NAME
uucpd — UUCP over TCP/IP server daemon
DESCRIPTION
uucpd
is the server for supporting UUCP connections over TCP/IP networks.
uucpd
is invoked by
inetd
(see
inetd(1M))
when a UUCP connection is established (that is, a connection to the port
indicated in the "uucp" service specification; see
services(4)),
and executes the following protocol:
The server prompts with "login:", the
uucico
process at the other end must supply a username.
Unless the username refers to an account without a
password, the server then prompts with "Password:", the
uucico
process at the other end must supply the password
for that account.
If the username is not valid or is valid but refers to an account that does not
have
/usr/lbin/uucp/uucico
as its login shell, or when password authentication fails due to an incorrect
password to that account or due to the settings
in
/etc/default/security,
connection is dropped.
Refer to the
security(4)
manual page for detailed information on configurable parameters that affect the
behavior of this command. If connection is successful,
uucico
is run
(see
uucico(1M)).
Entries are made in
/var/adm/wtmps
traceable with
the
who
and
last
commands (see
who(1)
and
last(1)).
Protocol Restriction
Only 'g' protocol for
uucico
is supported.
DIAGNOSTICS
All diagnostic messages are returned on the connection, after which the
connection is closed.
- user read
An error occurred while reading the username.
- passwd read
An error occurred while reading the password.
- login incorrect
The username or the password is invalid or the user's login
shell for this account is not
/usr/lbin/uucp/uucico.
On Trusted Systems
uucpd
prohibits
uucico
to start if any of the
following are true :
the login account is locked (several causes).
current time doesn't match existing time-of-day restrictions
for this account.
Under such conditions
uucpd
will return the message
login incorrect
to the connection. The connection is then dropped.
