Install OSS5.x Client PC


Intall NetAct client PC   

NetAct Start Page: https://login.r07.netact.sg.tac/netact/login.html Certificate Page: https://login.r07.netact.sg.tac/CertGenWeb/login.html Tier1 Sw Download: https://login.r07.netact.sg.tac/client_sw/


 Downloading  

and installing Tier 1 package:

in Windows in Linux

 Configuring

file associations  Checking browser settings  Downloading and installing certificates


Downloading and installing Tier 1 package in Windows  

  

Open your workstation web browser and enter the following URL: https:///client_sw/ where stands for the fully qualified domain name that has been assigned to the request dispatcher inside the LinAS cluster during the system installation. If not known, contact your system administrator. Click the Windows tier1 package link and download the Tier1 Tier1.exe exe file to a temporary folder in the user workstation. You are prompted with the following message: “Before installation please you have rights g to install software”. Enter OK to continue. check that y The JRE and ICA client applications are installed to the user workstation.

Downloading and installing Tier 1 package in Linux  

     

Open your workstation web browser and enter the following URL: https:///client_sw/ where stands for the fully qualified domain name that has been assigned to the request dispatcher inside the LinAS cluster during the system installation. If not known, contact your system administrator. Click the Linux tier1 package link and download the tier1 tier1_package.sh package sh file to a temporary folder in the user workstation. Find the folder where the file was saved, for example, cd /tmp. Change the file permissions: chmod 755 tier1 tier1_package.sh. package sh Install the tier1 software: ./tier1_package.sh. If there is a previous installation, you are asked to confirm that the previous version can be overwritten overwritten. Click Yes to use the SSL relay and to configure the port.


Create the file associations 

Open Windows Explorer and click Tools → Folder options → File Types, or the Internet browser used, for example, Edit → Preferences → Helper applications, and verify the following:  file type .jlnp is associated with the jawaws application  file fil ttype .ica i iis associated i t d with ith th the Cit Citrix i ICA Client Cli t E Engine i



If the associations have not been made, create them in the following way: To create the associations in Windows-based NetAct user workstations, select New/New Type.  Note: To create the associations in Windows-based NetAct user workstations you can use, for example, l Wi Windows d E Explorer l or IInternet t tE Explorer. l  Follow the steps below to create the file associations in Linux-based NetAct user workstations:  Start the web browser you want to use.  Select Preferences/Options…  Select Helper Applications/Application/File Types …  Add the MIME type “application/x-java-jnlp-file” for files with extension/suffix .jnlp and add as the application that the browser should invoke for this file type “/opt/Nokia/j2re1.4.2_12/javaws/javaws”.  Add the MIME type “application/x-ica” for files with extension/suffix .ica and add as the application that the browser should invoke for this file type “/opt/Nokia/ICAClient/wfica /opt/Nokia/ICAClient/wfica.sh sh”. 


Checking browser settings 

    

With the current default Internet Explorer browser settings you cannot launch jnlp files because of Microsoft Internet Explorer bug 812935. To overcome this problem, do the following adjustment to the browser settings: I Internet In I Explorer, E l select l T Tools. l In the Tools drop-down list, select Internet Options. In Internet Options, select Advanced. In Advanced, Advanced scroll down to Security and ensure that the option Do not save encrypted pages to disk is not selected. The security settings of the Internet Explorer can restrict the usage of some NetAct applications. Do the following adjustment to the IE browser settings to avoid getting the message “Your Your current security settings do not allow this file to be downloaded”. downloaded . In Internet Explorer, select Tools. In the Tools drop-down list, select Internet Options. In Internet Options, select Security. Click the Custom Level... button. Scroll down to Downloads.
