Linux – How to configure nDPI for iptables

centosiptableslinuxloggingprotocol

I am new to nDPI, I have installed nDPI but when I add rules like;

iptables -I OUTPUT -m ndpi –http -j REJECT
it shows error

iptables v1.4.7: Couldn't load match `ndpi':/lib64/xtables/libipt_ndpi.so: cannot open shared object file: No such file or directory

Try `iptables -h' or 'iptables –help' for more information.

Plz, if anyone can tell me how to configure iptables for nDPI. I am using centOS 6.5

Thanks;

It Seems you have not configured ndpi-netfilter properly. follow all the steps in my blog. https://thingsinlinux.blogspot.com/2016/02/installing-and-configuring-ndpi.html if one step fails, it will not work properly.

Linux Bash – How to Sort du -h Output by Size

As of GNU coreutils 7.5 released in August 2009, sort allows a -h parameter, which allows numeric suffixes of the kind produced by du -h:

du -hs * | sort -h

If you are using a sort that does not support -h, you can install GNU Coreutils. E.g. on an older Mac OS X:

brew install coreutils
du -hs * | gsort -h

From sort manual:

-h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G)

Linux service –status-all shows “Firewall is stopped.” what service does firewall refer to

Edit: After having a chat with the OP we can state the following facts:

It refers to the services iptables and ip6tables.

The errormessage appears when the service ip6tables is on (by chkconfig), but doesn't have any rules.

I advice to set up default IPv6 rules as are given in the stock CentOS 5.8 installation. You may take this as a reference. This was taken from a stock 5.8 installation.

Hope everything is sorted out now :)
