  • If that's not possible using the socket feature newer versions of bash support
  • And only if nothing of these is useable resort to telnet

Example of how easy it's with netcat/nc:
Code:
for port in {1000..1050}; do nc -z -w 3 1.2.3.4 $port && echo "Port $port open" || echo "Port $port closed"; done


My server is a production server and I can't installing anything, for I am not the admin and it requires approvals.

Would someone help me with the correct netstat script to figure which ports are connecting and which are not.

NAME
net-server - Base Net::Server starting module SYNOPSIS
net-server [base type] [net server arguments] net-server PreFork ipv '*' net-server HTTP net-server HTTP app foo.cgi net-server HTTP app foo.cgi app /=bar.cgi net-server HTTP port 8080 port 8443/ssl ipv '*' server_type PreFork --SSL_key_file=my.key --SSL_cert_file=my.crt access_log_file STDERR DESCRIPTION
The net-server program gives a simple way to test out code and try port connection parameters. Though the running server can be robust enough for full tim use, it is anticipated that this binary will just be used for basic testing of net-server ports, acting as a simple echo server, or for running development scripts as CGI. OPTIONS
"base type" The very first argument may be a Net::Server flavor. This is given as shorthand for writing out server_type "ServerFlavor". Additionally, this allows types such as HTTP and PSGI, which are not true Net::Server base types, to subclass other server types via an additional server_type argument. net-server PreFork net-server HTTP # becomes a HTTP server in the Fork flavor net-server HTTP server_type PreFork # preforking HTTP server "port" Port to bind upon. Default is 80 if running a HTTP server as root, 8080 if running a HTTP server as non-root, or 20203 otherwise. Multiple value can be given for binding to multiple ports. All of the methods for specifying port attributes enumerated in Net::Server and Net::Server::Proto are available here. net-server port 20201 net-server port 20202 net-server port 20203/IPv6 "host" Host to bind to. Default is *. Will bind to an IPv4 socket if an IPv4 address is given. Will bind to an IPv6 socket if an IPv6 address is given (requires installation of IO::Socket::INET6). If a hostname is given and "ipv" is still set to 4, an IPv4 socket will be created. If a hostname is given and "ipv" is set to 6, an IPv6 socket will be created. If a hostname is given and "ipv" is set to * (default), a lookup will be performed and any available IPv4 or IPv6 addresses will be bound. The "ipv" parameter can be set directly, or passed along in the port, or additionally can be passed as part of the hostname. net-server host localhost net-server host localhost/IPv4 There are many more options available.
