We have an automatic proxy server configuration setup, and I can use a web browser but ping/curl are failing; it looks like a DNS resolution problem.
When I do:
URLGRABBER_DEBUG=1 yum check-update
Everything seems peach until this:
NSS error -8172 (SEC_ERROR_UNTRUSTED_ISSUER) Peer's certificate issuer has been marked as not trusted by the user.
I have tried a few things, but I'm no network Jedi; could someone with a better understanding of the Force help me out, here?
