3.1 – Gateway
You can configure the gateway by editing gateway.conf file, here is a list of all options:
| Key | Value |
|---|---|
| bindAddr | Binding address, if you have multiple IP addresses and want to bind on one of them. If you have IIS running on same machine, you must ensure that it is not bound to the IP address & Port you want to use for the SparkGateway. You must set the bindings in the IIS Manager. However, it may also be necessary to change the HTTP service which by default listens on port 80 for all IP addresses. To do this you can use “netsh http add iplisten ipaddress=xxx.xxx.xxx.xxx” to instruct the HTTP service to listen on IP addresses not used by the SparkGateway. Then you can use port 80 on the unused IP Addresses with the SparkGateway. |
| ssl | Use HTTPS and WSS (WebSocket Secure Connection), default is false. If gateway is listening on 2 port, the parameter can be configured as: ssl = false, true |
| credSSP | Network Level Authentication, Value can be "true", "false" or "auto". Default is false. “true” will slow down the connection speed a little bit . It’s not necessary to use NLA if the gateway is connecting to internal RDP hosts only. It’s better to enable credSSP if you are using Microsoft RD Broker for load balancing. "auto" will connect without credSSP at the first time, reconnect with credSSP if the connection failed. |
| backlog | How many connections can be queued, default is 50. |
| user | Path of user configuration file (JSON format). |
| server | Path of RDP hosts configuration file (JSON format). |
| html | HTML root directory. |
| directoryIndex | Default page for html directory, default is "rdp.html;index.html". |
| license | Path of license file. |
| logfile | Path of log file. |
| maxbytes | Limit the maximum number of bytes to write to any one log file, default is 30M. |
| maxfiles | Log file rotation, the number of log files to use, default is 99. |
| logHttpHeader | If log http header, which may contains sensitive information. Default is true. |
| converter | Postscript to PDF converter, used for printing. Ghostscript is recommended: http://www.ghostscript.com/download/ Example: C:\\Program Files\\gs\\gs9.04\\bin\\gswin64c.exe |
| arguments | Arguments for converter. %1 is output pdf file name. %2 is input ps file name, they'll be replaced by program. Example: -dBATCH -dNOPAUSE -dUseCIEColor -dPDFSETTINGS=/printer -sDEVICE=pdfwrite -q -sOutputFile=%1 %2 |

| printerDriver | Printer driver name |
| shadowing | Shadowing switch (if allow joining a session), default is true. |
| cipherSuites | The cipher suites can be used by SSL encryption. You may want to use some good cipher suites only, for example: SSL_RSA_WITH_RC4_128_MD5, SSL_RSA_WITH_RC4_128_SHA, SSL_RSA_WITH_3DES_EDE_CBC_SHA, SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA, SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_DSS_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_DSS_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA You need to install Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files for AES 256 cipher suites. http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html |
| webAddress | HTTP server web address, used for OpenID login(redirection back). It’s also used on client side for getting real gateway address (client side may not know that if you are using multiple gateways for load balancing). |
| clientHost | Customize the host name of the client user. Default is the host name or ip address. You can use following variables in the string: ${hostName}: Host name of the gateway machine. ${hostAddress}: Host address of the gateway machine. ${sequence}: a sequence number ${__ip}: client host name or IP. ${ _PARAM_SESSION_ID}: Session GUID. ${ _PARAM_NUMERIC_ID}: Session 9 digit number ID. ${any parameter transferred from client side} e.g. clientHost = RS-${__ip}-${sequence} , the result will be RSClientHostName-0, RS-ClientHostName-1, … |

*Please always use absolute file path if you are running Gateway as a service.
You can also use config.html to configure gateway.conf. Use your browser navigate to: http://localhost/config.html.
