Hm. "Network is unreachable" means that you have got a networking
problem not a database problem. You'll probably find that simple
commands like "ping localhost" don't work either. The problem could
be a DNS issue --- what does "nslookup localhost" say? If it comes
back with something reasonable, then you've got a kernel
misconfiguration issue, which I don't think I can help you with.
