I have a variety of PCs in my house running Linux CentOS, Windows 7 and Mac OSX 10.8 Mountain Lion. Something was bothering me: I could not “see” my Linux laptop with my MacBook Pro like I “see” all the other PC/devices in my LAN.

I did some research and I found a great site that explain step by step how to install the Nettalk protocol on CentoOS so to solve the issue:


The explanations are very straight forward. I tested it personally and I found it very easy to follow. And it works. I have one of minor caveat for you to pay attention to:

  1. When updating the IP TABLE config file on "/etc/sysconfig/iptables" copy and paste the following:
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 548 -j ACCEPT
    If you copy/paste the line directly from the blog you wind up with a syntax error because of the double dash requirement "- -"

When installed and turned on you should be able to “see” your Linux PC from your Mac. If you don’t just go to “Finder->Go->Connect To Server”, type the IP and you’re connected.
