Appendix I:
Password File
To allow remote systems to call the local system, password entries must be
made for any uucp logins. For example,
uucp:zaaAA:3:5:UUCP Login Account:/usr/spool/uucppublic:/usr/lib/uucp/uucico
Note that the uucico daemon is used for the shell, and the spool directory is used
as the working directory.
There must also be an entry in the passwd file for a uucp administrative login.
This login is the owner of all the uucp object and spooled data files and is
usually "uucpadm". For example, the following is an entry in /etc/passwd for
this administrative login:
uucpadm:zAvLCKp:8:8:UUCP Administration:/usr/lib/uucp:
Note that the standard shell is used instead of uucico.
Lines File
The file /usr/lib/uucp/L-devices contains the list of all lines that are directly
connected to other systems or are available for calling other systems. The file
contains the attributes of the lines and whether the line is a direct connection or
can call via a dialer. The format of the file is
type line call-device speed protocol
where each field is
type
line
call-device
speed
protocol
The following entries illustrate various types of connections:
Version 1.0
Two keywords are used to describe whether a line is directly
connected to another system (DIR) or uses an automatic calling
unit (ACU)d. An Ethernet/XNS connection would use the DIR
keyword.
This is the device name for the line (e.g., ttyd2 for a direct line,
cu10 for a line connected to an ACU and xns for
Ethernet/XNS).
If the ACU keyword is specified, this field contains the device
name of the ACU. Use xns for Ethemet/XNS. Otherwise, the
field is ignored; however, a placeholder must be used in this
field so that the protocol field can be interpreted.
The line speed that the connection is to run at. Use xns for
Ethernet/XNS.
This is an optional field that needs only be filled in if the
connection is for a protocol other than the default terminal
protocol. Use xns for Ethernet/XNS.
