I've just downloaded TRN from comp.sources.unix. 13 of its 14 parts
were coherent shell-archives but part 9's tail-end was wrong. This
was different to all the other parts which output a sequence number to
a temp file so as to keep the shars in order.
OK, I can get round that but it got me thinking. I wondered what
happened to corrupt the shar? Maybe the posting was corrupt in the
first place but my main worry is this:
How can I be certain that a shar archive is what it claims to be?
How do I know that it hasn't been interfered with along the net?
When some tempting piece of software lands up at my end of the net,
how do I know that it's safe to unpack, never mind compile & run?
Am I just being paranoid?

I also found the TRN posting to be a bit corrupt. ng.c seems to have a bit missing from the middle where the file was split between the two shar files. If anyone has a copy of ng.c (preferably with patch1 applied), could you please post it?

Well, Part09/14 was reposted and, while a complete shar file, it seemed to have nothing much to do with Parts 1-8,10-14. Part 08 did not continue into it and Part 10 did not continue from it. -- Bob Peirce, Pittsburgh, PA 412-471-5320 ...!uunet!pitt!investor!rbp rbp@investor.pgh.pa.us
