BNU files for TCP/IP connection entries in the remote system's files

Edit online

These files are on the remote system hera.

  • Systems file: A Systems file on system hera contains the following entry to allow hera to contact system zeus: 
    zeus Any TCP,t - - ogin:--ogin: uhera ord: lightning

    This example specifies that system hera can call system zeus at any time, by using the t protocol for communications with system zeus. System hera logs in to system zeus as user uhera with the password lightning. Again, BNU next checks the Devices files for an entry of type TCP.

    Note: The t protocol supports the TCP. Therefore, always use the t protocol for BNU communications over TCP/IP connections. However, the t protocol cannot be used when the Type field is ACU or when a modem connection is being used.
  • Devices file: The Devices file that is used by the uucico daemon on system hera contains the following entry for TCP/IP connections: 
    TCP  -  -  -  TCP

    Because the device type is TCP, there are no Type, Line, or Line2 entries. The Dialer is also specified as TCP. BNU looks in the Dialers files for a TCP entry.

  • Dialers file: The Dialers file that is used by the uucico daemon on system hera contains a TCP/IP entry as follows: 
    TCP

    This entry specifies that no dialer configuration is required.

    Note: Dialer configuration is never required over a TCP/IP connection.
  • Permissions file: The Permissions file on system hera contains the following entry, which grants system zeus access to system hera: 
    LOGNAME=uzeus SENDFILES=yes REQUEST=yes \
MACHINE=hera:zeus VALIDATE=zeus COMMANDS=rmail:who:uucp

    The combined LOGNAME and MACHINE entries provide the following permissions to system zeus, when system zeus and system hera are connected:

    • System zeus can request and send files regardless of who initiated the call.
    • System zeus can read and write only to the public directory (the default).
    • System zeus can run only the rmail, who, and uucp commands.
    • System zeus must log in to system hera as user uzeus and system zeus cannot use any other login ID for BNU transactions.
      Note: If the permissions are not the same for system hera and system zeus, the LOGNAME and MACHINE entries are as follows: 
      LOGNAME=uzeus VALIDATE=zeus SENDFILES=yes REQUEST=yes
MACHINE=hera:zeus COMMANDS=rmail:who:uucp REQUEST=yes
