# [NAME](#NAME)

guacd - Guacamole proxy daemon

# [SYNOPSIS](#SYNOPSIS)

**guacd** \[**-b** *HOST*] \[**-l** *PORT*] \[**-p** *PID FILE*] \[**-L** *LOG LEVEL*] \[**-C** *CERTIFICATE FILE*] \[**-K** *KEY FILE*] \[**-f**] \[**-v**]

# [DESCRIPTION](#DESCRIPTION)

**guacd** is the Guacamole proxy daemon used by the Guacamole web application and framework. As JavaScript cannot handle binary protocols (like VNC and remote desktop) efficiently, a new text-based protocol was developed which would contain a common superset of the operations needed for efficient remote desktop access, but would be easy for JavaScript programs to process. **guacd** is the proxy which translates between arbitrary protocols and the Guacamole protocol.

# [OPTIONS](#OPTIONS)

[**-b** *HOST*](#b)

Changes the host or address that **guacd** listens on.

[**-l** *PORT*](#l)

Changes the port that **guacd** listens on (the default is port 4822).

[**-p** *FILE*](#p)

Causes **guacd** to write the PID of the daemon process to the specified file. This is useful for init scripts and is used by the provided init script.

[**-L** *LEVEL*](#L)

Sets the maximum level at which **guacd** will log messages to syslog and, if running in the foreground, the console. Legal values are **trace,** **debug,** **info,** **warning,** and **error.** The default value is **info.**

[**-f**](#f)

Causes **guacd** to run in the foreground, rather than automatically forking into the background.

[**-v**](#v)

Causes **guacd** to simply print its version information and exit.

# [SSL/TLS OPTIONS](#SSL/TLS_OPTIONS)

If libssl was present at the time **guacd** was compiled, it will contain SSL/TLS support, and connections between the web application and **guacd** can be encrypted if a certificate file is given.

When using a chain of certificates, you must append the additional certificates to your server certificate. This can be done easily with the standard **cat** command. Beware that the certificate for **guacd** *must* be the first certificate in the file.

[**-C** *CERTIFICATE FILE*](#C)

Enables SSL/TLS using the given certificate file. Future connections to this instance of **guacd** will require SSL/TLS enabled in the client (the web application). If this option is not given, communication with guacd must be unencrypted.

[**-K** *KEY FILE*](#K)

Enables SSL/TLS using the given private key file. Future connections to this instance of **guacd** will require SSL/TLS enabled in the client (the web application). If this option is not given, communication with guacd must be unencrypted.
