- rpmbuild -tb [tarball] - -This command will build a binary RPM file and place it in the system -RPM directory. 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 2.4. - -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 2.4 or higher (with integrated TUN/TAP driver): - - (1) make device node: mknod /dev/net/tun c 10 200 - (2a) add to /etc/modules.conf: alias char-major-10-200 tun - (2b) load driver: modprobe tun - (3) enable routing: echo 1 > /proc/sys/net/ipv4/ip_forward - - Note that either of steps (2a) or (2b) is sufficient. While (2a) - only needs to be done once per install, (2b) 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. - -* Linux 2.2 or Solaris: - - You should obtain - version 1.1 of the TUN/TAP driver from - http://vtun.sourceforge.net/tun/ - and follow the installation instructions. - - If you use OpenVPN on Linux 2.2 or 2.4 or Solaris, you may be - suffering from a bug which causes connections to hang under heavy load. - The symptoms are very similar to the MTU problems discussed frequently - in the OpenVPN mailing lists. But it turns out that this bug is not caused by - MTU problems. It's a bug in the tun/tap driver. A patch is provided here: - - http://openvpn.net/patch/tun-sb.patch - -* Solaris - - For 64 bit, I used the tun-1.1.tar.gz source and compiled it. - - Of course there is a but :) - In the tun-1-1\solaris\Makefile I changed a line so it compiles with 64 bit - - CFLAGS = $(DEFS) -m64 -O2 -Wall -D_KERNEL -I. - - I just added -m64 and it worked. - - The tun driver works fine as said previously, however we noticed there is a - minor problem when creating multiple tunnels on Solaris. - Mr Tycho Fruru changed the code in tun.c file where he locked the tun device - number to -1. This way it is impossible to specify the name of the tun device - but it is still possible to have multiple devices. - The modification will increment automatically meaning starting from tun0 ---> - tunX I know you are not responsible for the tun coding but if you think the - modification can be useful for you feel free to use it. - - http://openvpn.net/solaris/tun.c - -* FreeBSD 4.1.1+: - - 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 ships with tun0 and tun1 installed by default on pre-3.5 systems, - while 3.5 and later have 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. - -* Mac OS X: - - 2005.02.13: Angelo Laub has developed a GUI for OS X: - - http://rechenknecht.net/OpenVPN-GUI/ - - 2004.10.26: Mattias Nissler has developed a new TUN/TAP driver for - MAC OS X: - - http://www-user.rhrk.uni-kl.de/~nissler/tuntap/ - - Christoph Pfisterer's old TUN driver can be obtained at - http://chrisp.de/en/projects/tunnel.html -- note that it - is no longer being maintained. - -* Solaris9 Sparc/64 - - The kernel module for solaris - can be generated by adding the -m64 switch to a modern - gcc compiler (I'm using 3.2) The resulting kernel driver - needs to be manually copied to /kernel/drv/sparcv9/ and then a - reconfiguration reboot. (boot -r). - -* Windows XP/2003/Vista - - See domake-win for building instructions. - See INSTALL-win32.txt for usage info. - - See the man page for more information, usage examples, and - information on firewall configuration. - -************************************************************************* - -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. -- cgit v1.2.3
