Hi, I try to build experimental networks with Xen and stumbled over the same problem that has been described quite well by Mark Doll in his posting "xen_net: Failed to connect all virtual interfaces: err=-100" here: http://lists.xensource.com/archives/html/xen-users/2005-04/msg00447.html As it was still present in 2.0.6, I tried 3.0-devel and found NR_PIRQS and NR_DYNIRQS had been

Sorry for the frantic nature of this message, but we need to allow pings on our firewall so our ISP can test things.

To anyone who is well versed with samba, I am currently setup with ip masquerading with a cable modem connection to my ISP. I have an error message that continues to show up on my linux box. It says: 10.58.0.1 sent an invalid ICMP error to a broadcast. This means it is my linux box sending an invalid packet out through my modem. This started to happen when I installed samba. So I hav come

Configuration: (2) Dual Core Opterons 8GB RAM Apache used to balance 40 mongrel instances We receive Application 500 Errors. Nothing suspect appears in the log, so we are at a lost as to what to do next. Any advice would be welcome and/or an explanation of what types of things cause Application 500 Errors in mongrel.

Hello. I'm moving from a very old Fedora Core 1 to CentOS 4.4, what a change!! Three year ago, I wrote some script (network related) and worked very well. Now, I can put into init.d by means of chkconfig and I restarted the system, but always hang when executing my srcipt (in my new centos 4.4). There a manual for making scripts for init.d? there is some new requirement by which it does not
