install ns2


NS2是研究所時候玩的一個Network Simulator,今天忽然心血來潮的回味一下,下載網址

我下載了ns-allinone-2.35-RC4,解開後執行裡面的install即可。安裝過程中,我只有遇到can't find X includes
checking for X11 header files
can't find X includes
otcl-1.14 configuration failed! Exiting ...
Please check http://www.isi.edu/nsnam/ns/ns-problems.html
for common problems and bug fixes.
透過安裝libsx-dev即可解決
sudo apt-get install libsx-dev


安裝成功後應該會出現一些重要的訊息,包含將執行目錄加到您的PATH中:
Please put ns-allinone-2.35/bin:ns-allinone-2.35/tcl8.5.8/unix:ns-allinone-2.35/tk8.5.8/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.

IMPORTANT NOTICES:

(1) You MUST put ns-allinone-2.35/otcl-1.14, ns-allinone-2.35/lib, 
    into your LD_LIBRARY_PATH environment variable.
    If it complains about X libraries, add path to your X libraries 
    into LD_LIBRARY_PATH.
    If you are using csh, you can set it like:
                setenv LD_LIBRARY_PATH <paths>
    If you are using sh, you can set it like:
                export LD_LIBRARY_PATH=<paths>

(2) You MUST put ns-allinone-2.35/tcl8.5.8/library into your TCL_LIBRARY environmental
    variable. Otherwise ns/nam will complain during startup.

After these steps, you can now run the ns validation suite with
cd ns-2.35; ./validate

For trouble shooting, please first read ns problems page 
http://www.isi.edu/nsnam/ns/ns-problems.html. Also search the ns mailing list archive
for related posts.

接下來就是執行一下ns2內建的一些tcl檔:
brook@ubuntu:~/src/ns2$ PATH=/home/brook/src/ns2/ns-allinone-2.35/bin:/home/brook/src/ns2/ns-allinone-2.35/tcl8.5.8/unix:/home/brook/src/ns2/ns-allinone-2.35/tk8.5.8/unix:$PATH
brook@ubuntu:~/src/ns2$ ns ns-allinone-2.35/ns-2.35/tcl/ex/simple.tcl
