It is recommended that you install the McIDAS-X 2022 ADDE remote server. End-user access to datasets defined by the user mcidas is most easily done through the ADDE remote server. If you do not install the ADDE remote server, each user will need to define ADDE datasets using DSSERVE in the same way that mcidas does.
If you choose to not install the ADDE remote server, proceed to Removing the Previous Version of McIDAS-X.
The 2022 ADDE remote server uses port 112 for gzip-compressed and uncompressed data transfers. See Clients and Servers, and Appendix I, McIDAS-X Site Administration and Management for more information about remote servers.
Continue with the procedure below to remove the previous version's ADDE remote server, and install the McIDAS-X 2022 ADDE remote server. If any other service is using port 112, you will be notified during the procedure and be given the option of overriding it with the McIDAS ADDE service.
1. Log on to the workstation as root.
2. Change to the home directory for user mcidas.
3. Uninstall the previous version's ADDE remote server. Replace version# in the command below with the previous version number of McIDAS-X (2019, for example). If you used an account other than mcadde for your ADDE remote server, insert that account name in place of mcadde.
This step removes the modifications made to the Internet services daemon (xinetd or systemd on Linux and xinetd on OS X) configuration files, forces xinetd/systemd to reread its configuration files, and attempts to verify that xinetd/systemd is no longer listening for ADDE requests from McIDAS-X clients.
To install the McIDAS-X 2022 ADDE remote server, go to step 4. Otherwise, proceed to Removing the Previous Version of McIDAS-X.
4. Install the McIDAS-X 2022 ADDE remote server. If you use an account other than mcadde for your ADDE remote server, insert that account name in place of mcadde in the command below.
This step modifies the Internet services daemon configuration file(s) to be aware of the ADDE service, forces a reread configuration files, and attempts to verify that the daemon is listening for ADDE requests from McIDAS-X clients.
