UUCPD(8C)

NAME
uucpd - UUCP server

SYNOPSIS
/usr/etc/in.uucpd

AVAILABILITY

This command is available with the uucp software installation option. Refer to for information on how to install optional software.

DESCRIPTION

uucpd is the server for supporting UUCP connections over networks.

uucpd is invoked by inetd(8C) when a UUCP connection is established (that is, a connection to the port indicated in the “uucp” service specification; see services(5)), and executes the following protocol:

1)  The server prompts with login:. The uucico(8C) 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/lib/uucp/uucico as its login shell, or if the password is not the correct password for that account, the connection is dropped. Otherwise, uucico is run, with the user ID, group ID, group set, and home directory for that account, with the environment variables USER and LOGNAME set to the specified username, and with a -u flag specifying the username. Entries are made in /var/adm/wtmp and /var/adm/lastlog for the username.

FILES
/var/adm/wtmp
    accounting
/var/adm/lastlog
    time of last login
