I like sub-script configure-proxy but if someone (like me) has blocked ftp connections, you can add one line:
export ftp_proxy="${http_proxy}"full script:
#!/bin/bash
display_multiline "
This installer needs to be able to download software from the Internet via
HTTP/HTTPS. If this server cannot directly access the Internet or is not
already configured to connect through a proxy, you will need to configure
your proxy settings now.
"
prompt_question_yes_or_no_default_no "Do you need to configure this server to connect to a proxy?" need_proxy
if [[ $need_proxy = 'y' ]] ; then
prompt_question_text_input "Proxy hostname or IP address" proxy_host
prompt_question_text_input "Proxy protocol" proxy_protocol "http"
prompt_question_text_input "Username (if any) used to authenticate with proxy" proxy_user
if [[ -z $proxy_user ]] ; then
proxy_pass=
else
prompt_question_password_input "Password used to authenticate with proxy" proxy_pass
fi
prompt_question_text_input "Port on which proxy is listening" proxy_port "1080"
if [[ -z $proxy_user || -z $proxy_pass ]] ; then
proxy_user_pass=
else

export http_proxy="${proxy_protocol}://${proxy_user_pass}${proxy_host}:${proxy_port}/"
export https_proxy="${http_proxy}"
export ftp_proxy="${http_proxy}"
