unprivileged users rebooting at console
I'm curious why any user logged in at the console can issue the 'reboot' command and reboot the system.? I've tested/verified this to work, and read some older posts about this.? If it were a bug, I suspect it would be fixed by now.
Also, if a user is logged into the console, and then logs in via ssh from another system, that user can also reboot the system from that ssh

Installing CentOS via USB thumbdrive
I've been poking at this for quite a while, and have never been able to get it to work.
I've found a couple links with some partial truths:

? http://brakkee.org/site/2013/05/09/creating-a-usb-install-for-centos-6-4/
The first one talks about converting a standard iso to a 'hybrid' image, using:?

minimal X applications needed to export to remote server?
I'm running a piece of network backup software called 'bacula', on a minimal CentOS 6.4 install.
I got everything working pretty well, but there's one piece giving me some problem-- a component which gives status info via a GUI.
In the past, on previous installations, I could ssh to the bacula server with the -X option, and run the application (called 'bat'), and it would

Dell R515 with PERC H700 - JBOD?
Hello, I'm curiuos if anyone knows if it's possible to set up a Dell R515 (which has PERC H700) to be JBOD.
It seems the only options are RAID0 or RAID1.
I read posts, where people say it can by done by making each disk its own RAID0.? This works, but it wigs out when that disk is removed, and forgets a disk was ever there (unless I go back in the PERC and fix it).
My plan is to have a

iptables port forwarding
I have a simple requirement/test I'm trying to perform, but having difficulty.
I have a system with 2 interfaces, BoxA:
eth0? 172.26.50.102
eth1? 192.101.77.62
My goal is to have a tcp port built on BoxA such that hosts on the 192.101.77.0/24 network can reach a port on a different box on the 172.26.0.0/16 network.
The target system is 172.26.10.120?? tcp/22
The port I wish to build is

TCP port to TTY/Serial Port?
Hello,
? I'm trying to configure my system such that I have a TCP port listening which will send all data it receives to a serial port.
ie:?? tcp/2112? -->? /dev/ttyS0
My goal would be to be able to:
Use netcat to create the listen and redirect to a serial port:
? $ nc -l 2112 > /dev/ttyS0
Then in another window, run minicom at /dev/ttyS0
Then in a 3rd window,
? $ telnet localhost

large SCSI RAID, replacing server
I have a system running CentOS 6.3, with a SCSI attached RAID:
http://www.raidweb.com/index.php/2012-10-24-12-40-09/janus-ii-scsi/2012-10-24-12-40-59.html
For disaster recovery purposes, I want to build up a spare system which could take the place of the server hosting the RAID above.
But here's what I see:

dd disk will not boot - can't find /dev/root
OS= CentOS 5.4, 64bit.
I've always had great luck using dd to copy entire disks, and booting on other systems.? However, I'm having difficulty with a couple systems.? I boot using an install DVD so the OS disk is quiet, and dd to my target disk:
# dd if=/dev/sda of=/dev/sdb bs=1024k
/dev/sdb is the blank disk.? The disks are 2T.? After a few hours the operation is complete.? But when I

Sorry
Sorry for the messed up replies. ?The web based icloud interface forces the writer to reply at the top of the email and if you try to write at the bottom by deleting a few lines of the message or selecting the whole message, deleting it, adding some spaces and then pasting back and go to the end it and adding a reply, it kills the indentation.

SELinux in CentOS 6
It keeps butting in when I try to install map software from Garmin

Interesting admin info: ipmitool
I've used ipmitool any number of times, but never for more than getting
info, or setting the server name on a Dell LCD screen. However, I had a
server screaming about intruder alert, intruder alert, er, "Chassis
intrusion detected", and I thought there might be a way to shut it up
(this after pulling the server and reseating the lid). A quick google
found, on the first page, an 8

Is CentOS-6.3-x86_64-netinstall.iso broken?
Hi,
I'm probably doing something wrong or misunderstanding how this is supposed to work.
I have written this ".iso" image to a DVD and booted from it. I then selected the first install option from the menu. I get some prompts and then I'm asked to specify where the media is. I assumed (there's that word) that I should just hit enter, thereby selecting the "from

vi defaults in 6.x
When I use copy/paste text into a window running vi, if there is a
single line starting with '#', in the pasted content, it adds a # to
all subsequent lines and indents each an additional level. Is there
some way to eliminate this bizarre behavior, preferably globally and
permanently so I don't have to repeat some change for every
machine/user where I might log in?

the at command
I was trying to use the 'at' command.
Does it not have "resolution" to the second?
When I run it with 'at -f /tmp/tt.sh "01/21/2013 15:20:45"
syntax error. Last token seen: 15:20
Garbled time
How do I run a command in the future including "seconds".

RHEL Subscriptions
Hello List Members.
I was recently approached by Dell stating that I HAVE TO renew my Red
Hat Subscriptions. I challenged this statement and was informed that
this has always been the case and that all servers I have bought off of
Dell over the years need to have current subscription!
I've been searching the Red Hat website to find where this is stated but
can't seem to locate this
