Create Virtual Machine via HTTP or FTP
by cbulist＠gmail.com 08 Jun '14

08 Jun '14

Hi, I'm trying to create a Virtual Machine using Network Install mode (I tried HTTP and FTP). The HTTP/FTP server where the installation files are located is the Host Machine. The URL that I'm using is: http://192.168.1.104/inst and the Automatic detect option detects the OS without problem. When the installation starts I got an error: Unable to retrieve http://192.168.1.104/inst/images/install.img I tried different path but I always get the same error. The host machine is a Centos 6.2 (2.6.32.-220.el6.x86_64) I really appreciate any help with this problem. Thanks in advance,

idea: "hybrid" iso images?
by Joseph Spenner 30 Jan '14

30 Jan '14

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 performing: # dd /path/to/image.iso of=/dev/sdb (where /dev/sdb is the thumb drive device). This thumb drive can now be booted and used for installation. The same image.iso file can be written to CD/DVD to create the installation media as well. Is this a complicated ISO build process? I'm frequently installing to systems without CD/DVD drives, so this would come in handy. Thanks!

Building CentOS 6.2 custom install media
by Daniel Drake 14 Sep '13

14 Sep '13

Hi, For the OLPC school server ("XS") we are planning to move from our dated F9 setup to CentOS 6.2. Thanks for all the effort involved in producing this distro. One important part of this project is a 'respin' of the install media - we need to add a handful of packages from external repositories, and maybe run a command late in the install. Are the scripts/configurations used to produce the CentOS official CD/DVDs available? I guess this would be our most reliable/sensible starting point. I am familiar with pungi, kickstart, anaconda, etc, so just a simple git link would be enough to get me started. Thanks, Daniel

Help with thread Centos 6.4 won't reboot on install
by Robert Benjamin 26 Jul '13

26 Jul '13

Newbie here. Need help with a thread that has about 25 posts. No replies in a few days. The thread is in software support for centos 6 and the subject of the thread is Centos 6.4 won't reboot on install. Have had limited success in getting a login screen but once I logout, I can't get back in again. It was mentioned in the thread that the problem is likely in Network Configuration. I have no GUI (gnome) no mouse, no terminal, and keyboard use only with Ctl+Alt+F2. Can login as root but have no luck getting the GUI to appear or to get a user login screen. Thanks in advance for your help. Bob

Having difficulty exporting display
by Yves S. Garret 08 Jul '13

08 Jul '13

Hello, This is my issue, my remote machine (CentOS 6.3, hosted in Azure windows environment) has an application that I need to test on my local box (CentOS 6.4, a laptop behind a router). Now, this is what I'm doing and the issue that I'm encountering: Local: $ xhost + $ ssh -X someusername(a)somehostname.net -p 49283 Remote: $ export DISPLAY=192.168.1.6:0.0 $ xclock ... and nothing, it just sits there and no xclock shows up :( . I'm fairly convinced that this is due to my router, but I don't know how to deal with it. Any ideas? Am I way off in my guess?

No more support for chrome/chromium on rhel6
by Robert Arkiletian 26 Jun '13

26 Jun '13

https://plus.google.com/u/0/100132233764003563318/posts/Y1s6T44Soby Not 100% this is true but the problem apparently is that rhel6 uses an old version of gtk2. If this is true, then it affects my school and my students. I like google-chrome and it works very well with google services. I was planning on using C6 for a long time. Does anyone know of a repo that intends to keep Chromium working for C6? -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada

Re: [CentOS] sieveshell fails to start on CentOS 6.0

Try specifying both --user and --authname as appropriate. sieveshell can be misleading in its error messages, and you may actually have an authentication error rather than a connection error there. You could run it under strace to make sure. Devin

Does that mean anything? Thanks for any advise on this. Greetings, J. Opensource Software is the future.

Can anyone else reproduce this? At work we have a mirror, so I tried at home with a manually installed centos and internet upgrades. No difference. TIA, -- Groeten, natxo
