About Host wildcard validation for universal share creation

NetBackup uses the following set of rules to validate wildcard characters that are used in the Host that you specify when you create a universal share.

Host name or fully qualified domain name (FQDN) validation rules:

  • Allow a single host name or FQDN.

  • Allow '*' and '?' wildcards only for FQDNs.

    Do not allow any other wildcard.

  • Validate the host name or FQDN validated according to the RFC standard. Refer to this resource for more information:

    https://en.wikipedia.org/wiki/Hostname

IP address or IP Network/Range validation rules:

  • Allow a single host where one particular host is specified with an IP address.

  • Allow '/' only with IP address range. For example: 192.168.0.0/28. allows the first 16 IP addresses, from 192.168.0.0 to 192.168.0.15, to access the exported file system, but not 192.168.0.16 and higher.

    Do not allow any other wildcard or special character.

  • Validate IP address, IP range, and FQDNs using regex or library functions.

The following examples are valid Host entries that use wildcards:

*.example.com

..example.com

*.vxindia.veritas.com

*.veritas.com

some.example.com

*.some.example.com

s???me.example.com

s?me.example.com

*.example.com

*.veritas.com

*.example.com

..example.com

*.vxindia.veritas.com

*.veritas.com

The following examples are not valid:

so*me.example.com/

s?me.examp!e.com/

s*me.examp!!!!e.com

so*me.example.com/

s?me.examp!e.com/

s*me.examp!!!!e.com

some.example.com?

some.example.com*

some.example.com?

some.example.com*

some.ex*ample.com

s*ome.example.com

s*me.example.com
