telnet of all the possible ways is probably the least useful for this, as you can't set a timeout properly, nor get a meaningful, parseable output. Better would be
Installing nmap
If that's not possible using netcat/nc, installing it if possible
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:
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.
I'm need to connect to another host in a script using the telnet command. How do I pass the login and password to be able to connect to the other host from within the script? (10 Replies)

Hi Guys,
How do I write the script for the following
telnet 192.168.1.100 9002
if the result is less than 1 second. The script should say as port open
if the result takes more than 3 seconds. The script should display as port closed.

Hi all,
I would like to write a ad hoc shell script that would allow me to do some telnet tests to multiple IP's and ports at the same time . So, I want to determine which one is successful and which one fails. So, basically I would like the shell to spawn the telnet test and to break out of... (3 Replies)

NET-SERVER(1) User Contributed Perl Documentation NET-SERVER(1)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. Please see the Net::Server documentation.
