It is normally invoked automatically by responding to the +\fIlogin:\fR +prompt on the user\*(Aqs terminal\&. +\fBlogin\fR +may be special to the shell and may not be invoked as a sub\-process\&. When called from a shell, +\fBlogin\fR +should be executed as +\fBexec login\fR +which will cause the user to exit from the current shell (and thus will prevent the new logged in user to return to the session of the caller)\&. Attempting to execute +\fBlogin\fR +from any shell but the login shell will produce an error message\&. +.PP +The user is then prompted for a password, where appropriate\&. Echoing is disabled to prevent revealing the password\&. Only a small number of password failures are permitted before +\fBlogin\fR +exits and the communications link is severed\&. +.PP +If password aging has been enabled for your account, you may be prompted for a new password before proceeding\&. You will be forced to provide your old password and the new password before continuing\&. Please refer to +\fBpasswd\fR(1) +for more information\&. +.PP +After a successful login, you will be informed of any system messages and the presence of mail\&. You may turn off the printing of the system message file, +/etc/motd, by creating a zero\-length file +\&.hushlogin +in your login directory\&. The mail message will be one of "\fIYou have new mail\&.\fR", "\fIYou have mail\&.\fR", or "\fINo Mail\&.\fR" according to the condition of your mailbox\&. +.PP +Your user and group ID will be set according to their values in the +/etc/passwd +file\&. The value for +\fB$HOME\fR, +\fB$SHELL\fR, +\fB$PATH\fR, +\fB$LOGNAME\fR, and +\fB$MAIL\fR +are set according to the appropriate fields in the password entry\&. Ulimit, umask and nice values may also be set according to entries in the GECOS field\&. +.PP +On some installations, the environmental variable +\fB$TERM\fR +will be initialized to the terminal type on your tty line, as specified in +/etc/ttytype\&. +.PP +Pu\(`o anche essere eseguito uno script di inizializzazione per il proprio interprete dei comandi\&. Fare riferimento alla relativa sezione di manuale per maggiori informazioni su questa funzione\&. +.PP +Un sottosistema di login \(`e indicato dalla presenza del carattere \(Fo*\(Fc all\*(Aqinizio della shell di login\&. La directory home impostata sar\(`a utilizzata come root di un nuovo file system al quale l\*(Aqutente accede\&. +.PP +The +\fBlogin\fR +program is NOT responsible for removing users from the utmp file\&. It is the responsibility of +\fBgetty\fR(8) +and +\fBinit\fR(8) +to clean up apparent ownership of a terminal session\&. If you use +\fBlogin\fR +from the shell prompt without +\fBexec\fR, the user you use will continue to appear to be logged in even after you log out of the "subsession"\&. +.SH "OPZIONI" +.PP +\fB\-f\fR +.RS 4 +Non effettua l\*(Aqautenticazione, l\*(Aqutente \(`e gi\(`a autenticato +.sp +Note: In that case, +\fIusername\fR +is mandatory\&. +.RE +.PP +\fB\-h\fR +.RS 4 +Nome dell\*(Aqhost remoto per questo login\&. +.RE +.PP +\fB\-p\fR +.RS 4 +Non modifica l\*(Aqambiente\&. +.RE +.PP +\fB\-r\fR +.RS 4 +Attiva il protocollo autologin di rlogin\&. +.RE +.PP +The +\fB\-r\fR, +\fB\-h\fR +and +\fB\-f\fR +options are only used when +\fBlogin\fR +is invoked by root\&. +.SH "AVVISI/CAVEAT" +.PP +This version of +\fBlogin\fR +has many compilation options, only some of which may be in use at any particular site\&. +.PP +La posizione dei file \(`e soggetta a differenze in base alla configurazione del sistema\&. +.PP +The +\fBlogin\fR +program is NOT responsible for removing users from the utmp file\&. It is the responsibility of +\fBgetty\fR(8) +and +\fBinit\fR(8) +to clean up apparent ownership of a terminal session\&. If you use +\fBlogin\fR +from the shell prompt without +\fBexec\fR, the user you use will continue to appear to be logged in even after you log out of the "subsession"\&. +.PP +As with any program, +\fBlogin\fR\*(Aqs appearance can be faked\&. If non\-trusted users have physical access to a machine, an attacker could use this to obtain the password of the next person coming to sit in front of the machine\&. Under Linux, the SAK mechanism can be used by users to initiate a trusted path and prevent this kind of attack\&. +.SH "CONFIGURAZIONE" +.PP +The following configuration variables in +/etc/login\&.defs +change the behavior of this tool: +.SH "FILE" +.PP +/var/run/utmp +.RS 4 +Elenco delle sessioni attive\&. +.RE +.PP +/var/log/wtmp +.RS 4 +Elenco delle precedenti sessioni di login\&. +.RE +.PP +/etc/passwd +.RS 4 +Informazioni sugli account utente\&. +.RE +.PP +/etc/shadow +.RS 4 +Informazioni sicure sugli account utente\&. +.RE +.PP +/etc/motd +.RS 4 +File di sistema con il messaggio del giorno\&. +.RE +.PP +/etc/nologin +.RS 4 +Impedisce l\*(Aqaccesso al sistema per utenti diversi da root\&. +.RE +.PP +/etc/ttytype +.RS 4 +Elenco di tipi di terminale\&. +.RE +.PP +$HOME/\&.hushlogin +.RS 4 +Impedisce che vengano mostrati i messaggi di sistema\&. +.RE +.PP +/etc/login\&.defs +.RS 4 +Configurazione del pacchetto password shadow +.RE +.SH "VEDERE ANCHE" +.PP +\fBmail\fR(1), +\fBpasswd\fR(1), +\fBsh\fR(1), +\fBsu\fR(1), +\fBlogin.defs\fR(5), +\fBnologin\fR(5), +\fBpasswd\fR(5), +\fBsecuretty\fR(5), +\fBgetty\fR(8)\&. |
