Network scanner mac address9/2/2023 ![]() ![]() Finally, if the MAC and IP address tuple was previously unknown ( events passed-new-scan, failed-new-scanor omitted-new-scan), or the scan failed its last two scans ( event failed-scan) for any reason, mac-scan will send e-mail to the e-mail address(es) specified in the Event Notification File (set with the -e switch). Upon receipt of the Nessus scan results, mac-scaninstalls a new entry into the Host Security Scan database. If a MAC and IP address tuple is new (i.e., it has not be previously entered into the database), or the current time is equal to or greater than the MAC and IP address tuple’s next security scan date, mac-scanqueues the host (as a target) for the Nesssus daemon running on the Nessus server to be scanned in bath mode. Next, mac-scan then SQL queries the Host Security Scan database to compare its learned MAC and IP address tuples against all previous recorded MAC and IP address tuples saved in the database. Note, this process is recursive if, e.g., a host’s default router is more than two layer-2 hops away. Regardless which reconnaissance method was used, if a bridged-ports file was specified with the -b switch and the layer-2 device (agent) and port for any learned hosts matches an agent and port tuple bridged-port, the new agent assigned to the bridged-port is then SNMP polled to request updated port information for that host. If SNMPpolling was used for reconnaissance, port information should already have been retrieved for each active host. Hence, if a predominant agents file was specificed with the -p switch and that file contains one or more predominant agents for the ICMP mapped network, then mac-scan will (for each learned host) SNMP poll (using poll-switch) each of the predominant agents in order to ascertain which layer-2 device has knowledge of any learned host, and thus, retrieve the port information for that host. ![]() If ICMP reconnaissance is used to gather active hosts, then mac-scan will not have port information for those hosts. Nmap (set only to use ICMP) can be used to collect all active hosts on a network by using the -N and -p switches. ![]() Mac-scan can use poll-switch (which uses SNMP) to retrieve a list of hosts stored in the specific layer-2 switch’s Dynamic Cam Table for a specific VLAN by using the -V and -r switches. PSC Note due to access lists set on the PostgreSQL database, dirsdb, SNMP access lists on the layer-2/3 switches, and certificate authenication on Nessus servers kgband stasi, mac-scan can (currently) only be run from the user account scanner on sport and warden. Mac-scan uses SNMP via poll-switch, or ICMP via nmap to retrieve a list of active hosts on a VLAN or network, requests scans for the list of hosts via certificate authentication from a Nessus server (set with the -s switch) and upon receipt of those scan results installs the results into a SQL-query-able database ( Security Scan History - see below). Please ensure that this MAC Address is whitelisted in your security infrastructure and Access Control Lists for your secure Wi-Fi network.Mac-scan – Scan hosts on a VLAN or network for vulnerabilities SYNOPSIS MAC Address: The specific ultrasound scanner's MAC Address can be found on the Status page. Thus, the IP Address below in the list, just as it was on the live exam page, is by default dynamically assigned to 192.168.1.1 - this is not the IP Address that will be dynamically assigned on your own secure WiFi network. SSID: Note that in the example we are connected to DIRECT-_ : this is the scanner's own generated Wi-Fi Direct. The MAC Address and dynamically assigned IP address will appear if you are connected to the scanner as described in Step 1.From the top left hand corner, tap the arrow to go back and then access the icon for the main menu (three lines). ![]() You may ignore this IP address.įor more information on the differences, please see Which Wi-Fi Should I Use? Note: If you are connecting via Wi-Fi-Direct, the scanner's own generated Wi-Fi, the IP address shown (encircled in red) is not the IP address that will be dynamically assigned when connecting via your clinic's own secure Wi-Fi network. To ensure you are connected to the scanner, ensure you can see the reactive live exam for your Clarius Ultrasound.
