Sandbox library with statically linked system calls to avoid restricted function. INSTALLATION

Note, there is no need to install 32bit packages on x86_64 systems. The 64bit libsandbox and pysandbox can handle both 32bit and 64bit binary programs.

source packages

for c/c++

$ cd libsandbox/Sandbox/libsandbox

$ ./configure

$ sudo make install

$ sudo vim /etc/ld.so.conf.d/sandbox.conf

/usr/local/lib

/usr/local/lib64

$ sudo ldconfig

for python

$ cd libsandbox/Sandbox/pysandbox

$ python setup.py build

$ sudo python setup.py install

GETTING STARTED

The simplest way to get started with the sandbox libraries is to invoke the Python

$ python sample2.py "exe name"

for ex : $ python sample2.py testing

To invoke sandbox by c program $ ./sandbox testing

output : hello result: OK cpu: 2ms mem: 4292kB

if u  get above output means sandbox is working fine ;

(optional) Compilation steps for cSandbox.c

gcc -o sandbox cSandbox.c -lsandbox

Set execute permissions :

sudo chmod u+x sandbox

sudo chmod u+x sample2.py

if setup sandboxing in php environment and still facing problem then set ownership to www-data/apache for /var/www/html directory .

Command with changing ownership :

for ubuntu :

sudo chown www-data -R /var/www/html

for others :

sudo chown apache -R /var/www/html

Still facing any issue ,try this command.

sudo chmod -R 777 /var/www/html
