> @ faza2004 > invalid command name "ARQTx" Looks like you are using the wrong executable 'ns'. If you are sure that the "arq-Tx" files were compiled into a new 'ns', then make a copy of this new ns, to a new name : 1) $ cp ns ns229-arq 2) $ sudo cp ns229-arq /usr/local/bin/
Suggest : Rename arq.tcl to a new name. We already have tcl/ex/hdlc/arq.tcl in the later ns-2.xx versions. My example : $ ns229-arq arq-Tx.tcl At 100, The tcp sequence number is 60110 .... I.e. the simulation example replies with one line only. (And some warnings.)
