Hi,
[quote]Q1: If we have an empty uxsrsrv.alias or if it doesnt exist, would $U on that node operate on ports 10600-10615 as default?[/quote]
If uxsrsrv.alias is empty or does not exist, $U will use /etc/services file to find its ports.
[quote]Q2: If some nodes are using diff set of ports, would the file uxsrsrv.alias consist of service ports of these specific nodes ONLY? In another words, it WOULDN'T have to define the 10600-10615 as well, right?[/quote]
Yes, in the uxsrsrv.alias file, you only have to define the nodes that communicate on specific ports. You do not need to redefine all nodes.
