- Deis | Your Paas. Your Rules. – Deis (pronounced DAY-iss) is an open source PaaS that makes it easy to deploy and manage applications on your own servers. Deis builds upon Docker and CoreOS to provide a lightweight PaaS with a Heroku-inspired workflow.
- Speed up WordPress on DreamHost with OPcache
Installing OPcache can improve your site’s performance by decreasing the php execution process when a script is requested. DreamHost permits a user to log into the server through secure shell with user level permissions. Since user level permissions cannot install software, the module will need to be manually compiled.
- Reduce TIME_WAIT socket connections | Linux BrigadeReduce TIME_WAIT socket connections in Apache/Linux
Some time in your life you’ll run across an Apache server that always has tons of TIME_WAIT connections just seeming to hang out. While these don’t take up as many resources as an ESTABLISHED connection, why keep them around so long? This short article will show you how to identify how many you have, and how to tell your server to reduce them, reuse and recycle them (see, recycling IS a good thing).
- Analyzing Apache Log Files < System | The Art of Web
There are many different packages that allow you to generate reports on who’s visiting your site and what they’re doing. The most popular at this time appear to be “Analog”, “The Webalizer” and “AWStats” which are installed by default on many shared servers. While such programs generate attractive reports, they only scratch the surface of what the log files can tell you. In this section we look at ways you can delve more deeply – focussing on the use of simple command line tools, particularly grep, awk and sed.
These are my links for 16 Mar 2016 through 24 Mar 2016:
- “Reverse Engineering for Beginners” free book –
- Resolve Hardware Status Alert SEL_FULLNESS | Brian Ragazzi – […] I noticed an alert on two UCS B250M2 hosts in the vSphere Client. The alert Name was “Status of other host hardware objects”. This isn’t helpful. To get more information, you have to navigate to the Hardware Status tab of the host properties. Here I saw more information about the alert. It’s cryptically named “System Board 0 SEL_FULLNESS”. […]
- Network Stack: Cisco ASA Packet Capture – […] The ASA platform has fantastic built-in packet capture capabilities which can come in very handy for troubleshooting issues. I will be demonstrating some of the capabilities using an ASA 5505 running version 9.0(1).Performing a packet capture is done using the capture command from privileged exec mode. […][ Fantastic… I won’t say that ]
- Multistage environments with Ansible – Ross Tuck – Ansible has excellent documentation but one thing I was confused about was the best way to store the configuration for multistage projects: say, different passwords for dev, staging, production. This isn’t really covered in the ansible-examples repo because it’s specific to your project and while the documentation has recommendations, it doesn’t spell it out completely (which I need since I’m an idiot).
These are my links for 19 set 2013 through 25 set 2013:
- AIXchange: Restricting FTP Access (AIX) – A customer was trying to restrict user access to a particular directory on an AIX system when FTP was used. We came across two good options.
- FBI Tor Malware Analysis – […] In April 2013, a piece of malware was found embedded in Freedom Hosting's darknet server that would exploit a security hole in a particular web browser and execute code on the user's computer. This code gathered some information about the user and sent it to a server in Virginia and then crashed – it had no obvious malicious intent that is so characteristic of malware. It was therefore theorised that the FBI, who have offices in Virginia, and who have 'form' for writing malware, may have authored it – this now appears to be true. […]
- Samba4 and OpenChange on a Debian or Ubuntu server – Samba4/Openchange suite promises to provide a complete Active Directory© domain controller with an alternative to a Microsoft Exchange server. Gracefully to the rewrite of MAPI protocol, Outlook can now seamlessly connect to a Linux server for synchronizing and sharing calendars, contacts, tasks and mails.
