You know your wife is a keeper when she gets you a YubiKey 4 for your birthday! I was really excited about this YubiKey because of its support for storing your GPG private keys and also for an SSH private key, in addition to the U2F (Universal 2nd Factor) support. I’ve …

Last week’s TechMail was Two-factor SSH authentication via Google secures Linux logins which talks about using Google two-factor authentication with SSH (and PAM in general). I really like it and it works quite well although the comments in the TechMail indicate another …

This week’s mac tip is Two SSH clients to consider for the iPad. In this tip I look at two really great SSH clients for the iPad (and iPhone as well, although I was mostly just looking at the iPad versions which do vary from their iPhone counterpart): iSSH and Prompt. …

Last week’s techmail was Tips and tricks to help you do more with OpenSSH which is a followup to the previous tip that talked about OpenSSH key management. This one gives you a few one-liner tips to stimulate the imagination (yet are useful on their own) with the kinds of …

This week’s techmail is What you need to know about OpenSSH key management which looks at a few tips and tricks in using OpenSSH public/private keys. It talks about generating keys, using ssh-copy-id to copy keys to servers, and using hashed representations of host keys to …

This week’s TechMail is Secure remote firewall administration via SSH which talks about using ssh to create a secure tunnel to a remote network/system to use with configuring a remote firewall. I use this quite a bit with remotely-deployed pfSense boxen to configure it …

This week was interesting, dealing with the supposed “OpenSSH 0day” vulnerability stuff… rumours, innuendo, strange logs and packet capture files… it made for a long week trying to keep an eye on this and sort fact from fiction. Instead of focusing on …

This week’s TechMail is Remotely monitor servers with the Nagios check_by_ssh plugin which discusses using the check_by_ssh plugin in Nagios to get local plugin results from remote systems, via ssh. I use this to monitor my VPS and other remote systems so I can see things …

This week’s TechMail is Save time managing multiple systems with Parallel SSH, which discusses using pssh (or Parallel SSH) to do similar operations on multiple systems at the exact same time. Very useful little program indeed.

Haven’t been keeping up with the TechMails, so here’s the last three works worth. This one is entitled Use Fuse to mount remote ssh directories and it discusses how to use Fuse (user-space filesystem) to mount remote ssh directories as “local” filesystems. …

Last week’s TechMail was Chroot users with OpenSSH: An easier way to confine users to their home directories which discusses the new chroot capabilities of newer openssh. Chrooted sftp is very very cool and a welcome addition to openssh, although it would be neat if …

The last TechMail is Realize the flexibility of OpenSSH which talks about some of the basics of using OpenSSH, from setting up keys to modifying sshd_config for user/group access controls and different features per group/user. OpenSSH is another of my favourite tools. Of course, …

In light of the recent Debian debacle and to get the word out to more people, this week’s Techmail is Find and fix weak OpenSSL/OpenSSH keys: Debian-based Linux vulnerability which more or less reiterates what happened with the Debian OpenSSL… fun… and points …

Another Techrepublic tip is up, entitled Specify who can log in via OpenSSH. I love writing about OpenSSH… it’s probably, weirdly enough, one of my favourite programs. I can’t imagine not having it or even surviving one day (of work) without it. This tip talks …
