Send/Receive a File with Netcat

Posted on February 25, 2023 by admin

For clarity of instructions, we will use the following terminology.

Server = Remote system, typically like a web server
Client = Local system, the computer/vm you are using

Download file from Server

Server

Run the following command on the server.

cat file.txt | nc -l -p 1234

Client

Now on the client we can download the file with the following. Change the IP to the Server IP address

nc 192.168.1.20 1234 > file.txt

Upload from Client to Server

If we want to reverse this, aka. send a file from the client to the server, we can do the following

Server

This will write the file to file.txt

nc -l -p1234 -q 1 > file.txt < /dev/null

Client

Send file.txt to 192.168.1.20. Change the file and IP address as needed.

cat file.txt | nc 192.168.1.20 1234

How To tell if an email on a cPanel server has been read from the command line

Posted on September 24, 2020 by admin

All of the emails in the email directories contain one of the following at the end of the filename

$ ls cur/ | cut -d: -f 2 | sort | uniq -c
54 2,               <- Not Read
12 2,ab             <- Not Read
83 2,S              <- Read
61 2,Sab            <- Read

The first two “2, and 2,ab” mean that the message has not been read. The bottom 2 “2,S and s,Sab” mean that the message has been read or “seen?”. Guess that is what the S is for. Not sure what ab is for.
