Co:Z SFTP uses IBM Ported Tools OpenSSH (specifically, the "ssh" command) for its network connection.

This message is from Ported Tools ssh, and indicates an error from the "ssh-rand-helper" process. See the Ported Tools User's guide for more information.

The best thing you can do, if you can, is to set up ICSF to generate your random numbers. See "Using hardware support to generate random numbers" in the Ported Tools User's guide for more information.
