“strace wget grooveshark.com”以错误的字符串长度停止奇怪的套接字调用,我必须按 Ctrl+C 来终止。
write(2, "Connecting to grooveshark.com (g"..., 67Connecting to grooveshark.com (grooveshark.com)|8.20.213.76|:80... ) = 67
socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3
connect(3, {sa_family=AF_INET, sin_port=htons(80), sin_addr=inet_addr("8.20.213.76")}, 16) = 0
write(2, "connected.\n", 11connected.
) = 11
select(4, NULL, [3], NULL, {900, 0}) = 1 (out [3], left {899, 999993})
write(3, "GET / HTTP/1.1\r\nUser-Agent: Wget"..., 115) = 115
write(2, "HTTP request sent, awaiting resp"..., 40HTTP request sent, awaiting response... ) = 40 [[ Check this line ]]
select(4, [3], NULL, NULL, {900, 0} ^C
write(2, "HTTP request sent, awaiting resp"..., 40HTTP request sent, awaiting response...) = 40
应该
write(2, "HTTP 请求已发送,等待响应...", 40 ) = 40
但是 strace wget google.com 给出了
write(3, "GET / HTTP/1.1\r\nUser-Agent: Wget"..., 116) = 116
write(2, "HTTP request sent, awaiting resp"..., 40) = 40
select(4, [3], NULL, NULL, {900, 0}) = 1 (in [3], left {899, 932611})
并正确终止。
谢谢
