Installing the McIDAS-X 2022.1 ADDE Remote Server

If this workstation has data that you want to make available to users on other workstations via ADDE, the ADDE remote server must be installed. If the remote servers are working correctly under the previous version of McIDAS, or if the workstation does not have such data, proceed to Removing the Previous Version of McIDAS-X. If the remote servers are not working correctly or if you need to install the servers for the first time on this workstation, install the McIDAS-X 2022.1 ADDE remote server below.

Notes:

The 2022.1 ADDE remote server uses port 112 for gzip-compressed, uncompressed and compressed 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 2022.1 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 in to a shell as root using command sudo bash.

2. Change to the home directory for user mcidas.

Type:  cd  ~mcidas

3. Uninstall the previous version's ADDE remote server. Replace version# in the command below with the previous version number of McIDAS-X (2021.1, for example). If you used an account other than mcadde for your ADDE remote server, insert that account name in place of mcadde.

Type:  sh  ./mcinetversion#.sh  uninstall  mcadde

This step removes the modifications made to the Internet services daemon configuration files (xinetd or systemd), forces a reread of the configuration files, and attempts to verify that it is no longer listening for ADDE requests from McIDAS-X clients.

To install the McIDAS-X 2022.1 ADDE remote server, go to step 4. Otherwise, proceed to Removing the Previous Version of McIDAS-X.

4. Install the McIDAS-X 2022.1 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. The optional :mcgroup (including the colon separator) is required when using systemd.  It specifies the group membership for the service, and the mcadde user must belong to this group. You can list the groups that contain the mcadde user with the command groups mcadde. You may also use a numeric GID.

Type:  sh  ./mcinet2022.1.sh  flag install  mcadde:mcgroup

where flag is the optional flag described below.

This step checks for the existence of the Internet services daemon systemd or xinetd.  It then modifies the configuration files to make the daemon aware of the ADDE service, forces the daemon to reread its configuration files, and attempts to verify that the daemon is listening for ADDE requests from McIDAS-X clients.

If you have installed the ADDE remote server and want to make datasets that are accessible to McIDAS-X client workstations, go to Appendix I, McIDAS-X Site Administration and Management and its Acquiring and Naming Data on a Remote Server page for more information.
