Package: ike-scan (1.7-4)

discover and fingerprint IKE hosts (IPsec VPN Servers)

ike-scan discovers IKE hosts and can also fingerprint them using the retransmission backoff pattern.

ike-scan does two things:

a) Discovery: Determine which hosts are running IKE.

   This is done by displaying those hosts which respond to the IKE requests
   sent by ike-scan.
   .

   This is done by recording the times of the IKE response packets from the
   target hosts and comparing the observed retransmission backoff pattern
   against known patterns.
   .
   The retransmission backoff fingerprinting concept is discussed in more
   detail in the UDP backoff fingerprinting paper which should be included
   in the ike-scan kit as udp-backoff-fingerprinting-paper.txt.
