Diagnostics¶

System diagnostics module enables executing basic system command, such as ping, netcat or traceroute.

To run a diagnostic utility, proceed as follows.

Select Settings > System.
Select the Diagnostics tab.
Each utility has its own tab. Select the desired one, provide the necessary parameters, and click Run to execute the command.

LDAP SEARCH

The LDAP Search utility allows the administrator to query an LDAP server for directory objects using specific filters and attributes.

The table below describes the available parameters required to perform a search.

Command/parameter	Description
Host	LDAP server IP address.
User name	Login of the user allowed to browse the directory.
Password	Password of the user allowed to browse the directory.
Domain	Directory domain to query.
Filter	Objects filtering parameter (eg. `(objectClass=*)`).
Attributes	LDAP search attributes.

PING

The Ping utility is used to verify the availability of a remote host by sending a series of ICMP packets.

The table below lists the available options for configuring the ping request.

Command/parameter	Description
Host	IP address or hostname of the remote system to be pinged.
Timeout	Maximum time to wait for a response, in seconds.
Bind address	Local IP address to use as the source of outgoing ping packets.
Numeric output only	Does not resolve host’s IP address to its mnemonic name.
Record route	Enables tracking packets’ route.

HOST

The Host utility checks whether a DNS server correctly resolves a hostname to its corresponding IP address.

The table below provides details of the available command and its purpose.

Command/parameter	Description
Host	Fully qualified domain name (FQDN) to be resolved via DNS.

NETCAT

The Netcat utility enables the administrator to establish a TCP connection to a specified host and port.

The table below outlines the available parameter used to perform this check.

Command/parameter	Description
Host	IP address or hostname of the remote system to connect to.
Port	TCP port number on the remote host to be tested.

TRACE ROUTE

The Trace Route utility traces the network path taken by packets between Fudo Enterprise and the specified host.

The table below describes the parameters that can be used to customize the trace operation.

Command/parameter	Description
Host	IP address or hostname of the target system for which the packet route should be traced.
Bind address	Local IP address from which the trace operation will be initiated.
Do not resolve hop addresses	Subsequent hop IP addresses are not resolved to mnemonic names.
Use ICMP ECHO instead of UDP datagrams	Enforces `traceroute` to use UDP packets instead of ICMP.
Firewall evasion mode	Enforces the same port numbers for UDP and TCP packets. Target port is not incremented with each packet sent.
Set the “don’t fragment” bit	Disables packet fragmentation in case the packet exceeds defined MTU (Maximum Transmission Unit) value defined for the network. Exceeding the MTU value results in an error.
