Hello: I have a Supermicro SuperServer 5015P-TR. It has a Pentium D and is running CentOS x86_64. Can this machine use 8GB RAM? I think it should because it is running a 64 bit OS, but I am concerned because it is fundamentally 32 bit hardware. Anyone have any experience in this area?

Hello: On a CentOS5 machine I set up for a client, in /etc/aliases, I set root's mail to forward to my email address so I can get notices from cron, etc. Unfortunately, I am now getting a lot of spam which is sent to root at theservername.com How can I tell sendmail to not accept external email to root?

Hello: I followed the instructions here: http://www.centos.org/docs/5/html/5.2/Installation_Guide/ch02s04s01.html to put isolinux on a usb drive. When I boot from the usb drive, the installer comes up and I can do a network install. I have to say that is very impressive! But, since I have a 4GB usb drive, I am thinking I can load the rest of the installation onto the usb drive so I do not have

Hello: I am trying to set up user quotas on my /var partition to enforce limits on user's mailbox sizes. The machine is running CentOS 5.

But, if I do: repquota /var It is telling me that one of my users is currently using 10264 blocks. But, if I look at

Hello: I have a subversion repository set up in /usr/local/svn/MyProject. For security, I have that directory set to apache as the owner and group and all files are mode 700. I need to run a svnsync command as the apache user so it may write to the repository. I tried this command: su apache -c "/usr/bin/svnsync sync https://svn2.jammconsulting.com/svn/MyProject" But I get this

Hello: I tried posting this to the subversion mailing list, but that does not seem to be taking the post so I am hoping this list can help. I am using svnsync installed using yum on my CentOS 5 server. I am trying to tell the sync command to save the certificates and credentials in a directory, but it does not seem to be doing so. I created a directory /usr/local/svn/MyProject.config To run

Just to chime in here, what I use is another file that is transferred last. It can be zero sized. Just some name you look for and then delete when you are done for next time. It doesn't matter how long that one takes because you will know that the important files are already transferred. chuck -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at

Hello: I have a machine running CentOS 5.2 I added two IP addresses to eth0 by copying /etc/sysconfig/network-scripts/ifcfg-eth0 to /etc/sysconfig/network-scripts/ifcfg-eth0:0 /etc/sysconfig/network-scripts/ifcfg-eth0:1 and changing the relevant IP info. I am now seeing outbound connections failing at my firewall from services like NTP, etc. since they are now using a source address from one

Hello: I have a server set up a CentOS 5 server for a client to push files onto using FTP. I have a cron job to process the files and move them to another directory. Sometimes, the cron job executes while the client is still uploading a file (Some of them can be large) and I get a partial file. Is there a way to tell when a file has finished uploading? I am using the vsftpd daemon installed

Hello: I have a server running CentOS 4.4. I just did a yum update and then rebooted the server. After the reboot, it stops after printing GRUB on the screen. Any ideas what happened?

Hello: I tried this command to tar up a set of data files updated since yesterday (The data directory contains multiple files with varying dates): /bin/tar -z -c -N 2009-03-25 -f /tmp/test.tgz data When I look at the content of the test.tgz file, it looks like it copied the content of the entire directory, not just the newer files. I am on CentOS 5. Any ideas? Thanks, Neil -- Neil

Hello: I have a machine running CentOS 5 x86_64. It is running apache httpd and tomcat. For some reason, after running for a few days, web requests stop responding. It happened again this morning.

Hello: I tried to unsuccessfully install a guest on xen. It failed when it tried to connect to the display since I installed the OS without a graphical environment. When I do an xm list, I do not see the guest, but if I try to do virt-install with the same guest name, it tells me the domain already exists. I tried xm delete on the domain but that also tells me the domain does not exist. Any

Hello: I need to build a system like this for a client: I will have a Linux server in a data room. It will have a web interface where the users may upload files. The files may be: Word, Excel, PDF, tif files, etc. Now, using the web interface, they should be able to brig up a list of files, select a set to print and send them to a local printer that is running as a shared printer on a Windows

Hello: According to the Red Hat Virtualization Guide, Windows Server 2003 32-bit will only run as a fully virtualized guest on an AMD64 system. I thought I have seen a lot of discussion about running paravirtualized Windows on CentOS. Is that a bad idea?
