    sudden loss of ability to access network (can ssh in but not ssh out)

    I have a machine running Red Hat enterprise Linux. When I came in this morning it was unable to access the network in any way. Ping and ssh both time out, I can't access websites. However, I had an open ssh session up from a couple days ago where I was logged remotely onto a different computer and that did not break off and was still working normally. Also, I can still ssh into the Red Hat machine from a different machine (running OsX in this case). So somehow it seems able to accept connections going in but not going out.

    I don't think I changed any settings or anything that should have affected internet connection between yesterday and today when this problem happened.

    Does anyone have any ideas what could be causing this or how to fix it?!
