Note: I was not having any issues connecting to the general internet with WiFi or Ethernet... both were problem free until I started troubleshooting this issue by attempting SSH connections in Safe Mode and Recovery Mode...since then, and restarting, I have to turn off Wifi and turn it back on before I am allowed to connect. That said, I have a brand new MBPro running 10.8.4 with all of the updates installed. I am constantly having issues connecting to servers that are required for me to perform my job... and it feels related. For Windows servers, SMB connections constantly fail. I will attempt to connect via the Finder GUI -> Go -> Connect to Server... and if I'm lucky, I can usually maintain a slow connection for about 15 minutes max before it freezes and I receive a message informing me that I have been disconnected. For Linux servers, I am usually using the built-in terminal and using various types of connections...usually SSH but also SFTP. Here, I am lucky to be on the other server for 5 minutes before it freezes and I get a Write failed: broken pipe message in the Terminal (not even trying to write anything to the server... I've tested it where I don't do anything on the server and I still get the message). I have researched this to exhaustion...tried various solutions...but to no avail. It seems like there is a setting *somewhere* that is timing me out, but I have no idea where it is. This sucks because I know previous iterations of Mac OS X have worked perfectly with these tools... what is going on now? The point of me getting a Mac was for the dual use of a windows and UNIX interfaces. Hopefully someone has some ideas... thanks!
