#Nmap stunnel how to

In the following post, we'll walk you through on how to install Nmap, use it, and, most important, get more to know about your network. The Nmap suite includes an advanced graphical user interface and results viewer ( Zenmap), a flexible data transfer, redirection, and debugging tool ( Ncat), a utility for comparing scan results ( Ndiff), and a packet generation and response analysis tool ( Nping).īesides being free, Nmap is very flexible, portable, well-documented, and easy to use. The tool is used by network administrators to inventory network devices, monitor remote host status, save the scan results for later use, and so on. Nmap is very powerful when it comes to discovering network protocols, scanning open ports, detecting operating systems running on remote machines, etc. Nmap, which stands for 'Network Mapper,' is an open source tool that lets you perform scans on local and remote networks.

The final step is installing the Squid proxy on your Kali Linux Raspberry Pi by issuing the apt-get install squid3 –y command. The next step is to restart the stunnel services by issuing the following command: Sudo nano /usr/local/bin/firewall.sh Iptables –A INPUT –p tcp –dport 993 –j ACCEPT

Then, add a firewall setting on the Raspberry Pi by creating the firewall.sh file using the following commands: Sudo nano /etc/stunnel/nf sslVersion = all options = NO_SSLv2 cert = /etc/stunnel/server.pem pid = /var/run/stunnel.pid output = /var/log/stunnel client = no accept = 993 connect = 34567 Change enable = to enable = Next, open a file called nf and add the following configuration to the file: Once installed, you need to configure stunnel using the sudo nano /etc/default/stunnel4 command. Next, you need to generate your private key using the following commands:Ĭd /etc/stunnel/ openssl genrsa -out key.pem 2048 openssl req -new -x509 -key key.pem -out cert.pem -days 1095 cat key.pem cert.pem > /etc/stunnel/stunnel.pem sudo bash cat server.key > server.pem & cat server.crt > server.pem chmod 400 /etc/stunnel/server.pem The following screenshot shows the configurations in the nf file: Note that you can change the ports to something that better suits you:Ĭlient = no accept = 8888 connect = 127.0.0.1:3128 cert = /etc/stunnel/stunnel.pem The following will be configured and entered into the nf file. You can use your favorite text editor such as nano or vi to create the file. You will need to create a file called nf inside the /etc/stunnel/ directory. You may get a message that the latest version of stunnel is already installed.

#Nmap stunnel code

What makes stunnel cool is it adds SSL functionality to commonly used daemons like POP2, POP3, and IMAP servers without any changes in the program's code. This is done by acting like an SSL encryption wrapper between the remote client and server using industry-standard crypto libraries such as OpenSSL. Stunnel creates secure communication between a TCP client and server by hiding inside another SSL envelope. One method to get around this is levering stunnel. Many administrators will have detection technologies such as IDS/IPS to detect and prevent open VPN connections.
