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

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

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

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://syslint.com/syslint/how-to-make-a-usb-boot-disk-for-centosrhel-from-iso-file/ ? 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:?

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

In order to create a bootable CentOS installation USB thumb drive, there are several steps one must follow.? The process often involves using a Windows box, which can be kinda annoying. The Linux Mint distro has what they call a "Hybrid" iso image. ?(see: ? http://community.linuxmint.com/tutorial/view/744 ) This image can be written to a thumb drive and used for installation simply by

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

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

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: # fdisk -l /dev/sdc WARNING: GPT (GUID Partition Table) detected on
