It is used by the kernel to handle and report errors in -protocol processing. It may also be accessed by programs using the socket -interface or the Transport Level Interface (\fBTLI\fR) for network monitoring -and diagnostic functions. When used with the socket interface, a "raw socket" -type is used. The protocol number for \fBICMP,\fR used in the \fIproto\fR -parameter to the socket call, can be obtained from -\fBgetprotobyname\fR(3SOCKET). \fBICMP\fR file descriptors and sockets are -connectionless, and are normally used with the \fBt_sndudata\fR / -\fBt_rcvudata\fR and the \fBsendto()\fR / \fBrecvfrom()\fR calls. In order to -send \fBICMP\fR packets, a process needs the \fBPRIV_NET_ICMPACCESS\fR -privilege. (See \fBprivileges\fR(5) for more information on privileges.) -.sp -.LP -Outgoing packets automatically have an Internet Protocol (\fBIP\fR) header -prepended to them. Incoming packets are provided to the user with the \fBIP\fR -header and options intact. -.sp -.LP -\fBICMP\fR is an datagram protocol layered above \fBIP.\fR It is used -internally by the protocol code for various purposes including routing, fault -isolation, and congestion control. Receipt of an \fBICMP\fR "redirect" message -will add a new entry in the routing table, or modify an existing one. -\fBICMP\fR messages are routinely sent by the protocol code. Received -\fBICMP\fR messages may be reflected back to users of higher-level protocols -such as \fBTCP\fR or \fBUDP\fR as error returns from system calls. A copy of -all \fBICMP\fR message received by the system is provided to every holder of an -open \fBICMP\fR socket or \fBTLI\fR descriptor. -.SH SEE ALSO -.LP -\fBgetprotobyname\fR(3SOCKET), \fBrecv\fR(3SOCKET), \fBsend\fR(3SOCKET), -\fBt_rcvudata\fR(3NSL), \fBt_sndudata\fR(3NSL), \fBprivileges\fR(5), -\fBinet\fR(7P), \fBip\fR(7P), \fBrouting\fR(7P) -.sp -.LP -Postel, Jon, \fIInternet Control Message Protocol \(em DARPA Internet Program -Protocol Specification\fR, \fBRFC\fR 792, Network Information Center, \fBSRI\fR -International, Menlo Park, Calif., September 1981. -.SH DIAGNOSTICS -.LP -A socket operation may fail with one of the following errors returned: -.sp -.ne 2 -.na -\fB\fBEISCONN\fR\fR -.ad -.RS 17n -An attempt was made to establish a connection on a socket which already has -one, or when trying to send a datagram with the destination address specified -and the socket is already connected. -.RE - -.sp -.ne 2 -.na -\fB\fBENOTCONN\fR\fR -.ad -.RS 17n -An attempt was made to send a datagram, but no destination address is -specified, and the socket has not been connected. -.RE - -.sp -.ne 2 -.na -\fB\fBENOBUFS\fR\fR -.ad -.RS 17n -The system ran out of memory for an internal data structure. -.RE - -.sp -.ne 2 -.na -\fB\fBEADDRNOTAVAIL\fR\fR -.ad -.RS 17n -An attempt was made to create a socket with a network address for which no -network interface exists. -.RE - -.SH NOTES -.LP -Replies to \fBICMP\fR "echo" messages which are source routed are not sent back -using inverted source routes, but rather go back through the normal routing -mechanisms. |
