hi to all
I have tryed to install openvpn but i can't
i was in yellow panel=> pli packege managment=>feed:official=>
There are 3 files
"openvpn_2.0.2-r0_powerpc"
"openvpn-dbg_2.0.2-r0_powerpc"
"openvpn-doc_2.0.2-r0_powerpc"
i have checked them , install them but there are not appearing in installed packages.
Do i am missing something?
thanks in advance

see what happens when you try to install from the commandline:

ipkg update && ipkg install openvpn

you should end up with the openvpn binary installed (it is a commandline tool)

check
ipkg files openvpn

to see what it installed. Possibly an initscript as well, I'm not sure.

It shows me that:
Package openvpn (2.0.2-r0) is installed on root and has the following files:
/usr/sbin/openvpn
/etc/init.d/openvpn

Where can i find the config files so to setup vpn connection with another dm600?

thanks

[pieterg]

see what's inside /etc/init.d/openvpn, might give you clues were to put your configuration

Hi again
I have made some progress since last 2 days
i have setup the config files but an error keep me from finishing my job

The message:
Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2)

my config file is this:
local 192.168.1.103
proto udp
dev tap
ca ca.crt
cert server.crt
key server.key
dh dh1024.pem
server 192.168.2.0 255.255.255.0
ifconfig-pool-persist ipp.txt
keepalive 10 120
cipher BF-CBC # Blowfish (default) encryption
comp-lzo
max-clients 100
persist-key
persist-tun
status openvpn-status.log
verb 6


What can i do?
Thanks

[pieterg]

you have to install tap/tun drivers
try:
ipkg update
ipkg list *tap*
ipkg list *tun*

to find out what they might be called
(probably kernel-module-tun and perhaps kernel-module-tap is also available. You need only one type, tap or tun)

[evagelos]

I am very sorry but i do not know very much about linux.
In windows i would put the name of my Network Adapter ex: vpn
How can i find the name of adapter?
thanks

Just execute the commands on your Dreambox as pieterg suggested. Anyway, I tried it for you and you need this command:

ipkg update
ipkg install kernel-module-tun

to install the TUN kernel drivers.

[evagelos]

Thanks.
Now it seams to work just fine

THANKS

Any suggestions?

[pieterg]

is the tun driver loaded?
(check with lsmod)

if not, modprobe tun

[Basiliss]

Thanks for the quick reply,that worked perfectly!

[Basiliss]

How can i make it perm?Should i include this in an init script?

[pieterg]

yes, I think /etc/init.d/openvpn would be the sensible place to load the driver
(assumed that you start your connections from this script, at bootup)

[Basiliss]

Thanks again!

[atma]

Well apparently openvpn init script does not handle tun device. There should a file called /etc/modules.d/kernel-2.4 there which handles the modules... Instead the man page writes about a file /etc/modeutils which does not exist on my current install PLi-Jade 3.

I put the the line "modprobe tun" on the "start stop" script in order to make it work...

[lincsat]

root@dm600pvr /etc/openvpn # openvpn client.conf

Don't know if this is significant but you start with this command:

root@dm600pvr # /etc/openvpn/openvpn start
