Nc download remote file

Click here for more info. Using Netcat command to download file from remote device. The remote machine and local computer are inside different private networks. Also, the local computer connected behind a NAT router. Originally Posted by dorsio. Originally Posted by unSpawn. Also you didn't include what you have tried?

For example if you can SSH into the machine and you have sufficient rights to perform this you could try 'ssh user remote. I can't download anything with netcat command due to connection timed out. It is most efficient if you tell us exactly what services can or can not be used, what commands you have tried and what errors you get in your initial post. See if busybox provides 'split' command then download each part?

That may or may not work depending on if the remote machine can reach the local machine. You talked about NAT so if you didn't set up port forwarding in your router it is unclear how this could work.

I only see: so you can't reach that host. Not that weird because it's not routable over the Internet. No but if 'dd' accepts "seek" arg you can first 'dd' the device then chunk it write 1m, seek 1m then write 1m, rinse and repeat.

With 'dd "count" is an integer and "bs" is a string as in 1k or 1m: see 'man dd'. Not fully clear here, can you show what should be correct code in my case? No, let's turn that around: you read 'man dd' then you propose what you think your command line should be, then I'll correct if necessary. To copy 3 MB. Find More Posts by Emerson.

Using Netcat You will have one netcat that will send data and the other one for receiving. Sending side nc Compressing You can use linux pipes to compress and decompress Receiving side The receiving side will first xz, the -c flag is writting to the stdout and -d for decompress. Show comments.

You can, because they are separate protocols. There are other methods for transferring files from one system to another. You can also use the netcat command for this purpose. For this example, I created a demo that illustrates a remote file transfer from my Linux machine to my MacBook Pro. You begin listening on the receiving machine on TCP port The name that follows is the local name for the file. The IP address here belongs to the Linux machine.

There might be more efficient options for port scanning, but it can be done with netcat. This attempts to make a connection to ports between This port is normally open on machines because it is used for connecting to the internet.

It successfully connects to port 80, but generates an error message from Apache. I end up with some HTML output on the terminal because my computer sees it as a bad page request. This is the built-in port-scanning mode for netcat. I still get the same language, but it does not actually make the connection to port 80 generating the bad request error. Instead it continues through all scanned ports. This is a more fun way to use netcat. I will show this for demonstration purposes only.

Please be aware that unauthorized use of this command could be considered criminal activity in your locale.

There are ways to do it, but you will have to find them somewhere else. Once again, this is intended only to show the capability. The -e flag makes something executable. A common way for malicious actors to gain access is to create such a backdoor on an open port and use that to execute scripts or otherwise manipulate the file system. Now the attackers can use this backdoor to access into the system remotely and execute commands. This enables the attacker to access your computer remotely from the command line.

Once connected, I can run bash commands similarly to how I could if I was using the computer directly. This makes it very important to monitor port activity on any network. I hope you enjoyed this brief introduction to the netcat command.
