NET.CFG Options Reference
Protocol TCPIP Option
User Datagram Protocol (UDP) Sockets
User Datagram Protocol (UDP) sockets are used by the LWPCON utility and by all applications that query a name server using the domain name system (DNS). DNS name servers are the only type of name server that the TCP/IP Transport for DOS software supports.
The software accesses a DNS name server through the information provided in the RESOLV.CFG file. See Chapter 2, “Setting Up Domain Name Systems (DNS) Support,” in the TCP/IP Transport for DOS Configuration Guide for more information.
Because UDP sockets are used briefly to send and receive datagrams and are then released, you need more than the default eight UDP sockets only if you make very heavy use of DNS.
UDP_SOCKETS number
Specifies the maximum number concurrent UDP sockets (connections).
If you are using DNS, set at least one UDP socket for each concurrently run application.
If you are using NetBIOS, set at least two UDP sockets.
If you are configuring multiple ODI LAN drivers for TCP/IP, set the number of UDP sockets to the total shared by all LAN drivers.
