The problem is that both computers return hostname = localhost, so that won't
work. IP address is not always possible, as the network might not be up,
especially on the laptop.
How would I check the HWaddress (MAC)?
As ifconfig returns a whole list of things:
1.How can I isolate just 00:xx:xx:xx:xx:xx in order to make a comparision?
2.How do I make this comparison in bash? I guess this value must be a string?
Wrong approach (that means I don't know how to do it reliably).
Try this instead, it needs to be run as root:
#!/bin/bash
# get the root device
rt_dev=$(df / | sed -n '2s/ .*//p'
# get the UUID in a shell variable
fsid=$(dumpe2fs -h $rt_dev | sed -n '/UUID:/s/.*: *//p')
# now you can test it against one or more systems
# if they NFS mount their root like dickless workstations
# you have to test something else like /tmp
