To remove world permissions from compiler executables

Perform this procedure to clear the “other” user permissions on specific GCC-compiler files on an NSP component station.

Note: It is recommended that you perform the procedure only during a scheduled maintenance period.

Note: You require root user privileges on the station.


1	Log in to the NSP component station as the root user.
2	Open a console window.
3	Paste the following command block into the console window: `chmod 750 /usr/bin/c89` `chmod 750 /usr/bin/c99` `chmod 750 /usr/bin/cc` `chmod 750 /usr/bin/f95` `chmod 750 /usr/bin/gcc` `chmod 750 /usr/bin/gcc-ar` `chmod 750 /usr/bin/gcc-nm` `chmod 750 /usr/bin/gcc-ranlib` `chmod 750 /usr/bin/gcov` `chmod 750 /usr/bin/x86_64-redhat-linux-gcc` `chmod 750 /usr/bin/c++` `chmod 750 /usr/bin/g++` `chmod 750 /usr/bin/x86_64-redhat-linux-c++` `chmod 750 /usr/bin/x86_64-redhat-linux-g++` `chmod 750 /usr/bin/gfortran` The file permissions are reset.
4	Close the console window. End of steps
