We blogged about ipt_pkd in our previous posts here.
So, “ipt_pkd is an iptables extension implementing port knock detection. This project provides 3 parts: the kernel module ipt_pkd, the iptables user space module libipt_pkd.so, and a user space client knock program. For the knock packet, it uses a UDP packet sent to a random port that contains a SHA-256 of a time-stamp, small header, random bytes, and a shared key. ipt_pkd checks the time window of the packet and does the SHA-256 to verify the packet. The shared key is never sent.”
Now, ipt_pkd has been updated to version 1.6!
These are the changes made:
This version was updated for Linux 2.6.32 and iptables 1.4.6.
A new knock client was added, written in C# and works on both Linux and Windows and encrypts configuration data.
A pre-built kernel module, an iptables library for vyatta community edition 5, and a small install script for vyatta were added.
Download ipt_pkd version 1.6 here.

“OpenSSH is a FREE version of the SSH connectivity tools that technical users of the Internet rely on. Users of telnet, rlogin, and ftp may not realize that their password is transmitted across the Internet unencrypted, but it is. OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks. Additionally, OpenSSH provides secure tunneling capabilities and several authentication methods, and supports all SSH protocol versions.”
