- 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.

- IOWait. (Sysadmin’s bedtime horror story) – […] hope this helps someone out there. The last 3 days, I have had my server crash on me every 2-3 hours. At first I thought it would be a spike in the traffic, since I couldn’t find any crash reports from Apache, and there was a spike in the traffic at this time. So I increased the resources on the server. It crashed again, every 2-3 hours […] It wasn't my case but… who knows in the future?
- Apache mod_deflate and mod_cache issues | Devon Hillard’s Digital Sanctuary – The Problem: Using Apache mod_deflate and mod_disk_cache (or other mod_cache) together can create far too many cached files. The Background: Apache is a web server with many different modules you can load in to enhance it. Two common ones are mod_deflate and mod_cache (or mod_disk_cache).

- Configuring OpenLDAP pass-through authentication to Active Directory – Alex Tcherniakhovski – Security – Site Home – MSDN Blogs – This particular functionality of OpenLDAP should be of special interest for environments where long term co-existence between OpenLDAP and Active Directory is required. By establishing pass-through authentication the following advantages could be achieved: Great end-user experience. No need to remember multiple passwords Increased security, due to the reduction of the attack surface (one less password store in the environment) Single password policy The rest of the post will expand on the instructions provided by the OpenLDAP 2.4 Administration guide on establishing pass-through authentication from OpenLDAP to Active Directory. Specifically, will will leverage the capability of SASL to use LDAP as an authentication back-end. In our case, Active Directory will play a role of such authentication back-end.
