Hi team, I have finally gotten some more time to resume stack testing. I am <still> testing ping. I have some questions: What does the -D option do? How would I test it? What does the -d option do? How would I test it? How should the -L option be invoked? Im getting a setsockopt error -2147483643 no matter what I do. What does -n do? I get the same output using the -v (verbose) switch as I do without it. Is this ok? Im assuming I cant test -r or -R until 'route' is fixed. Is this correct? Otherwise, all other single command line options have been tested. Thanks in advance for any responses... Brennan Cleveland
