BNU files with direct connection in the remote system files

Edit online

These files contain telephone connection entries on the remote system hera.

Systems file: The Systems file on system hera contains the following entry for system zeus:
```
zeus Any zeus 1200 - "" \r\d\r\d\r in:--in: uhera word: portent
```
This entry specifies that system hera can log in to system zeus at any time, by using a direct connection, which is specified in the Devices files. To find the entry in the Devices files, BNU uses the third and fourth fields of the Systems entry. Thus, BNU looks for an entry in the Devices files with the Type field of value zeus and a Class field of value 1200. System hera logs in to system zeus as user uhera with the password portent.
Devices file: The Devices file on system hera contains the following entry for communications with the system zeus:
```
zeus    tty1  -  1200  direct
```
This entry specifies that system hera uses device tty1 at 1200 bps to communicate with system zeus. Because the Dialer is specified as direct, BNU checks the Dialers files for a direct entry.
Dialers file: The Dialers file on system hera contains the following entry for direct connections:
```
direct
```
This entry specifies that no dialer configuration is required on the direct connection.
Permissions file: The Permissions file on system hera contains the following entries, which specify the ways in which zeus can conduct uucico and uuxqt transactions with system hera:
```
LOGNAME=uzeus REQUEST=yes SENDFILES=yes READ=/ WRITE=/
MACHINE=hera:zeus VALIDATE=uzeus REQUEST=yes COMMANDS=ALL READ=/\
WRITE=/
```
These entries specify that system zeus logs in to system hera as uzeus. Because the VALIDATE=uzeus parameter is included, system zeus cannot log in to system hera with any other login ID, nor can any other remote system use the uzeus ID. System zeus can read and write to any directory on system hera, and can send and request files regardless of who initiated the call. System zeus can also initiate any commands on system hera.

Attention: If you provide all the permissions in the preceding example, it is equivalent to giving any user on the remote system a login ID on the local system. Such liberal permissions can jeopardize your security and are given only to remote systems at the same site.
