Formatting a USB Drive
Hi All,
I have a Drobo, connected to a CentOS 6.4 box. The box sees it as /dev/sdg.
I want to format it ext3 (as they dont support ext4) but when I try I get:
# fdisk -u /dev/sdg
WARNING: GPT (GUID Partition Table) detected on '/dev/sdg'! The util fdisk
doesn't support GPT. Use GNU Parted.
WARNING: The size of this disk is 17.6 TB (17592186044416 bytes).

I ave no idea what drive is in this system.
Can anyone point me in the right direction?

web collaboration packages.
Hello All,
Try as I might, I cannot get Zimbra 8.0.3 to install on CentOS 6.4, even
with --platform override. I followed some tutorials even that show the
result working and nada.
Can anyone suggest a good setup for e-mails erving, calendaring, web mail?
Web mail is particularly important for my wife so she can check e-mail when
she is at work.

Can anyone talk infrastructure with me?
Hi All,
I started a 501c3 (not-for-profit) organization back in February 2011 to deal with information archival. A long vision here, I wont bore you with the details (if you really want to know, e-mail me privately) but the gist is I need to build an infrastructure to accommodate about 2PB of data that is database stuff, stored video, crawl data, static data sets, etc. Right now in my testing of

CentOS 6.5 equivalents in CentOS 7
I tried to install CentOS 7 on a new system. It works.
However, I'm noticing small things:
1. system-config-network-tui is not installed and yum cannot find it. I
realized for this -- nmtui
What about firewall? I can't seem to understand the replacement from
system-config-firewall-tui

Do I need a dedicated firewall?
Hi All,
So my electricity bill is through the roof and I need to pair down some
equipment.
I have a CentOS 6.5 Server (a few TB, 32gb RAM) running some simple web
stuff and Zimbra. I have 5 static IP's from Comcast. I am considering
giving this server a public IP and plugging it directly into my cable
modem. This box can handle everything with room for me to do more.
Doing this would allow

Changing Root E-Mail address
Hi All,
I installed a new CentOS 5.5 box and I am getting a daily e-mail (I am not sure how this was triggered) with XNTPD logs, HTTP Error and Disk Space).
It is being sent to root at www.6colors.co which bounces, but I have a catch all so it does get to me.
How do I change where this e-mail is sent? I have tried in /etc/postfix/main.cd, master.cf, bounce.cf.default, etc and I don't see

Dedicated Firewall/Router
Hi All,
I want to build a dedicated firewall/router as I am launching a NPO and I can host this in my garage. (Comcast offered me a 100 x 20 circuit for $99/mo with 5 statics)
I used to run Untangle, but as of version 9, you are forced to use their build in protocol policies versus the firewalling I am used to (Deny All and then opening holes for specific IP's, etc).

file system replication
Hi Everyone,
I need to keep 2 systems identical. Mostly e-mail directories, web
directories, mysql, etc. The goal here is to have a 2nd system ready to go
it the first one starts to exhibit hardware issues.
What are options to have this happen? I'm going out on a limb and thinking
rsync but I haven't used it past just simple use cases.
Can anyone provide some insight for me?

Watching a directory
Hi All,
I am thinking about an idea, but it requires that I be able to watch several
directories for files that are added, deleted or maybe changed.
Let start with adding files. What tools are available for me to watch a
directory. In an example, if a file is added to a directory I want to run a
shell script that will do some conversation on the file to produce a second
copy.

Theoretical Firewall Specs?
So, the more I look at various ways to lay out my infrastructure, the more I am thinking about specs for hardware.
Starting with firewalling.
How does one determine the specs for a firewall?
What I mean is:
1. motherboard/CPU - p4? Dual-Core? Intel i3, i5, i7?
2. RAM? 4gb? 8gb? More? 32gb?
3. Obviously GB Nics!

NIC Throwing errors I dont understand
I am having an issue where eth1 is throwing some messages and stops
responding. Restarting networking doesn't work and also just bringing down
eth1 with 'ifdown' doesn't fix it. I have never seen anything like these
messages:
eth1: no IPv6 routers present
r8169 0000:03:00.0: eth1: rtl_counters_cond == 1 (loop: 1000, delay: 10).

Booting using another kernel
Hi Guys,
I am encountering this bug: https://bugs.centos.org/view.php?id=7656
I put in the CentOS 7 DVD and it starts to install and hangs with starting
x.
The suggestion was made in the bug report to boot using the 'kernel-ml' and
to be honest I don't know how to do that.
I build a machine that has 4 video cards in it. (2 x nVidia Geforce GT 970
and 2 x Sapphire Toxic R9 270x).

Moving hard drives
Hi All,
I have a server that is running nicely, except I have hit the maximum RAM (4gb) and I wish to add more.
It is an ASUS board, AMD X64 dual core, nvidia nic.
What I want going to move to is a dell board, Intel Pentium M dual code, which supports 8gb of RAM.
Can I just unplug the HD and move it to the new server and boot it up?
I assume that the NIC will need to be re-setup, but what

E-Mail Serving Options
Hi All,
What are my e-mail serving options? I need to host POP, IMAP and SMTP.
I must admit that non-windows e-mail hosting has always been a chore
for me. I remember QMail and QPopper IIRC.
