Openvpn server config ex le


The command is also passed the pathname of a freshly created temporary file as the last argument (after any arguments specified in cmd ), to be used by the command to pass dynamically generated config file directives back to OpenVPN. The command is passed the common name and IP address of the just-authenticated client as environmental variables (see environmental variable section below).

Conf ainsi que les certificats et clés sont à placer dans ~/Library/openvpn. La dernière version est Tunnelblick_3. Le fichier de configuration se terminant en. Une fois l’interface graphique lancée, il est possible de se connecter ou de regarder en détails les logs. Le client disponible pour Mac OS X est Tunnelblick.

First, make sure the client-side config file enables selective compression by having at least one –comp-lzo directive, such as –comp-lzo no. –comp-noadapt When used in conjunction with –comp-lzo, this option will disable OpenVPN’s adaptive compression algorithm. If the data being sent over the tunnel is already compressed, the compression efficiency will be very low, triggering openvpn to disable compression for a period of time until the next re-sample test. In such cases, one can optimize the event loop by avoiding the poll/epoll/select call, improving CPU efficiency by 5% to 10%. If file does not exist, it will be created. This option is persistent over the entire course of an OpenVPN instantiation and will not be reset by SIGHUP, SIGUSR1, or –ping-restart. Such blocking is unnecessary on some platforms which don’t support write blocking on UDP sockets or TUN/TAP devices. Multiple interfaces, or secondary IP addresses), and is not using –local to force binding to one specific address only. –management-log-cache n Cache the most recent n lines of log file history for usage by the management channel. H for additional information on debug levels). –management-client-group g When the management interface is listening on a unix domain socket, only allow connections from group g. Normally, adaptive compression is enabled with –comp-lzo. –suppress-timestamps Avoid writing timestamps to log messages, even when they otherwise would be prepended. With adaptive compression, OpenVPN will periodically sample the compression process to measure its efficiency. The documentation is in doc and the actual plugin modules are in lib. –fast-io (Experimental) Optimize TUN/TAP/UDP I/O writes by avoiding a call to poll/epoll/select prior to the write operation. Each level shows all info from the previous levels. This directive does not affect the –http-proxy username/password. Pw-file, if specified, is a password file (password on first line) or “stdin” to prompt from standard input. –management IP port [pw-file] Enable a TCP server on IP:port to handle daemon management functions. This option can only be used on non-Windows systems, when –proto udp is specified, and when –shaper is NOT specified. Signal can be set to “SIGHUP” or “SIGTERM”. It is always cached. ] Echo parms to log output. –nice n Change process priority after initialization ( n greater than 0 is lower priority, n less than zero is higher priority). This is useful to limit repetitive logging of similar message types. Mode may be “yes”, “no”, or “adaptive” (default). Multiple plugin modules can be cascaded, and modules can be used in tandem with scripts. Multiple plugin modules may be loaded into one OpenVPN process. See the OpenVPN 1. 1 to 4 — Normal usage range. Note 2: if you do an IPv6+IPv4 dual-stack bind on a Linux machine with multiple IPv4 address, connections to IPv4 addresses will not work right on kernels before 3. If the client connection fails to connect or is disconnected, a SIGTERM signal will be generated causing OpenVPN to quit. –comp-lzo [mode] Use fast LZO compression — may add up to 1 byte per packet for incompressible data. Only query the management channel for inputs which ordinarily would have been queried from the console. Next in a –client-config-dir file, specify the compression setting for the client, for example: comp-lzo yes push “comp-lzo yes” The first line sets the comp-lzo setting for the server side of the link, the second sets the client side. It is strongly recommended that IP be set to 127. –mute n Log at most n consecutive messages in the same category. This option needs to be used when a server has more than one IP address (e. While the management port is designed for programmatic control of OpenVPN by other applications, it is possible to telnet to the port, using a telnet client in “raw” mode. –status-version [n] Choose the status file format version number. This is useful when you wish to disconnect an OpenVPN session on user logoff. To use a unix domain socket, specify the unix socket pathname in place of IP and set port to ‘unix’. –verb n Set output verbosity to n (default=1). –writepid file Write OpenVPN’s main process ID to file. Designed to be used to send messages to a controlling application which is receiving the OpenVPN log output. –management-client-pf Management interface clients must specify a packet filter file for each connecting client. –management-query-proxy Query management channel for proxy server information for a specific –remote (client-only). Tunnel mode will cause the management interface to listen for a TCP connection on the local VPN address of the TUN/TAP interface. –log-append file Append logging messages to file. –management-query-remote Allow management interface to override –remote directives (client-only). This is not supported on all platforms, and it adds more processing, so it’s not enabled by default. For more information and examples on how to build OpenVPN plug-in modules, see the README file in the plugin folder of the OpenVPN source distribution. –management-client Management interface will connect as a TCP/unix domain client to IP:port specified by –management rather than listen as a TCP server or on a unix domain socket. 