Member Function Documentation

getHostName()

result< std::string > e2sar::NetUtil::getHostName ( )

staticnoexcept

Get the hostname of the host

getInterfaceIPs()

result< std::vector< ip::address > > e2sar::NetUtil::getInterfaceIPs ( const std::string & interfaceName, bool v6 = false )

staticnoexcept

get IPs of an interface (by name), either IPv4 or IPv6

getMTU()

size_t e2sar::NetUtil::getMTU ( const std::string & interfaceName )

staticnoexcept

Get MTU of a given interface

Parameters

interfaceName

- name of the interface

Returns

MTU or 1500 as the best guess

Get MTU of a given interface. Used in constructors, so doesn't return error.

isNonRoutable() [1/2]

bool e2sar::NetUtil::isNonRoutable ( const std::string & addr_str )

staticnoexcept

Check if an IP address string is non-routable (private RFC1918, loopback, link-local, IPv6 ULA, or unspecified). Returns false on parse failure.

isNonRoutable() [2/2]

bool e2sar::NetUtil::isNonRoutable ( const std::vector< std::string > & addrs )

staticnoexcept

Check if any address in the vector is non-routable.
