Do these updated commands, like ping, require Roadshow? Or do they work with any of the available TCP/IP stacks?
The "wget" command should work with any AmiTCP API compatible Amiga TCP/IP stack, but "ping" and "traceroute" might not work with AmiTCP because the kernel APIs are significantly different in the BSD Unix versions which AmiTCP and Roadshow are based upon, respectively. This is why, for example, the AmiTCP "route" command does not work with Roadshow.
It's possible that the use of ICMP sockets on Roadshow is sufficiently different for both Roadshow's updated "ping" and "traceroute" commands that they might not work with AmiTCP. I haven't checked...
But, no harm done, you could download the new Roadshow demo version and give these commands a spin on your AmiTCP API compatible TCP/IP stack of choice. I don't mind, and neither do these commands
