|---|---|
| -- | OpenVPN allows any option to be placed either on the command line or in a configuration file. Though all command line options are preceded by a double-leading-dash ("--"), this prefix must be removed when an option is placed in a configuration file. |
| /30 | #1: Default behaviour assigns a /30 subnet(4 addresses) to each peer. See http://goo.gl/6vemm for background #2: you can avoid this behavior by reading !topology #3: by default, first client is .6, then .10 .14 .18 etc #4: use openvpn --show-valid-subnets to see the subnets you can use in net30 #5: <+EugeneKay> tl;dr: Windows sucks, use --topology subnet in your server.conf. |
| 2.1-winpass-script | http://article.gmane.org/gmane.network.openvpn.user/24575 |

| ad | see !activedirectory |
| all | #1: please pastebin your client and server configs (with comments removed, you can use `grep -vE '^#' client.conf`), also include which OS and version of openvpn, include your routing tables, firewall settings and client/server logfiles #2: For more detailed instructions, look to: !logs !configs !interface |
| allinfo | Please type !configs !logs and !interface to see all the info we want to be able to help you |
| android | #1: CyanogenMod includes an integrated OpenVPN client. You will need a !p12 to load your certificates. #2: If you can't get CM, get root/busybox/tun and grab android-openvpn-installer + openvpn-settings from Market #3: if you have ICS, you no longer need root, use the oficial android package at http://swupdate.openvpn.net/beta-downloads/OpenVPN-RC1.apk You will need in-line ca |
| ask | #1: don't ask to ask, just ask your question please #2: http://www.latinsud.com/answer/ #3: http://www.catb.org/~esr/faqs/smart-questions.html to learn how to get help |
| authpass | #1: please see --auth-user-pass-verify in the manual to learn how to force clients to use passwords in addition to certs #2: or to ONLY use passwords (no certs, highly NOT recommended) also use --client-cert-not-required #3: and if you want the login name to be used as the common-name for things like ccd entries, use --username-as-common-name |
| badtime | if !certverify shows you error 9 at 1 depth lookup:certificate is not yet valid. You need to check the times/dates/years/timezones on the machines, including the CA |
| basic | if you do not understand basic networking, you probably should not be administrating a vpn... you should understand the basics of routing / firewalls first |
| bcast | #1: pptp source tree has bcrelay in it, bcrelay can be used to relay broadcasts over a tun setup #2: http://www.hanksoft.de/service/46-udpbroadcastforwarder seems to be a windows program for relaying bcast (use google translate if needed) |

| blog | Do not follow blog posts for openvpn. They are wrong, they are old, they are written by fools. We won't read them, or troubleshoot them. |
| bonjour | http://www.dslreports.com/forum/r18525512-Routing-Bonjour-How-to |
| book | http://www.packtpub.com/openvpn-2-cookbook/book check out JJK's awesome cookbook for openvpn 2! |
| bot | I'm a bot.. just a bot. krzee and ecrist are my maintainers, and I haven't said anything, if you'd notice, the person who spoke just before me gave a !command to make me speak :P |
| both | If you do not control both ends of the link (server and client) then there is not much we can do to help you. Please talk to your network admin instead. |
| bridge | #1: http://openvpn.net/index.php/documentation/miscellaneous/ethernet-bridging.html for the doc #2: http://openvpn.net/index.php/documentation/faq.html#bridge1 for info from the FAQ #3: also see !tunortap and !layer2 and read --server-bridge in the manual (!man) |
| bridge-dhcp | http://openvpn.net/faq.html#bridge-addressing for making clients grab dhcp ip over the bridge but not over-riding dhcp ip from local dhcp server |
| bridge-fw | "ebtables" is Linux uses ebtables for firewalling layer 2 bridges. See http://ebtables.sourceforge.net/br_fw_ia/br_fw_ia.html and http://ebtables.sourceforge.net/br_fw_ia/PacketFlow.png to understand how layer 2 and layer 3 works in linux and how to use ebtables |
| bridging | Using bridges is either completely stupid or clever. It is stupid if you do it because you think it is easier. It is clever if you're a network knowledgeable person who understands networking very well and knows why routing won't fit for you |
| broadcast-relay | a software that comes with pptp. use it in tun mode when needing broadcasts, and WINS isnt enough. |
| bsdnat | see !fbsdnat |
| buffer | when you see write UDPv4: No buffer space available (code=55) you probably have a routing loop. the way to fix this is to get a book on basic networking, preferably a coloring book! |
| bugs | https://community.openvpn.net/openvpn if we tell you that you found a bug. go there, open an account, and file a bug report in trac (your forum login is good for the trac too) |
| c2c | "client-to-client" is with this option packets from 1 client to another are routed inside the server process. without it packets leave the server process, hit the kernel (firewall, routing table) and if allowed by firewall and routed back to server process, they go to the client. you use this option when you do not want to use selective firewall rules on what clients can access things behind other clients |
| ccd | #1: entries that are basically included into server.conf, but only for the specified client based on common-name. use --client-config-dir <dir> to enable it, then put the config options for the client in <dir>/common-name #2: the ccd file is parsed each time the client connects. |
| centos | See !epel5 |
| cert_chains | https://community.openvpn.net/openvpn/wiki/Using_Certificate_Chains ... JJK actually mentions that scenario in this page |
| certinfo | run `openssl x509 -in <file> -noout -text` for info from your cert file |
| certs | #1: use !easy-rsa-unix for easy-rsa #2: use !ssl-admin for ecrists copy of ssl-admin to make and manage your certs |
| certverify | #1: verify your certs are signed correctly by running `openssl verify -CAfile <ca.crt> <client.crt>` for client.crt and server.crt #2: also make sure you use the same ca.crt on both sides by checking their md5 |

