If the admin console is unavailable, you can use the serial port console to perform some troubleshooting operations, such as use ping and traceroute commands, view logs, create system snapshots, and perform configuration rollbacks and factory resets.

Using Policy Tracing

It is common to encounter a situation where the system denies a user access to the network or to resources, and the user logs a trouble ticket. You can use the policy tracing utility and log to determine whether the system is working as expected and properly restricting access, or whether the user configuration or policy configuration needs to be updated to enable access in the user's case.

To create a policy trace log:

1.Select Maintenance> Troubleshooting > User Sessions > Policy Tracing to display the configuration page.

Policy Tracing Configuration Page shows the policy tracing configuration page for Ivanti Connect Secure.

Using the Simulation Utility

Ivanti Connect Secure allows you to troubleshoot problems by simulating the events causing the problem. Using the Maintenance > Troubleshooting > User Sessions> Simulation page, you can create virtual user sessions without requiring actual end users to sign in to the device and recreate their problems. In addition, you can also use the Simulation tab to test new authentication and authorization policies before using them in a production environment.

To use the simulator, you must specify which events you want to simulate (for example, you can create a virtual session in which "John Doe" signs into the "Users" realm at 6:00 AM from an Internet Explorer browser). Then, you must specify which events you want to record and log in the simulation. You can log three major types of events to the simulation log:

•Pre-Authentication - The system events that are captured will not include any other system related events. Events are merely used as a filtering mechanism to reduce the number of logs and highlight the problem.

•Role Mapping - The system events that are captured will not include any other system related events. Events are merely used as a filtering mechanism to reduce the number of logs and highlight the problem.

•Resource Policies - The system events that are captured will not include any other system related events. Events are merely used as a filtering mechanism to reduce the number of logs and highlight the problem.

To simulate a user session:

1.In the admin console, choose Maintenance > Troubleshooting > User Sessions > Simulation.

Simulation Configuration Page shows the configuration page for Ivanti Connect Secure.

2.In the Query Name field, enter a name for the query.

3.In the Username field, enter the username of the user whose experience you want to simulate. Note that you may use a wildcard character (*) in place of a username.

4.From the Realm drop-down menu, select the realm of the user whose experience you want to simulate.

5.If you want to determine whether to apply a specific type of resource policy to a user's session, enter the specific resource you want to simulate in the Resource field and select a policy type from the Resource drop-down list. Then:

•If you want to determine whether a user can successfully sign in to the device, select the Pre-Authentication check box.

•If you want to determine whether a user can successfully map to a specific role, select the Role Mapping check box. Note that this option controls whether role mapping results are logged to the simulator log, not whether to run role mapping rules. The system always runs role mapping rules, even if you do not select this check box.

•Specify the types of policies you want to log using the check boxes in the Events to Log section.

For example, if you want to test whether a user can access the Yahoo web site, enter "http://www.yahoo.com" in the Resource field, select Web from the drop-down list, and select the Access check box in the Events to Log section.

6.In the Variables section, use a combination of text and variables to create a custom expression that reflects the exact same values as in the real session of the user who is facing a problem. For example, if you want to create a session in which the user signs in to the device at 6:00 AM, enter "time = 6:00 AM" in the Variables field. For complete instructions on how to create a custom expression. You may also view the syntax for a given variable by clicking the arrow next to it in the Variables Dictionary.

If you fail to create a custom expression that includes the virtual user's IP address, the system uses your current IP address instead. Also note that if you use the role variable to specify the role of the virtual user (for example, role="Users"), the system ignores results from role mapping rules and assigns the virtual user to the role(s) you specify.

7.Choose one of the following options:

•Run Simulation-Runs the specified simulation and creates an on-screen log file.

•Save Query-Saves the query.

•Save Query and Run Simulation-Runs the specified simulation and also saves it for later use.

8.After running the simulation, choose Save Log As to save the simulation results to a text file.

Using the Session Recording Utility

You can use the Session Recording utility to record a trace file that lists a user's actions when accessing a resource or connecting to a client/server application. You do this to troubleshoot issues users might report regarding the Web access or client access.

When you start recording a trace file, the system signs out the specified user and then starts recording all user actions after the user signs in again and is authenticated. Note that the system notifies the user after authentication that user actions are being recorded.

To record a trace file:

1.In the admin console, choose Maintenance > Troubleshooting > User Sessions >Session Recording.

Session Recording shows the session recording page.

2.Enter the username of the user whose session you want to record.

