yum & proxy

[lists at tuxdoit.com (Mário Gamito)]

Hi,

I've just installed a server with CentOS 4.
This server is behind a proxy.

I'm trying to import the RPM key.

Already set http_proxy variable to:

export "http_proxy"=http://proxy.xpto.com:3128

Truth is, command

# rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-4

just leaves me hanged.

Any ideas ?

Warm Regards,
M?rio Gamito
