Earlier I was working on a clients Mac OSX laptop and needed to login remotely without the hassle of setting a password and then removing it when I was done. The article below will describe not only how to enable SSH from a terminal window on the Macintosh laptop itself but also how to configure SSH so it will allow remote login via SSH without a password.

While messing around with a client’s laptop this afternoon I needed to enable SSH and decided to not only do it via the CLI but locate the method to do it via the Mac OSX Desktop as well. Enabling SSH via the OSX GUI can be done via the Sharing sub section of System Preferences by checking one box. Below is information on how to launch OSX System Preferences, navigate to enabling services in Sharing, and then enabling SSH.

A friend asked me to help him clean up his iTunes library on his iMac the other night so I asked him to bring it by. When he did I realized what had happened which is he had moved the location of his iTunes folder from his computer to an external drive. After moving the folder he imported all of his music again which caused iTunes to think his 8,000 MP3′s had become 16,000 MP3′s. Half of the tracks had red exclamation points by them because iTunes had information about them but could no longer locate the file since he had moved all of the music to a new folder in a different location. I found an easy solution to resolve this problem on a Mac which I describe in detail below.

A friend of mine called the other day and asked if I would stop by to help him setup and configure an external hard drive he had purchased and unsuccessfully setup on his Mac desktop. Upon initial inspection I figured I would just uninstall the WD SmartWare software, reformat the drive, and set it up to simply act as a secondary drive. It turns out that the initial releases of the SmartWare software would require you to configure the drive using SmartWare so I instead of completely wiping the SmartWare software I decided to simply minimize the impact the SmartWare software would have on what my friend wanted to do which was simply have a secondary hard drive that he could copy files to. Below are a couple steps I took to minimize what the WD SmartWare software would do or require you to do before copying files to the external Western Digital hard drive. The first couple of steps are to make sure that the configuration we are starting with is from scratch and sense my friend started the install I wasn’t sure what had been configured so it was better to start over.

Use the below syntax from the Terminal window on a Macintosh computer running OS X 10.5 (Leopard) to clear the DNS cache for the computer.

dscacheutil -flushcache

You might need to flush the DNS cache if you know a DNS change has been made recently but your Mac is not showing the change. OS X does a good job of DNS caching but it may take longer than you want to wait to update a changed DNS setting and running the above command will solve your issue without having to reboot.
