Based on experience at a number of jobs, Exchange may appear to be easy to
configure, but as soon as you get past the utterly basic configuration,
when management or other departments want more, it then becomes a major
headache.
I work for a US federal contractor these days, on site (civilian sector)
and they just gave up, and moved to M$ cloud for it. And most people HATE
IT.
Searching, if you're not using Outlook, is either terrrible or nonexistant
(they've started auto-archiving here, and I'm hearing there is no search).
In addition, if you go to 365, you are NOT BUYING the software, you're
renting the service. You will be paying every year, and a service contract
will cost, and, presumably, cost more every year.
Linux, once you get over the learning curve, is not that difficult to
administer. and there's a lot of online help (just don't expect us to do
your job for you, as a few folks who've posted here over the years seeem
to expect). You can also get contract help. If that's important, you might
consider upstream, who do provide paid support.
And it will cost a lot less than M$.

I don't know of any mail system that you cannot do that in. Every one
allows that.

Yup. And fixes come a *LOT* faster, often in hours or days, as opposed to
M$'s "there's no probem, it's your fault (insert one week to three
months), ok, ok, we've got a fix

Back in the last century, the old mainframe line was "nobody ever lost
their job by recommending IBM"; since the nineties, it's been
"recommending Windows", because that's all they know. We won't say how
much M$ pays, both for advertising, FUD, and illegal under the table
payments to manufacturers.

I would backup ALL your file systems off that disk, perhaps using a
Linux rescue CD, then configure the controller in the BIOS for JBOD, use
a rescue disk to build mdraid partitions, and restore your files from
the backups. you may have to rebuild the /boot/initrd on the system to
dump the fakeraid (dmraid) driver and enable the mdraid native linux
raid driver
Fake Raid like Intel Matrix Raid is NOT recommended for linux/unix systems

Have you gone to the drive's web interface on your local net? (http://[ip
of drive]) It has been my experience that these network storage devices
typically come pre-configured for smb/sftp/(and one other i can't
remember). The drive itself has a web interface in most cases allowing
you to configure users and permissions. After you configure (if needed) a
network discovery on the CentOS systems should show the NSD and allow a
connection as you desire. Mine does a smb connection to my Windows system
while I use sftp on all my Linux systems integrating file share seamlessly
through the NSD. I don't care to put smb on my Linux machines as it seems
to cause more trouble than it is worth; but, that is just a personal
preference.

Substitute CentOS-4Beta and CentOS-3.x and I agree with that statement.

I agree with that too ... it applies to CentOS upgrades to CentOS-4.0

I, like redhat, also think that backing up your data and doing a
reinstall and then moving your data over is the best and most reliable
solution.

Hey All,
I'm trying to build Tux Racer. I get:
checking for tcl8.5 library... no
checking for tcl83 library... no
checking for tcl8.2 library... no
checking for tcl82 library... no
checking for tcl8.0 library... no
checking for tcl80 library... no
checking for tcl library... no
configure: error: Cannot find Tcl library
The install manual says I may have to pass some options to configure:
Many people will be able to run configure without passing any options.
The more commonly-used configure options are:
--with-tcl-libs=DIR: Specify Tcl library location
--with-tcl-inc=DIR: Specify Tcl header file location
--with-tcl-lib-name=NAME: Specify Tcl library base name
I have:
[mlapier@mushroom ~]$ rpm -qa | grep -i tcl
tclx-devel-8.4.0-15.el6.i686
tclx-8.4.0-15.el6.i686
tcl-brlapi-0.5.4-6.el6.i686
tcl-8.5.7-6.el6.i686
tcl-devel-8.5.7-6.el6.i686
tcl-pgtcl-1.6.2-3.el6.i686
[mlapier@mushroom ~]$
The problem I seem to have is that I don't know what to use to replace
DIR: or NAME: to make it happy. Anyone know how to find the Tcl library
location, Tcl header file location, and Tcl library base name?
CentOS release 6.3 (Final)
Linux mushroom.patch 2.6.32-279.19.1.el6.i686 #1 SMP Wed Dec 19 04:30:58

I recently installed centos 4.1 and I'm trying to get samba working on it to serve windows boxes on a lan. I configured samba on the centos server using the graphical samba server configuration tool, which is similar to the samba setup on redhat 9 that I have successfully setup in the past. I setup samba user names and passwords with the same user names and passwords used on the win boxes.
I'm not able to access any shared samba folders from win boxes on the lan. I disabled the firewall on the centos server using the graphical security level configuration tool but I still can't access the samba shares. When I use a win box to connect to samba it will not complete the connection. It acts like the firewall is still running.
I disabled iptables on the centos server using the graphical services configuration tool but I still can't access the samba shares.
I can ping the centos server from linux and windows boxes on the lan. The centos server can ping other machines on the lan and can access the internet.
When I try to telnet into the centos server from win and linux boxes on the lan I get these messages:
On linux boxes:
"Unable to connect to remote host: Connection refused"
On win boxes:
Connecting To 192.168.1.2...Could not open connection to the host, on port 23.
No connection could be made because the target machine actively refused it.
Can anyone tell me what Im doing wrong or what I need to do to get samba
working on centos?
Thanks in advance,
Ken

Hi all,
Is there any pitfall when updating kernel with a software RAID-1
configuration?
Thanks.

Hi,
I am trying to configure linux bonding using balance-rr configuration. I
could not find a way to configure dhcpd.conf for this purpose and failed
miserably when I tried the following (dhcpd just failed):
host servername {
hardware ethernet [mac address interface #1] ;
hardware ethernet [mac address interface #2] ;
fixed-address 10.0.10.6;
}
In my understanding balance-rr would be issued a single IP address but
using 2 mac addresses in round-robin mechanism.
If this is true, how do I configure DHCPD to issue single IP address to 2
different MAC?
Sincerely,
Nurdiyana Ali.
