Description: - STEP 1. I got a different output:

[student@workstation ~]$ lab network-fix setup

Setting up serverb for lab exercise work:

Setting up servera for lab exercise work:

. Backing up network configuration............................ SUCCESS
. Performing network breakage................................. SUCCESS
. Restarting active network................................... SUCCESS

[student@workstation ~]$ ssh root@servera
Last login: Wed Mar 2 23:45:50 2016 from 172.25.250.250

[root@servera ~]# ping6 serverb.lab.example.com
connect: Network is unreachable

• STEP 2.3: My log messages do not correspond to that shown in the practice.

[root@servera ~]# grep enp2s0 /var/log/messages

• STEP 7: I got different output:

Here are the contents of the relevant files:

[root@servera ~]# grep ^hosts /etc/nsswitch.conf

[root@servera ~]# grep serverb /etc/hosts

• STEP 7.2: host commands in <screen> tags both have trailing 'j'

• STEP 8: Second command needs to be in <userinput> tag.

• STEP 9: I got different output:

[root@servera ~]# ping6 serverb.lab.example.com
