Re: HMC RMC IPv4?

In a PC I set up for console in a V7.3 machine had both, IPv4 and IPv6. 
The system choose IPv6, even after I suggested an IPv4 address as I read
in the manual.

It is very likely that your best option is to enable IPv6,  and start
using it as "Dual Stack" to start moving to IPv6.  Remember, there are
still lot of IPv4 uses (more than 70%), but IPv4 is a "dead protocol",
it will not be enhanced any more, and its user base is shrinking.

From netstat on the HMC it looks like it's only listening for IPv6 RMC
connections:

$ netstat -tuln | grep 657
tcp6 0 0 :::657 :::* LISTEN
udp6 0 0 :::657 :::*

Since we don't use IPv6, I tried disabling IPv6 on our HMC with:

$ chhmc -c network -s disable --ipv6

After a reboot lshmc -n shows no IPv6 addresses configured, but netstat
still shows RMC only listening for IPv6 connections.
