commit 9108a20c409161bc5a0ed06e2d34918334846acf

    Tighten up DNS check in arvdock.
    
    I got arvdock stuck in an infinite loop because I had the right
    nameserver line in /etc/resolv.conf, except it was commented out, so
    arvdock kept checking for a name that it would never find.  Use awk to
    find and check the first functional nameserver line instead.
    
    No issue #.
