Naming Schemes – A good naming scheme is scalable, unique, and easy to remember. The purpose of these naming schemes is to name networked servers, wireless access points or client computers, but it can also be used to name projects, products, variables, streets, pets, kids, or any other project where unique names and rememberable names are required.
SSD Cloud Hosting & VPS – MNX.io – Here at MNX, we’ve been busy setting up a brand new data center for our cloud hosted services. We started off as a consulting company providing managed Linux services, which means we have been exposed to a ton of different customer environments and an equal number of schemes for naming equipment…not all of them good. It’s a problem that goes back as far as computers have existed, and everyone has their own opinion on the “best” way to name hosts. Most methods start out fine at the beginning, but quickly become unwieldy as infrastructure expands and adapts over time.

Bash: parsing arguments with ‘getopts’ | rsalveti’s random thoughts – Today I was writing some scripts, and in every script I wanted something to handle all input arguments, in a good way, so I could pass my arguments in any order and my program would know about it. I used ‘getopts’ before, but this time I decided to write some stuff here about it.
dayid’s screen and tmux cheat sheet – A comparison of the features (or more-so just a table of notes for accessing some of those features) for GNU screen and BSD-licensed tmux.

Ralentir le débit de postfix pour wanadoo/orange – Le blog de Michauko – Si vous avez un serveur d’envoi de mails (je ne parle pas d’être un spammeur) et beaucoup d’abonnés chez Wanadoo et Orange, vous risquez fort le rejet temporaire de votre serveur si le débit d’envoi est trop fort. C’est ce qui m’est arrivé et hop, 5000 mails entassés dans la file de postfix.
smtp-in.orange.fr refused to talk to me: postfix solution | floriancrouzat.net – Orange sadly limits inbound connexion to it’s MX to 1 connexion per IP, which is a total pain in the ass when you try to deliver newsletter, or manage a MTA. Here is a sample log from their MX: Jul 4 10:42:42 smtp.example.com postfix/smtp: 0123456789: host smtp-in.orange.fr[220.127.116.11] refused to talk to me: 421 mwinf5c34 ME Trop de connexions, veuillez verifier votre configuration. Too many connections, slow down. OFR004_104  However, since they won’t change anything, we have to take mesures, here’s what you can do if you run postfix: you have to set a per-destination concurrency limit.
Tmux: A Simple Start – In all likelihood, you’ve probably already heard of tmux. However, you may not be using it everyday. If tmux is on your “Someday” list because you think it is too complicated (I mean, c’mon, the word “multiplexer” is just plain scary), then I am here to show you just how easy it is to put tmux into your workflow.
Tyblog | Yet Another Vim Setup – Vim is an excellent text editor. I’ve used it for many years and like most vim users, have collected a fairly large collection of settings in my .vimrc and learned how to grok my vim usage effectively through a lot of trial and error. To that end, I’ve tried to assemble a useful overview of my experience with vim.

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.
NetApp – Index – The following documentation is a guide on using and configuring the NetApp servers, there is also a commandline cheat sheet. I have tried to make this section as brief as possible but still cover a broad range of information regarding the NetApp product but I point you to the Official NetApp web site which contains all the documentation you will ever need.
