You know, I've seen this kind of thing result from having, for example, dns (or nis) listed before files in nsswitch.conf, and then the dns server becomes unavailable.
right: hosts: files dns wrong: hosts: dns files Note this effect can be duplicated (when the dns server becomes unavailable) if you have fully-qualified domain names listed in certain configuration files and only the short name (or no name at all!) in /etc/hosts, even if nsswitch.conf is right. ok r. > -----Original Message----- > From: Ron Foster at Baldor-IS [mailto:[EMAIL PROTECTED] > Sent: Monday, April 07, 2008 3:11 PM > To: LINUX-390@VM.MARIST.EDU > Subject: Re: Linux Guest recovery at Sungard not going well > > Peter, > > It bothers me that you brought up a SLES10 system that did > not have an NFS mount and > it still did not give you a logon prompt.
