  • Ticket #6168 – Description

    initial v4  
    11When debugging without a serial port, network-based output would provide an alternative to re-typing screen output or taking pictures.

    3 As a proof of concept this patch adds UDP-based '''syslog-ng''' support ([http://datatracker.ietf.org/doc/rfc5424/ RFC5424], [http://datatracker.ietf.org/doc/rfc5426/ RFC5426]) to the boot loader. While UDP is potentially lossy, unidirectional broadcast of datagrams avoids server discovery/selection and it avoids a dependency on still-pending TCP support patches (#5240).

    55Output starts once the network stack is initialized - on ppc currently only when network-booting, before searching for boot volumes - and with #6166 patches until the last {{{malloc()}}} for kernel ELF sections.
