Package: libpcap0.8-dev
Version: 0.9.8-5
Severity: important
With the following program, about 50% of the time the pcap_next fails
with "Error reading from eth0".
If you comment out the pcap_setdirection line you never get this, data is
always read.
#include <pcap.h>
main()
{
pcap_t *pcap;
const u_char *buffer;
struct pcap_pkthdr header;
char errbuf[PCAP_ERRBUF_SIZE];
pcap = pcap_open_live("eth0", BUFSIZ, 1, 1000, errbuf);
if(pcap == NULL) {
fprintf(stderr, "eth0: %s\n", errbuf);
return 1;
}
pcap_setdirection(pcap, PCAP_D_IN);
buffer = pcap_next(pcap, &header);
if(buffer == NULL) {
fputs("Error reading from eth0\n", stderr);
pcap_close(pcap);
return 2;
}
pcap_close(pcap);
printf("Read %d bytes\n", header.len);
return 0;
}
