[jira] [Updated] (GUACAMOLE-506) Printing does not work via HTTP,
only via websocket
[ https://issues.apache.org/jira/browse/GUACAMOLE-506?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jonathan Hunter updated GUACAMOLE-506:
--------------------------------------
Description:
Printing does not work (for me, at least) when using guacamole via an Apache reverse proxy *in HTTP mode*. I think that this counts as a bug - since everything else i.e. normal interactive use of guacamole RDP/VNC/SSH/etc. sessions work fine in this configuration, i.e. without websockets, just http reverse proxying.
The following two steps got printing going for me, but I think printing _should_ work via HTTP...
* Install Apache's mod_proxy_wstunnel (on Debian this is 'sudo a2enmod proxy_wstunnel')
* Add a line in Apache's config to websocket-proxy the relevant URL. (Note that this line must come *before* the config entry that proxies the rest of guacamole, since Apache's ProxyPass command operates on a first match wins basis.)
(I did look at Chapter 4 of the documentation, and in particular the 'Proxying with websocket' section, but I found I did not need the ProxyPassReverse statement shown there; nor did I need to place it within a <Location> section, in my config at least.)
My Apache config now looks like this:
{quote}{{ ProxyPass /remoteaccess/websocket-tunnel {color:#d04437}ws{color}://docker.host:5678/guacamole/websocket-tunnel}}
{{ ProxyPass /remoteaccess/ {color:#d04437} {color}[{color:#d04437}http{color}://docker.host:5678/guacamole/]}}
{quote}
and printing now works perfectly.
