LinuxJournal Cover Story

Linux Journal chose my article about online privacy and security using a password manager as the cover story for this month's edition. You have to be a subscriber to read it right now.

The cover graphic to go with my article could be depicting chop sticks pulling a password out of a data stream, so it's also an article that can be accompanied by Sriracha.

etckeeper at SCaLE 15x

SCaLE accepted my etckeeper talk for SCaLE 15x.

As a system administrator I find it important to track changes in configuration files. Revision control systems have some fatal flaws for tracking /etc/. Luckily Joey Hess' excellent etckeeper wraps several revision control systems and adds the features we need to track our configuration files.

online privacy article for Linux Journal

Linux Journal will be publishing my article about Online Privacy and Security Using a Password Manager in the January edition ( pre-emptive URL ). I adapted my talk ( given at LinuxFest Northwest last year ) for print and concentrated more on the password manager aspect.

Thanks to Linux Journal for accepting my article and publishing it.

Someone Else's Problem night at PLUG

SEP is Someone Else's Problem, so for SEP 2016 PLUG is covering cloud, which is Someone Else's Computers.

We have two talks about dynamically deploying systems. One is an introduction to OpenStack. The other is an overview on deploying dynamic HA environments with HashiCorp's tools.

MySQL for the System Administrator at SeaGL

SeaGL accepted my MySQL for the System Administrator talk. SeaGL is the middle of November in Seattle.

They haven't yet published the talks, so here's my proposal.

There's always a small database somewhere that gets pushed to system administrators without DBA support. Learn some basic skills for maintaining that database. The same skills will help in the middle-ground between sysadmin and DBA.

Verifying debian images signatures and checksums

Verifying signatures

Debian's CD verification page doesn't explain how to find and use the keyring from the package.

This page will explain how to get the keyring package and use it to verify the gpg signatures for the checksum files if you are running debian. The directions will likely work for any debian-based distribution.

Install debian-keyring ( sudo apt install debian-keyring ). Also install gnupg if it isn't already installed ( see GnuPG sidebar for details ).

Monitoring, bluetooth beacons and DEFCON for August PLUG mtg

Chris from Elastic's Kibana team will demo his not yet released project on Alerting and Rhythm ( a server metrics UI ).

Ed will give us an intro to Eddystone Bluetooth Beacons. Perhaps he will talk about the insecurity of most

Phil will give us a short review of his DEFCON trip. Speaking of DEFCON, perhaps Ed will talk about the insecurity of bluetooth smart locks.

scalable log storage and analysis at PLUG

This Thursday Kibana creator Rashid Khan will talk scalable log storage and analysis at PLUG. His talk will cover patterns for log shipping, the problems in traditional centralized log storage, as well as issues with syslog shipping overall. We'll explore the options in the open source space, and define a stack that can be gradually merged into a legacy syslog network, with further optimizations as we later spin down the legacy redundant logging infrastructure.

comparing strings in the shell

While creating materials for my bash class I needed to create some globbing exercises for my students.

It occured to me that a string operator and a comparison to the null string can be used to check if something is a substring of another value.

Sure, you can use Substring Expansion to see if the substring is at a known location such as "Does the value of $foo start with 'bar'?", but length and location are often unknown.

Say, for instance, I wanted to know if it's a word a Dalek would shriek? Easy to do with regular expressions: grep ate$ /usr/share/dict/words.

CentOS Dojo this Friday in Scottsdale

CentOS has started a new series of one day conferences. The second CentOS Dojo is taking place in Scottsdale this Friday. Karanbir Singh is in town to lead the conference.

Scheduled talks cover topics such as Logstash ( scalable log management and searching ), Sensu ( scalable monitoring framework ), CentOS Linux kernel tuning, high volume metrics collection, CentOS and Xen virtualization, ARM architecture servers and SSH.
