Citrix thin client interface

Just had  a problem solved under Lniux concerning use of the Citrix thin Client.
This is an application though which the Client is sent the video image
of applications which are actually running on a distant server.  For
thus accessing my company server,
there is one step additional under Linux.

The standard part is to download from
http://www.citrix.com/English/ss/downloads/details.asp?downloadId=3323&productId=186&c1=sot2755&c2=ost1349860
Version 10.6  English 6/28/07  1.8 mb .tar.gz
Though it states
------------------------
x86 client - requires OpenMotif 2.2.x
------------------------
OpenMotif does not appear to be essential, at least not on my Ubuntu system.

I made a working folder
$ mkdir icaclient
moved into it:
$ cd icaclient
unpacked the downlaoded tarball with:
$  tar zxf  ../en.linuxx86.tar.gz
which expanded:
$ ls
eula.txt  install.txt  linuxx86/  PkgId	readme.txt  setupwf

Setup within Ubuntu with:
$ sudo ./setupwf
just following the default choices presented.

The additional steps not needed under Microsoft concerned installation
of a security certificate from:
https://www.entrust.net/downloads/binary/entrust_ssl_ca.cer
a text file

 which I copied into a edit panel prepared with:
$  sudo gedit  /usr/lib/ICAClient/keystore/cacerts/entrust_ssl_ca.cer
and then saved .

Next move into that folder
$ cd   /usr/lib/ICAClient/keystore/cacerts/

and  two symbolic links are set:
$ sudo ln -s entrust_ssl_ca.cer entrust_ssl_ca.crt
$ sudo  ln -s entrust_ssl_ca.cer entrust_ssl_ca.der

with result:
/usr/lib/ICAClient/keystore/cacerts$ ls -l entrust*
-rw-r--r-- 1 root root 1740 2008-11-21 22:21 entrust_ssl_ca.cer
lrwxrwxrwx 1 root root   18 2008-11-21 22:26 entrust_ssl_ca.crt ->
entrust_ssl_ca.cer
lrwxrwxrwx 1 root root   18 2008-11-21 22:27 entrust_ssl_ca.der ->
entrust_ssl_ca.cer

Subsequently, using a Firefox  browser to access my workplace, the
Citrix application was automatically called, and all proceeded
automagically.

Generally, the workplace Server sends a Java script evoking on the
distant Citrix client, on your System.  Could be that other companies
may require other Security Certificates (not sure)

Credit goes to my company Info Tech staff, who revealed the need for
the manual entrust_ssl_ca.cer installation.
