Ah, so DNS is not working. you are getting failures when doing host lookups. But, minnie.tuhs.org is probably in your /etc/hosts file (it is in mine).
To summarise:
- you can connect to a host on port 8000 if you provide the IP address.
- You cannot connect to the same host on port 80.
- You cannot resolve hostnames via DNS
Can you try the following (this is the same test as before, but using ip addresses rather that host names):
www.abc.net.au:
www.abc.net.au via proxy.netspace.net.auCode:wget -v -t 1 http://202.6.74.88
minnie.tuhs.org via proxy.netspace.net.auCode:http_proxy=http://210.15.254.253:8080 wget -v -t1 http://202.6.74.88
Code:http_proxy=http://210.15.254.253:8080 wget -v -t1 http://131.244.9.101
