Cisco Systems. July 2003. -.SH NOTES -When displaying interface information, \fBnetstat\fR honors the -\fBDEFAULT_IP\fR setting in \fB/etc/default/inet_type\fR. If it is set to -\fBIP_VERSION4\fR, then \fBnetstat\fR will omit information relating to IPv6 -interfaces, statistics, connections, routes and the like. -.LP -However, you can override the \fBDEFAULT_IP\fR setting in -\fB/etc/default/inet_type\fR on the command-line. For example, if you have used -the command-line to explicitly request IPv6 information by using the -\fBinet6\fR address family or one of the IPv6 protocols, it will override the -\fBDEFAULT_IP\fR setting. -.LP -If you need to examine network status information following a kernel crash, use -the \fBmdb\fR(1) utility on the \fBsavecore\fR(1M) output. -.LP -The \fBnetstat\fR utility obtains TCP statistics from the system by opening -\fB/dev/tcp\fR and issuing queries. Because of this, \fBnetstat\fR might -display an extra, unused connection in \fBIDLE\fR state when reporting -connection status. -.LP -Previous versions of \fBnetstat\fR had undocumented methods for reporting -kernel statistics published using the \fBkstat\fR(7D) facility. This -functionality has been removed. Use \fBkstat\fR(1M) instead. -.LP -\fBnetstat\fR restricts its output to information that is relevant to the zone -in which \fBnetstat\fR runs.