0 — No output except fatal errors. Adaptive compression tries to optimize the case where you have compression enabled, but you are sending predominantly incompressible (or pre-compressed) packets over the tunnel, such as an FTP or rsync transfer of a large, compressed file. Once connected, type “help” for a list of commands. The password provided will set the password which TCP clients will need to provide in order to access management functions. –management-signal Send SIGUSR1 signal to OpenVPN if management session disconnects. 15, due to missing kernel support for the IPv4-mapped case (some distributions have ported this to earlier kernel versions, though). –status file [n] Write operational status to file every n seconds. 6 to 11 — Debug info range (see errlevel. –plugin module-pathname [init-string] Load plug-in module from the file module-pathname, passing init-string as an argument to the module initialization function. 5 — Output R and W characters to the console for each packet read and write, uppercase is used for TCP/UDP packets and lowercase is used for TUN/TAP packets. In particular, this applies to log messages sent to stdout. Note that on Windows, when OpenVPN is started as a service, logging occurs by default without the need to specify this option. –management-client-auth Gives management interface client the responsibility to authenticate clients after their client certificate has been verified. –management-client-user u When the management interface is listening on a unix domain socket, only allow connections from user u. –management-forget-disconnect Make OpenVPN forget passwords when management session disconnects. Level 3 is recommended if you want a good summary of what’s happening without being swamped by output. If the return code of the module/script controls an authentication function (such as tls-verify, auth-user-pass-verify, or client-connect), then every module and script must return success (0) in order for the connection to be authenticated. –remap-usr1 signal Control whether internally or externally generated SIGUSR1 signals are remapped to SIGHUP (restart without persisting state) or SIGTERM (exit). If file already exists it will be truncated. X HOWTO for an example on using OpenVPN with xinetd: http://openvpn. Txt in OpenVPN distribution for detailed notes. In a server mode setup, it is possible to selectively turn compression on or off for individual clients. Txt file in the management folder of the OpenVPN source distribution. Status can also be written to the syslog by sending a SIGUSR2 signal. If you are using an RPM install of OpenVPN, see /usr/share/openvpn/plugin. Also note that in wait mode, each OpenVPN tunnel requires a separate TCP/UDP port and a separate inetd or xinetd entry. Currently n can be 1, 2, or 3 and defaults to 1. The modules will be called by OpenVPN in the order that they are declared in the config file. This option behaves exactly like –log except that it appends to rather than truncating the log file. The management interface provides a special mode where the TCP management link can operate over the tunnel itself. –management-hold Start OpenVPN in a hibernating state, until a client of the management interface explicitly starts it with the hold release command. If both a plugin and script are configured for the same callback, the script will be called last. For –management-client this option is not needed since a disconnect will always generate a SIGTERM. This option will add some extra lookups to the packet path to ensure that the UDP reply packets are always sent from the address that the client is talking to. –multihome Configure a multi-homed UDP server. To enable this mode, set IP = “tunnel”. Html –log file Output logging messages to file, including output to stdout/stderr which is generated by called scripts. The management interface can also listen on a unix domain socket, for those platforms that support it. By default, no remapping occurs. 1 (localhost) to restrict accessibility of the management server to local clients. Note: this option is only relevant for UDP servers. For detailed documentation on the management interface, see the management-notes. This will turn off compression by default, but allow a future directive push from the server to dynamically change the on/off/adaptive setting. While the default behavior is to create a unix domain socket that may be connected to by any process, the –management-client-user and –management-client-group directives can be used to restrict access. –management-query-passwords Query management channel for private key password and –auth-user-pass username/password. The purpose of such a call would normally be to block until the device or socket is ready to accept the write. This option takes effect immediately when it is parsed in the command line and will supercede syslog output if –daemon or –inetd is also specified. –management-external-key Allows usage for external private key file instead of –key option (client-only). Txt in OpenVPN distribution for detailed notes. –management-up-down Report tunnel up/down events to management interface.

The following standalone example shows how the –up script can be called in both an initialization and restart context. (NOTE: for security reasons, don’t run the following example unless UDP port 9999 is blocked by your firewall. Also, the example will run indefinitely, so you should abort with control-c).

Once in OpenVPN, the –iroute directive routes to the specific client. Remember that you must also add the route to the system routing table as well (such as by using the –route directive). This directive can be used to route a fixed subnet from the server to a particular client, regardless of where the client is connecting from. The reason why two routes are needed is that the –route directive routes the packet from the kernel to OpenVPN.

