Edit share access control

Edit online

System administrators can provide a list of authorized systems.

Enter the Authorized System per the rules. A blank list implies all systems can access the share. A non-empty list implies only the systems that are listed in the text box can access the share. Enter the wanted systems and click Update to save or Cancel.

The Manager application validates each authorized system in the list. An authorized system must be one of the following items.

- An IPv4 address.
- A classless inter-domain routing string. Example - 192.168.56.101/24.
- An IPV4 address with a subnet address. Example - 192.168.56.101/255.255.255.0.
- A fully qualified domain name. Example - usil.ibm.com.
- A string equal to "*". A '*' implies any system can access the share.
- A '*' in a domain names. A name with a '*' is matched as a Posix basic regular expression. Example - *.ibm.com. Note - *.ibm.com matches usil.ibm.com or host1.usil.com.
- One or more '?' in the domain name. A domain name with one or more '?' is also matched as a Posix basic regular expression. Example - usil?.ibm.com matches usi.ibm.com or usil.ibm.com.
- Character Classes ([..]) in domain names. Example - [abc]-host.ibm.com. It matches a-host.ibm.com or b-host.ibm.com or c-host.ibm.com.
- '*' or '?' or '[]' can be present in the same domain name multiple times.
Attention: If an entry in the list contains '?', '*', or '[', the Manager application makes sure that the authorized system string is a valid regular expression. It is so that entries such as *.ibm.com, host?.ibm.com, and host[1-9].ibm.com can be entered.
  • Wildcards are not supported in IP/subnet addresses.
  • Each entry must be 1 - 253 characters.
  • Each share can have 1000 (max) authorized systems.
  • Entries are case-insensitive.
