Re: [ns] after recompiling
Hi, You can add these two statements at the beginning of proxytrace2any.cc: extern int IsLittleEndian(void); extern void ToOtherEndian(TEntry *e); It'll works well. However, I don't know the reason. If you know, please let me know.

[ns] LAN Nodes placement
Hi Everybody,
I am running the following code bu every time I run, nodes appear in different
positions and overall visualization is very bad. How can I fix the positions of
which node to appear where (while it is still part of LAN!). Also, I send data
between two nodes, which goes to the main bus and is distributed to all nodes.
How can I restrict the communication between two specific nodes only.
Please reply soon.

Re: [ns] problem during NS-2.27 installation
Hi... I already had problems with NS-2.27 intallation too, but a friend helped me, doing the installation. In this case, I was using Ubuntu 8.04 and the most of problems that appeared was because my version of gcc... Now, I'm using another computer, with Ubuntu 8.10, and have to install the NS-2.27 again. In these next days I'm going to install with his help (my friend)... If you don't have solved your problem yet, maybe I can help you! Good luck! -- === Dalton Cézane - Voip UFCG: 1075-2005 Mestrando em Ciência da Computação Bacharel em Ciência da Computação Universidade Federal de Campina Grande - UFCG
