This should be the color code: Color Code Black 0;30 Blue 0;34 Green 0;32 Cyan 0;36 Red 0;31 Purple 0;35 Brown 0;33 Blue 0;34 Green 0;32 Cyan 0;36 Red 0;31 Purple 0;35 Brown 0;33

After you install Ubuntu Server 12.04 (host), then you install a virtual box guest (Windows 2008 Server x64 in my case) and install your services on the guest. You'll have to do the following to access your guest's web server: Windows Firewall ! Your guest does not enable port 80\8080 by default If that doesn't fix it already, try turning your guest's NIC into promiscuous mode: VBoxManage modifyvm "Win2008Server_x64" --nicpromisc1 allow-all This of course implies that Ubuntu iptables do allow port 80. If you have just installed the server then you have no rules what so ever and all connections are allowed by default so it iptables won't be an issue then. If you find the first step enough to resolve this, please mention it in a comment. Thanks.

I recently used this very nice online wizard tool to generate a MySQL configuration file for a dedicated server. The thing is that I enabled the option "SQL Strict Mode" which generated many helpful constraints but one, which was " ONLY_FULL_GROUP_BY ". I don't think many people would like to have this constraint but I know I didn't. Just open your my.cnf file, remove that constraint and restart your server .