| cidr | http://www.oav.net/mirrors/cidr.html |
| cisco | #1: An open-source client for Cisco SSL VPN is available from http://www.infradead.org/openconnect.html #2: OpenConnect is availabe in FreeBSD ports in security/openconnect |
| client-connect | --client-connect <script>, runs script on client connection. This can be useful for generating firewall rules dynamicly, or for assigning static ips. This can do anything that a ccd (see !ccd) entry can do, but dynamicly... to use it that way, you should write your dynamic ccd commands to the file named by $1. |
| client-to-client | with this option packets from 1 client to another are routed inside the server process. without it packets leave the server process, hit the kernel (firewall, routing table) and if allowed by firewall and routed back to server process, they go to the client. you use this option when you do not want to use selective firewall rules on what clients can access things behind other clients |
| clientlan | #1: for a lan behind a client, the client must have ip forwarding enabled (!ipforward), the server needs a route to the lan, the server needs to push a route for the lan to clients, the server needs a ccd (!ccd) file for the client with an iroute (!iroute) entry in it, and the router of the lan the client is on needs a route added to it (!route_outside_openvpn) #2: see !route for a better explanation |
| comment | you can use ; or # to make comments in the config file |
| comp | if you see Bad LZO decompression header you have a mis-match in your comp-lzo settings. You need to be sure you have the same setting in all configs for comp-lzo, or that you dont have it in any configs. |
| confgen | #1: http://www.doeshosting.com/code/openvpn-confgen.tgz for the bash config generator #2: you can use svn co http://www.secure-computing.net/svn/trunk/openvpn-confgen/ #3: you must run this in bash |
| configs | #1: please pastebin your client and server configs (with comments removed, you can use `grep -vE '^#|^;|^$' server.conf`), also include which OS and version of openvpn. #2: dont forget to include any ccd entries |
| control | http://secure-computing.net/files/control.jpg |
| crl | #1: --crl-verify <crl> A CRL (certificate revocation list) is used when a particular key is compromised but when the overall PKI is still intact. The only time when it would be necessary to rebuild the entire PKI from scratch would be if the root certificate key itself was compromised. #2: you can make use of CRL by using the revoke-full script in easy-rsa (packaged with openvpn) that will create the CRL file for you. ssl-admin will also build a crl for you |
| current | #1: Our policy is to only support current versions of software. If your Linux distribution's repository doesn't have the latest, you'll need to compile from source. See /topic for the latest versions of OpenVPN software (usually at the beginning). Anything earlier than these, and you'll be REQUIRED to upgrade before we offer assistance. #2: The current version of OpenVPN can be downloaded from http://openvpn.net/index.php/open-source/downloads.html for RELEASE and BETA versions, and a tarball snapshot of the development tree can be had from ftp://ftp.secure-computing.net/pub/openvpn/ |
| dazo | "eurephia" is http://www.eurephia.net/ |
| debian | Although we are aware the Debian stable package repository has OpenVPN 2.1rc11, to offer support, we require users to run the current version of OpenVPN. See !download for information on where/how to obtain a recent release. |
| def1 | #1: used in redirect-gateway, Add the def1 flag to override the default gateway by using 0.0.0.0/1 and 128.0.0.0/1 rather than 0.0.0.0/0. This has the benefit of overriding but not wiping out the original default gateway. #2: please see --redirect-gateway in the man page ( !man ) to fully understand #3: push "redirect-gateway def1" |
| dev | https://lists.sourceforge.net/lists/listinfo/openvpn-devel to sign up for devel mail list |
| dh | build-dh from easy-rsa and option dh in ssl-admin, creates a file which is a prime number the size of bits you defined (1024 default) which is used in the diffie-hellman algorithm to provide a method to negotiate a secure connection over an insecure channel. just one of the layers of encryption available to you in your VPN |
| dhcp | redirect-gateway bypass-dhcp gets around the problem of DHCP packets to the local DHCP server being incorrectly routed into the tunnel. Available in 2.1 |

