Resolving hostnames locally


Resolving hostnames locally enables you to display hostnames in the log files for frequently used hosts, without having to rely on a DNS server. The known IP address - hostname pairs are stored locally in a file. In the log messages, AxoSyslog will replace the IP addresses of known hosts with their hostnames. To configure local name resolution, complete the following steps:


  1. Add the hostnames and the respective IP addresses to the file used for local name resolution. On Linux and UNIX systems, this is the /etc/hosts file. Consult the documentation of your operating system for details.

  2. Instruct AxoSyslog to resolve hostnames locally. Set the use-dns() option to persist_only.

  3. Set the dns-cache-hosts() option to point to the file storing the hostnames.
