ssh on ppc 405gp?

ssh on ppc 405gp?

[Dave Strout]

Has anybody succeeded in getting ssh to work on a 405GP machine?  I've
checked the archives, and seen a couple of reports of problems, but no
solutions.

I get the following error when trying to connect between a ppc machine
and an intel machine in either direction:

Received disconnect from 192.168.1.2: 2: Corrupted MAC on input.

If I ssh from the ppc to the ppc via 'localhost', it works.  That makes
me think that it's something to do with either byte ordering of
structure alignment, but I don't have any thoughts beyond that...  Any
suggestions on how to tackle this are welcome.

thanks,
dave.

Yes we ship ssh on all of our targets.  And it works correctly.  I have not seen
that message before, so I don't have any suggestions for you.. Sorry.

Dave,

Not sure what's going on in your case, but I've had it working fine for
the longest time.

What versions of distribution, kernel, ssh, etc. are you running?

I have seen this problem before.  It was happening a few months ago, and
hasn't happened since!

We use ssh to get to our ppc405h.  The temporary workaround for this
problem was to use a different mac protocol.  I believe the default is
2, so we tried 1, and it worked!  Here's the command:

ssh -1 192.168.25.35

Hope this works for you.

Jeff

Jeff,

Thanks for the lead.  I've actually tried that, and I get:
Disconnecting: Corrupted check bytes on input.

I'll keep playing with it.  If anybody has a generated Makefile for
openssl / openssh on the 405, I'd love to see it & see what the
differences are.  I'm thinking it's most likely in my config, given that
there exists at least one working example...

thanks,
dave.

Are you absolutely sure that your network interface (and the rest  of
the  system, like RAM) is working correctly? This looks somewhat like
data corruption...

Best regards,

Well, I can run tcpdump on either interface with no issues, so I'm
pretty sure everything is running OK.  In fact, I can tcpdump on the ppc
box for port 22 while I try it, and all the tcp checksums are OK, so I
don't think it's at the hardware / driver layer.

I'll go through and add some debugging code to see where / what is wrong
with the packets.

thanks,
dave.
