Symlinking applets

[Jorge Oliveira]

Hello. I used to use your apps in a CM7, and worked flawlessly.

Now I have an Xperia J, stock rom, 4.1.2 latest FW. It's rooted and I have busybox installed in /system/xbin.

I'm trying to install openvpn, but I'm having trouble connecting to my server.
For now, after some search, I need help symlinking two applets: ifconfig and route. They both are symlinked to toolbox. I need then to be linked to ifconfig and route that are in xbin (I believe this is what has do be done... I've tried this in terminal, but gives me a "file already exists" error).

ln -s /system/bin/ifconfig /system/xbin/ifconfig

In log, the final parts says:;

/system/xbin/busybox ifconfig tap0 192.168.1.200 netmask 255.255.255.0 mtu 1500 broadcast 192.168.1.255
MANAGEMENT: client disconnected
Linux ifconfig failed: external program fork failed
Exiting

And int the openvpn setting, is af for a split second I received an IP and the disconnects.

Can you tell me what I have to do in order to when openvpn calls ifconfig, it goes to the busybox ifconfig?

Thanks
