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 +命令解释器的初始化脚本也可能执行。请参考手册中相应的章节来获取关于此功能的更多信息。 +.PP +在登录 shell 中以第一个字符是\(lq*\(rq标注的是子系统登录。给定的主目录将被用于用户实际登录的新文件系统的根。 +.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 "选项" +.PP +\fB\-f\fR +.RS 4 +不要执行认证，用户已经预认证过。 +.sp +Note: In that case, +\fIusername\fR +is mandatory\&. +.RE +.PP +\fB\-h\fR +.RS 4 +此登录的远程主机名。 +.RE +.PP +\fB\-p\fR +.RS 4 +保留环境。 +.RE +.PP +\fB\-r\fR +.RS 4 +为 rlogin (远程登录)执行 autologin (自动登录)协议。 +.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 "CAVEATS" +.PP +This version of +\fBlogin\fR +has many compilation options, only some of which may be in use at any particular site\&. +.PP +文件的位置由系统配置决定。 +.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 "配置文件" +.PP +The following configuration variables in +/etc/login\&.defs +change the behavior of this tool: +.SH "文件" +.PP +/var/run/utmp +.RS 4 +当前登录会话的列表。 +.RE +.PP +/var/log/wtmp +.RS 4 +先前的登录会话列表。 +.RE +.PP +/etc/passwd +.RS 4 +用户账户信息。 +.RE +.PP +/etc/shadow +.RS 4 +安全用户账户信息。 +.RE +.PP +/etc/motd +.RS 4 +System message of the day file\&. +.RE +.PP +/etc/nologin +.RS 4 +阻止非 root 用户登录。 +.RE +.PP +/etc/ttytype +.RS 4 +终端类型列表。 +.RE +.PP +$HOME/\&.hushlogin +.RS 4 +阻止显示系统信息。 +.RE +.PP +/etc/login\&.defs +.RS 4 +Shadow 密码套件配置。 +.RE +.SH "参见" +.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)\&. |
