I installed ssh-keygen via:

opkg install openssh-keygen

But when I try to generate a key I get the following error (guess i'm missing something):

 Error relocating /usr/bin/ssh-keygen: explicit_bzero: symbol not found

Hello,

Versions from the OpenWRT repositories appear to be incompatible, you have to generate your own openssh-keygen (and openssh-client, openssh-client-utils ...) using the SDK.

Thanks, I figured it out after all. The problem is with dropbear, thats installed by default. When you install openssh-keygen something breaks (so either you need to remove dropbear and replace it with openssh or use dropbear). With dropbear you can also generate keys: dropbearkey

True but pretty much useless you won't be able to ssh/scp/... to other *nix boxes with this key the crypto options of dropbear are too limited you'll need the full-featured openssh for that.

Well, yes I understand.

I just need to created some keys (thats why I first installed ssk-keygen, didn't realize dropbear was used) so I could setup a reverse ssh tunnel to my centos server. That works now fine with dorpbearkey function.