| gvpe | http://software.schmorp.de/pkg/gvpe.html <Bushmills> Unlike other virtual private network" solutions which merely create a single tunnel, GVPE creates a real network with multiple endpoints. free, opensource, for nixes, meant for those looking for a vpn with direct peer connections. those who'd be sent to hamachi otherwise. |
| help | My owner did not give me a help command |
| hmac | #1: The tls-auth directive adds an additional HMAC signature to all SSL/TLS handshake packets for integrity verification. Any UDP packet not bearing the correct HMAC signature can be dropped without further processing. The tls-auth HMAC signature provides an additional level of security above and beyond that provided by SSL/TLS. #2: openvpn --genkey --secret ta.key to make the tls static key , in configs: tls-auth ta.key # , 1 for client or 0 for server in the configs |
| howsecurityworks | security can be obtained by: something you have (certificates, usb tokens), something you know (passwords), something you are (biometrics). for best security use more than 1. if you save passwords to a file (!pwfile), you change them from something you know to something you have, which destroys the point of using passwords |

| ifconfig | usage: ifconfig l rn | Set TUN/TAP adapter parameters. l is the IP address of the local VPN endpoint. For TUN devices, rn is the IP address of the remote VPN endpoint. For TAP devices, rn is the subnet mask of the virtual ethernet segment which is being created or connected to. |
| insanity | doing the same thing over and over expecting different results |
| interface | #1: paste interface configuration from both client and server, while being disconnected and when beeing connected. Be sure to also add the routing tables for both situations from client and from server #2: in windows: ipconfig /all - unix: ifconfig -a , and for routing tables: netstat -rn |

| iporder | #1: OpenVPN's internal client IP address selection algorithm works as follows: 1 -- Use --client-connect script generated file for static IP (first choice). #2: Use --client-config-dir file for static IP (next choice) !static for more info #3: Use --ifconfig-pool allocation for dynamic IP (last choice) #4: if you use --ifconfig-pool-persist see !ipp |
| ipp | #1: the option --ifconfig-pool-persist ipp.txt does NOT create static ips #2: Note that the entries in this file are treated by OpenVPN as suggestions only, based on past associations between a common name and IP address. They do not guarantee that the given common name will always receive the given IP address. If you want guaranteed assignment, see !iporder and !static |
| iptables | #1: to test if iptables is your problem, disable all rules or put the defaults to accept: iptables -P INPUT ACCEPT; iptables -P OUTPUT ACCEPT; iptables -P FORWARD ACCEPT; iptables -F; iptables -Z #2: please see http://openvpn.net/man#lbBD for more info #3: you can see http://www.secure-computing.net/wiki/index.php/OpenVPN/Firewall for pf or iptables #4: These is just the basics to get OpenVPN working. Proper firewall design is beyond the scope of this channel. You can try #iptables |

| iroute | does not bypass or alter the kernel's routing table, it allows openvpn to know it should handle the routing when the kernel points to it but the network is not one that openvpn knows about. This is only needed when connecting a LAN which is behind a client, and therefor belongs in a ccd entry. Also see !route and !ccd |
| keepalive | #1: see --keepalive in the manual for how to make clients retry connecting if they get disconnected. #2: basically it is a wrapper for managing --ping and --ping-restart in server/client mode #3: if you use this, don't use --tls-exit and also avoid --single-session and --inactive |

