Hi,

I'm happy to hear that the driver worked fine.
Please let me know if there's any problem on it.

[Openvpn-devel] [PATCH] TAP interface support for Solaris/OpenSolaris

[Kazuyoshi Aizawa]

Hi,

I've attached a patch for tun.c which includes support for tap
interface for solaris/opensolaris.
The code is based on OpneVPN 2.1.1. And it has a routine to
plumb/unplumb tap interface like ifconfig command.

tap driver for solarsi/opensolaris is here:
  http://www.whiteboard.ne.jp/~admin2/tuntap/

Thanks,

Kazuyoshi

[Openvpn-devel] ipv6 support of tun for solaris/opensolaris

[Kazuyoshi Aizawa]

Hi,

I added ipv6 support to tun driver for solaris.
Full source tar ball and patch against original universal tun/tap driver is
available here.

 http://www.whiteboard.ne.jp/~admin2/tuntap/

In response to this change, I revised the patch against openvpn and set
'ipv6_explicitly_supported' to true. Please find attached patch.
The patch is based on OpenVPN 2.1_rc21, and it also includes code to handle
tap driver for solaris.
With above tun driver and attached patch, solaris/opensolaris is capable to
forward ipv6 packets through tun interface.

Thanks,

Kazuyoshi

Re: [Openvpn-devel] Solaris questions

[Kazuyoshi Aizawa]

Hi Carsten,

Thank you for the notice.
It would be nice if solaris itself support tun/tap driver.
But at present, I believe my modified tun/tap driver still be usable
to work with openvpn.
Please try this if interesting, and let me know if you find any defects.

Thanks,

Kazuyoshi

Re: [Openvpn-devel] Solaris questions

[Kazuyoshi Aizawa]

Hi,

I modified the build scripts of tun/tap driver for Solaris and
uploaded it to web site below.

  http://www.whiteboard.ne.jp/~admin2/tuntap/

Now, it is capable ..
   to build 32bit module on 64bit environment by using --disable-64bit
option to configure script.
   to checks if ld command is GNU ld or Solaris bundled ld. And then
appends appropriate option for GNU ld.
   to specify target install directory using DESTDIR macro to make command.

Thanks Victor, for the info and help.

Hi Victor,

Thank you very much for the patch and info.
It is really helpful.
I intend to apply it to my script.
And I'll consider to provide tun.c as a patch.

Thanks,

Kazuyoshi

Re: [Openvpn-devel] Solaris questions

[Kazuyoshi Aizawa]

Hi Victor,

Could you please post the script once you have built drivers for your package?
So that I can update my script as well.
I've wanted to make script to be capable to build drivers on various
platforms. But I don't have enough systems which can use for test.
So if you would share your information, it would be appreciated.

Thanks,

Kazuyoshi
