在安装tcpwrappers-7.6后进行配置,但下文中所提的三个文件一个都没有发现,怎么回事?
/etc/hosts.allow, /etc/hosts.deny,
File protections: the wrapper, all files used by the wrapper, and all directories in the path leading to those files, should be accessible but not writable for unprivileged users (mode 755 or mode 555). Do not install the wrapper set-uid.
Then perform the following edits on the /etc/inetd.conf configuration file :
finger stream tcp nowait nobody /usr/sbin/in.fingerd in.fingerd
becomes:
finger stream tcp nowait nobody /usr/sbin/tcpd in.fingerd |
