VMware tools 1.0.10 on Centos 6?
by tony＠softins.co.uk 02 Sep '11

02 Sep '11

I have an instance of VMware server 1.0.10 hosted on CentOS 5, and it runs fine, with guests of CentOS 4, CentOS5 or Win2000. I have just created a new VM and installed CentOS6 on it, which also runs fine, except that I can't build the VMware tools on it. I get compilation errors when compiling the kernel modules, due to changes in the definition of struct net_device among other things. I saw a suggestion to use open-vm-tools, but looking at the RPMs on the Lucid site, it only talks about versions for ESX. I could try compiling from source, but I wanted to check first whether anyone here has succeeded in installing VMware tools on CentOS 6 for VMware Server.

New wireless controller
by Emmett Culley 02 Sep '11

02 Sep '11

I just installed an Asus PCE-n13 wireless card into one of my CentOS 5.6 systems. It uses the RaLink 2680 chip set and I was able to get the driver loaded using modprobe rt2x00pci.ko. I saw no error and now see that the module is loaded along with mac80211 and other dependencies. Now I need to know how to create the wlan0 device. I can find nothing via Google searches on how to create that device. I assumed the driver would do that upon loading, but now I expect some ioctl to the driver command may be required. I created an ifcfg-wlan0 file, but of course ifup wlan0 always returns device not found. Can somebody tell me where to start on getting the wlan0 device created? Emmett

CentOS 6 Partitioning Help
by Jonathan Vomacka 02 Sep '11

02 Sep '11

*Re-sending as it appears my original e-mail did not go through*. Good Evening All, I have a question regarding CentOS 6 server partitioning. Now I know there are a lot of different ways to partition the system and different opinions depending on the use of the server. I currently have a quad core intel system running 8GB of RAM with 1 TB hard drive (single). In the past as a FreeBSD user, I have always made a physical volume of the root filesystem (/), SWAP, /tmp, /usr, /var, and /home. In the partitioning manager I would always specify 10GB for root, 2GB or so for SWAP, 20GB var, 50GB usr, 10GB /tmp, and allocate all remaining space to my home directory as my primary data volume (assuming all my applications are installed and ran from my home directories). I was recently told that this is an old style of partitioning and is not used in modern day Linux distributions. So more accurately, here are my questions to the list: 1) What is a good partition map/schema for a server OS where it's primary purpose is for a LAMP server, DNS (bind), and possibly gameservers 2) CentOS docs recommend using 10GB SWAP for 8GB of RAM. 1X the amount of physical memory + 2GB added. (Reference: http://www.centos.org/docs/5/html/Installation_Guide-en-US/s1-diskpartition…) I was told this is ridiculous and will severely slow down the system. Is this true? If so, what is a good swap space to use for 8GB of RAM? The university of MIT recommends making MULTIPLE 2GB swap spaces equaling 10GB if this is the case. Please help! 3) Is EXT4 better or worse to use then XFS for what I am planning to use the system for? Thanks in advance for all your help guys Kind Regards, Jonathan Vomacka

Update to CentOS 6.0 without CD/DVD reader
by Timothy Murphy 02 Sep '11

02 Sep '11

I've had a disaster on my home network server; the partition table on the disk containing / has become corrupted, and testdisk has not enabled me to recover the table. If anyone can help with this I should be grateful. However, that is not what I am writing about. I've installed a substitute box - and HP MicroServer - which by a miracle has CentOS-5.6 installed on it. Now I'm wondering what is the best way to install CentOS-6, given that there is no CD/DVD driver on this machine. I have access to the internet, so I can download the CD/DVD . I know I could install through a USB stick; I'm just wondering if there is a more direct route. I should look this up, but I'm rather weary after installing dovecot, httpd, etc, and thought I'd take a short cut by asking you gurus. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

xvfb question
by bcb 02 Sep '11

02 Sep '11

First, I realize this might not be the right group. Please feel free to redirect me :-) I recently upgraded from CentOS 5.6 to 6.0. Since the upgrade, Xvfb will, on occasion, "just stop" (ie the process disappears from the system, as opposed to still being there but not working). I can't find any tracks anywhere that it might have left behind that might be clues as to why it stopped. There's nothing in /var/log that looks promising (nothing in messages or Xorg.0.log). Any other clues about where to look or command line options I should add? Thanks in advance, Bruce

Managing permissions for web folders
by Ruslan Sivak 02 Sep '11

02 Sep '11

We have a web folder /var/www/somesite that's a root for one of the sites. Apache serves files out of here. It is an svn checkout, so that updates could be done by using svn up. Everything has been going great when I use the root user to update, but now I need to give access to other people to make deployments, and it doesn't seem to be easy to do using regular users. I have created a group called staff and added the new user to it, lets say user1. I ran the following commands to set the permissions find . -type d -exec chmod 2775 \{} \; find . -not -type d -exec chmod 0664 \{} \; chown user1.staff . This allows the user to make deployments. Now comes in user2. User2 is also a member of group staff, so he can also make deployments. We haven't ran into any issues yet, but I believe as long as the files are owned by staff, both users can change the files, no matter which one of them owns it. Now we also need to give apache write access to a folder. Lets say /var/www/somesite/files. There are several options here. - We can add apache to the staff group, but this would give apache access to the whole /var/www/somesite tree. - We can change the group to apache. We will need to add user1 and user2 to the apache group. One of the problems with this is that the users would have access to everything that apache has access to. Another problem is that while user1 can run chmod -R user1.apache files, it will fail if the files are owned by someone else (like user2 or apache). Is there a way to get around this? Am I going about this the wrong way? Russ
