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.

JS NICE: Statistical renaming, Type inference and Deobfuscation – Welcome to JSNice — we make even obfuscated JavaScript code readable. We will rename variables and parameters to names that we learn from thousands of open source projects. Furthermore, often we are also able to guess or infer type annotations. Try JSNice on your JavaScript code to see how it works! Override the names suggested by JSNice (by enabling "interactive renames" in settings).

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[32347]: 0123456789: host smtp-in.orange.fr[193.252.22.65] refused to talk to me: 421 mwinf5c34 ME Trop de connexions, veuillez verifier votre configuration. Too many connections, slow down. OFR004_104 [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.
Aral Balkan: Historical Archiveâ€Š—â€ŠHow to revert (roll back) to a previous revision with Subversion – Here, then, is a very simple, plain English explanation of how to revert to a previous version of your application in Subversion, to help anyone who may be starting out with it and is lost.
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.

PeteNetLive – KB0000741 – HP and Cisco – VLANs and Trunks Confusion! – When I first started in IT, I went and did my Cisco CCNA. So I learned that to connect Cisco switches and pass VLAN traffic between them, I needed to create a 'Trunk' to pass the VLAN traffic. Fast forward a few years, and I now work for an HP reseller. Very early on I came to realise that what HP called a 'trunk' was very different from what I had been taught. Below is an article I did a while ago about setting up HP Trunks.
OpenNOP – Open Network Optimization Platform – OpenNOP is an open source Linux based network accelerator. It's designed to optimise network traffic over point-to-point, partially-meshed and full-meshed IP networks.
The goal of OpenNOP is to increase network performance over low speed network connections such as ISDN, DSL, DS1, frame-relay, VPN and other network circuits. To accomplish this we can use a variety of techniques such as compression, deduplication, caching and protocol spoofing.
The objectives for OpenNOP are:
Produce a low cost solution to increase network performance, improve the end user experience and deliver this in a easy to use appliance image.
Provide a single solution for networks on terrestrial, cellular and satellite systems.
Facilitate an open framework that can be extended by 3rd party modules to improve specific network traffic.
Deon’s World – Understanding and using htop to monitor system resources – Every so often there will be something that slows a system down.

Microsoft have a wonderfully long history of badly designed software that they're proudly continuing to this day with the abomination of IE 9 and the ghastly sham that is Windows 7. It's a tribute to the skills of the many hard-working marketing heads over at Redmond that despite the poor quality and the easy availability of superior cost-free alternatives, people the world over keep coming back to Microsoft like hookers on crack.

PsPasswd – Systems administrators that manage local administrative accounts on multiple computers regularly need to change the account password as part of standard security practices. PsPasswd is a tool that lets you change an account password on the local or remote systems, enabling administrators to create batch files that run PsPasswd against the computers they manage in order to perform a mass change of the administrator password.
PsPasswd uses Windows password reset APIs, so does not send passwords over the network in the clear.

Forgot the Administrator’s Password? – Change Domain Admin Password in Windows Server 2003 AD – Note: In order to successfully use this trick you must first use one of the password resetting tools available on the Forgot the Administrator's Password? page.
Forgot the Windows Administrator’s Password? – Windows Password Recovery – Windows Password Reset – Ok, so you say you forgot your Windows administrator's password, huh? Oh well, it doesn't really matter if you did or you just say you did. The fact is that you need to gain access to a computer and you cannot "remember" the administrator's password. How can you get out of this situation without formatting and re-installing the operating system?
How to reset the Domain Admin Password under Windows 2003 Server – Seb’s Corner – I have recently installed a Windows 2003 Server at home and I set up a local domain using Active Directory features. Everything worked fine until I changed the Domain Admin password. It seems that I mistyped the new password twice (which I would attribute to the previous heavy night out), and, well, I could not log on the Domain Controller anymore (I did not have a backup admin account, I do now!).

Server World – Build Network Server – This site explains how to build home server connected to internet with static IP address. You need to get at least one static IP address from your ISP. Please make sure the terms of use from your ISP, and Get one or some IP addresses if possibles. It's possible to build a network server, not with static IP address but with dynamic IP address by using Dynamic DNS, though. But I don't recommend it because there are some limits. It's the best to get at least one static IP address in order to build a network server, there is no limit. To get one static IP address is not so high costs. It's easy to build network server at your home.
This site explains how to configure a server with commands basically, not with Graphical User Interfaces.
