Cross-Post to MVS-OE and IBM-Main Quite a while ago, there was a question (I don't remember on which list) regarding the relation between MAXSOCKETS and INADDRANYPORT, since the IP Comfiguration Guide seems to imply there is one. I had sent an RCF back then and have gotten an answer today. Both my RCF and the answer are attached below. It may be the question originated from the TCPIP list, which Im not subscribed to. If someone wants to forward the post to that list, feel free to do so.

The UNIX System Services developer agrees that there is no relationship between the MAXSOCKETS and the INADDRANYPORT values. We plan to clear up any implications in our documentation. Thanks for alerting us to this situation. Michele Carlo for z/OS Communications Server Customer Information IBM Research Triangle Park, NC -------------------------------------------------------- The RCF I had sent: Hello, There was a discussion about the relation, if any, between MAXSOCKETS and INADDRANYPORT, as impled by the following paragraph: Book: z/OS Communications Server IP Configuration Guide Version 1 Release 7 (SC31-8775-07) Topic: 1.2.14.4 Specifying BPXPRMxx values for a CINET configuration Paragraph: 3 INADDRANYPORT and INADDRANYCOUNT specify the first ephemeral port number and the range of ports for z/OS UNIX CINET usage. *** The starting port number should be set at least as high as the value for MAXSOCKETS. *** ..... The last sentence, marked with *** seems to say there is a relation. I'm not the IP expert but this doesn't sound reasonable to me given the fact that MAXSOCKETS has a valid range from 0 to 16777215 and INADDRANYPORT must be in the range from 1024 to 65534. Also, I understand MAXSOCKETS to define the size of "socket table" for a given address family. INADDRANYPORT/COUNT tell the CINET layer what range of ports has been defined to be the ephemeral port space. This must match the PORTRANGE in the TCP/IP profile(s). I don't see how MAXSOCKETS and INADDRANYPORT are related. May I kindly ask you to verify the paragraph in question?
