Re: [Veritas-bu] bpclntcmd and othersignoringnsswitch.conf?-RESOLVED (yes actually resolved this time)
I'd seen most of that but it is all related to Solaris which we don't use here. The file mentioned for Solaris ipnodes doesn't appear to exist for HP-UX or RHEL. (The nsswitch.conf file exists on all 3 though and as noted the HP-UX version does allow for an ipnodes line.) My MS Admin tells me that Windows always uses hosts first, WINS second and DNS last so there apparently isn't any equivalent to nsswitch.conf on Windows. -Original Message- From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Girish Jorapurkar Sent: Tuesday, May 03, 2011 4:02 PM To: Lightner, Jeff Cc: veritas-bu@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] bpclntcmd and othersignoringnsswitch.conf?-RESOLVED (yes actually resolved this time) http://www.brandonhutchinson.com/Solaris_10_ipnodes_caveat.html http://blogs.sun.com/superpat/entry/solaris_10_etc_hosts_gotcha http://download.oracle.com/docs/cd/E19455-01/806-0916/6ja8539c5/index.html Hmm... who knew (I did not) there is so much already known about this?! :) --- On Wed, 5/4/11, Lightner, Jeff wrote: > From: Lightner, Jeff > Subject: RE: [Veritas-bu] bpclntcmd and others > ignoringnsswitch.conf?-RESOLVED (yes actually resolved this time) > To: "Girish Jorapurkar" > Cc: veritas-bu@mailman.eng.auburn.edu > Date: Wednesday, May 4, 2011, 12:04 AM > I just checked my RHEL6 master and > the RHEL5 media server I'd tested before and neither of them > have ipnodes in /etc/nsswitch.conf.
