You must be "root" to 'make install' to /usr/local/ :
1) su <password>
2) make install
can you tell me how to get access to a file permanently in fedora 16
If it's in /home/<user-name>/ : You should have access all the time.
Outside /home/<user-name>/ : Use 'su' when you want access.
'ns-allinone-2.32/' is supposed to have location in /home/<user-name>/.
Then you can easily work with all the files.
