Universal Command Server for IBM i

The following set of rules permit services for the subnet 10.20.30 and denies all other connections unless an X.509 certificate is presented that maps to certificate ID operations.

ucmd_access     10.20.30.,*,*,allow,auth
ucmd_access     ALL,*,*,deny,auth

ucmd_cert_access  operations,*,allow,auth
ucmd_cert_access  *,*,deny,auth

When no certificate is presented that maps to a certificate ID, the following set of rules effectively permit connections from any host, but has limited access from host 10.20.30.40 to user TS1004 on that host.

• No host can execute commands as local user root.
• User TS1004 on host 10.20.30.40 can execute commands as local user tsup1004 without providing the password.
• Users TS1004 from host 10.20.30.40 can execute commands as any local user by providing the local user password.

When a certificate is presented that maps to a certificate ID, certificate ID joe can request local user ID tsup1004 without a password.

• Certificate ID joe is allowed to execute commands with any other local user ID with a password.
• Certificate ID operations cannot run anything.
• All other certificate IDs can execute commands with any user ID except for root with a password.
