Replibit - Enable Promiscuous Mode

There are times where more than one VM is running on an Appliance and they can not ping each other.  When this happens you will need to enable promiscuous mode

To enable promiscuous mode first open a terminal on the appliance and log in as root. If you do not have the root password, please let me know and I can send it to you. After you in as root run

netstat -i

and you should see that eth0 has a flag of BMRU. Next run

ip link set eth0 promisc on

Now run the netstat -i again and your flag should now be BMPRU.

Flag details are as follows:

B flag is for broadcast
M flag is for multicast
P flag is for promisc mode
R is for running
U is for up

When the DR is over run

ip link set eth0 promisc off

To turn off promiscuous mode. This setting should not be permit and a reboot will clear the flag. You should not have to do this on all Appliances. This issue is from a limitation of the NIC and Switch.

To make it per, add ip link set eth0 promisc on  above the Xeit 0 line in rc.local
