don't "have two SATA controllers for a single disk drive"
but you have two controllers.

As the last poster suggested, use AHCI for Linux.

jlc

Is your Mass Storage Controller configured as IDE instead of AHCI?

>What am I missing? Is it odd to have two SATA controllers for a
>single disk drive, or is that at all relevant?

You don't, it would be odd :) What model of mobo?
I would be curious to check the manual, it's been a while since I
worked on an ICH8 chipset so I wonder about the storage config setting.

It's the smallest allocatable size of any PV you can give to an LV.
Think of it like Allocation Unit Size. Also as pointed out above some
limitations arise in different versions of LVM. RH defaults to 32M I
believe...
