______________________________________________________________________
Check if a list requirements regarding processes and network
connections do exist.
The check returns OK if all given requirements match.
SYNTAX:
$(basename $0) [-h] [PARAMETERS]
OPTIONS:
-h or --help show this help.
-v or --verbose show more data: processes and port numbers from
/etc/services; add it as first param
PARAMETERS:
-c|--connect TYPE TARGET PORT
check if connect to a server to a given port
is reachable
TYPE string one of tcp|udp
TARGET string target host
PORT int port number
-p|--process STRING check if a process with given regex exists
-t|--tcp PORT check if connect on local tcp port is reachable;
This is a shortcut for -c tcp localhost [port]
The parameters can be repeated multiple times. Checks will be executed in
the given order.
EXAMPLE
$(basename $0) -p httpd -p mysqld -t 22 -t 80 -t 443 -t 3306
Check if
- a process httpd and a process mysqld exist
- localhost listens to ports 22, 80, 443 and 3306
