I have just installed a fresh install of Ubuntu 16.04 on
br16p05.aus.stglabs.ibm.com and followed the setup from the WIKI to use
"eth0" as its network access.  I completed the install and it was
working as desired.

I then added two adapters to the partitions' configuration using the HMC
GUI under I/O to add "As Desired" to the partition, a Mason adapter at
location FHZ0145-P2-C6 and a Travis_EN adapter at location
CSS00HL-P1-C5.  I then rebooted the partition to activate both adapters
in prep for an attempt at two TER completions.

I attempted to run "build_net help" to set up the network but when I ran
the command, it appeared to hang.  I exited the instance and checked the
state of the network access by running the command "mount
iofnim.aus.stglabs.ibm.com:/nim/build_net /root/test -o nolock" to make
sure the test/tools directory was mounted. The command returned:

(0) root @ br16p05: /root
# mount iofnim.aus.stglabs.ibm.com:/nim/build_net /root/test -o nolock
mount.nfs: Failed to resolve server iofnim.aus.stglabs.ibm.com: Temporary 
failure in name resolution

I then checked the /etc/network/interfaces file I had modified for
network access for the Ubuntu 16.04 according to the WIKI via .ISO and
it is set up as it was when I originally set up the fresh install.
Thinking the interface may have an issue, I ran "ifdown eth0" and it
returned:

(0) root @ br16p05: /root
# ifdown eth0
ifdown: interface eth0 not configured

To double-check there is more at play here, I also ran "ifup eth0" just
to see what it returned:

(0) root @ br16p05: /root
# ifup eth0
Cannot find device "eth0"
Failed to bring up eth0.

As the setup for eth0 DOES exist in /etc/network/interfaces, I ran
"ifconfig -a" to view the existing interfaces and it returned this:

(0) root @ br16p05: /root
# ifconfig -a

As the first four interfaces appear in the naming convention for past
instances of network adapters in Linux, the only one left (with the
exception of "lo" is "ibmveth2" which is not set up either but appears
to show a similar issue of the original defect where the name "eth0" is
being replaced by something else that is subsequently not set up.

I will attempt to modify /etc/network/interfaces for "ibmveth2" after
copying the original interfaces file to /etc/network/interfaces.old,
reboot the partition and see if that will allow network access in case a
developer would like to look at the fresh install overnight.

NOTE: The modification to set up "ibmveth2" in /etc/network/interfaces
appeared to work after rebooting the partition but I am unable to ssh or
telnet into the partition from an LCB as I get these returns:

$ ssh [email protected]
[email protected]'s password:
Received disconnect from 9.3.137.40: 2: Invalid ssh2 packet type: 192

$ telnet 9.3.137.40
Trying 9.3.137.40...
telnet: connect to address 9.3.137.40: Connection refused

Please advise.
