SMTP, testing via Telnet - FreeBSDwiki
When troubleshooting problems with SMTP service - your own, or others - it is frequently very helpful to be able to "speak" to the SMTP server directly, rather than going through a mail client which won't necessarily tell you exactly what the SMTP server is saying. You can easily do this with the telnet client. Note that many ISPs do not allow outbound connections on port 25 to any SMTP server but their own - if you get timeouts when trying to connect to port 25, you should try port 587, which is the standard ESMTP port. (Port 587 connections normally require SMTP AUTH, which is covered below.)

HOWTO: Successfully using Mutt in an Exchange 2010 Environment
I recently started using Mutt as my full time mail client at the office and have found (through searches and tinkering) a way to use Mutt in conjunction with Wyrd (ncurses front end for Remind) to effectively manage calendar events sent to me via email. In addition, I also found a way to asynchronously create an aliases file from an Active Directory query. The only thing I've found that I can't do with this setup is view shared Exchange calendars. For that I still have to use OWA. I do not do much of it, though, so I'm OK with that for now. These scripts are far from perfect but they work, which was my goal.

Download the scripts from: https://gist.github.com/5527716 or clone them from here: https://gist.github.com/5527716.git

Restore easily - even without storeBackup! The most important aspect of a backup tool is easy restoring from a transparent (native) storage format.
Copies / compresses files to another disk and generates backups with time stamps while saving space by recognizing files with identical contents (even if renamed or copied) and hardlinking them (so each backup is totally complete, independent and autonomous)
Detects identical files in different, independent backups (eg. of different computers)
Splits big image files (from e.g., TrueCrypt, mbox, Xen, KVM, VMware, etc.) or complete devices into small pieces and saves only differences to existing backups, thereby saving space and time
Sophisticated possibilities for including and excluding files and directories.
Support of sparse files.
Supports isolated incremental backups (e.g., when travelling with a laptop) and later integration in master backup.
Supports time shifted replication of backups to additional other disks / locations, even for complex schemes.
Supports checking of backups via md5 sums to eg. recognize bit rot of the hard disk.
Enables checking of (old) files in the source directory with md5 sums in the backup to eg. recognize bit rot of the hard disk.
Fast backups even over slow or high latency network connections.
Contains an entire suite of backup-related tools.

oVirt as a VMware replacement? (self.sysadmin)
It took a long time for us to get oVirt working, and we're currently still just testing it. That said, with EL7, it seems usable. I've generally heard that proxmox is one of the easiest to get going, but we are all Red Hat (well Scientific Linux), and were quite wary of using a "black box" for something as important as VMs.

oVirt is backed by Red Hat, and does seem like it and ProxMox are the most like a VMware environment. The other common tool, OpenStack (which I think has the most momentum behind it), isn't really the same sort of thing IMHO, and very focused on private or public cloud. If you're not looking to enable external (to IT) people to spin up and down VMs on a whim, it's not a great fit.

How familiar with Red Hat Enterprise Linux are you? I'm probably intermediate, and it required our dedicated Linux Admin to get Ovirt working at all. However, now that it's working, the WebGui is pretty point and click, but still non-intuitive. There's going to be a lot of manual reading here to figure out what settings have to be set, what the different options even mean, far less why you'd want them one way or another. It is possible to set up a VM by sort of feeling your way through however.

One other point - all of the tools seem to eventually get down to libvirt and KVM (except maybe Xen), so it wouldn't hurt to get a little familiar with those if you're admining it.
=================================================

I used Ovirt for several years up to version 3.5.

1. It works pretty well. I never had any major problems with it. I did run into a few annoying bugs.

2. You really need to engineer your infrastructure for GlusterFS to make it really shine. It will support shared storage, but most everything I felt was keyed to use Gluster.

3. There are SDKs for it, but when I was using it, the SDKs were not well documented.

4. The Performance was good. I ran about 50 VMs on two servers with another server that acted as a Fibre Channel array.

5. I hated that you had to have an NFS file share to store things like ISO images.

6. Ovirt Node didn't work at all for me. I finally just installed a vanilla Fedora box and then installed Ovirt on there and it worked. Hopefully it's better now.
=================================================

Do you even need to "spec to the max" ? I get maxing servers with RAM but noticed most workloads don't use nearly as much CPU to RAM ratio. I noticed a lot of admins I have worked with with seem to throw hardware at a problem instead of actually looking at the proper sizing. We were able to increase our consolidation ratios by 40% by just using better capacity planning practices. For example, larger clusters, DRS, etc..

Using ed, the Unix line editor
A line editor is a text editor in which each editing command applies to one or more complete lines of text. Line editors predate screen based editors like vi, and originated in an era where a computer operator interacted with a teleprinter (a printer with a keyboard), with no video display, and no ability to move a cursor within a document.

This explains why ed focus on lines instead of screens. This also explains why ed is not so intuitive and not natural to someone coming from the world of screen based editors. To add insult to injury, ed is from a time where memory was very very precious, so using abbreviated commands and very succinct error messages made a lot of sense, but contributed to the overall confusion.

autocutsel
X servers use two schemes to copy text between applications. The first one (old and deprecated) is the cutbuffer. It is a simple buffer in which any application can store text. The other scheme is the selection and works differently. There may be many selections in a single server. An application does not copy data in a selection, it "owns" it. When another application wants to retrieve the content of a selection, it asks the owner.
============

* From
http://mutelight.org/subtleties-of-the-x-clipboard

I'm a Linux person at heart, but for me the two equal and separate selections remain an unfortunate usability problem. Luckily for anyone with the same disposition, Autocutsel can help make X's behavior more logical and intuitive. It's a great little program that synchronizes the cut-buffer with CLIPBOARD, or both the cut-buffer and CLIPBOARD with PRIMARY as well.

