Co do portu 135 - musisz sobie przetłumaczyć - aż tak dobroduszny nie jestem...
Port 135 - RPC (Remote Procedure Call, used to admin servers, etc).
Attacks are possible on these ports that can crater a server or
workstation. One that was recently fixed was the TELNET to port 135 on NT
Server and type 10 or more random characters then disconnect. The server's
CPU usage nails to 100% until you reboot it. There's a fix for the Port
135 attack, by not allow these ports from the Internet you can keep outside
attackers at bay with these simple attacks, but you are still vulnerable
from the inside. If you do not use WINS then disable Port 137. If you do
not use remote admin you may be able to disable Port 135, not sure on that
one, never tried. If you do not use any NetBIOS type applications on
TCP/IP then you may be able to disable Ports 138/139. If you have
non-production server then test each one individually, then in groups to
see what happens.
