You can then install the RPM with the standard RPM -install command: - - rpm -ivh [binary-rpm] - -When you install the binary RPM, it will install -sample-scripts/openvpn.init, which can be used to -automatically start or stop one or more OpenVPN tunnels on system -startup or shutdown, based on OpenVPN .conf files in /etc/openvpn. -See the comments in openvpn.init for more information. - -Installing the RPM will also configure the TUN/TAP device node -for linux 2.6. - -Note that the current openvpn.spec file, which instructs the rpm tool -how to build a package, will build OpenVPN with all options enabled, -including OpenSSL, LZO, and pthread linkage. Therefore all of -these packages will need to be present prior to the RPM build, unless -you edit the openvpn.spec file. - -************************************************************************* - -TUN/TAP Driver Configuration: - -* Linux 2.6 or higher (with integrated TUN/TAP driver): - - (1) load driver: modprobe tun - (2) enable routing: echo 1 > /proc/sys/net/ipv4/ip_forward - - Note that (1) needs to be done once per reboot. If you install from RPM (see - above) and use the openvpn.init script, these steps are taken care of for you. - -* FreeBSD: - - FreeBSD ships with the TUN/TAP driver, and the device nodes for tap0, - tap1, tap2, tap3, tun0, tun1, tun2 and tun3 are made by default. - However, only the TUN driver is linked into the GENERIC kernel. - - To load the TAP driver, enter: - - kldload if_tap - - See man rc(8) to find out how you can do this at boot time. - - The easiest way is to install OpenVPN from the FreeBSD ports system, - the port includes a sample script to automatically load the TAP driver - at boot-up time. - -* OpenBSD: - - OpenBSD has dynamically created tun* devices so you only need - to create an empty /etc/hostname.tun0 (tun1, tun2 and so on) for each tun - you plan to use to create the device(s) at boot. - -* Solaris: - - You need a TUN/TAP kernel driver for OpenVPN to work: - - http://www.whiteboard.ne.jp/~admin2/tuntap/ - -* Windows XP/2003/Vista/7: - - OpenVPN on Windows needs a TUN/TAP kernel driver to work. OpenVPN installers - include this driver, so installing it separately is not usually required. - The driver source code is available here: - - https://github.com/OpenVPN/tap-windows - -************************************************************************* - -CAVEATS & BUGS: - -* I have noticed cases where TCP sessions tunneled over the Linux - TAP driver (kernel 2.4.21 and 2.4.22) stall when lower --mssfix - values are used. The TCP sessions appear to unstall and resume - normally when the remote VPN endpoint is pinged. - -* If run through a firewall using OpenBSDs packet filter PF and the - filter rules include a "scrub" directive, you may get problems talking - to Linux hosts over the tunnel, since the scrubbing will kill packets - sent from Linux hosts if they are fragmented. This is usually seen as - tunnels where small packets and pings get through but large packets - and "regular traffic" don't. To circumvent this, add "no-df" to - the scrub directive so that the packet filter will let fragments with - the "dont fragment"-flag set through anyway. - -* Mixing OFB or CFB cipher modes with static key mode is not recommended, - and is flagged as an error on OpenVPN versions 1.2.1 and greater. - If you use the --cipher option to explicitly select an OFB or CFB - cipher AND you are using static key mode, it is possible that there - could be an IV collision if the OpenVPN daemons on both sides - of the connection are started at exactly the same time, since - OpenVPN uses a timestamp combined with a sequence number as the cipher - IV for OFB and CFB modes. This is not an issue if you are - using CBC cipher mode (the default), or if you are using OFB or CFB - cipher mode with SSL/TLS authentication. |
