uucpd(1M)

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:

      1) The server prompts with "login:", the uucico
     process at the other end must supply a username.
      2) 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.
