【求助】OpenVPN的log文件中測試路由

【求助】OpenVPN的log文件中測試路由

OpenVPN成功連接后，在log文件的最後端會顯示如下信息。

Thu Dec 17 20:00:27 2009 us=413948 TEST ROUTES: 0/0 succeeded len=-1 ret=0 a=0 u/d=down
Thu Dec 17 20:00:27 2009 us=413974 Route: Waiting for TUN/TAP interface to come up...
Thu Dec 17 20:00:28 2009 us=572471 TEST ROUTES: 0/0 succeeded len=-1 ret=0 a=0 u/d=down
Thu Dec 17 20:00:28 2009 us=572498 Route: Waiting for TUN/TAP interface to come up...
Thu Dec 17 20:00:29 2009 us=730744 TEST ROUTES: 0/0 succeeded len=-1 ret=0 a=0 u/d=down

Thu Dec 17 20:00:32 2009 us=47223 Route: Waiting for TUN/TAP interface to come up...
Thu Dec 17 20:00:33 2009 us=205820 TEST ROUTES: 0/0 succeeded len=-1 ret=0 a=0 u/d=down
Thu Dec 17 20:00:33 2009 us=205838 Route: Waiting for TUN/TAP interface to come up...
Thu Dec 17 20:00:34 2009 us=231252 TEST ROUTES: 0/0 succeeded len=-1 ret=1 a=0 u/d=up
Thu Dec 17 20:00:34 2009 us=231271 Initialization Sequence Completed

為什麼在連接的過程中，會不斷的測試路由呢？最後的參數，len，ret，a，u/d又分別代表什麼呢？

配置文件附上

從日誌上看是路由信息在變化

##############################################
# 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 192.168.201.2 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 nobody

# 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

# 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 client26.crt
key client26.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.
comp-lzo

;log-append OpenVPN.log

# Set log file verbosity.
verb 4

# Silence repeating messages
;mute 20


配置文件如上，log文件等級選擇的是4，就是不太明白，測試路由的時候為什麼要測試好幾次。

在伺服器配置中是否分配客戶端的路由信息

等待TAP工作正常吧。。。。。
