I'm thinking of exanding the DNS with Hamaci. However, Hamaci requires tuntap support in the kernel and I don't know much of the kernel. Is tuntap part of the 2.6.0 kernel in the DNS? If, so how do you enable tuntap? If not, any ideas how to make it part of the DNS (modules?)?

well actually I've never heard of hamaci before, but I'm using openvpn with the tun/tap interface, using my compiled tun.ko module...

http://dev.skcserver.de/dns323/tun.ko

just insmod the module and create the tun or tap device...

mkdir /dev/net
mknod 600 /dev/net/tun c 10 200

Thanks. I must confess that I'm impressed with your swift respone and what you apperently have accomplished. I'm curious about your setup and how you compile for the DNS. Do you use the cross-complie toolchain from D-Link/GPL or do you use debian sarge on the DNS?
I don't currently have the option to compile for the DNS and are curious which is the best/simplest way to do it. I'm not a complete noob, but cross compiling and kernel-things is not my bag....

Any help is apprechiated.

Thanks/Apan

I'm compiling on the dns device itself...

I've followed the "install debian" thread on this forum to install the debian base system on the raid-volume. afterwards I downloaded the linux kernel from dlink's ftp site (ftp://ftp.dlink.com/GPL/dns323/) and compiled some modules (usb-storage, tun etc.).
since I was now able to access a usb memory stick I moved the complete debian etch from my hdds to the usb stick and modified the fun_plug script to mount the usb device on boot and chroot to that.

I think that's definately not the easiest way, but my "dream" is to boot entirely from the usb device using a custom kernel ;-)

hamachi is not a open source program and it is only available for x86 and ppc, so you cant use it on DNS323.
You might want to try openvpn instead

levring · 2007-01-31 15:54:35

It seems it already had been compiled on a ARM.

Looks like you where right, although you need to chroot into libc environment to use this binary.

This is a great tip. They really should be collected on a wiki, as a forum isn't the best way to quickly find things.

KRH · 2007-01-31 17:58:30

wiki will be online soon.

levring · 2007-01-31 21:28:40

IMO it would be a lot easier to install Hamachi, then OpenVPN.. Especially after i took a look at the guides on the net.

Is there some way simple to setup a encrypted VPN connection ? - The reason im askin is that the SCP can run at a max of ~10mbit

I'm getting very confused here. Have now, finally, my debian up and running. But; the files in the Nokia distribution puzzles me.

I started with a simple test, in the chrooted environment:

NAS:~# ./tuncfg
-bash: ./tuncfg: No such file or directory

NAS:~# ./hamachi
-bash: ./hamachi: No such file or directory

Then I compiled the tuncfg.c with gcc tuncfg.c -o tuncfg:

NAS:~# ls -l
total 244
-rwxrwxrwx 1 501 501 197916 Jul 11 2006 hamachi
-rwxr-xr-x 1 root root 20328 Feb 2 09:32 tuncfg
-rwxrwxrwx 1 501 501 8537 Jul 11 2006 tuncfg.c
-rwxrwxrwx 1 501 501 9444 Jul 11 2006 tuncfg.org

Fine, that one executes (after insmod and mknod) ok:
NAS:~# ps -edf | grep tun
root 16328 1 0 1970 ? 00:00:00 ./tuncfg
root 16461 15990 0 1970 ttyp0 00:00:00 grep tun

But; I cannot figure out why the original doesn't work....really:
NAS:~# file tuncfg
tuncfg: ELF 32-bit LSB executable, ARM, version 1 (ARM), for GNU/Linux 2.2.0, dynamically linked (uses shared libs), not stripped
NAS:~# file tuncfg.org
tuncfg.org: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Linux 2.4.17, dynamically linked (uses shared libs), stripped

NAS:~# objdump -af tuncfg

tuncfg: file format elf32-littlearm
tuncfg
architecture: arm, flags 0x00000112:
EXEC_P, HAS_SYMS, D_PAGED
start address 0x00008898

NAS:~# objdump -af tuncfg.org

tuncfg.org: file format elf32-littlearm
tuncfg.org
architecture: arm, flags 0x00000112:
EXEC_P, HAS_SYMS, D_PAGED
start address 0x00008894

Any clues? Why do I get "No such file or directory" ? Is there some way to re-link into static or to relocate the symlinks?!?

edit: Some more findings: The debian sarge distro compiles to GLIBC_2.0 and hamachi appearently requires GLIBC_2.4. I think we're stuck on this binary unless someone knows how to re-link it to a static binary, which will not be doable on the debian sarge if I understand things right. It appears as if the binary compiled to SYSV ARM differ from the ARM variant. :-(
