3. Test connectivity by pinging the network connections. At the prompt, enter ping hostname.
For example, to ping Server B, enter ping server_b. Output similar to the following is
displayed:
64 bytes from server_b (10.10.2.145): icmp_seq=0 ttl=64 time=0.053 ms
64 bytes from server_b (10.10.2.145): icmp_seq=1 ttl=64 time=0.053 ms
64 bytes from server_b (10.10.2.145): icmp_seq=2 ttl=64 time=0.053 ms
64 bytes from server_b (10.10.2.145): icmp_seq=3 ttl=64 time=0.053 ms
Press CTRL-C to stop the ping process.
If you receive a timeout error, check cabling or contact a network administrator for
assistance. If you receive an unknown host error, check the /etc/hosts file and make sure
everything is correct. Note that the hostnames in this file are case-sensitive.
4. Set up and authorize secure shell (SSH) if you are configuring VTS for AutoCopy or if you wish
to secure communication for Instant DR.
a. At the command prompt, become bill:
su - bill
b. Generate an authorization key for SSH for the secondary server, to authorize remote
access for the bill user:
ssh-keygen -t rsa
c. Press ENTER to save the file in the default location. This step creates the
/home/bill/.ssh/ directory.
d. Press ENTER to skip the pass phrase.
e. Press ENTER to verify skipping the pass phrase.
f. Copy the generated authorization key to the secondary server (Server B):
ssh-copy-id –i /home/bill/.ssh/id_rsa.pub bill@server_b
g. When prompted, enter yes.
h. Enter the password for the bill user at the secondary server.
Note If problems arise when using SSH with the secondary server, you can remove the
/home/bill/.ssh/known_hosts and /home/bill/.ssh/authorized_keys files from the
secondary and primary servers and repeat the steps above.
