Appliance General FAQ

Q). Troubleshooting

See Hardware Appliance Installation

Q). What appliance versions are there

A). The following Swivel appliances exist:

Virtual Appliance version 2.1 for VMware, Hyper-V, XenServer running CentOS

Dell Swivel Appliance version 2.1 running CentOS

Virtual Appliance version 2 for VMware, Hyper-V

Dell Swivel Appliance version 2 running Redhat Linux

The below appliances are end of Life

Dell Swivel Appliance running Redhat Linux pre CMI

ID Appliance running the Engarde OS

ID Appliance running Redhat Linux

see also Appliance Versions FAQ

Q). What appliance version do I have?

The CMI shows the appliance version under Advanced Menu then Version information. For older appliances the following can be checked:

Check the login message from the console.

run the following command

 grep APPLIANCE_VERS /etc/pinsafe.conf|cut -d\= -f2

If not, inspect the /etc/pinsafe.conf file manually.

Other components can be found from the following commands on older appliances:

Apache Tomcat:

 ls /usr/local|grep apache|cut -d\- -f3

Java:

 ls /usr/java|grep jre|cut -d\e -f2

MySQL (if used):

 mysql --version|cut -d\  -f6|cut -d\, -f1

Webmin:

 cat /etc/webmin/version

Q). Can I use my Evaluation appliance in production

A). The Evaluation appliance is a stand alone appliance, so if a stand alone appliance is required, then this may be possible. If an A/A or A/P pair is required then new appliances will need to be deployed.

Q) How do I tell my appliance is synchronised

See the following article: MySQL Database How To Guide specifically Active/Active appliance replication synchronisation check]

Q). What appliance do I have? Am I running standalone, Active/Passive, Active/Active, or a DR?

A). A lot of installs appear to be the same from the external view, and may require command line access to determine the type.

Standalone: Running on its own using the internal Swivel data store. A Standalone appliance may be Hardware or VMware.

Active/Passive: These are mostly hardware appliances. Hardware HA pairs with a cross over cable between the secondary interface, it uses a Virtual IP address that switches from the Active machine to the standby machine when it is fails over and file replication to share data between systems, using a process called drbd. In this configuration there is only one Swivel instance to configure, the entire file system including the Swivel application automatically fails over. This system may not scale to more than two Swivel servers.

To see if is running in A/P mode run the following from the command line:

 cat /proc/drbd

Expected Results:

 drbd driver loaded OK; device status:

Active/Active: These may be hardware or VMware. Each Swivel appliance is able to receive authentication requests regardless of the state of the other. On the appliance this will be used with a MySQL database, although it would be possible to use another external Database. Using the Virtual IP address is optional. To verify it is in active/active mode, check from the Swivel Administration console to see if the MySQL database is being used and mode is synchronised. Configuation of the Active/Active is setup during the CMI Networking confiiguration.

DR or Slave: These may be hardware or VMWare. Here each Swivel appliance is able to receive authentication requests regardless of the state of the other. The appliance may appear to be Active/Passive if the deployment scenario directs all authentication requests to one Swivel appliance, although it is an Active/Active deployment. On the appliance a MySQL database is used, although it would be possible to use another external Database. To verify it is in DR or slave mode and not an Active server, check from the Swivel Administration console to see if the MySQL database is being used and mode is slave.

Q). Which video ports should be used?

A). The DELL appliances have onboard VGA cards but these are non functional when a DRAC card is installed in the PCI slot of the appliance.

Q). What are the default IP addresses of the appliance?

A). The following default IP addresses are used:

Standalone/DR ETH0 192.168.0.35

Primary of A/A ETH0 192.168.0.36 ETH1 172.16.0.1

Standby of A/A ETH0 192.168.0.37 ETH1 172.16.0.1

A/A VIP 192.168.0.38

Q). If I am not using the VIP what should I use instead?

A). Leave the default IP. Ensure that Heartbeat and Mon are set not to run at boot (this is the default)

Q). Does the appliance automatically adjust for daylight savings?

A). Yes the Swivel appliance will automatically adjust for daylight savings appropriate for the timezone.

Q). Can I upgrade a standalone appliance to an A/A appliance?

A). No, the appliance build is different and would need to be replaced by an A/A appliance pair.

Q). Can I install A/A appliances in separate subnets or locations?

A). If the VIP is being used then the Swivel appliance must be in the same broadcast domain, see VIP on PINsafe Appliances. If the Session Sharing is being used, then the Swivel appliances must be in the same multicast domain. If the VIP and Session Sharing are not used, then the servers may be in different subnets, with a direct link between the secondary Ethernet ports ETH1. It is not recommended but may be possible to put an A/A pair of appliances in different geographical locations, reliable links with adequate bandwidth must be in place to ensure the databases maintain synchronisation. The standard practice is to place an A/A pair at a single location and a DR appliance at a DR site for use if the primary site is not available.

Q). What Swivel Appliance Hardware Support is available?

A). The hardware support is provided by Dell and is 24 x 7 if the hardware is within the support contract time period, i.e has not expired. Dell usually perform remote-diagnostics and if it is required to send an engineer to site, the engineer will be on-site within 4 hours. Note this support is only valid for the country of sale, unless Swivel Secure have been notified in advance that the hardware has been shipped to a differing country. For more information contact Swivel Secure support.

Q). What is the Swivel Appliance Hardware Specification?

A). For the Hardware Appliance Specification see Hardware Appliance Specification

Q). Why does the localhost appear for TURing images?

A). INFO 127.0.0.1:Session start. The appliance has a proxy so TURing images may appear to come from the local address.
