I scanned the Internet.  Indications were administratively prohibited
either meant "AllowTCPForwarding" was no in the sshd_config file on
machine B or the target machine (machine C) was not being found.

It would surprise me if one cannot do ssh -N -L 8080:C:22 B
but perhaps the name, C, is not being resolved to an IP address.

Could you try the actual IP address for machine C in the command?

Otherwise, I fear the problem is AllowTCPForwarding on machine B.
