Configurer un accès SFTP pour préserver son serveur tout en partageant ses données
Sucuri researcher Daniel Cid found that it only took an attacker 12 minutes to compromise an IPv4 server and shortly after, use it to launch a DDoS attack on an unsuspecting victim while performing an experiment to see how long it would take to brute force compromise IPv4-only and IPv6-only servers.
If you run a Secure Shell login service anywhere which is accessible from the Internet, I'm sure you've seen things like these in your authentication logs:
Sep 26 03:12:34 skapet sshd: Failed password for root from
To play NetHack on this server, just telnet to alt.org (on normal port 23 or port 14321) or ssh to email@example.com. Consider putty on Windows.
AsyncSSH is a Python package which provides an asynchronous client and server implementation of the SSHv2 protocol on top of the Python asyncio framework. It requires Python 3.4 or later and the Python cryptography library for some cryptographic functions.
how do I login over ssh without using password less RSA / DSA public keys? How do I use ssh in a shell script? How do I login non-interactivly performing password authentication with SSH and shell scripts?
Now that you are able to create various forward or reverse SSH tunnels with lots of options and even simplify your live with ~/.ssh/config you probably also want to know how make a tunnel persistent. By persistent I mean, that it is made sure the tunnel will always run. For example, once your ssh connection times out (By server-side timeout), your tunnel should be re-established automatically.
Predictable SSH host keys
Le SSH tout le monde le sait, c’est magique. Mais malheureusement ça ne marche pas OOTB.
SSH Tipps & Tricks - RMLL 2015
As Microsoft has shifted towards a more customer-oriented culture, Microsoft engineers are using social networks, tech communities and direct customer feedback as an integral part on how we make decisions about future investments. A popular request the PowerShell team has received is to use Secure Shell protocol and Shell session (aka SSH) to interoperate between Windows and Linux – both Linux connecting to and managing Windows via SSH and, vice versa, Windows connecting to and managing Linux via SSH. Thus, the combination of PowerShell and SSH will deliver a robust and secure solution to automate and to remotely manage Linux and Windows systems.
L'algorithme de signature Ed25519 ayant été mis en œuvre dans OpenSSH, ce nouveau RFC permet d'utiliser cet algorithme dans les enregistrements DNS SSHFP (SSH fingerprint). via @bortzmeyer
