This sounds like motherhood and apple pie -- "We, the IETF, should know how to run each protocol and especially how to run protocols as a mixture. And we should floss daily and always call our granny on her birthday..." But, before this thread, how many people here even knew we were running proftpd? How many people on this list are operationally involved in running the ietf.org mail / dns / ftp / rsync / web / etc? Who has root on these boxes? Quick, name the box that mailman runs on. What version of apache run www.ietf.org?[0] I've been trying to stay out of this thread, but now that I've started commenting... Perhaps we should also consider the human time cost of this whole discussion -- so far there have been 65+ emails on this topic - each of these have taken a non-insignificant amount of time to write, and many many people have spent time reading them. Payscale.com claims the median pay for a Snr Network Engineer in the US is $91,226 per year, or ~$45 per hour[1] - how much has this whole conversation cost us?![2] W [0]: Yup, this is a trick question - but I'm guessing a fair number of people don't know why... [1]: This was the quickest / easiest number to find - I'm betting most people on the list earn significantly more than that... [2]: I'm choosing to a: make the issue worse by bringing this up, which will no doubt prolong the thread....and b: I refuse to let people use the same argument when I start talking about something that I happen to find interesting or entertaining. Like hypocrisy... or the writings of Jerome K Jerome... or cats... or the changing distribution of colors in paintings over time ( http://www.washingtonpost.com/blogs/wonkblog/wp/2015/04/06/the-colors-of-94526-paintings-since-1800-charted/?tid=sm_fb ). > >> The FTP server we are using (proftpd) places restrictions on how we >> store files in the file sytem that are much more constraining than >> the http and rsync daemons.

This is like putting rabid weasels in your pants, and later expressing regret at having chosen those particular rabid weasels and that pair of pants. ---maf
