GOAL:
Do Raw Mode sockets impact Progress
FACT(s) (Environment):
Windows XP SP2
FIX:
No, it has no impact on Progress.
Progress does not use raw mode sockets in the 4GL socket interface nor in any of the various other network interfaces such as between 4gl client and database server.
"raw mode sockets" are sockets such that one can construct packets in their entirety and transmit them over the link. That means you can do many things, like construct IP packets with headers that have an incorrect (someone else's) source IP address.
When the destination IP address receives a packet, they will think it was sent by someone else and may reply to the wrong address. This is the basis for a variety of denial of service attacks.
There are a variety of legitimate uses for raw mode sockets, but they should
not be (allowed to be) used in most applications.
