Functions | |
pcap_t * | pcap_opensource_remote (const char *source, struct pcap_rmtauth *auth, char *errbuf) |
It opens a remote adapter by opening an RPCAP connection and so on. | |
int | pcap_startcapture_remote (pcap_t *fp) |
It starts a remote capture. | |
int | pcap_read_nocb_remote (pcap_t *p, struct pcap_pkthdr **pkt_header, u_char **pkt_data) |
It reads a packet from the network socket. This does not make use of callback (hence the "nocb" string into its name). | |
int | pcap_read_remote (pcap_t *p, int cnt, pcap_handler callback, u_char *user) |
It reads a packet from the network socket. | |
int | pcap_updatefilter_remote (pcap_t *fp, struct bpf_program *prog) |
Update a filter on a remote host. | |
int | pcap_setfilter_remote (pcap_t *fp, struct bpf_program *prog) |
Send a filter to a remote host. | |
int | pcap_stats_remote (pcap_t *p, struct pcap_stat *ps) |
It retrieves network statistics from the other peer. | |
int | pcap_setsampling_remote (pcap_t *p) |
Set sampling parameters in the remote host. | |
pcap_stat * | pcap_stats_ex_remote (pcap_t *p) |
It retrieves network statistics from the other peer. | |
void | pcap_close_remote (pcap_t *p) |
It sends a CLOSE command to the capture server. | |
void | rpcap_createhdr (struct rpcap_header *header, uint8 type, uint16 value, uint32 length) |
Creates a structure of type rpcap_header. | |
int | rpcap_deseraddr (struct sockaddr_storage *sockaddrin, struct sockaddr_storage **sockaddrout, char *errbuf) |
It traslates (i.e. de-serializes) a 'sockaddr_storage' structure from the network byte order to the host byte order. | |
int | rpcap_checkmsg (char *errbuf, SOCKET sock, struct rpcap_header *header, uint8 first,...) |
Checks if the header of the received message is correct. | |
int | rpcap_senderror (SOCKET sock, char *error, unsigned short errcode, char *errbuf) |
It sends a RPCAP error to the other peer. | |
int | rpcap_sendauth (SOCKET sock, struct pcap_rmtauth *auth, char *errbuf) |
Sends the authentication message. | |
int | rpcap_remoteact_getsock (const char *host, char *errbuf) |
It returns the socket currently used for this active connection (active mode only). |
This file declares some typedefs that MUST be of a specific size. These definitions (i.e. typedefs) could need to be changed on other platforms than Intel IA32.
This file defines some structures that are used to transfer data on the network. Be careful that you compiler MUST not insert padding into these structures for better alignment. These structures have been created in order to be correctly aligned to a 32 bits boundary, but be careful in any case.
