Unformatted text preview: T2,8= CLOSEWAIT, 9 = LASTACK, 10 = CLOSING, 11 = TIMEWAIT, 12 = delete TCB. The only value that the manager can set this variable to is 12 (e.g., immediately terminate the connection). Local IP address. 0.0.0.0 indicates the listener is willing to accept connections on any interface. tcpConnLocalPort [0..65535] Local port number. tcpConnRemAddress IpAddress Remote IP address. tcpConnRemPort [0..65535] Remote port number. Figure 25.28 TCP connection table: tcpConnTable. Let's look at this table on the system sun. We show only a portion of the table, since there are many servers listening for connections. Before dumping this table two TCP connections were established: sun % rlogin gemini and sun % telnet localhost IP address o/gemini is 140.252.1.11 IP address should be 127.0.0.1 The only listening server that we show is the FTP server, on port 21: sun % snmpi -a sun dump tcpConnTable tcpConnState.0.0.0.0.21.0.0.0.0.0=listen(2) tcpConnState.127.0.0.1.23.127.0.0.1.1415=established(5) tcpConnState.127.0.0.1.1415.127.0.0.1.23=established(5) tcpConnState.140.252.1.29.1023.140.252.1.11.513=established(5) file:///D|/Documents%20and%20Settings/bigini/Doc...omenet2run/tcpip/tcp-ip-illustrated/snmp_sim.htm (25 of 33) [12/09/2001 14.47.40] Chapter 25.
