Hi, I've just installed a CentOS 4.4 and i'm behind a proxy with authentication. Does anyone know the parameters for the environment variable "http_proxy" so i can make a "yum update" ? Usually i'd do a $ export http_proxy="proxy.domaion.foo:3128" but this is not the case of an authenticated proxy. Any help would be appreciated. Warm Regards, Mário Gamito
