  • 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. [1] 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.

  • Observium – Observium is an autodiscovering SNMP based network monitoring platform written in PHP which includes support for a wide range of network hardware and operating systems including Cisco, Windows, Linux, HP, Dell, FreeBSD, Juniper, Brocade, Netscaler, NetApp and many more. Observium has grown out of a lack of network monitoring platforms which are both simple to manage and pleasant to use. It is intended to provide a navigable interface to the health and performance of your network. Its design goals include collecting as much historical data about devices as possible, using as much auto-discovery as possible with little or no manual intervention, and having a very intuitive interface. Observium is not intended to replace an up/down alerting system like Icinga or Nagios, but rather to complement it with an easy to manage, intuitive representation of historical and current performance statistics, configuration visualisation and syslog capture.
  • nikratio / S3QL — Bitbucket – S3QL is a file system that stores all its data online using storage services like Google Storage, Amazon S3, or OpenStack. S3QL effectively provides a hard disk of dynamic, infinite capacity that can be accessed from any computer with internet access running Linux, FreeBSD or OS-X. S3QL is a standard conforming, full featured UNIX file system that is conceptually indistinguishable from any local file system. Furthermore, S3QL has additional features like compression, encryption, data de-duplication, immutable trees and snapshotting which make it especially suitable for online backup and archival. S3QL is designed to favor simplicity and elegance over performance and feature-creep. Care has been taken to make the source code as readable and serviceable as possible. Solid error detection and error handling have been included from the very first line, and S3QL comes with extensive automated test cases for all its components.
  • Secure encrypted backup using duplicity for Linux and Mac – I have been looking for a replacement alternative to Dropbox which I use on my Mac mainly for backups (I rarely use the sharing). The requirements were secure encrypted backup (where I control the keys) and “intelligence” so incremental backups could be performed i.e. not copying everything every time[…]
  • Duplicati – Duplicati is a free backup client that securely stores encrypted, incremental, compressed backups on cloud storage services and remote file servers. It works with Amazon S3, Windows Live SkyDrive, Google Drive (Google Docs), Rackspace Cloud Files or WebDAV, SSH, FTP (and many more).   Duplicati has built-in AES-256 encryption and backups can be signed using GNU Privacy Guard. A built-in scheduler makes sure that backups are always up-to-date. Last but not least, Duplicati provides various options and tweaks like filters, deletion rules, transfer and bandwidth options to run backups for specific purposes. Duplicati is licensed under LGPL and available for Windows and Linux (.NET 2.0+ or Mono required). The Duplicati project was inspired by duplicity. Duplicati and duplicity are similar but not compatible. Duplicati is available in English, Spanish, French, German, Danish, Portugese, Italian, and Chinese.

  • Ratuus – RATUUS is an easy to use, web based system for administration of POSTFIX virtual domains and users. Sounds good, but what does it really mean? Postfix mail server is able to work with non-system users, users which are not known to the operating system. This functionality is very useful since it gives you possibility to use one mail server for multiple domains without worrying that usernames will overlap. Like this you can have address [email protected] and also [email protected] and they can all point to different mailboxes. These kind of users are usually stored in some kind of a database, with MySQL database being most commonly used. And this is where RATUUS comes into play – it provides user friendly interface for managing these virtual users and domains. With RATUUS you can easily create, modify and delete domains, users and aliases and all your actions are immediately reflected to Postfix configuration. RATUUS is using the same database layout as famous PostfixAdmin so migration

  • Beleth – Security101 – Blackhat Techniques – Hacking Tutorials – Vulnerability Research – Security Tools – Beleth is a multi-threaded asynchronous SSH password auditing tool written in C.

After preliminary tests, Beleth was able to outperform both THC-Hydra and Ncrack. Beleth also allows you to run a remote command after successfully cracking a password.

  • Epoptes – Epoptes (ΕπÏŒπτης  – a Greek word for overseer) is an open source computer lab management and monitoring tool. It allows for screen broadcasting and monitoring, remote command execution, message sending, imposing restrictions like screen locking or sound muting the clients and much more! It can be installed in Ubuntu, Debian and openSUSE based labs that may contain any combination of the following: LTSP servers, thin and fat clients, non LTSP servers, standalone workstations, NX or XDMCP clients etc. Patches for other distros are welcome.
  • bcache – Bcache is a Linux kernel block layer cache. It allows one or more fast disk drives such as flash-based solid state drives (SSDs) to act as a cache for one or more slower hard disk drives. Hard drives are cheap and big, SSDs are fast but small and expensive. Wouldn't it be nice if you could transparently get the advantages of both? With Bcache, you can have your cake and eat it too. Bcache patches for the Linux kernel allow one to use SSDs to cache other block devices. It's analogous to L2Arc for ZFS, but Bcache also does writeback caching (besides just write through caching), and it's filesystem agnostic. It's designed to be switched on with a minimum of effort, and to work well without configuration on any setup. By default it won't cache sequential IO, just the random reads and writes that SSDs excel at. It's meant to be suitable for desktops, servers, high end storage arrays, and perhaps even embedded.
