What version of OL6 are you using? 6.0, 6.1, 6.2, 6.3 or 6.4?
What adapter type are you using in VirtualBox: NAT or bridged adapter?
Do you need a HTML proxy?
I can't put the content of /etc/yum.repos.d/public-yum-ol6.repo because it is on VB...
I don't understand this sentence.
wget isn't installed, so I can't do that, but my /etc/yum.repos.d/public-yum-ol6.repo looks like http://public-yum.oracle.com/public-yum-ol6.repo.
Version of OL6 is 6.4 and adapter type is bridged adapter / PCnet Fast III (Am79C973)
Version of VB is 4.2.14 r86644 and I am using openSUSE 12.3
I can't copy/paste the content of /etc/yum.repos.d/public-yum-ol6.repo here on the forum... if you understand me.
