SX.25 provides a mechanism for using the standard UNIX uucp, cu, and associated commands over the PAD program by using the xty device driver. The xty device behaves like a tty device that supports both blocking and non-blocking opens of the same logical device. It can support gettys for incoming calls that make a blocking open on the xty device.
This chapter provides information on these UUCP topics:
SX.25 supports a STREAMS interface called the XYT_OUT system, which uses the xty STREAMS module only for outgoing uucp/cu calls. This type of system does not require getty processes. Incoming calls are handled directly by the PAD daemon that executes the login process.
A number of files need modification before uucp/cu type calls can be made over the xty driver. These files and their uses are described below. All these files can be found in the directory /usr/lib/uucp. For detailed information on individual files, refer to IRIX Admin: Networking and Mail.
Specifies which xty devices are available for outgoing calls.
Specifies a number of host-to-SX.25 address mappings.
Specifies permissions that remote users have when sending files, whether local users can request files, and which commands users are allowed to use.
Specifies the command that uucp issues to the pad program to make a uucp call.
Specifies the hosts that uucp knows about. It includes login names and character sequences that uucp is to send and expects to receive as responses.
These files would have the format presented below for a typical UUCP-over-X.25 configuration.
Pad xty80 - 9600 pad Pad xty81 - 9600 pad Pad xty82 - 9600 pad Pad xty83 - 9600 pad
hostname1 A.1234567891 hostname2 A.1234567892
MACHINE=hostname1:hostname2 \ REQUEST=yes \ SENDFILES=yes \ READ=/ WRITE=/ \ COMMANDS=ALL LOGNAME=nuucp \ REQUEST=yes \ SENDFILES=yes \ READ=/ WRITE=/ \ COMMANDS=ALL
|Note: These permissions let users do almost anything, so you may need to be more restrictive. For more detail, refer to IRIX Admin: Networking and Mail.|
