Sometimes I get a stuck or repeating task that prevent’s operations. This seams to clear it up almost every time:
service mgmt-vmware restart
service vmware-vpxa restart
A friend at work showed me this:
You can add additional IP addresses to your interface.
edit /etc/sysconfig/network-scripts/ifcfg-eth0:1
My origonal nic is eth0, subinterface is eth0:1
DEVICE=eth0:1
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.2
NETMASK=255.255.255.0
BROADCAST=192.168.1.255
NETWORK=192.168.1.0
HWADDR=00:15:58:73:d8:a9
Then bring up the new interface.
A friend at work showed me this trick. It’s usefull if you change network cards and need your old MAC address.
ifconfig eth0 hw ether 00:00:00:00:00:00
I was wiping a drive today and didn’t much care for the way dd doesn’t show anything until it’s complete.
I found this:
dd if=/dev/zero of=/dev/hda & watch -n5 -- pkill -USR1 ^dd$
–edit–
A reader posted this, but I accedentally marked him as spam.
dd if=/dev/zero of=/dev/hda & pid=$! && while kill -USR1 $pid; do sleep 15; done
