Nein, daran habe ich bislang nichts verändert - aber so sieht der Inhalt meiner .bashrc aus :
#
# ~/.bashrc
#
# If not running interactively, don't do anything
[[ $- != *i* ]] && return
alias ls='ls --color=auto'
PS1='[\u@\h \W]\$ '
#export http_proxy="http://USER:PASSWORD@HOST:PORT"
#export https_proxy="http://USER:PASSWORD@HOST:PORT"
#export ftp_proxy="http://USER:PASSWORD@HOST:PORT"
