in.uucpd, uucpd - UUCP server


/usr/sbin/in.uucpd [ -n ]


in.uucpd is the server for supporting UUCP connections over networks. in.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) and executes the follow- ing protocol. See services(4): 1. The server prompts with login:. The uucico(1M) process at the other end must supply a username. 2. Unless the username refers to an account without a pass- word, 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. Unless the -n flag is specified, entries are made in /var/adm/utmpx, /var/adm/wtmpx, and /var/adm/lastlog for the username. in.uucpd must be invoked by a user with appropriate privilege (usually root) in order to be able to verify that the password is correct.


in.uucpd uses pam(3PAM) for authentication, account manage- ment, and session management. The PAM configuration policy, listed through /etc/pam.conf, specifies the modules to be used for in.uucpd. Here is a partial pam.conf file with entries for uucp using the UNIX authentication, account management, and session management module. uucp auth required /usr/lib/security/ uucp account required /usr/lib/security/ uucp session required /usr/lib/security/ If there are no entries for the uucp service, then the entries for the "other" service will be used. If multiple SunOS 5.8 Last change: 10 Nov 1998 1 Maintenance Commands in.uucpd(1M) authentication modules are listed, then the peer may be prompted for multiple passwords.
