a puzzle, maybe or maybe not trinity-related

hi, folks. this is a puzzle; it's something that has happened occasionally for years but now has become frequent enough to be an annoyance, and i do not know enough about the mechanisms involved even to begin to troubleshoot it. here's what happens: i am going merrily along and doing my work when i send an email message or go to a webpage and get errors that the host could not be found -- the usual dns error. when this happens i use the handy system settings network configurator and invariably discover that all the nameservers that i have listed are now gone. i presume that this application writes to /erc/resolv.conf (which is now a link to a resolv.conf someplace else, in /run/resolv.conf, which is heaven knows where but i suppose is one of those virtualized filesystems the boys are so proud of). anyway, i usually keep three domain nameservers there, just in case one goes down. something is causing them to disappear. i haven't fiddled with this stuff since resolv.conf was hard-coded such that you'd su root, edit /etc/resolv.conf, save the file, and be happy evermore. but now the file says not to edit it because it will be overwritten anyway. so. any guesses as to what might be making my list of nameservers disappear? that failing, any good recipe for troubleshooting it to see who is eating my nameservers? and if not that, is there anyplace i can put them so that they won't get overwritten? thanks very much and merry christmas, everybody! -- dep The shortest distance between you and playing great acoustic guitar: the great new instructional DVDs from Marjorie Thompson, available at www.MarjorieThompson.com
