I'm trying to copy a ~80 MB TAR file between two linux systems on the
same network, from system1 to system2. The resulting file on system2
has the correct file size, but contains some garbled characters, and
doesn't pass the checksum test. Here are the machine stats:

--- SYSTEM 1 ---
uname -a:
Linux system1 2.6.18-92.1.6.el5 #1 SMP Wed Jun 25 13:49:24 EDT 2008
i686 i686 i386 GNU/Linux

ssh -V:
OpenSSH_4.3p2, OpenSSL 0.9.8b 04 May 2006

cksum scripts.tar:
1207994514 80220160 scripts.tar

--- SYSTEM 2 ---
uname -a:
Linux system2 2.6.16.60-0.21-smp #1 SMP Tue May 6 12:41:02 UTC 2008
x86_64 x86_64 x86_64 GNU/Linux

ssh -V:
OpenSSH_4.2p1, OpenSSL 0.9.8a 11 Oct 2005

cksum scripts.tar:
3359577481 80220160 scripts.tar


I'm executing: "scp scripts.tar system2:/home/fischega". Has anyone
ever seen anything like this before? This has me totally baffled.

Thanks,
Greg

What are the garbled characters you mention? They probably contain a clue.
How repeatable is it?

The first thing I would do is try other checksum tools (such as "openssl sha1")
in case the two cksum programs disagree on the same data.

Yes, I have. Bad memory or bad disk.

Or broken TSO implementation.
