Este artículo describe cómo instalar y configurar The Citrix Client en Slackware. Hoy en día este cliente es mejor conocido como el “Receptor Citrix”.

Al citar el sitio web de Citrix: “ Citrix Receiver es un software cliente fácil de instalar que le permite acceder a sus documentos, aplicaciones y escritorios desde cualquiera de sus dispositivos, incluidos teléfonos inteligentes, tabletas y PC ”. Suponiendo que, por supuesto, alguien (por lo general, la compañía de su empleador) ha configurado un servidor Citrix en algún lugar donde el receptor puede hacer sus conexiones remotas.

• El Citrix Receiver es un software exclusivo de binario. Por lo tanto, no debería sorprender que este software de Receiver sea solo de 32 bits. Debe ejecutar Slackware de 32 bits o Slackware de 64 bits con multilib añadido.
• El Citrix Receiver está vinculado a la biblioteca gráfica de widgets X-Window Motif solo para uso binario y comercial. Esto crea una incompatibilidad con la propia lesstif widget library de Slackware, una reimplementación gratuita de Motif. Debe eliminar el paquete lesstif e instalar un paquete de (open)motif o, de lo contrario, el Cliente Citrix no se ejecutará. Un paquete openmotif (openmotif es una versión gratuita no comercial de Motif) se puede encontrar aquí: http: //www.slackware.com/~alien/slackbuilds/openmotif/

On the Citrix web site, search for “linux client (32bits)”. At the moment of writing, the search path is:
http://www.citrix.com/downloads/ > “Citrix Receiver” > “Receiver for Linux” > “x86 client - requires OpenMotif v.2.3.1 (tar.gz version)”

Create a temporary directory if you want, and as root, extract the tarball and run the installer:

# mkdir icaclient
# cd icaclient/
# tar xvf  ~/downloads/linuxx86_12.1.0.203066.tar.gz

Run the “setupwfc” program and accept all the default values which it offers. If you do not want to use the default installation directory “/opt/Citrix/ICAClient/” then you will have to define the environment variable “ICAROOT” and point that to your custom installation directory.
The “setupwfc” program will ask you if you desire browser integration and integration with the KDE Desktop Environment. That is good to have so the answer you give is “yes”. As a result, the application links in your company's Citrix Server will automatically work.

  # ./setupwfc

The Citrix client/server communication uses SSL encryption. Your company may be using a SSL certificate for which the CA certificate is not yet known to the Citrix Client.

• When you see the following error message:

  You have chosen not to trust "Thawte Premium Server CA", the issuer of the server's security certificate (SSL error 61).

  then edit this file:

  /opt/Citrix/ICAClient/config/Trusted_Region.ini

  where your company's Citrix Server domain name must be added as trusted proxy:

  ; If you allow a proxy type (Secure or Socks) that uses a server,
  ; you will need to change the ProxyHost line below to indicate which 
  ; servers are trusted, for example:
  ; ProxyHost=,*.mycompany.com:*,*.mypartner.com:*
  ; 
  ProxyHost=,*.yourcompany.com:*

• Create a certificate directory if that did not yet exist:

  # mdir -p /opt/Citrix/ICAClient/keystore/cacerts

• Install the missing certificate (must have a “.crt” extension):

  # vi /opt/Citrix/ICAClient/keystore/cacerts/Thawte_Premium_Server_CA.crt

• You can for instance find this CA certificate here:

  /usr/share/ca-certificates/mozilla/Thawte_Premium_Server_CA.crt

If your Mozilla Firefox browser refuses to start the “icaclient” that can be caused by a non-standard language setting. At work I have a localized Linux (configured for dutch language, so my “LANG” environment variable is set to “nl_NL.UTF-8”). This is what I had to do in order to fix this issue:

• If the file “/usr/bin/firefox” is a script (recent versions of firefox are putting a real binary there instead) you must add this one line somewhere near the beginning:

   export LANG=C

• If the file “/usr/bin/firefox” is a binary file, then you can for instance modify its desktop file “usr/share/applications/mozilla-firefox.desktop” by changing the executable command

  Exec=firefox %u

  to:

  Exec=LANG=C firefox %u