| layer2 | #1: you are using tap, what specific layer2 protocol do you need to work over the vpn? #2: Bridging looks like a good choice to people who don't know how to set up IP routing, but to learn routing is generally far better #3: protocols that use layer2 communicate by MAC address, not IP address |

| nobind | Do not bind to local address and port. The IP stack will allocate a dynamic port for returning packets. Since the value of the dynamic port could not be known in advance by a peer, this option is only suitable for peers which will be initiating connections by using the --remote option. |
| nocert | #1: to use login and pass (NO CERTS) for auth in server setup, you want --username-as-common-name --auth-user-pass-verify --client-cert-not-required #2: to know more, read about those config options in the manual (!man) |

The server, client, and ca certs are all signed by the same ca.key. The server and client use the ca.crt to check that eachother were signed by the right ca.key. Optionally, the client also checks that the server cert was signed specially as a server (see !servercert) |

| port-share | When run in TCP server mode, share the OpenVPN port with another application, such as an HTTPS server. If OpenVPN senses a connection to its port which is using a non-OpenVPN protocol, it will proxy the connection to the server at host:port. Currently only designed to work with HTTP/HTTPS, though it would be theoretically possible to extend to other protocols such as ssh. Not implemented on Windows. |
| pptp | #1: PPTP is known to be a faulty protocol. The designers of the protocol, Microsoft, recommend not to use it due to the inherent risks. Lots of people use PPTP anyway due to ease of use, but that doesn't mean it is any less hazardous. The maintainers of PPTP Client and Poptop recommend using OpenVPN (SSL based) or IPSec instead. http://pptpclient.sourceforge.net/protocol-security.phtml to read about why to not use pptp #2: Why not to use pptp: http://en.wikipedia.org/wiki/Pptp#Security_of_the_PPTP_protocol |
| privledges | just choose a sandbox user/group that nothing else is using, then in config use: user vpnuser and group vpngroup , and if it is the server add: persist-key and persist-tun |

| push | usage: push <command> , goes in the server config and makes the command act as if it was in the client config, can be used in ccd entries |
| push-reset | Don't inherit the global push list for a specific client instance. Specify this option in a client-specific context such as with a --client-config-dir configuration file. This option will ignore --push options at the global config file level. |
| pushdns | #1: push "dhcp-option DNS a.b.c.d" to push dns to the client #2: http://thread.gmane.org/gmane.network.openvpn.user/25139/focus=25147 see that mail archive for some info on pushing dns #3: http://article.gmane.org/gmane.network.openvpn.user/25149 for a perm fix via regedit #4: in unix you'll use the update-resolv-conf script #5: also http://comments.gmane.org/gmane.network.openvpn.user/31975 reports --register-dns as fixing their problems pushing DNS to windows 7 |
| pwfile | #1: OpenVPN will only read passwords from a file if it has been built with the --enable-password-save configure option, or on Windows by defining ENABLE_PASSWORD_SAVE in config-win32.h #2: see --auth-user-pass in the manual (!man) for more info #3: if you're using this with the windows service, you will need --askpass |

| read | <krzee> ive been known to overreact when people look for 2 minutes and ask me to explain it to them |
| redirect | #1: to make all inet traffic flow through the vpn, you will need --redirect-gateway (see !def1), as well as IP forwarding (see !ipforward) and NAT (see !nat) enabled on the server. #2: you may need to use a different dns server when redirecting gateway, see !dns or !pushdns |
| redirect_ips | #1: https://forums.openvpn.net/topic8559.html for more info on giving users their own internet routable IPs #2: it is also possible to directly hand out the ips from --server, jjk explains how to do this in his book (!book) which krzee highly recommends reading |
| release-notes | http://openvpn.net/index.php/open-source/documentation/release-notes.html |

