How do you know if you are communicating via UDP/TCPIP or just using TCPIP.

If my Netware workstations are only running IP and connecting to the ADS
server via

\\128.166.54.22:2004

are we not running straight TCPIP?

I ask because I know in the old days we ran UDP with ADS and need to know if
we are still running it for firewall issues.

Thanks

Hi Don,

The question about how to determine what a given client is using is a good
one, but I'm not sure how to tell without using a network sniffer (e.g.,
Wireshark). The Advantage APIs and system procedures that return connection
information do not differentiate between UDP and TCP/IP (at least that I can
remember).

However, it is most likely still using UDP. By default, the client uses UDP
when attempting to communicate to the server. You can change it to TCP/IP
by adding "use_tcp_ip=1" to the [settings] section of ads.ini.
