Hi, I am new to libpcap, and I am trying to use the following to get the list of network devices available to libpcap by calling pcap_findalldevs().
Manpage mentions, "there may be network devices that cannot be opened by the process calling pcap_findalldevs(3), because, for example, that process does not have sufficient privileges to open them for capturing; if so, those devices will not appear on the list". What does "sufficient privileges" mean? If I run the process as sudoer, it sounds like there shouldn't be any privilege issue. What else will prevent pcap_findalldevs() from returning a network device on the list? Thanks in advance. _______________________________________________ tcpdump-workers mailing list tcpdump-workers@lists.tcpdump.org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
