title: IO exception: Size Data Unit (SDU) mismatch. Vendor code 17002
body: <p>I am connecting through VPN to school site to access DB.
  I use SQL developer 3.0.04 to connect this database. But if I try to connect it this exception is thrown: "IO exception: Size Data Unit (SDU) mismatch. Vendor code 17002"</p>
  
  <p>Does anybody have experience with that kind of problem? I really cannot find solution.
  Thanks a lot!</p>
