Display TCP/IP host names

Edit online

The dnsnames parameter defines how TCP/IP addresses are displayed in messages.

dnsnames=<on|off>
Description
Set the value to on to enable the display of TCP/IP addresses in messages as symbolic TCP/IP host names; these are obtained from a Domain Name System (DNS) query. This conversion makes the messages easier to read but might cause a significant reduction in performance. If the value is set to off TCP/IP addresses are displayed in messages in numeric form.

You can use the ctgservice command on Windows or ctgstart command on UNIX and Linux® with the -dnsnames option to override the value of dnsnames. For more information, see Command reference.

Note: The dnsnames parameter supersedes the nonames parameter.

This parameter is in the GATEWAY section of the configuration file.

Default value
The default for this parameter is off.
Configuration Tool
In the Configuration Tool, you can set the value of dnsnames to on by selecting the Display TCP/IP hostnames check box in the Logging tab of the Gateway daemon settings page.
