[Resolved] client-config-dir ccd

Post by corsairetc » Wed Nov 20, 2013 9:45 am

Hello,
I try to testing the client-config-dir ccd and setup it via this howto
I want to provide network 192.168.2.0/24 behind my client but I still get some errors in log.
Here is the error log list:

    # open up this port on your firewall.

    # TCP or UDP server?
    ;proto tcp

    # "dev tun" will create a routed IP tunnel,
    # "dev tap" will create an ethernet tunnel.
    # Use "dev tap0" if you are ethernet bridging
    # and have precreated a tap0 virtual interface
    # and bridged it with your ethernet interface.
    # If you want to control access policies
    # over the VPN, you must create firewall
    # rules for the the TUN/TAP interface.
    # On non-Windows systems, you can give
    # an explicit unit number, such as tun0.
    # On Windows, use "dev-node" for this.

    # (cert), and private key (key). Each client

    #
    # See the "easy-rsa" directory for a series
    # of scripts for generating RSA certificates
    # and private keys. Remember to use
    # a unique Common Name for the server
    # and each of the client certificates.

    # Configure server mode for ethernet bridging.
    # You must first use your OS's bridging capability
    # to bridge the TAP interface with the ethernet
    # NIC interface. Then you must manually set the
    # IP/netmask on the bridge interface, here we
    # assume 10.8.0.4/255.255.255.0. Finally we
    # must set aside an IP range in this subnet
    # (start=10.8.0.50 end=10.8.0.100) to allocate
    # to connecting clients. Leave this line commented
    # out unless you are ethernet bridging.
    ;server-bridge 10.8.0.4 255.255.255.0 10.8.0.50 10.8.0.100

    # Push routes to the client to allow it
    # to reach other private subnets behind
    # the server. Remember that these
    # private subnets will also need
    # to know to route the OpenVPN client
    # address pool (10.8.0.0/255.255.255.0)
    # back to the OpenVPN server.
    push "route 192.168.5.0 255.255.255.0"
    push "route 192.168.3.0 255.255.255.0"

    # To assign specific IP addresses to specific
    # clients or if a connecting client has a private
    # subnet behind it that should also have VPN access,
    # use the subdirectory "ccd" for client-specific
    # configuration files (see man page for more info).

    # EXAMPLE: Suppose the client
    # having the certificate common name "Thelonious"
    # also has a small subnet behind his connecting
    # machine, such as 192.168.40.128/255.255.255.248.
    # First, uncomment out these lines:
    client-config-dir ccd
    route 192.168.2.0 255.255.255.0

    # Then create a file ccd/Thelonious with this line:
    # iroute 192.168.40.128 255.255.255.248
    # This will allow Thelonious' private subnet to
    # access the VPN. This example will only work
    # if you are routing, not bridging, i.e. you are
    # using "dev tun" and "server" directives.

    # EXAMPLE: Suppose you want to give
    # Thelonious a fixed VPN IP address of 10.9.0.1.
    # First uncomment out these lines:
    ;client-config-dir ccd
    ;route 10.9.0.0 255.255.255.252
    # Then add this line to ccd/Thelonious:
    # ifconfig-push 10.9.0.1 10.9.0.2

    # Suppose that you want to enable different
    # firewall access policies for different groups
    # of clients. There are two methods:
    # (1) Run multiple OpenVPN daemons, one for each
    # group, and firewall the TUN/TAP interface
    # for each group/daemon appropriately.
    # (2) (Advanced) Create a script to dynamically
    # modify the firewall in response to access
    # from different clients. See man
    # page for more info on learn-address script.
    ;learn-address ./script

    # If enabled, this directive will configure
    # all clients to redirect their default
    # network gateway through the VPN, causing
    # all IP traffic such as web browsing and
    # and DNS lookups to go through the VPN
    # (The OpenVPN server machine may need to NAT
    # the TUN/TAP interface to the internet in
    # order for this to work properly).
    # CAVEAT: May break client's network config if
    # client's local DHCP server packets get routed
    # through the tunnel. Solution: make sure
    # client's local DHCP server is reachable via
    # a more specific route than the default route
    # of 0.0.0.0/0.0.0.0.
    ;push "redirect-gateway"

    # Certain Windows-specific network settings
    # can be pushed to clients, such as DNS
    # or WINS server addresses. CAVEAT:
    # http://openvpn.net/faq.html#dhcpcaveats
    ;push "dhcp-option DNS 10.8.0.1"
    ;push "dhcp-option WINS 10.8.0.1"

    # Uncomment this directive to allow different
    # clients to be able to "see" each other.
    # By default, clients will only see the server.
    # To force clients to only see the server, you
    # will also need to appropriately firewall the
    # server's TUN/TAP interface.
    client-to-client

    # Uncomment this directive if multiple clients
    # might connect with the same certificate/key
    # files or common names. This is recommended
    # only for testing purposes. For production use,
    # each client should have its own certificate/key
    # pair.
    #
    # IF YOU HAVE NOT GENERATED INDIVIDUAL
    # CERTIFICATE/KEY PAIRS FOR EACH CLIENT,
    # EACH HAVING ITS OWN UNIQUE "COMMON NAME",
    # UNCOMMENT THIS LINE OUT.
    ;duplicate-cn

    # The keepalive directive causes ping-like
    # messages to be sent back and forth over
    # the link so that each side knows when
    # the other side has gone down.
    # Ping every 10 seconds, assume that remote
    # peer is down if no ping received during
    # a 120 second time period.

Yes you right, sorry it is stupid mystake :oops: , and I also found duplicity with route 192.168.2.0 it was here there twice. Now is start log without errors.
Now I have to test if client network PC in lan 192.168.2.0 see to server network.