–management-client-user u When the management interface is listening on a unix domain socket, only allow connections from user u. Normally, adaptive compression is enabled with –comp-lzo. If the client connection fails to connect or is disconnected, a SIGTERM signal will be generated causing OpenVPN to quit. Tunnel mode will cause the management interface to listen for a TCP connection on the local VPN address of the TUN/TAP interface. –mute n Log at most n consecutive messages in the same category. Txt file in the management folder of the OpenVPN source distribution. –management IP port [pw-file] Enable a TCP server on IP:port to handle daemon management functions.

Next in a –client-config-dir file, specify the compression setting for the client, for example: comp-lzo yes push “comp-lzo yes” The first line sets the comp-lzo setting for the server side of the link, the second sets the client side. Txt in OpenVPN distribution for detailed notes.

–service exit-event [0|1] Should be used when OpenVPN is being automatically executed by another program in such a context that no interaction with the user via display or keyboard is possible. On non-Windows systems, the ifconfig(8) command provides similar functionality. This is known to kick Windows into recognizing pushed DNS servers. –dhcp-release Ask Windows to release the TAP adapter lease on shutdown. This option is intended to be used to troubleshoot problems with the –ifconfig and –ip-win32 options, and is used to give the TAP-Win32 adapter time to come up before Windows IP Helper API operations are applied to it. –show-valid-subnets (Standalone) Show valid subnets for –dev tun emulation. When executing an OpenVPN process using the –service directive, OpenVPN will probably not have a console window to output status/error messages, therefore it is useful to use –log or –log-append to write these messages to a file. Multiple OpenVPN processes can be simultaneously executed with the same exit-event parameter. –pause-exit Put up a “press any key to continue” message on the console prior to OpenVPN program exit. –show-net-up Output OpenVPN’s view of the system routing table and network adapter list to the syslog or log file after the TUN/TAP adapter has been brought up and any routes have been added. This option has the same caveats as –dhcp-renew above. This directive can only be used by an administrator. –register-dns Run net stop dnscache, net start dnscache, ipconfig /flushdns and ipconfig /registerdns on connection initiation. Exit-event is the name of a Windows global event object, and OpenVPN will continuously monitor the state of this event object and exit when it becomes signaled. Since the TAP-Win32 driver exports an ethernet interface to Windows, and since TUN devices are point-to-point in nature, it is necessary for the TAP-Win32 driver to impose certain constraints on TUN endpoint address selection. –show-adapters (Standalone) Show available TAP-Win32 adapters which can be selected using the –dev-node option. Namely, the point-to-point endpoints used in TUN device emulation must be the middle two addresses of a /30 subnet (netmask 255. This option is automatically used by the Windows explorer when OpenVPN is run on a configuration file using the right-click explorer menu. –show-net (Standalone) Show OpenVPN’s view of the system routing table and network adapter list. The second parameter indicates the initial state of exit-event and normally defaults to 0. If TAP-adapter is omitted, all TAP adapters on the system will be configured to allow non-admin access. In any case, the controlling process can signal exit-event, causing all such OpenVPN processes to exit. It uses Windows Filtering Platform (WFP) and works on Windows Vista or later. You may want to use –setenv opt or –ignore-unknown-option (not suitable for Windows XP) to ignore said error. –block-outside-dns Block DNS servers on other network adapters to prevent DNS leaks. –allow-nonadmin [TAP-adapter] (Standalone) Set TAP-adapter to allow access from non-administrative accounts. The non-admin access setting will only persist for the length of time that the TAP-Win32 device object and driver remain loaded, and will need to be re-enabled after a reboot, or if the driver is unloaded and reloaded. In general, end-users should never need to explicitly use this option, as it is automatically added by the OpenVPN service wrapper when a given OpenVPN configuration is being run as a service. Note that pushing unknown options from server does not trigger fatal errors. –dhcp-renew Ask Windows to renew the TAP adapter lease on startup. This option is considered unknown on non-Windows platforms and unsupported on Windows XP, resulting in fatal error. This option prevents any application from accessing TCP or UDP port 53 except one inside the tunnel. This option is normally unnecessary, as Windows automatically triggers a DHCP renegotiation on the TAP adapter when it comes up, however if you set the TAP-Win32 adapter Media Status property to “Always Connected”, you may need this flag.

This is not needed for executable files, such as. For example, if you have a Visual Basic script, you must use this syntax now:. To run scripts in Windows in earlier OpenVPN versions you needed to either add a full path to the script interpreter which can parse the script or use the system flag to run these scripts. 3 it is now a strict requirement to have full path to the script interpreter when running non-executables files. As of OpenVPN v2.
