Octo Network Scanner

1

Target

Specify a target IP address for scanning.

Examples:

10.0.0.0
10.0.0.0/24
10.0.0.0-10.0.0.5
10.0.0.0,10.0.0.1-10.0.0.5,10.0.1.0/24
2

Resolve DNS

Tells Octo Network Scanner to always do reverse DNS resolution on the target IP addresses.

3

No Port Scan

Tells Octo Network Scanner not to do a port scan after host discovery. (optional)

4

Top Thousand Ports

Scans the thousand highest-ratio ports found. (optional)

5

TCP SYN Scan

A fast technique that sends SYN packets to detect open ports without completing the full TCP handshake. (optional)

6

Ports to Scan

Specifies the ports to be scanned. (optional)

Examples:

443
443-1000
443,900-1000

Notes:

  • No Port Scan, Top Thousand Ports, and Ports to Scan cannot be used simultaneously.

  • No Port Scan and TCP SYN Scan cannot be used simultaneously.

7

ICMP Ping

Sends an echo request to a host and waits for an echo reply to check if it is alive. (optional)

8

ARP Scan

Sends ARP requests on a local network to discover active hosts. (optional)

9

No Ping Scan

Skips the host discovery stage altogether. (optional)

10

TCP SYN Ping

Sends an empty TCP packet with the SYN flag set. (optional)

11

TCP ACK Ping

Similar to the SYN ping, but sets the TCP ACK flag instead of SYN. (optional)

12

UDP Ping

Sends UDP packets to the specified ports. (optional)

13

SCTP INIT Ping

Sends an SCTP packet containing a minimal INIT chunk. (optional)

14

Aggressive Scan

Enables additional advanced/aggressive options. Presently this enables OS detection, version scanning, script scan and traceroute. (optional)

15

Service Discovery

Enables service and version detection. (optional)

Notes:

  • Aggressive Scan and Service Discovery cannot be used simultaneously.

  • No Ping Scan, TCP SYN Ping, TCP ACK Ping, UDP Ping and SCTP INIT Ping cannot be used simultaneously.

16

Min Parallelism

Controls the total number of probes that may be outstanding for a host group. (optional, default: 5, rules: min: 1, max: 32)

17

Min Rate

Octo Network Scan's dynamic timing does a good job of finding an appropriate speed at which to scan. (optional, default: 10000)
