Wireshark 未打开 pcap_dump 文件
我试图以 libpcap 格式保存该文件的输出，尽管该文件确实已保存并且正确的数据已写入其中，但 Wireshark 无法打开它。有人看到我在这里缺少什么吗？谢谢。
// opening the device here to listen
handle = pcap_open_live( dev, BUFSIZ, 1, 1000, errbuf );
unsigned int dlt = DLT_EN10MB;
pcap_set_datalink(handle,dlt );
FILE *filename;
filename = fopen("/workarea/capture","a+");
pcap_dumper_t * dump = NULL;
// opens the file
dump = pcap_dump_open( handle, (const char *)filename );
pcap_loop(handle,-1,my_callback,(unsigned char *)filename);
return (0);
}
void my_callback(u_char *dump,const struct pcap_pkthdr* pkthdr,const u_char *packet)
{
unsigned int i=0;
pcap_dump(dump,pkthdr,packet);
}
I am trying to save the output of this file in libpcap format and although the file does get saved and the right data is written into it, Wireshark is unable to open it. Anyone see what I am missing here ? Thanks.

您对
pcap_dump_open的调用似乎不正确。它正在传递 FILE* 指针，但应该传递文件名。使用 pcap_dump_fopen 作为 FILE 指针。或者继续使用 pcap_dump_open 但只需将文件名传递给它。Your call to
pcap_dump_opendoes not seem correct. It is passing a FILE* pointer but should be passing a file name. Usepcap_dump_fopenfor a FILE pointer. Or continue using pcap_dump_open but simply pass the file name to it.
