[ns] Changing TCL file and script while running
Dear all, I run (Ubuntu 2.6.27-7-server) a script with several simulation scenarios. Here are the first lines of my script which uses another script and the several simulations are very similar: ** #!/bin/bash sim_name=35p3tcps1a ns IGoXFAN.tcl 1.1429 3 1 0.25 ./exe.sh 3 10.0 rm cpt_elastic_all.tr rm temps*.txt cp cpt_elastic_backup.tr cpt_elastic_all.tr rm cpt_elastic_backup.tr mkdir $sim_name cp *.txt $sim_name cp *.tr $sim_name sim_name=70p3tcps1a ns IGoXFAN.tcl 0.5714 3 1 0.25 ./exe.sh 3 10.0 rm cpt_elastic_all.tr rm temps*.txt cp cpt_elastic_backup.tr cpt_elastic_all.tr rm cpt_elastic_backup.tr mkdir $sim_name cp *.txt $sim_name cp *.tr $sim_name etc ** I just discover my TCL file and my script has a non trascendent error for the previous results but for future simulations. I do not have time to re-run my simulations from the beginning but I want to correct the future ones. Two questions. a) Can I change the value of some parameters (not the event generation) in my TCL so the new values are taken into account? b) Can I change the script (showed above) and the new simulations will take into account such changes? I would appreciate any comment on that, please accept my best regards, César
[ns] Installing ns-2.28, 2.29 under Gentoo or Ubuntu
Dear all, I need to install ns-2.28 or ns.2.29 under Gentoo 2.6.30 r8 or under Ubuntu 2.6.27-7-server because I want to install WFQ for DiffServ: http://sergioandreozzi.com/research/network/diffserv4ns/ http://www.augustoneto.com/technical.html http://www.mail-archive.com/ns-users@isi.edu/msg01073.html I already have ns-2.30, 2.31 and 2.34 on both machines. When I try to install either ns-2.28 and ns-2.29 I got several errors, some of them related to: ./common/packet.h:173: warning: deprecated conversion from string constant to âchar*â ./sctp/sctp.h:253: warning: âtypedefâ was ignored in this declaration But finally they don't compile: make: *** [trace/trace.o] Error 1 Ns make failed! I tried to look at the following webpage http://www.isi.edu/nsnam/ns/ns-problems.html for problems But the patch does not work. http://www/isi.edu/nsnam/dist/solaris.patch Any points to solve this problem will be very appreciated. All the best, César Cárdenas
[ns] Help on STDERR
Dear all, I made a script to run several simulations (same file with different input parameters).
