Network security files

IBM® Informix® products follow standard security procedures that are governed by information contained in the network security files.

For a client application to connect to a database server on a remote computer, the user of the client application must have a valid user ID on the remote computer.

Trusted-host information
Users on trusted hosts are allowed to access the local system without supplying a password. You can include an optional user name to limit the authentication to a specific user on a specific host.
Trusted-user information
A user can list hosts from which they can connect as a trusted user in their .rhosts file.
The netrc information
The netrc information is optional information that specifies identity data. A user who does not have authorization to access the database server or is not on a computer that is trusted by the database server can use this file to supply a name and password that are trusted. A user who has a different user account and password on a remote computer can also provide this information.
