hosts_ctl.c

基于TCP-WRAP原理的系统监控的c语言实现代码

 /*
  * hosts_ctl() combines common applications of the host access control
  * library routines. It bundles its arguments then calls the hosts_access()
  * access control checker. The host name and user name arguments should be
  * empty strings, STRING_UNKNOWN or real data. If a match is found, the
  * optional shell command is executed.
  * 
  * Restriction: this interface does not pass enough information to support
  * selective remote username lookups or selective hostname double checks.
  *
