------------------------------------------------------------------------
| Parameter : gw/reg_info |
------------------------------------------------------------------------
------------------------------------------------------------------------
| Short Description : External security filename for gateway |
------------------------------------------------------------------------
------------------------------------------------------------------------
| Parameter Description : |
| ----------------------- |
| You can use this parameter to protect the registration of external |
| programs. |
| You can avoid the unauthorized registration of programs by |
| maintaining the file reginfo in the data directory of the gateway |
| instance. |
| If the file exists, the system searches for valid entries for the |
| registration here. It also searches, as previously, in the |
| %%gw/sec_info%% files. |
| |
| You can define the entries better than previously by using the |
| reginfo file. |
| |
| Entries in this file have the following syntax: |
| |
| TP=<tp> [HOST=<hostname>] [NO=<n>] [ACCESS=<hostname,...&
| [CANCEL=<hostname,...>] |
| |
| You can use a corresponding row to allow specific programs to |
| register themselves from another host. |
| |
| Valid TP names: |
| |
| No restriction : * |
| TP names : foo |
| Start of name : foo* |
| |
| Valid host names: |
| |
| No restriction : * |
| Host name : such as sapprod |
| IP address : 192.1.1.3 |
| Domain : *.sap.com |
| Subnetwork addresses: 192.1.1.* |
| |
| Examples of valid entries: |
| |
| TP=* All registrations allowed |
| HOST=* TP=foo* All registrations that begin with foo, |
| but not f or fo, are allowed |
| HOST=*.sap.com TP=* All registrations from the domain *.sap.com |
| are allowed |
| |
| If the TP name was specified without wild cards, you can also |
| specify the number of permissible registrations. |
| |
| Example: |
| HOST=* TP=foo NO=1 , that is, only one program with the name foo |
| can register, all other attempts to register by a program with |
| this name are rejected. |
| |
| You can also define an access list for each entry, to control |
| access to the registered programs from the client side. An access |
| list is a name of host names that must conform to the above rules. |
| However, "*" is not allowed here. If no access list is specified, |
| the program can be used from any client. The local gateway, with |
| which the program is registered, always has access. |
| |
| |
| |
| It is important to note that this is a check based on hosts, and |
| not at user level, such as: |
| HOST=* TP=foo ACCESS=*.sap.com |
| |
| The program foo can only be accessed by hosts from the domain |
| *.sap.com. Accesses from another domain are rejected. |
| |
| You can use the CANCEL list to define whether other clients may |
| end the registered program. The same rules apply for this list as |
| for HOST or ACCESS, such as: |
| HOST=* TP=foo ACCESS=*.sap.com CANCEL=*.wdf.sap.corp |
| |
| The program foo can only be ended by clients that have logged on |
| from the domain wdf.sap.corp. |
