Connecting to Remote Servers
You can control remote instances from a Telnet session, from the Remote System Access submenu on the InterSystems IRIS® launcher on Windows, or from a URI generated from the web server and instance information.
To use the utilities on the Remote System Access submenu for a remote instance:
Define a remote server connection to add the server to the preferred server list.
Click the InterSystems IRIS launcher and point to Remote System Access.
Point to a launcher utility and then click the server name.
You may also connect to a remote instance of InterSystems IRIS from a Telnet session:
Click the InterSystems IRIS launcher and point to Remote System Access.
Click InterSystems IRIS Telnet, connect to the remote server, and log on to the InterSystems IRIS system with your username and password. Alternatively, if the server is on the preferred server list, point to Terminal and then click the server name.
You can remotely log into an InterSystems IRIS instance on any supported platform from a terminal running on a PC or from any workstation client capable of running Telnet. This client may have only utilities and not an InterSystems IRIS server instance. The version of InterSystems IRIS on the client machine in most cases, must be the same or a later version of the InterSystems IRIS system it manages.
On the macOS platform you can also use SSH from a command prompt on Windows to connect to your macOS machine and then connect with the following command:
sudo /sbin/service telnet start
You can also use Web Server Pages with a remote web server. This can be used to manage an InterSystems IRIS instance using the Management Portal.
When connecting to the Management Portal or Documentation choices on the Remote System Access menu, you can bookmark the generated URIs and return to these pages on your web server as long as the remote instance is running.
If you are using the Internet Explorer web browser you may need to adjust the Local intranet security settings to properly connect to remote servers.
Define a Remote Server Connection
To use the InterSystems IRIS launcher utilities or other InterSystems IRIS applications on a remote server, the server must be on the connection list in the InterSystems IRIS Server Manager. This is a list of remote servers you have previously defined to which you can quickly connect. A remote server is defined with an IP address for a unique server and a TCP port, which is an instance of InterSystems IRIS on that server.
The InterSystems IRIS superserver must be running on the remote machine and its port must be open on your firewall to use the InterSystems IRIS launcher utilities on that system.
For security reasons, username and password are not stored with the remote connection information.
To define the remote server:
From the InterSystems IRIS launcher menu, point to Preferred Server, and click Add/Edit to open the InterSystems IRIS Server Manager. (On Windows systems, you must have Administrator privileges to take this step.)
Click Add to open the Add Connection dialog box.
Fill in the fields as described in the following table and click OK. Each field is required unless otherwise indicated.
|Server Name||A descriptive phrase that identifies the server; it is what appears as a selection in the InterSystems IRIS launcher.|
|IP Address||The IP address, host name (if you have a DNS server) or the fully qualified domain name (FQDN) of the remote server. InterSystems IRIS accepts any legitimate name reference for the remote server.|
|Port||The port number of the superserver. The default port number is 1972.|
|Telnet Port||The port number of the telnet connection. The default port number is 23.|
|Web Server IP Address||Optional – The IP address of the web server you wish to use to manage this InterSystems IRIS instance. Defaults to IP Address if not specified. See Using Optional Server Fields for more information.|
|Web Server Port||The port number of the web server. The default port number is 52773.|
|CSP Server Instance||Optional – The InterSystems IRIS instance name to which you want to connect if you are configuring one web server to connect to multiple InterSystems IRIS instances. See Using Optional Server Fields for more information.|
|HTTPS||Whether or not links from the InterSystems IRIS launcher use HTTPS.|
Choose Kerberos1 or Password 2.
|Connection Security Level||For Kerberos 1 only. Choose either Kerberos, Kerberos with Packet Integrity, or Kerberos with Encryption.|
|Windows InterSystems IRIS Telnet Server||For Kerberos 1 only. Select this check box if you are defining a connection to a Windows server.|
|Service Principal Name||For Kerberos 1 only. This field is pre-filled with the recommended service principal name format “cache/<FQHN>” (FQHN is the fully qualified host name) for the IP address you enter.|
|Comment||Optional – A description of the remote server.|
1 See the Kerberos Authentication for details on the use of these fields.
2 See the Instance Authentication for information about password-based authentication in InterSystems IRIS.
Using Optional Server Fields
If you plan to use a web server that exists on a separate machine from the InterSystems IRIS instance you are managing, enter the IP address of the web server machine in this field. Defaults to IP Address if not specified.
If you are configuring one web server to connect to multiple InterSystems IRIS instances, enter the InterSystems IRIS instance name to which you want to connect in the CSP Server Instance field.
For example, if you have an IIS web server installed on a Windows machine and you also install two instances of InterSystems IRIS, iris1 and iris2, by default you manage each instance with its own private Apache web server that is installed as part of InterSystems IRIS.
However, you can also manage both instances from the public IIS web server by changing the Web Server Port (80 by default for IIS) and specifying iris1 and iris2 in the CSP Server Instance field when creating a server definition for each instance. This automatically creates virtual directories /iris1 and /iris2 on the public web server that point to the corresponding InterSystems IRIS instances.
When you enter a value in the CSP Server Instance field and select the Management Portal on the launcher for this server, the URI is formed as follows:
http://<web srvr addr>:<web srvr port>/<csp srvr inst>/csp/sys/UtilHome.csp
This places the instance name before the “/csp/sys/UtilHome.csp” portion of the URI and generates the following URIs for the two instances in the example.
If you plan to use InterSystems IRIS development tools and CSP applications remotely or control multiple instances from one web server, perform the advanced configuration steps described in the Advanced Web Server Configuration section.
Advanced Web Server Configuration
For some InterSystems IRIS features to function properly on a remote connection, you must configure some additional web server settings on the remote instance.
From the web server machine, point the Management Portal to the remote InterSystems IRIS server instance and configure the following settings from the Startup Settings page of the Portal (System Administration > Configuration > Additional Settings > Startup):
WebServerName — The DNS name or IP address of the web server that is configured for use with InterSystems IRIS tools (equivalent to the Web Server IP Address setting).
WebServerPort — The port number of the web server (equivalent to the Web Server Port setting).
WebServerURLPrefix — The name of the InterSystems IRIS server instance (equivalent to the CSP Server Instance setting).
For more information on complex configurations, see the Web Gateway Guide.
