Basic Rocks linux stuff.

Some basic Rocks Linux Cluster stuff... just some stuff I need to remember and always forget:

list all host interfaces:


rocks list host interface

changing the mac address of a network card: 


rocks set host interface mac HOSTNAME iface=eth1 mac=00:00:00:00:00:02



please be a aware that you also have to remove the mac address definition in the following file:


/etc/sysconfig/networking/devices/ifcfg-eth*


you should be able to just uncomment the mac address line, without any ill effects and this will simplify this process next time.


and possible in the dhcpd.conf file


vim /etc/dhcpd.conf


in case you modify the eth0 interface. To ensure that the dhcpd configuration still works as supposed to.
