Help with ns-2

I live in southern Maryland. I'm trying to get ns-2 to run on UBUNTU for my dissertation. It's been a while since I've used UNIX or C++ and am struggling with it. I got it to install and verify successfully, but when I type 'ns' it looks like it is pointing to 'host'. When I type man ns, it seems like it gives me the info for host. host is not aliased with ns, and I can't figure out what to do short of re-installing it.

I'm not familiar with ns-2 so I can't help you there, but I recommend that you post this in the help section of the forums. You're much more likely to reach a wider audience and, hopefully, find a solution.

Thanks, I've posted it twice there and got no response. I'm not sure it's related to ns-2, but that the term 'ns' is somehow interpreted as 'host'. I get the same response from the terminal when I type either one. Is there another way that Linux binds user defined terms with system defined commands...like alias, only another way? I used to be very familiar with VMS and DOS both, but not with Linux. There has to be a script file that is executing on login/startup that associates ns with host, but I have no clue where to look.

I'm not sure I understand exactly what you mean, but are you having trouble executing the program? If so, the current working directory is not generally included in PATH by default, so to execute a program or script, you have to include it, as in:

./ns

But this will only work if the program you're trying to execute is in your present working directory. If it's somewhere else, you need to include the path to it.

Your problems with the manual may be the result of "ns" (nameserver) being considered a synonym for "host." That may explain why man brings up entries for host. I'm not on my Ubuntu machine right now so I can't test this. If you're looking for documentation specifically for ns-2, I would suggest trying:

apropos ns-2

Or you can check the website: http://www.isi.edu/nsnam/ns/

I have Ubuntu 7.04 Feisty Fawn OS loaded on my laptop and now I have installed ns2.31 (network simulator) using ns2allinone tar file from sourceforge.com, I have followed all the instructions given in it for installation. But when I try to run ns from the prompt it gives NameServer not responding message. kindly help me.

Pratidnya.

I saw this after a bit of Googling: http://www.dii.unimo.it/wiki/index.php/The_Network_Simulator_-_NS_2

hi community, i have a similar problem with my ns2 on ubuntu 8.04.

I don't know what's the problem, i guess the path is ok, my message:

Usage: host [-v] [-a] [-t querytype] [options] name [server] Listing: host [-v] [-a] [-t querytype] [options] -l zone [server] Hostcount: host [-v] [options] -H [-D] [-E] [-G] zone Check soa: host [-v] [options] -C zone Addrcheck: host [-v] [options] -A host Listing options: [-L level] [-S] [-A] [-p] [-P prefserver] [-N skipzone] Common options: [-d] [-f|-F file] [-I chars] [-i|-n] [-q] [-Q] [-T] [-Z] Other options: [-c class] [-e] [-m] [-o] [-r] [-R] [-s secs] [-u] [-w] Special options: [-O srcaddr] [-j minport] [-J maxport] Extended usage: [-x [name ...]] [-X server [name ...]]

I edit the path (bashrc) with the following lines:

LD_LIBRARY_PATH

or these lines

NS_HOME=/home/relikya/ns-allinone-2.33 export NS_HOME PATH=$PATH:$NS_HOME/bin export PATH

and they show me the same problem

I appreciate your help

I'm also facing the same problem while running ns in Ubuntu......

Hello everybody,

I'm student and i have to make a project to compare two protocols in NS2, MRSVP and M-YESSIR. Does anybody knows were i can find that patces?

Thanks a lot. Constantine

i faced the same problem.. did the following and it got solved

found which ns process was running by typing- which ns it showed /usr/bin/ns removed ns from /usr/ns (rm ns)

then came back to the original directory and successfully ran $ns to get %

NS2 installation problems:

I have run through all the installation steps required for installation of NS2.27 onto my system. But I face following problems

Nam has been installed successfully. ln: creating symbolic link ns': File exists ln: creating symbolic link nam': File exists Please compile your xgraph separately. Please compile your gt-itm & sgb2ns separately. Ns-allinone package has been installed successfully. Here are the installation places: tcl8.4.5: /home/sawyer/ns-allinone-2.27/{bin,include,lib} tk8.4.5: /home/sawyer/ns-allinone-2.27/{bin,include,lib} otcl: /home/sawyer/ns-allinone-2.27/otcl-1.8 tclcl: /home/sawyer/ns-allinone-2.27/tclcl-1.15 ns: /home/sawyer/ns-allinone-2.27/ns-2.27/ns nam: /home/sawyer/ns-allinone-2.27/nam-1.10/nam

but when I give it returns the following

sawyer@sawyer:~$ nam nam: [code omitted because of length] : no event type or button # or keysym while executing "bind Listbox <MouseWheel> { %W yview scroll [expr {- (%D / 120) * 4}] units }"

[B] And when I click on to installation paths above tcl8.4.5,tk8.4.5,ns,nam does not open. [/B]

What may be the problem !!! .

Next is when I go for validation that is after giving the command

sawyer@sawyer:~/ns-allinone-2.27/ns-2.27$ ./validate

Test output agrees with reference output All test output agrees with reference output. *** ./test-all-rng Tests: rngtest Running test rngtest: ../../ns test-suite-rng.tcl rngtest QUIET Test output agrees with reference output All test output agrees with reference output.

Please let me know wat all are the extra packages to be installed. bcoz I am using old version of Ns2 on Ubuntu9.10

Thank you, Sawyer

Hi,

I'm doing a project in ns2. I need some help with the commands. Is there any tutorial or link that gives a detailed understanding of the tcl scripts as we're unable to follow them much. I would also like to know what the following command does.. if {[$class info instprocs config] != ""} { $self config $ns } This is in the test-suite-algorouting.tcl in ns2.

edit the makefile.in and otcl folder file by adding the line in previous suggestion

Hi I need your help, I am using Ubuntu 10.10 that has installed on virtual box on my PC and I need to install NS2 on ubuntu10.10, but once I execute this command:

sudo apt-get install build-essential autoconf automake libxmu-dev

I receive this messages: Reading package lists... Done Building dependency tree Reading state information... Done Package autoconf is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Unable to locate package build-essential E: Package 'autoconf' has no installation candidate E: Unable to locate package automake E: Unable to locate package libxmu-dev w0090766@w0090766-VirtualBox:~/test/ns-allinone-2.34$

What is my mistake, or what I should do to install NS2 on this system?

Could you just install ns2 via the Ubuntu Software Center?
