Overview


IP Tools is an interface that is located in the Status area of the administration dashboard. It helps the administrators in troubleshooting the connectivity issues and obtaining information about a particular host or IP address.

This article provides the functionalities of the following four tools which are available to be utilized by the Kerio administrators in the IP Tools interface:

  1. Ping
  2. Traceroute
  3. DNS Lookup
  4. Whois

Information


Ping


The Ping tool enables the users to test the connectivity between the firewall system and a remote host. To ping a host:

  1. Provide a hostname or IP address in the Target field. 
  2. Choose IPv4 or IPv6 as the Protocol.
  3. Start the ping and review the results in the Command output window.

Traceroute


The Traceroute tool outputs the entire routing path between the firewall system and a remote host. This enables you to identify the specific router that is responsible for latency or connectivity issues.

To traceroute to a host:

  1. Specify a hostname or IP address in the Target field.
  2. Choose IPv4 or IPv6 as the Protocol.
  3. Start the traceroute and review the results in the Command output window.

NOTE: The Resolve addresses to hostnames option provides the reverse lookup name of each address in the routing path. The hostname can give some indication of the responsible parties of each device in the routing path.

DNS Lookup


The DNS Lookup tool attempts to resolve the hostnames. You can use this tool to confirm if the firewall system can successfully resolve hostnames.

To look for a specific hostname:

  1. Specify the Name. 
  2. Choose nslookup or dig as the Tool.
    • The nslookup query tool provides a primary response.
    • The dig query tool returns additional details about the query, such as the round trip time, or if the response is authoritative.
  3. Select the Server.
    • localhost refers to the DNS forwarder feature.
    • The other addresses are taken from the DNS servers assigned to each of the network interfaces. 
  4. Select the query Type. 
  5. Start the query and review the results in the Command output window.

  1. Enter the domain name in the Host field.
  2. Click the Start button to perform the query.
