Functions

func HostPort

func HostPort(s, defaultPort string) (string, error)

HostPort will check if the host part is a valid IP address, if the IP address is valid, but no port is found, defaultPort is added.

func HostPortOrFile(s ...string) ([]string, error)

HostPortOrFile parses the strings in s, each string can either be a address, [scheme://]address:port or a filename. The address part is checked and in case of filename a resolv.conf like file is (assumed) and parsed and the nameservers found are returned.

TransferIn parses transfer statements: 'transfer from [address...]'.
