Re: [ns] Drop packet!!!!!
Hi Mohammed, That's correct. Only the object whose class derives from class Connector can call the function drop(p). However, there are a lot of class like this, e.g., queues, agents.

[ns] increase queue delay
Hi all, Is there a way (or a module or a website I can look at it) to increase the delay of queue at a node by a specific value? If I increase the delay of the queue, will packets timestamps reflect that (meaning packets will arrive later)? Thank you

Re: [ns] Debugging ns code (.cc files) with print statements
printf works! I had two copies of ns and I made changes to one of them. The PATH variable was pointing to the original ns folder. Whereas, I wanted to test the result of the changes made in the ns-copy folder. When I gave, ns file1.tcl, the original ns pointed out by PATH was being used. Hence, I could not see the effect of the changes although I was able to compile them successfully. To see which ns folder is being used, issue the command "which ns". To use the ns other than the default one pointed by PATH, traverse to the new ns folder and to the location in which the tcl file is located and give "../../ns file1.tcl" Thanks to my teachers who helped me by pointing out my mistake. --- On Thu, 17/3/11, Ns Learner wrote: From: Ns Learner Subject: Re: [ns] Debugging ns code (.cc files) with print statements To: "pedro chaparro" , ns-users@ISI.EDU Received: Thursday, 17 March, 2011, 2:27 PM Thanks, Pedro. I used printf in tcp.cc file inside the methods that are usually called. But, I don't get any statements printed on the console. What could be the mistake? Thanks. --- On Thu, 17/3/11, pedro chaparro wrote: From: pedro chaparro Subject: Re: [ns] Debugging ns code (.cc files) with print statements To: "Ns Learner" Received: Thursday, 17 March, 2011, 4:42 AM u can use printf, bu cout should works too!!! 2011/3/14 Ns Learner Hello, I am trying to debug ns code (.cc files) with print or cout statements.
