inability to connect with netware OpenSSH 3.7.1 to FreeBSD 4.5p1

and there are no other SSH resources on the net)


Hello,
 
Client is (some netware installation) running:
 
Local version string SSH-2.0-OpenSSH_3.7.1p2
 
Server is plain old FreeBSD 6.2-RELEASE running:
 
OpenSSH_4.5p1 FreeBSD-20061110, OpenSSL 0.9.7e-p1
 
 
When I attempt to connect from client (netware) to
server (freebsd) I see:
 
ssh -vvv user at host
 
<0> debug1: kex: client->server aes128-cbc hmac-md5

<0> debug1: ssh_dss_verify: signature error           
                         
<0> fatal: key_verify failed for server_host_key      
                         
<0> debug1: Calling cleanup 0xa69a0ec0(0x0)           
                         
<0> debug1: Calling cleanup 0xa6994630(0x0)

1                        
<0> debug1: SSH_NWExit(0) calling SSH_NetWareExit()
 
 
The key pieces of the error being:
 
 
<0> debug1: ssh_dss_verify: signature error           
                         
<0> fatal: key_verify failed for server_host_key 
 
 
So then I connect forcing version 1:
 
 
ssh -vvv -1 user at host
 
 
and I get:
 
 
<0> fatal: Selected cipher type <unknown> not
supported by server.
 
 
So if I specify DES:
 
ssh -vvv -1 -c des user at host
 
 
<0> fatal: Selected cipher type des not supported by
server.
 
 
Finally, I specify 3des, and I get no output at all:
 
ssh -vvv -1 -c 3des user at host
 
the command just completes and I get no output - as if
I did not run it at all.
 
 
Any suggestions ?  Has anyone connected from netware
to a recent OpenSSH 4.5.x server ?  This is one of the
newest, if not the very newest release distros of
OpenSSH for netware, so we are fairly up to date...
 
 
Thanks.
