It was thus said that the Great Jules Richardson once stated:
Sure - I suppose I've just surprised that there isn't already something in
the public domain that can't flood a system, generate bogus/corrupt packets
etc. in order to test a stack out; it still wouldn't catch all bugs of
course, but might give a faster response to most problems than asking the
list.
Have you tried lookint at nmap?
Yeah, telnetting from a GUI shell in linux gives me a
type of 'xterm', but
telnetting outside of X just shows a type of 'linux'.
Oh, what is the deal with backspace/delete? Backspace does nothing, whilst
delete echos some form of control code to the screen. ctrl-H seems to work
as the erase character, though (and genuinely does erase from the string
that gets sent to the server upon <return>). Is the PCjr doing something
non-standard with the handling of such keys, or is it just that other
telnet servers generally hack such keypress processing to accommodate
modern clients?
Well, the Linux kernel expects the erase key to be ASCII 127, and has the
backspace key generate said character. The default xterm expects the erase
key to be ASCII 8 and doesn't know how to handle ASCII 127 that the
backspace key under Linux sends. And it drives me nuts!
-spc (And there are enough programs under Linux that will respond the same
to both, but there are also plenty of exceptions ... )
