     • Eth0           = Connected to Internet  
     • Eth1           = Connected to LAN

Please remember without the Squid and DNS setup, no use of installing sarg on the system it will won’t work at all. Before installing Sarg we must configure DNS and Squid as Transparent Proxy. DNS for the name resolution in caching mode.

If you have not created a S3 bucket kindly go through with EC2 documentation.The documentation is very clear and easy to understand .

S3FS is FUSE (File System in User Space) based solution to mount an Amazon S3 buckets. On s3fs mounted files systems we can simply use cp, mv and ls the basic Unix commands similar to run on locally attached disks.

   root@ip-172-31-24-7:~# make
   root@ip-172-31-24-7:~# make install

Step 4 - Now we can install s3fs dependency packages on this server
apt-get install build-essential gcc libfuse-dev fuse-utils libcurl4-openssl-dev libxml2-dev mime-support build-essential libcurl4-openssl-dev

Step 5 - Download and Compile Latest S3FS using below example and extract.
URL : wget

Step 6 - Open /etc/fuse.conf file to make small change. Uncomment the line #user_allow_other.
