Ubuntu for Internet servers On the Ubuntu installation disk you will find specialised software for databases, web serving, email hosting and DNS name serving, internet cacheing and directory services. ... Ubuntu can be installed in a minimal server configuration optimised for datacenter servers that will not be used as desktop machines.
Sounds like it's got what you need. If we're talking about web serving, it appears to use Apache 2 - I don't know if Apache 1.3 is available in the main distribution or only as an unsupported package.
Ubuntu certainly looks good. They've got clear goals, a business-like approach, good developers and a huge pot of cash to fund it all. I've ordered some CDs, most of which I'll donate to the local library and other such places.
