FILE LIST - echoClient.c DESCRIPTION - The TCP echo client repeatedly sends the input and then reads it back using TCP socket communication. ECHO services are important tools that network managers use to test reachability (to make sure the connection works), debug protocol software, and identify routing problems. This also demonstrates the usage of SO_REUSEADDR, SO_KEEPALIVE and TCP_NODELAY set socket options. RUNNING DEMO - You need to set/change the value of the defaultPort (should be greater than 5000 - unreserved port) and the defaultServer (internet address of the echo server) variables. Run echoTcpClientRun task on one VxWorks system as follows after starting the echoTcpServerRun task from another VxWorks system. The other half of the demonstration is in echoServer.c. Place the echoClient.c file in your <Tornado> dir. Depending on the target you have, define the CPU in your compile line and use the Makefile in the BSP dir. to compile. To run this code invoke the function echoTcpClientRun() TESTED ON - Host/Target : Solaris 2.5.1 /mv1604 VxWorks : 5.3.1 EXAMPLE COMPILE LINE - make CPU=PPC604 echoClient.o %make CPU=PPC604 echoClient.o ccppc -B/petaluma1/mayur/tor101-ppc/host/sun4-solaris2/lib/gcc-lib/ -mstrict-align -ansi -nostdinc -O2 -fvolatile -fno-builtin -fno-for-scope -Wall -I/h -I. -I/petaluma1/mayur/tor101-ppc/target/config/all -I/petaluma1/mayur/tor101-ppc/target/h -I/petaluma1/mayur/tor101-ppc/target/src/config -I/petaluma1/mayur/tor101-ppc/target/src/drv -DCPU=PPC604 -DMV1600 -DTARGET_DIR="\"mv1604\"" -c echoClient.c OUTPUTS/LOGFILE - On VxWorks target: ================== -> ld <echoClient.o value = 917544 = 0xe0028 -> sp (echoTcpClientRun, "147.11.41.154", 7001, 5 , "Hello World!!!") task spawned: id = 5c7c50, name = u14 value = 6061136 = 0x5c7c50 The output on the console window: ================================= Binding SERVER Listening to client Server's address is 930b299a: Connected...
