This section contains instructions on how to install or upgrade NetServer. The following details are available:


Before installing NetServer, you should have already installed your RADIUS AAA server or NAS, and configured and tested the appropriate databases to authenticate your own local users.

You should have the following information:

  • The IP address of the host on which you plan to install NetServer. This should be the Public IP Address registered to your iPass account which will be used to connect to the iPass AAA fabric. Your certificate cannot be validated until iPass places this IP address into our database.
  • The IP address, port numbers and secrets of RADIUS servers which forward requests to the netserver.
  • The iPass ISP Code given to your company when it signed up with iPass. If you do not have this code, please contact your iPass NetServer Installation Engineer.
  • Your username and password for the iPass FTP site where you will download the software. If you do not have these credentials, please contact your iPass NetServer Installation Engineer.

In addition, you should make sure that you have access to the following:

  • A Mail Transfer Agent (such as Sendmail) installed and configured to allow you to send the certificate request.
  • Root access on the NetServer host.

Supported RADIUS Attributes

NetServer 6.0.0 supports the following RADIUS attributes:

  • All attributes form RFC 2865 and 2866
  • From RFC 2869: EAP-Message, Message-Authenticator, NAS-Port-Id
  • From RFC 4372: Chargeable-User-Identity (CUI)
  • From RFC 2546: ms-mppe-send-key, ms-mppe-recv-key

Graceful Forwarding: NetServer authentication and accounting will drop attributes that are not listed in RFC 2865 and 2866, but packets are still forwarded.

NetServer Default Ports

  • SSL port=11811
  • Authorization port=11812(NetServer uses a different port than RADIUS)
  • Accounting port=11813
  • Proxy authorization port=11817
  • Proxy accounting port=11818

Installation Process

The installation process consists of downloading the installation file and then installing the software.


You will need to download NetServer installation file from our secure FTP site. Contact your iPass installation engineer for your FTP username and password.

To download the NetServer installation file:

  1. At a command line, type: ftp
  2. At the username prompt, type your FTP username.
  3. At the password prompt, type your FTP password.
  4. Type: cd NS/6.0.0
  5. Type: bin
  6. Type: get <correct version for your OS>
  7. When the download is complete, type: bye.
Directory names and filenames are case-sensitive.

Installing the Software

This guide uses the term <NS_Home> for the NetServer 6.0.0 installation directory. The default is /usr/ipass/netserver/current_version.

To install the NetServer 6.0.0 directories:

  1. The iPass Products directory /usr/ipass should be created and owned by root or the appropriate “ipass” service account with sudoer permission. If your partitioning scheme does not provide enough space for /usr/ipass, create a symbolic link for the /usr/ipass directory to the intended installation volume.
  2. Copy the downloaded NS 6.0.0 installation file “netserver_6.0.0_<platform>.tar.gz” under '/usr/ipass/',where <platform> is the platform of your NetServer.
  3. Type: cd /usr/ipass/
  4. Type: gunzip netserver_6.0.0_<platform>.tar.gz to uncompress the installation file.
  5. Type: tar -xvf netserver_6.0.0_<platform>.tar. By default, this will create a hierarchy in “/usr/ipass/netserver/6.0.0” with all the necessary directories and files. In order for NetServer to run correctly,you must keep the file hierarchy as it is installed.
  6. Run ./create_link script from the directory path “/usr/ipass/netserver/6.0.0/.scripts” to create a softlink /usr/ipass/netserver/current_version → /usr/ipass/netserver/6.0.0
  7. Type: ipassconfig.csh -conf under /usr/ipass/netserver/current_version/bin to generate file. For detailed information regarding configuration, refer to Configuration section. Once configuration is complete, your NetServer is ready to be started.
  8. Run script under /usr/ipass/netserver/current_vesrion/bin directory to create RC scripts.
  9. Review the End User License Agreement from the file “<NS_Home>/license.txt”.

