icinga

building a large scaled monitoring system for a customer with icinga 1.4.0 + pnp4nagios 0.6 (bulk mode with npcd), db logging. it will monitor very different stuff …. from servers to network, from esx(i) to linux machines, from firewalls to printers … good to see that all the needed software comes from the debian stable repositories (non-free). once again debian FTW !

vmware / centos 5 network settings

copied vm centos 5 machines with fixed ip settings to a different esxi server. put the machines in a vm net with an active dhcp server. the centos machines switched at boot-time to dhcp and automatically disabled the fixed ip settings. centos creates a new interface configuration file with dhcp settings. the old config file is backed. why ? the mac adress has changed ! (vmware moving). to prevent this you should probably configure the mac adresses from the old esxi system or adjust the network cfg files on centos.

new virtualization project

i`m planning a new virtualization structure for a customer. this time based on three ibm x3650 m3 machines; one machine as iSCSI target, the other two machines with vmware ESXi 4.1, for sure it will be real fun to configure one x3650 m3 as a iSCSI target – hoping debian stable will install clean without patching the kernel for raid modules or something ….  🙂
