NAME
/usr/sbin/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(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 if the password is not the correct password for that
account, the connection is dropped. Otherwise,
uucico(1M)
is run. Entries are made in
/var/adm/wtmp
traceable with
who(1)
and
last(1M).
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.
WARNINGS
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.
