"cryptodev: un-supported command" when performing SSH operations

thirun · 07-01-2014, 06:11 AM

hi All,

I had observed the message "cryptodev: un-supported command" whenever I connect to target (The custom Embedded Linux)through SSH or telnet from Host Linux PC.

I had been googling for a while, but didn't get an appropriate solution for that.

What may be the issue? and how can I fix it.

Thanks And help will be highly appreciated.

This is only a guess, but I think your client and server are using different versions of openssh and openssl. Either your client or server has been compiled with cryptodev and the other has not. Perhaps you need to force the one with cryptodev not to use it for this particular connection. I don't know how you do that.

Thank you for suggestion Padeen, how to disable the criptodev option ?
