One exemple overall: when we start a remote shell using NC with -e option we don’t have a FULL interactive command prompt, but a NON interactive one. Obviously not always it work as we’ll wish. Nowadays there are many Netcat clones, some of these use encryption or implement the remote command execution and the use of passwords you can easely find it googling.
#Netcat windows listen udp how to#
You can even use it backup your disk partition on another PC ( how to copy compressed drive image over network). It can also be used to implement many complex environment as proxy, sniffer, logger, secure chat, debbugger, fuzzer. It is so simple and so powerful that you can use it either for basic connection tests or in a complex environment, but the most important thing is that is cross-platform, single file and stand-alone program. Great! You have a remote shell of your Mac. Although we can compile a surce code that incluce the option we want, we can also modify the previous exemple to make command execution working. The only preconpiled version I found is an old one, non supporting “executing command” option (-e). This sound like a remote shell using a proxy… Note that pipeling in Machine B has as effect that, in Machine A, you write the command in shell 1 and read output in shell 2. we wait some seconds and … TA-DAAA! In the Machine A we have a remote shell of the Windows system. When all listeners are ready let’s put all together running the 3 clients from Machine B. Let’s start 2 listeners in two different windows in Machine A then one listener with -e option on the Windows PC. We have 3 PCs: machine A and B are Linux, machine C is Windows. Of course you can put together text/command redirection and command execution. The result will be a remore shell of the client on the machine with the listener. You can also set the listener without -e option and use it on the client. In the first window start a service that listens on a specific port using Netcat (this is called listener)Ĭopyright (c) 2009 Microsoft Corporation. The version I found for MacOS don’t have the -e option, but you can recompile it to enable this option or use some workaround as I will explain.įirst try: open two command windows in the same machine.

This is the Windows version of Netcat, but options are similar also in Linux. Port numbers can be individual or ranges: m-n w secs timeout for connects and final net reads L listen harder, re-listen on socket close i secs delay interval for lines sent, ports scanned g gateway source-routing hop point, up to 8
