NAME
uucpd - UUCP over TCP/IP server daemon
SYNOPSIS
/usr/sbin/uucpd
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 connec-
tion 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 user-
name.
2) If the username refers to an account without a password, the server then prompts with "Pass-
word:". The
uucico process at the other end must supply the password for that account.
The connection is dropped if one or more of the following conditions occurs:
• The username is not valid.
• The username is valid but refers to an account that does not have
/usr/lbin/uucp/uucico
as its login shell.
• The password authentication fails due to an incorrect password to that account.
• The password authentication fails due to the settings in
/etc/default/security. Refer to
the security (4) manpage for detailed information on configurable parameters that affect the pass-
word authentication.
If the 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 the "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 conditions are true :
• The login account is locked (several causes).
• The current time does not match existing time-of-day restrictions for this account.
Under such conditions, uucpd will return the message login incorrect to the connection. The con-
nection is then dropped.
HP-UX 11i Version 3 is the last release to support trusted systems functionality.
