Error message

Cause

On a vanilla machine deployment for Linux, by default ::1 is present in the /etc/hosts file. 
With IPV6 enabled, pinging localhost does not return the required 127.0.0.1 when PowerProtect Data Manager agent communicates with a local REST Server.

A current requirement of the product is that the response to ping localhost should be 127.0.0.1.
In this case, it was sending ::1

Example:

# ping localhost
PING localhost(localhost (::1)) 56 data bytes
64 bytes from localhost (::1): icmp_seq=1 ttl=64 time=0.053 ms
64 bytes from localhost (::1): icmp_seq=2 ttl=64 time=0.042 ms
64 bytes from localhost (::1): icmp_seq=3 ttl=64 time=0.039 ms

 

Resolution

1. Using VI/VIM edit the /etc/hosts file on the destination VM for the restore.
# vi /etc/hosts
2. Comment out the ::1 entry and save the changed file.
Before:
before
After: after change
3. Carry out ping localhost again and you should see 127.0.0.1 returned and not ::1.
expected result
