semmar_1 — Tue, 11 Nov 2008 12:34:53 GMT

hello all
we have a sun solaris unix machine
we do
1 compress file
2 crypt key
3 transfer the file crypted to an HP8400 hpux 11.11
4 decrypt the file with the same command and same key (crypt and K120 key )
5 uncompress the file an error occure
the file is not in a compressed file
please help me

Transfer how?

Do decrypt and uncompress work on the Solaris
system if you don't "transfer the file"?

Hi Semmar,

After decrypt the file on HP-UX, what is the output this command?

#file

1 transfer the file with ftp
2 I decrypt the file with the command crypt and the result is a file.Z the file compressed before .
thanks

ASCII? Binary? Actual commands?

Does that answer anyone's question(s)?

I assume this also fails if you skip the compress steps?

You might want to see if cksum and crypt produce the same outputs on the same inputs.

First pick a file, copy in binary to the other machine and use cksum on the original and the crypt versions. If they don't match, then that's the problem.

(Any reason you use compress vs gzip?)

Still wondering about that.

Or, if you transfer it to the HP-UX system,
and then transfer it back?

You first.

By the way, this works fine for me between:

sol# uname -a
SunOS sol 5.10 Generic_127127-11 sun4u sparc SUNW,Ultra-60

and:

dy # uname -a
HP-UX dy B.11.11 U 9000/785 2012616114 unlimited-user license

Perhaps it would be useful to show _exactly_
what you do instead of providing only a vague
description of what you do. "ls -l" before
and after might be interesting, too.

> the file is not in a compressed file

I'd bet that the actual message looks more
like:

: not in compressed format

This inaccuracy, and the fact that it works
for me, lead me to doubt the accuracy of the
rest of your (vague) description of what you
did.

helo

yes the decrypt and uncompress work on the Solaris system when we do transfer from solaris to solaris server.

when we do it from solaris to the HP-UX system it doesn't work

Still true.

As I said, it worked for me. I still don't
know exactly what you did, or exactly what
happened when you did it. "[I]t doesn't
work" is not a useful problem description.
You've provided no useful information to
work with. How do you expect anyone to guess
where the problem lies?

you should compare a cksum and size of all versions of the files taken at every steps.
cksum at step 2.5 and 3.5
and
cksum at 1.5 and 4.5

Then you will know if the file differ after transfert if 2.5 and 3.5 are different
or if it is crypt if 1.5 and 4.5 defers

you may also get the crypted file back to sun server and try the decrypt and uncompress there.

Also is the size of the file larger than 2G?

then try cryp thefileuncrypted
