Functions ¶
func HasIPConnected ¶
func HasListeningPort ¶
func HasLocalIP ¶
HasLocalIP compares an input ip address with the ip addresses of the local interfaces, and returns found=true when found
func HasLocalMAC ¶
HasLocalMac returns the mac addresses that match an input MAC regex
func HasSeenIP ¶
HasSeenIP on linux looks for a matching IP address in /proc/net/arp or in individual processes <pid>/net/arp, and returns its MAC and IP address if found
func HasSeenMac ¶
HasSeenMac on linux looks for a matching mac address in /proc/net/arp or in individual processes <pid>/net/arp, and returns its MAC and IP address if found
Types ¶
type NetstatWinOutput ¶
type NetstatWinOutput struct {
Entries []netstatWinEntry
}
NetstatWinOutput supports functions for parsing and responding to queries based on the output of the windows netstat -na command.
func (*NetstatWinOutput) HasIPConnected ¶
func (n *NetstatWinOutput) HasIPConnected(ipnet *net.IPNet) []element
HasIPConnected searches the parsed Entries for matches based on ipnet. This function also increments stats.Examined for each entry that is processed.
func (*NetstatWinOutput) HasListeningPort ¶
func (n *NetstatWinOutput) HasListeningPort(port int) []element
HasListeningPort returns elements with matching host listeners for the given port.
func (*NetstatWinOutput) UnmarshalText ¶
func (n *NetstatWinOutput) UnmarshalText(text []byte) error
UnmarshalText parses the output of windows netstat -na containing IPv4 and IPv6 addresses into the NetstatWinOutput struct.
Sample windows netstat -na output: Active Connections Proto Local Address Foreign Address State TCP 0.0.0.0:135 0.0.0.0:0 LISTENING TCP 0.0.0.0:445 0.0.0.0:0 LISTENING UDP [fe80::1c5a:2c75:6ce3:9f0%3]:1900 *:* UDP [fe80::1c5a:2c75:6ce3:9f0%3]:54109 *:*
