msrv's Introduction

msrv

description

Msrv is a bash script which allows to easily start simple server types to quickly deliver files via a range of protocols, or spawn a reverse shell listener via netcat.

The following server types are available:

nc (for reverse shell listener)
http (for http file transfer)
ftp (for ftp file transfer)
tftp (for tftp file transfer)
smb (for smb file transfer)
ssh (for ssh login and file transfer)
smtp (for faking a simple smtp server)

Msrv displays your tun0-IP and useful status information, as well as the used commands, so you can easily include them in reports or scripts.
