인터넷을 통해 SSH를 통해 Ubuntu 서버에 연결

SSH를 통해 로컬로 액세스할 수 있는 우분투 서버가 있지만 SSH를 통해 인터넷에서 액세스할 수 있도록 구성해야 합니다. eth1을 인터넷에 연결하고 인터페이스 파일을 구성했습니다. 저는 VPN의 개념을 이해하려고 노력 중이었고 여러 튜토리얼을 따랐지만 그 중 어느 것도 효과가 없었습니다. 먼저 OpenVPN을 사용해 보았습니다.https://help.ubuntu.com/12.04/serverguide/openvpn.html, Ubuntu 및 Windows의 OpenVPN 클라이언트에 설치 및 구성하고 구성 파일과 키를 복사했지만 연결하려고 하면 연결 시간 초과가 발생합니다. 이것은 Windows openvpn 클라이언트에 복사한 구성 파일(client.ovpn)입니다.

# Sample client-side OpenVPN 2.0 config file #
# for connecting to multi-client server.     #
#                                            #
# This configuration can be used by multiple #
# clients, however each client should have   #
# its own cert and key files.                #
#                                            #
# On Windows, you might want to rename this  #
# file so it has a .ovpn extension           #

# Specify that we are a client and that we
# will be pulling certain config file directives
# from the server.
client

# Use the same setting as you are using on
# the server.
# On most systems, the VPN will not function
# unless you partially or fully disable
# the firewall for the TUN/TAP interface.
;dev tap
dev tun

# Windows needs the TAP-Win32 adapter name
# from the Network Connections panel
# if you have more than one.  On XP SP2,
# you may need to disable the firewall
# for the TAP adapter.
;dev-node MyTap

# Are we connecting to a TCP or
# UDP server?  Use the same setting as
# on the server.
;proto tcp
proto udp

# The hostname/IP and port of the server.
# You can have multiple remote entries
# to load balance between the servers.
remote my-server-1 1194
;remote my-server-2 1194

# Choose a random host from the remote
# list for load-balancing.  Otherwise
# try hosts in the order specified.
;remote-random

# Keep trying indefinitely to resolve the
# host name of the OpenVPN server.  Very useful
# on machines which are not permanently connected
# to the internet such as laptops.
resolv-retry infinite

# Most clients don't need to bind to
# a specific local port number.
nobind

# Downgrade privileges after initialization (non-Windows only)
;user nobody
;group nogroup

# Try to preserve some state across restarts.
persist-key
persist-tun

# If you are connecting through an
# HTTP proxy to reach the actual OpenVPN
# server, put the proxy server/IP and
# port number here.  See the man page
# if your proxy server requires
# authentication.
;http-proxy-retry # retry on connection failures
;http-proxy [proxy server] [proxy port #]

# Wireless networks often produce a lot
# of duplicate packets.  Set this flag
# to silence duplicate packet warnings.
;mute-replay-warnings

# SSL/TLS parms.
# See the server config file for more
# description.  It's best to use
# a separate .crt/.key file pair
# for each client.  A single ca
# file can be used for all clients.
ca ca.crt
cert client1.crt
key client1.key

# Verify server certificate by checking
# that the certicate has the nsCertType
# field set to "server".  This is an
# important precaution to protect against
# a potential attack discussed here:
#  http://openvpn.net/howto.html#mitm

# To use this feature, you will need to generate
# your server certificates with the nsCertType
# field set to "server".  The build-key-server
# script in the easy-rsa folder will do this.
ns-cert-type server

# If a tls-auth key is used on the server
# then every client must also have the key.
;tls-auth ta.key 1

# Select a cryptographic cipher.
# If the cipher option is used on the server
# then you must also specify it here.
;cipher x

# Enable compression on the VPN link.
# Don't enable this unless it is also
# enabled in the server config file.

# Set log file verbosity.

# Silence repeating messages

제대로 하고 있는지도 모르겠고, Ubuntu 서버의 ifconfig tun0의 inet 주소인 (10.8.0.1)에 연결하는 데 어떤 서버 주소를 사용하고 있는지 잘 모르겠습니다.

나는 또한 이것을 시도했습니다 :https://wiki.ubuntu.com/VPN라우터의 게이트웨이를 사용했지만 NT 도메인이 무엇인지, SSH를 통해 연결하는 방법을 모르겠습니다.