| route_outside_openvpn | #1: If your server is not the default gateway for the LAN, you will need to add routes to your gateway. See ROUTES TO ADD OUTSIDE OPENVPN in !route #2: Here are 2 diagrams that explain how this works: http://www.secure-computing.net/wiki/index.php/Graph http://i.imgur.com/BM9r1.png |
| route_outside_ovpn | "route_outside_openvpn" is (#1) If your server is not the default gateway for the LAN, you will need to add routes to your gateway. See ROUTES TO ADD OUTSIDE OPENVPN in !route or (#2) Here are 2 diagrams that explain how this works: http://www.secure-computing.net/wiki/index.php/Graph http://i.imgur.com/BM9r1.png |
| route_override | #1: https://forums.openvpn.net/viewtopic.php?f=15&t=7161 for how to override --redirect-gateway for a certain subnet #2: to see how to make it so the client will still reply to requests to its public ip over the internet and not the vpn see !splitroute |
| routebyapp | if you want to send only certain apps over the VPN you need to run a socks server on the internal VPN subnet (see !sockd) then get an app like proxifier (google it) to selectively route traffic over the socks proxy based on port/app/subnet or any combination. |

| samesubnet | clients can not connect to a server pushing its lan if on the same subnet. you can only reach your subnet on layer2 or through your gateway, when you create a route for it you will try to reach your gateway over the vpn which dies because you cant reach your gateway |
| sample | #1: http://www.ircpimps.org/openvpn.configs for a working sample config #2: DO NOT use these configs until you understand the commands in them, read up on each first column of the configs in the manpage (see !man) #3: these configs are for a basic multi-user vpn, which you can then build upon to add lans or internet redirecting |
| say | NO! you're not the boss of me! |
| scale | #1: OpenVPN has no hard limits built in, but it is not recommended to run much more than 100 clients per process. #2: Also remember that it is single-threaded, so your throughput will be limited by the speed your CPU can do the crypto. #3: Both of these issues can be handled by running multiple server instances(on several IPs or ports) and having clients round-robin between them |

| static-key | when you use --secret, you are using a static key. this is only valid for point-to-point setups. Static keys are less secure in that they never change. If someone captures your traffic, and then gains your static key a year from now, they can decrypt the captured traffic. Setups that use certs re-key every hour by default |
| static_key_details | http://svn.openvpn.net/projects/openvpn/web/trunk/faq-static-key-explanation.txt for an explanation of how static key files are used |
| statickey | #1: you can use static keys by using --secret </path/to/key> #2: static keys only work for ptp links, not client/server. They also do not provide forward encryption. A forward-secure encryption scheme (such as openvpn uses with certs) protects secret keys from exposure by evolving the keys with time. #3: see !forwardsecurity for more info |

| tap | "bridge" is (#1) http://openvpn.net/index.php/documentation/faq.html#bridge1, or (#2) http://openvpn.net/index.php/documentation/miscellaneous/ethernet-bridging.html, or (#3) Bridging looks like a good choice to people who don't know how to set up IP routing, but to learn routing is generally far better., or (#4) useful for windows sharing (without wins server) and LAN gaming, anything where the protocol uses MAC addresses instead of IP addresses. |
| tcp | #1: Sometimes you cannot avoid tunneling over tcp, but if you can avoid it, DO. http://sites.inka.de/~bigred/devel/tcp-tcp.html Why TCP Over TCP Is A Bad Idea. #2: http://www.openvpn.net/papers/BLUG-talk/14.html for a presentation by James Yonan (OpenVPN lead developer) #3: if you must use tcp, you likely want --tcp-nodelay |
| tcp_nodelay | <EmperorTom> A good analogy is a bus depot. Drivers normally wait as long as possible to see if any more passengers show up. If you set TCP_NODELAY on the bus driver, he would leave the station as soon as someone got on board. It's faster for the one passenger, but you need a lot more big, ugly, smelly, slow buses on the road to meet demand. |

| timeout | if you see TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity) then your problem is likely one of the following: either the server isnt running, your client is connecting to the wrong ip/port/protocol, the server's firewall/nat has an issue, or the client's isp blocks it |
| tls-auth | "hmac" is (#1) The tls-auth directive adds an additional HMAC signature to all SSL/TLS handshake packets for integrity verification. Any UDP packet not bearing the correct HMAC signature can be dropped without further processing. The tls-auth HMAC signature provides an additional level of security above and beyond that provided by SSL/TLS., or (#2) openvpn --genkey --secret ta.key to make the tls static key , in configs: tls-auth ta.key # , 1 for client or 0 for server in the configs |
