OpenSSH – Wikibooks, open books for an open world – The OpenSSH suite provides secure remote access and file transfer. Since its initial release, it has grown to become the most widely used implementation of the SSH protocol. During the first ten years of its existence, ssh has largely replaced older corresponding unencrypted tools and protocols. The OpenSSH client is included by default in most operating system distributions, including OS X, Linux, BSD and Solaris. Any day you use the Internet, you are using and relying on dozens if not hundreds of machines operated and maintained using OpenSSH. A survey in 2008 showed that of the SSH servers found running, just over 80% were OpenSSH.  OpenSSH was first released towards the end of 1999. It is the latest step in a very long and useful history of networked computing, remote access and telecommuting. This book is for fellow users of OpenSSH to help them save effort and time through using OpenSSH, and especially SFTP, where it makes sense to use it.
ssl-cert-check » Linux Shtuff – [...] Digital certificates have become an essential part of Internet commerce, and are widely used to verify the identity of clients and servers. All digital certificates contain an expiration date which most client and server applications will check before using the certificates contents. If a client or server application detects that a certificate has expired, one or more implementation specific actions (e.g., abort connection, check or update a revocation list, alert user, etc.) are typically performed.[...]

SSH Multi-hop Connections With Netcat Mode Proxy | Click & Find Answer ! – Since OpenSSH 5.4 there is a new feature called natcat mode, which allows you to bind STDIN and STDOUT of local SSH client to a TCP port accessible through the remote SSH server. This mode is enabled by simply calling ssh -W [HOST]:[PORT] Theoretically this should be ideal for use in the ProxyCommand setting in per-host SSH configurations, which was previously often used with the nc (netcat) command. ProxyCommand allows you to configure a machine as proxy between you local machine and the target SSH server, for example if the target SSH server is hidden behind a firewall. The problem now is, that instead of working, it throws a cryptic error message in my face: Bad packet length 1397966893.Disconnecting: Packet corrupt
Tyblog | SSH Kung Fu – OpenSSH is an incredible tool. Though primarily relied upon as a secure alternative to plaintext remote tools like telnet or rsh, OpenSSH (hereafter referred to as plain old ssh) has become a swiss army knife of functionality for far more than just remote logins. I rely on ssh every day for multiple purposes and feel the need to share the love for this excellent tool. What follows is a list for some of my use cases that leverage the power of ssh.

Opencall – Open Source Call Tracking Software – Call tracking is a method of monitoring inbound phone calls. It allows you to record conversations, track key statistics such as caller id, call duration, call source and streamline your sales, customer service and marketing. Opencall is the world’s first (and only) open source call tracking software. The software is available under the GPL v3 license, is written in PHP and utilises MySQL as the database platform. The original Opencall source code was written and developed by CallTracking Hong Kong to service clients in Hong Kong and other Asian countries. After 8 months of internal development the founder of CallTracking, Scott Bowler, decided to release their proprietary code to the public and change his business model to servicing companies who would make use of the open source call tracking platform. The major driver behind this choice was to open up the product to a global user base and encourage more rapid development of the platform.
