Rsync error on mirrors.ibiblio.org

Hi ibiblio team,

AARNet uses your gnu mirror as an upstream, but we’ve been having trouble getting a successful sync via rsync for the past few days.

The error appears (at least on the surface) to be related to the uid ‘ftp’ not being present on the server side:

$ rsync rsync://mirrors.ibiblio.org/gnu/

@ERROR: invalid uid ftp
rsync error: error starting client-server protocol (code 5) at main.c(1661) [Receiver=3.1.3]

The issue does not seem to be present if I list the top level:

$ rsync rsync://mirrors.ibiblio.org/

apache          Apache
CPAN            CPAN
CTAN            CTAN
eclipse         Eclipse
flightgear      Flightgear
gnu             GNU ftp software
mozdev          Mozdev
mozilla         Mozilla
...

The rsync client version on our end is 3.1.3 and our connections are sourced from 138.44.164.198

Please let me know if there are any other details I can help gather.

Blake.