3.Select the Web (DSRecord) check box to record the user's web session and then select the Ignore browser cache check box if you want to ignore cached copies of the problem web site, which the system would not otherwise record as a part of the trace file (optional).

4.Select the Client/Server (for JCP) check box to record Java Communication Protocol client/server application sessions (optional).

5.Click Start Recording. The system signs out the user.

6.Instruct the user to sign in again and browse to the problem web site or connect to the client/server application.

7.Click Stop Recording.

8.Download the trace file(s) from the Current Trace File section:

•Click the DSRecord Log link to download the Web trace file.

•Click the JCP or NCP Client-Side Log link to download the client/server application trace file.

9.E-mail the file(s) to Ivanti Support for review.

Network Troubleshooting Commands Configuration Page - Ivanti Connect Secure

The following table lists the Network Troubleshooting Commands Configuration Guidelines:

Settings	Guidelines
Command	Select a network troubleshooting command: Ping/Ping6-Use the ping command to verify that the system can connect to other systems on the network. In the event of a network failure between the local and remote nodes, you do not receive a reply from a pinged device. In that case, contact your LAN administrator for help. The ping command sends packets to a server and returns the server response, typically a set of statistics including the target server's IP address, the time spent sending packets and receiving the response, and other data. You can ping unicast or multicast addresses, and you must include the target server name in the request. Select ping to ping an IPv4 address or hostname. Select ping6 to ping an IPv6 address or hostname. Traceroute/Traceroute6-Use the traceroute command to discover the path that a packet takes from Ivanti Connect Secure to another host. Traceroute sends a packet to a destination server and receives an ICMP TIME_EXCEEDED response from each gateway along its path. The TIME_EXCEEDED responses and other data are recorded and displayed in the output, showing the path of the packet round-trip. Select traceroute to target an IPv4 address or hostname. Select traceroute6 to target an IPv6 address or hostname. NSLookup-Use NSlookup to get detailed information about a name server on the network. You can query on several different types of information, including a server's IP address, alias IP address, start-of-authority record, mail exchange record, user information, well-known services information, and other types of information. ARP-Use the arp command to map IP network addresses to the hardware addresses. The Address Resolution Protocol (ARP) allows you to resolve hardware addresses. To resolve the address of a server in your network, a system sends information about its unique identifier to a server process executed on a server in the intranet. The server process then returns the required address to the client process. AvgRTTs-Use AvgRTTs to display the average round-trip time (RTT) to the localhost. Portprobe-Display the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP) port status (open or closed).






Target server	Specify the IP address or hostname for the target server.
Interface	Select the interface from which to send the command.
VLAN Port	Select the VLAN through which the connectivity needs to be checked.
Output	Displays command output.

Troubleshooting TCP and UDP Port Status

Problem	Description: The system makes several connections to back-end servers using various port numbers. If communication between the system and the back-end servers stops, it can be difficult to determine the source of the problem.
Solution	You can use the Portprobe command to display the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP) port status (open or closed).

Only the system internal ports, management port and internal VLAN ports support the Portprobe command.

A TCP port can be closed under two conditions:

•The system sends a connection request to the back-end server port and the back-end server closes the connection (sends an RST packet).

•The connection request times out because the back-end server is not found, or the back-end server is too busy to respond to the connection request.

If either of these conditions occurs, the system sends a ping command to the back-end server. If the ping command is successful, the back-end server is considered reachable, but the back-end server port is closed. If the ping command fails, the back-end server is considered unreachable.

For UDP ports, the system sends a UDP datagram with a ping to the back-end server port. If the back-end server responds with Internet Control Message Protocol (ICMP) port unreachable or ICMP unreachable, the back-end port is considered unreachable. If the back-end server responds with ICMP host unreachable then the back-end server is considered unreachable.

To troubleshoot the TCP or UDP port:

1.Select Maintenance > Troubleshooting > Tools > Commands.

2.Select the Portprobe command.

3.Select either TCP or UDP.

4.Enter the target server and port number. You can enter an IP address, hostname or FQDN for the target server.

5.Enter the probe count. This is the number of times the system attempts to communicate with the back-end server port. The default for TCP is one; the default for UDP is five.

6.Enter the probe timeout. This is the number of seconds the system waits for a response from the back-end server port.

7.Select either the internal port or the management port. If the management port is not configured, it is not displayed.

8.If using an internal port, select the internal VLAN port from the list.

9.Click OK.

Successful TCP Port Probe show an example of a successful and an unsuccessful port probe.
