[might want to view this in a monospaced font]

I am running ssh 1.2.26 on Solaris 2.5.1 and 2.6 and I keep getting 
these in console & messages file:

Mar 24 14:04:26 www sshd[6646]: fatal: Local: Bad packet length 1077952576.
Mar 24 14:05:27 www sshd[6836]: fatal: Local: Bad packet length 1077952576.

... large scp's and rsyncs (over ssh) seem to freeze between two 
machines on different sides of a network. Machines on the same 
segments have no problems.


The network between the two machines who are talking looks like this:

100BT            6Mbps over OC3             100BT
------[Positron]================[Positron]-------------
 |                                           |
+----------+                              +----------+
| gate     |                              | jammer   |
| firewall |                              | firewall |
+----------+                              +----------+
 | 10BT                                       | 100BT
+-------+                                 +-------+
| waldo | <--source        destination--> | www   |
| 2.6   |                                 | 2.5.1 |
+-------+                                 +-------+

We used to have the two firewalls on the same segment, and this 
worked fine then. This leads to my own personal theory that maybe 
something on the Positrons is changing the packets from an MTU for 
100BT to a 6-Mb MTU (and back again?), perhaps screwing up something 
along the way? (That might explain why it only happens when copying 
larger files.)

Can someone tell me whether I might be on the right track on this? I 
am going to run some tests from different parts of the network when I 
get a chance, and maybe change the MTU on the interfaces to the 
lowest common denominator.

Thanks for any help anyone can give me.
