activity at all.
  In other words if I disable them will my system stop functioning?

  111    sunrpc

* close this. not needed


  113    auth

* identd authorization port. depending on whether you go on irc
or not, you may want to keep this one open.


  513    login

* You can close this one (not needed for outide stuff)


  514    shell

* close this one too.


  515    lpd

* Unless you want to have people print to your printer from the
outside network I'd close this



  I pretty much get the meaning of what each one is from the name
except
  sunrpc.  Do they need to have an open port for someone to function
on a
  local host though?  Are there any serious ramifications if I
disabled them?
