Citrix Client On Ubuntu


Chronogical Blog Entries:

Recently, I installed Citrix client on Ubuntu Hardy Heron. The install went quite smoothly. At the time of writing I found the latest tarball called en.linuxx86.tar.gz, on the Citrix site.

This tarball is a little unorthodox. The actual setup script is in the root folder. To run it, I copied it to a folder (called /usr/dwn) and then used the sudo -i command to assume super user privileges. I then entered these commands:
# check that the file /usr/dwn/en.linuxx86.tar.gz exists.
cd /usr/dwn
ls -l en.linuxx86.tar.gz
# make a target folder and unpack it.
mkdir citrix
cd citrix
tar xvfz ../en.linuxx86.tar.gz
./setupwfc

A series of simple instructions ensued. I chose "1" to install, and accepted the license. I then chose "y" to integrate with KDE or GNOME, and quit

This setup configures the client to work with Firefox on Ubuntu.

Next I restarted Firefox and logged into the Citrix metaframe server site and the authentication worked beautifully. Everything seemed fine and dandy. However when I tried to access any of the applications, Firefox responded with a weird (and rather obscure) error like the following:
You have chosen not to trust "Foo Bar" The issuer of the server's security certificate (SSL error 61)

I searched /usr for certificates (*.crt) and discovered one that looked like my Foo Bar certificate, in the folder /usr/share/ca-certificates/mozilla/.

It turns out that with the Citrix plugin installed, Firefox version 3 on Ubuntu Hardy Heron stores all the certificates in that folder. However the Citrix client expects certificates to be stored in /usr/lib/ICAClient/keystore/cacerts.

I resolved the problem by creating a symbolic link as follows:
cd /usr/lib/ICAClient/keystore/cacerts
mv -i * /usr/share/ca-certificates/mozilla/
cd ..
rmdir cacerts
ln -s /usr/share/ca-certificates/mozilla/ cacerts

Now the Citrix Client worked perfectly.

The above procedure also worked on Kubuntu.

Note: Substitute the name of your target Citrix certificate for Foo Bar, if you are experiencing similar problems.
