[gentoo-embedded] GNAP+VPN=PROBLEMS

[João Brázio]

[-- Attachment #1: Type: text/plain, Size: 652 bytes --]

Dear all,

I've been trying to configure GNAP as a VPN server without any success.

I want to allow 10 clients connected to the VPN server at the same time and
each one of them should have a different local IP address. This is possible
to do with a bridge.
I need to create br0 bridge with eth0 with tap0. The problem is that I can't
see the interfaces when I do ifconfig -a altought i can see /dev/net/tun so
I think TUN/TAP module is loaded.

Can this be done with a vanilla GNAP system ?
How is supposed to use the USE_VPN flag on GNAP, p2p VPN or a Server-to-many
solution ?

Thanks in advance.

João Brázio.

This is also possible to do without a bridge, using OpenVPN 2.0 "server"
mode. See http://openvpn.net/howto.html

GNAP vanilla kernel is missing bridge support.

USE_VPN triggers the use of OpenVPN. It supports both modes.

Dear Thierry,
It works great but now I've got another problem, I'm trying to compile GNAP
with nylon, a sock proxy and the following error occurs:

Re: [gentoo-embedded] GNAP+VPN=PROBLEMS

[Natanael Copa]

I'm not sure if this is the proper place to suggest this but, anyway...

I have a bootable proof-of-concept CD, build from gnetoo-embedded, that
probably could do what you want without you needing compiling anything.

fetch latest iso from http://jv.lmdata.org/alpine/hardened/isoimages/

This is totally undocumented (still alfa, but I think you should be able
to use it). All runtimes are installed in RAM so you need at least 64MB,
probably more.

boot the cd.

configure your network (debian/busybox style)
in /etc/network/interfaces. You can install nano or vim runtimes for
that with:

  apk_add openvpn

(You migh want to install dhcpcd or pump for dhcp. busybox internal
doesnt work because of no /share/ directory containing the scripts)

install openvpn runtimes:

  apk_add openvpn

configure openvpn (you might want to install bash for running the
openvpn scripts: apk_add bash)

bridgeutils are available with:

  apk_add bridge-utils

shorewall is available with:

  apk_add shorewall

Now as soon you reboot you would lose your configs so you would want to
store it on floppy or usb.

To add files to the save-to-writeable-media-list use:

  lbu_add FILE...

for example:

  lbu_add /etc/resolv.conf /etc/network/interfaces /etc/ssl /etc/openvpn

To really preform the write to floppy, use:

  lbu_commit floppy

You could store configs to usb stick too but then you will need usbd.

  apk_add usbd
  /etc/init.d/usbd start
  modprobe ub
  lbu_commit usb

Now next reboot, everythign in the lbu_add'ed files will be restored and
all pacakges installed will be reinstalled during boot.

make symblinks in /etc/rc2.d and add those links to local backup list
with lbu_add and the services will be started too.

For manpages on apk_add apk_delete and friends, visit
http://apk-tools.sf.net

I know atleast one person using this cd for openvpn.

Try :

# chroot /var/tmp/catalyst/tmp/gnap/grp-x86-20051228 /bin/bash
# emerge -av nylon libevent

And see how it works. One of those ebuilds might have some
uclibc-related problems.

Also this doesn't sound too good :

That name for a file is only created with a flat_list cache backend, 
specifically when it's doing an update to an existing entry (kind of a 
duh there considering the name, I know).

The algo is roughly
f=open(tmp_update_entry)
write to it
close it
utime it (reset mtime)
rename(tmp_update_entry, update_entry) 

Hence the 'offhand'.  Don't know if it's rename or utime that's not 
defined- just know that those are the only two syscalls that could 
sanely trigger that (failed update will trigger an unlink, but I'd be 
amazed if that call was missing).

OK.. I'm getting out of ideias.

Dear Brian,

The function not implemented is "utime", is this a known bug ?

# cat test.py
import os,time
f = 'foobar'
a = file(f, "w")
a.write("a")
a.close()
os.utime(f, (long(time.time()), long(time.time())))

# python test.py
Traceback (most recent call last):
  File "test.py", line 7, in ?
    os.utime(f, (long(time.time()), long(time.time())))
OSError: [Errno 38] Function not implemented: 'foobar'

Nice catch !
How do I update them according to my running kernel ? (A little bit
offtopic..)

probably by pointing /etc/make.profile to a 2.4 profile.

emerge kernel-headers
emerge uclibc

I believe that should be enough.

Not sure that would work with GNAP: it builds a 2.6 system so you will
end up with a 2.6-based chroot... What you need is use a 2.6 kernel on
the GNAP build host... or use a 2.4 profile and run Catalyst all by
yourself without GNAP.
