Please put /cygdrive/c/TeX/HOME/ns2/ns-allinone-2.31/bin:/cygdrive/c/TeX/HOME/ns
2/ns-allinone-2.31/tcl8.4.14/unix:/cygdrive/c/TeX/HOME/ns2/ns-allinone-2.31/tk8.
4.14/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.

IMPORTANT NOTICES:

(1) You MUST put /cygdrive/c/TeX/HOME/ns2/ns-allinone-2.31/otcl-1.13, /cygdrive/
c/TeX/HOME/ns2/ns-allinone-2.31/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 /cygdrive/c/TeX/HOME/ns2/ns-allinone-2.31/tcl8.4.14/library int
o 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-2.31; ./validate