Install Autocutsel (pacman -S autocutsel on Arch) and put the following two lines into your .xinitrc (or just run them from a terminal to immediately observe the effects):

autocutsel -fork &
autocutsel -selection PRIMARY -fork &

Now, no matter where you copy and paste from, be it Ctrl+C in Chrome, p in Vim, or through text selection in X, your clipboard is consistent across the entire system.

Pronunciation guide for Unix
Pronunciation guide for UNIX

How do I pronounce vi , or ! , or /* , or ...? You can start a very long and pointless discussion by wondering about this topic on the net. Some people say vye, some say vee-eye (the vi manual suggests this) and some Roman numerologists say six. How you pronounce vi has nothing to do with whether or not you are a true Unix wizard.

Similarly, you'll find that some people pronounce char as care, and that there are lots of ways to say # or /* or ! or tty or /etc. No one pronunciation is correct - enjoy the regional dialects and accents.

What is the exact difference between a 'terminal', a 'shell', a 'tty' and a 'console'?
Lots of good explanations here over the years.
(i added a little bit to the quote to try to make a summary. i might be wrong about all of it.)
-- tmx, 22 aug 2017

Summary:
terminal = tty = text input/output environment; possibly virtual.
tty = teletypewriter - a teleprinter-style device resembling a typewriter.
console = physical terminal (is also used for virtual terminal).
shell = command line interpreter.
command line - the language used to send commands to the command-line interpreter running in a shell from the terminal/terminal emulator. (also used to mean where you type at the "shell prompt".)

Console, terminal and tty are closely related. Originally, they meant a piece of equipment through which you could interact with a computer: ...=

whatswrong - A bash script to do some basic checks on the system
A simple bash script to do some basic checks on the system, and report any problems found. The basic concept is that this script should be run as a first step when debugging any issue. Nothing in the script requires root privileges to run.

Please note that there are some situations where this script may cause a system with problems to hang, for example if there are unavailable mounted volumes.

You can run on any system with internet access directly, even if the disks are remounted read-only:

curl https://raw.github.com/BashtonLtd/whatswrong/master/whatswrong | bash

Alternatively, as long as you have SSH access to the remote system you can download via your local machine, and then send and execute over SSH as follows:

curl https://raw.github.com/BashtonLtd/whatswrong/master/whatswrong | ssh $remote_server bash

My sysadmin toolbox
With Duplicity you can do encrypted backups of your filesystem to a remote server. I use it to backup my home directory to a server in another town. I do incremental backups daily and full backups monthly. My script looks like this:

----------- duplicity_backup.sh -----------
#!/bin/sh
duplicity -i --include /etc --include /boot/loader.conf --include /root --include /usr/local/etc --exclude '**' / scp://username@backupdomain/BACKUP/backup_system
duplicity -i /home/username scp://username@backupdomain/BACKUP/backup_home
-------------------------------------------

The command duplicity --verify scp://username@backupdomain/BACKUP/backup_home /home/username compares the system with the backed up files to check what has changed since the last backup.

To restore a file as it was four days ago you would run:

duplicity -t 4D --file-to-restore personal/project.c scp://username@backupdomain/BACKUP/backup_home /home/username/personal/project.c

====

I also use ssync and FUSE to synchronize my workstation with my notebook (in one direction: notebook -> workstation). I mount the remote directory to /tmp with fusefs-sshfs and then I sync it with my home:

-------------------------------------------
mkdir /tmp 2>/dev/null
mount_fusefs auto /tmp/username sshfs username@workstation: && \
ssync -f /home/username -t /tmp/username 1>>backup_fusefs.log 2>&1
-------------------------------------------

Unison (http://www.cis.upenn.edu/~bcpierce/unison/) is a similar application, with which you can mirror two filesystems bidirectionally.

This is the first in a series of posts describing the system I built to monitor long-running commands.

For me, this started as a way to light a blink 1 LED (https://blink1.thingm.com/) at work when a long build completed, bringing me back to the more important task from whatever may have distracted me. After a recent post by Casey Liss, I’ve added watch notifications to the mix.

Gow (Gnu On Windows) is the lightweight alternative to Cygwin. It uses a convenient Windows installer that installs about 130 extremely useful open source UNIX applications compiled as native win32 binaries. It is designed to be as small as possible, about 10 MB, as opposed to Cygwin which can run well over 100 MB depending upon options.

Colours in Terminal
True Colour (16 million colours) support in various terminal applications and terminals. ---- It's a common confusion about terminal colours... We have this:
Plain ASCII -- ANSI escape codes (16 colour codes with bold/italic and background) -- 256 colour palette (216 colours + 16 ansi + 24 gray) (colors are 24bit) -- 24bit true colour ("888" colours (aka 16 million)).

apphelper - file viewer and saver
apphelper is a general purpose handler for files downloaded from the web or presented as email attachments. I routinely use it with my mail reader (mutt http://freshmeat.net/projects/mutt/) for most attachments and my web browser for things I wish to box view and keep, such as PDFs.

Sam Text Editor by Rob Pike
A minimalist text editor with a graphical user interface, a very powerful command language and remote editing capabilities. Written by Rob Pike (http://genius.cat-v.org/rob-pike/). ---- Also could be considered a graphical version of the venerable ed (http://man.cat-v.org/unix-1st/1/ed) on steroids, lots of steroids.
