"connectivity" could mean several things, representing several layers.
The simplest, most fundamental, is 'ping <hostname>' That will send a packet from the client to <hostname>. If a response is received, you've got basic network connectivity.

No connectivity (vbdb112-01 is down at the moment)
ed@ed-Gazelle-00:~$ ping vbdb112-01
PING vbdb112-01 (192.168.56.102) 56(84) bytes of data.
From ed-Gazelle-00 (192.168.56.1) icmp_seq=1 Destination Host Unreachable
From ed-Gazelle-00 (192.168.56.1) icmp_seq=2 Destination Host Unreachable

Connectivity (vbdb112-01 is now up)
ed@ed-Gazelle-00:~$ ping vbdb112-01
PING vbdb112-01 (192.168.56.102) 56(84) bytes of data.
64 bytes from vbdb112-01 (192.168.56.102): icmp_seq=1 ttl=64 time=0.667 ms
64 bytes from vbdb112-01 (192.168.56.102): icmp_seq=2 ttl=64 time=0.367 ms
