Dnsmasq¶

Overview¶

EGSE Host comes with preinstalled instance of dnsmasq (https://thekelleys.org.uk/dnsmasq/doc.html) that serves as TFTP server for Board along with DNS proxy.

TFTP server¶

Bootloader running on DPU can use TFTP server to fetch operating system files from EGSE Host. This approach is particularly useful during development, as there is no need to re-write persistent memory on each image change. Provided TFTP server is available at IP address of EGSE Host:

TFTP server gives access to files stored in /var/tftp directory. By default, server permits both reads and writes.

DNS proxy¶

EGSE Host acts as DNS proxy for Board allowing it to resolve Internet domain names. DHCP server automatically provides necessary configuration to DPU, without any need for manual configuration.
