From fe50f1a9292b34e168b35453f2cfc2aee2ca4843 Mon Sep 17 00:00:00 2001 From: Viacheslav Hletenko Date: Tue, 2 Jul 2024 05:22:59 +0000 Subject: T6486: T6379: Rewrite generate openvpn client-config This command helps to generate users `.ovpn` files Rewrite `generate openvpn client-config` to use Config() It needs to get the default values as `ConfigTreeQuery` is not supporting default values. Fixed "ignores configured protocol type" if TCP is used Fixed lzo, was used even if lzo not configured Fixed encryption is not parse the dict --- src/op_mode/generate_ovpn_client_file.py | 113 +++++++++++++++++-------------- 1 file changed, 64 insertions(+), 49 deletions(-) (limited to 'src/op_mode') diff --git a/src/op_mode/generate_ovpn_client_file.py b/src/op_mode/generate_ovpn_client_file.py index 2d96fe217..974f7d9b6 100755 --- a/src/op_mode/generate_ovpn_client_file.py +++ b/src/op_mode/generate_ovpn_client_file.py @@ -19,42 +19,53 @@ import argparse from jinja2 import Template from textwrap import fill -from vyos.configquery import ConfigTreeQuery +from vyos.config import Config from vyos.ifconfig import Section client_config = """ client nobind -remote {{ remote_host }} {{ port }} +remote {{ local_host if local_host else 'x.x.x.x' }} {{ port }} remote-cert-tls server -proto {{ 'tcp-client' if protocol == 'tcp-active' else 'udp' }} -dev {{ device }} -dev-type {{ device }} +proto {{ 'tcp-client' if protocol == 'tcp-passive' else 'udp' }} +dev {{ device_type }} +dev-type {{ device_type }} persist-key persist-tun verb 3 # Encryption options +{# Define the encryption map #} +{% set encryption_map = { + 'des': 'DES-CBC', + '3des': 'DES-EDE3-CBC', + 'bf128': 'BF-CBC', + 'bf256': 'BF-CBC', + 'aes128gcm': 'AES-128-GCM', + 'aes128': 'AES-128-CBC', + 'aes192gcm': 'AES-192-GCM', + 'aes192': 'AES-192-CBC', + 'aes256gcm': 'AES-256-GCM', + 'aes256': 'AES-256-CBC' +} %} + {% if encryption is defined and encryption is not none %} -{% if encryption.cipher is defined and encryption.cipher is not none %} -cipher {{ encryption.cipher }} -{% if encryption.cipher == 'bf128' %} -keysize 128 -{% elif encryption.cipher == 'bf256' %} -keysize 256 +{% if encryption.ncp_ciphers is defined and encryption.ncp_ciphers is not none %} +cipher {% for algo in encryption.ncp_ciphers %} +{{ encryption_map[algo] if algo in encryption_map.keys() else algo }}{% if not loop.last %}:{% endif %} +{% endfor %} + +data-ciphers {% for algo in encryption.ncp_ciphers %} +{{ encryption_map[algo] if algo in encryption_map.keys() else algo }}{% if not loop.last %}:{% endif %} +{% endfor %} {% endif %} -{% endif %} -{% if encryption.ncp_ciphers is defined and encryption.ncp_ciphers is not none %} -data-ciphers {{ encryption.ncp_ciphers }} -{% endif %} {% endif %} {% if hash is defined and hash is not none %} auth {{ hash }} {% endif %} -keysize 256 -comp-lzo {{ '' if use_lzo_compression is defined else 'no' }} +{{ 'comp-lzo' if use_lzo_compression is defined else '' }} -----BEGIN CERTIFICATE----- @@ -79,7 +90,7 @@ comp-lzo {{ '' if use_lzo_compression is defined else 'no' }} """ -config = ConfigTreeQuery() +config = Config() base = ['interfaces', 'openvpn'] if not config.exists(base): @@ -89,10 +100,22 @@ if not config.exists(base): if __name__ == '__main__': parser = argparse.ArgumentParser() -
