Maybe I am missing something here.. but what does 'sudo' have to do with DNS resolution? From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf Of Steve Clark Sent: Friday, December 10, 2010 7:44 AM To: CentOS mailing list Subject: [CentOS] sudo doing DNS lookup Hi, I have a confusing problem. I have two centos 5,5 boxes. Both have sudo.i386 1.7.2p1-9.el5_5 installed I am using the same sudoers file, but the one on box A keeps trying to do DNS lookups while the one on box B does not. How do I disable this DNS lookup? Thanks for any info. -- Stephen Clark NetWolves Sr. Software Engineer III Phone: 813-579-3200 Fax: 813-882-0209 Email: steve.clark at netwolves.com http://www.netwolves.com -------------- next part -------------- An HTML attachment was scrubbed...
