No, "spawn" is part of the syntax for the /etc/hosts.deny (and .allow) configuration file, which is used by the TCP wrappers library and the tcpd program. It's described in the hosts_options(5) manual page: # spawn shell_command # Execute, in a child process, the specified shell # command, after performing the %<letter> expansions ... There's also a "twist", which connects the child process to the network connection (so if you run "echo" via "twist", the text is sent to the other end of the connection). Also, please note that TCP wrappers logs both allowed and denied connections to syslog, so if you only want the stuff in a log, you don't need to execute special commands. You can set the log priority (info, notice, critical, etc.) via the "severity" option, also described on the hosts_options(5) manual page. -- -=- Rjs -=- [EMAIL PROTECTED]