Migration Tool

Migrating from NetServer 5.x to NetServer 6.0.0

If you are upgrading to NetServer 6.0.0 from version 5.x, the Migration Tool has to run manually post installation process. The Migration Tool will convert your old configuration file into the new adding newly added properties in 6.0.0, and copy certificates and keys from the old installation into KeyStores.

Manual Migration

  • Untar NetServer 6.0.0 build under /usr/ipass/ to create a hierarchy /usr/ipass/netserver/6.0.0

1. Migrating from NetServer 5.x to 6.0.0: Type ./ns_migration_tool.csh under /usr/ipass/netserver/6.0.0/bin

For example, cd /usr/ipass/netserver/6.0.0/bin and run : ./ns_migration_tool.csh. It will prompt you for the path to migrate files from. Enter NS5.x path /usr/ipass/netserver/5.x. It should migrate file,certs and keys from 5.x version to 6.0.0 and it will add new attributes to as below:

  • 'strip' flag is added for Routing Realms and for realms 'ipass' and 'ipasv' it is set to 'yes' by default and for other realms it is set to 'no' by default.
  • 'AdminKeyStoreProperty' is added to
  • All .pem keystore files are migrated to .keystore extension

2. Once migration is done run script from the path “/usr/ipass/netserver/6.0.0/.scripts” to create soft link( It will create soft link under “/usr/ipass/netserver/current_version”).

3. Run script from /usr/ipass/netserver/current_version/bin to create RC scripts.

The NetServerd Script

The script NetServerd is not included in the Migration Tool process, so command line options it contains will not be carried over to the new version of NetServer. This may trigger the following issues:

Non-Default Ports: The NetServer 6.0.0 Migration Tool assumes that your NetServer runs on the default port of 11811. If this is not the case, after you run the Migration Tool, you will need to edit the following attributes in the file:

  • Listener1=Type=RADIUS,Port=<port number>
  • Listener2=Type=RADIUSProxy,Port=<port number>
  • Dual-Homed Hosts: If NetServer 5.x runs on a dual-homed host, the Migration Tool may not bind NetServer to the correct IP address. You will need to check that the file reflects your correct IP address.
  • Port Settings: The migration tool will automatically migrate your previous port settings from NetServer 5.x to 6.0.0.

Rollback Procedure

If you need to roll back your NetServer 6.0.0 installation to a previous 5.x version, follow the appropriate procedures listed here.

These instructions assume that NetServer 5.x is installed in /usr/ipass/netserver/5.x, and NetServer 6.0.0 is installed in /usr/ipass/netserver/current_version.

To rollback NetServer 6.0.0:

  1. If necessary, stop NetServer 6.0.0 as follows:
    • Type: cd /usr/ipass/netserver/current_version/bin
    • Type: ./netserverd stop
    • Check if the process stopped by typing: ps -auxwww | grep netserver
    • If the process did not die, execute: ./netserverd kill
    • Verify that the process stopped by typing: ps -auxwww | grep netserver
  2. Change the softlink file /usr/ipass/netserver/current_version to point back to the previous NetServer directory /usr/ipass/netserver/<NS Version>, as follows:
    • cd to /usr/ipass/netserver/
    • rm current_version
    • ln –s /usr/ipass/netserver/5.x current_version
  3. Start the old NetServer:
    • cd to /usr/ipass/netserver/<NS Version>/bin
    • run ./netserverd start

Uninstalling NetServer 6.0.0

  • Type: cd /usr/ipass/netserver
  • Type: rm –rf 6.0.0

NetServer Binding

To bind to a local IP for outgoing requests to the Transaction Servers, you need to configure the LocalIpAddress attribute of your IpassServers property:

To view iPass Transaction Server information, type: <NS_HOME>/bin>ipassconfig.csh -help IpassServer

Sample format ofIpassServer:

IpassServer1 = name11=value11,name12=value12,…

IpassServer2 = name21=value21,name

See the Property Glossary for more information on configuring this value.
