CFALIAS Parameters

You have to define some CFALIAS parameters to restrict a user's ability to define a file on your mainframe.

See the following table for the available CFALIAS parameters.

Parameter	Description
`USERID`	Defines the user ID that is associated with the file transfer. This parameter can be used along with the `NODE` or `IPADDR` parameters to further qualify the CFALIAS matching scan. Note: If the `NODE` and `IPADDR` parameters are not defined, then this parameter must be defined. You can specify a special user ID called `DEFAULT`. With this setting, CFALIAS scanning detects a match for the user ID in this CFALIAS configuration entry. If this parameter is not entered, no checking is performed on the user ID for this entry.
`NODE`	Defines the node that is associated with the file transfer. Nodes are defined within the Platform Server CONFIG DD statement. This parameter can be used along with the `USERID` parameter to further qualify the CFALIAS matching scan. Note: If the `USERID` and `IPADDR` parameters are not defined, then this parameter must be defined. This parameter is mutually exclusive with the `IPADDR` parameter. You can specify a special node called `DEFAULT`. With this setting, CFALIAS scanning detects a match for the node in this CFALIAS configuration entry. If this parameter is not entered, no checking is performed on the node for this entry.
`IPADDR`	Defines the IP address that is associated with the file transfer. This parameter can be used along with the `USERID` parameter to further qualify the CFALIAS matching scan. Note: If the `USERID` and `NODE` parameters are not defined, then this parameter must be defined. This parameter is mutually exclusive with the `NODE` parameter. If this parameter is not entered, no checking is performed on the IP address for this entry.
`TYPE`	Defines whether the processing is for send or receive requests. This parameter is relative to the Platform Server for z/OS. Valid values are: `SEND`: An entry is only matched if the Platform Server is sending a file. `RECEIVE`: An entry is only matched if the Platform Server is receiving a file. `BOTH`: An entry is matched if the Platform Server is sending or receiving a file.
`FILE`	Defines the actual file name on the z/OS system. The file name is translated to upper case unless the file is an HFS file. When specified, both `FILE` and `ALIAS` must be defined. Note: `FILE` and `ALIAS` are mutually exclusive with the ALLOW parameter.
`ALIAS`	Defines the file name that the user sends. This file name is translated to upper case, and is therefore not case sensitive. When specified, both `FILE` and `ALIAS` must be defined. Note: `FILE` and `ALIAS` are mutually exclusive with the ALLOW parameter.
`ALLOW`	Defines whether the user is authorized to execute certain functions. Valid values are: `YES`: The user is authorized to use an actual file name in a file transfer request. CFALIAS processing is not performed for this `USERID` and `NODE/IPADDR` combination. `NO`: The user is not authorized to perform file transfer operations. The file transfer request for this `USERID` and `NODE/IPADDR` combination is rejected. Note: This parameter is mutually exclusive with the `FILE` and `ALIAS` parameters.
