In an earlier article, I talked about how I recently set up a Ubiquiti access point (model UAP-AC-PRO-US). There are a variety of commands you can run directly on the access point by logging in via SSH. In order to do this, you may need to modify the login credentials. This article will show you [ ]
I recently set up a Ubiquiti access point (model UAP-AC-PRO-US). Part of the process required me to log into the access point, but I could not find any connection details such as the port, username, or password. After a bit of digging, I figured it out. Logging into AP before it is adopted When your [ ]
When you remove a package (such as sudo apt remove php5.5-cgi), all files added by the package will be deleted except for user configuration files that were modified. When you purge a package (such as sudo apt purge php5.5-cgi), all the package files, including modified configuration files, are deleted. After a few years, your Ubuntu [ ]
Did you just receive some mail notifications saying that mail could not be delivered to some.address.it.wont.ever.reach@lookup.and.try.to.find.this.host.name? Fear not. This isn t some kind of weird hack or compromise of your system. In all likelihood, someone just compiled PHP on the server. PHP s unit test to confirm that bug 72463 remains fixed makes two mail() calls that [ ]
I recently did some work on an Ubuntu server with a compromised PHP site that was sending out massive amounts of spam email messages. After removing the offending scripts, I needed to clear out the mail queue to ensure that the server was not attempting to send backlogged spam messages. The server in question is [ ]
I rely on Bitbucket s API heavily to manage repositories at iThemes. Recently, some of the API calls started to fail and returned nonsensical error messages. When making a PUT request to the /1.0/repositories/TEAM/SLUG endpoint, I received an error response with a status code of 400 and the following message: ul class="errorlist" li project ul class="errorlist" li Select a valid choice.

Ubuntu s time and date indicator in Unity is a bit blah for my tastes. With the default settings on my system, it currently says 7:39 AM . That s accurate, but it could be much more helpful. You can load up the Time Date application from the dash, click the Clock tab, and customize the appearance a [ ]
I ve been tinkering around with LXC containers on my Ubuntu systems. While setting up my user for unprivileged usage, I ran into the following problem: [chris@server ~]$ lxc-attach -n u1 lxc_container: cgmanager.c: cgm_attach: 1291 Failed to get cgroup for controller all lxc_container: attach.c: lxc_attach: 847 error communicating with child process [chris@server ~]$ After a bit [ ]
For the past few weeks I ve had problems logging into servers using my SSH keys from Ubuntu desktops. The following would happen each time: [chris@work ~]$ ssh server Agent admitted failure to sign using the key. Permission denied (publickey). [chris@work ~]$ Oddly, this only happened from my Ubuntu desktop systems. My Ubuntu servers had no [ ]
I recently set up an IPv6 interface on a remote Ubuntu server. In order to finish this change, I needed to restart the interface. A while back, I would have used sudo service networking restart, but that doesn t work very well any more: [chris@server ~]$ sudo service networking restart stop: Job failed while stopping start: [ ]
