一般情况下,已经完善的模块会考虑很多种情形,远超我们日常使用的场景,所以我们需要提纲挈领,最小启动即可! >>>fromnetaddrimportIPAddress>>>ip1=IPAddress('192.168.2.1')>>>ip2=IPAddress('2001::1')>>>ip3=IPAddress('2001::1-aaa')Traceback(mostrecentcalllast):File"<stdin>",line1,in<module>Fil...
If no addresses are specified on the command line, they will be read from stdin The options are: @<file> Read options from <file> -a --addresses Show addresses -b --target=<bfdname> Set the binary file format -e --exe=<executable> Set the input file name (default is a.out) ...
recvfrom要求第5个参数是指向sockaddr结构的指针,第6个参数是指向socklen_t的指针。 man recvfrom (3)说: 如果地址的实际长度大于所提供的sockaddr结构的长度,则存储的地址将被截断。 我不明白如何检索带有AF_INET6地址家族的发送套接字的地址,因为sockaddr_in6的大小大于sockaddr,因此它将被recvfrom截断。 re...

Use -f file_name or -F file_name to read the node names from a file. Use -f "-" or -F "-" to specify STDIN as the input file. Notes: Specify one node name per line. The command ignores any blank characters to the left of the node name. Use a number sign (#) to indicat...
