SSH problem: failing in S_RLOGINCHK

SSH problem: failing in S_RLOGINCHK

Post by J Eric Brack » Fri, 04 Oct 1996 04:00:00



I'm having trouble getting SSH up and running:

I've built SSH on two machines, one SunOS 4.1.3 and the other AIX 4.1.
I want the AIX machine to act as 'server' for shell requests from the
SunOS machine.  I am not permitted to run as root on the server, so I
start it up using a different port (I tried 7222).

The authentication always seems to fall back to a simple password
exchange, apparently failing the rhosts + RSA method, despite my best
efforts (I think I've exchanged the right public keys.)

When I run sshd with degugging on, this is what happens:

./sshd -d -p 7222 -f my_server_config -h my_ssh_host_key
debug: sshd version 1.2.13 [rs6000-ibm-aix4.1.3.0]
debug: Initializing random number generator; seed file .ssh-server/ssh_random_seed
log: Server listening on port 7222.
log: Generating 768 bit RSA key.
log: RSA key generation complete.
debug: Server will not fork when running in debugging mode.
log: Connection from 192.XXX.XXX.XXX port 2805
debug: Client protocol version 1.3; client software version 1.2.13
debug: Sent 768 bit public key and 1024 bit host key.
debug: Encryption type: idea
debug: Received session key; encryption turned on.
debug: getuserattr S_RLOGINCHK failed.                  <-- what is this?
fatal: Connection closed by remote host.
debug: Calling cleanup 0x20000ee4(0x0)

Any ideas what's wrong?

1. SSH to/from localhost works but ssh from remote fails (receives "Connection refused")

I recently upgraded to openssh-3.1 and now sshd refuses connections
from remote hosts.  Running "ssh localhost" works fine.  Trying to ssh
from remote system fails.  I have tried to force ssh2.  I verified the
remote host is not blocked in hosts.deny and that hosts.allow is
ALL:ALL.  I also verified that ipchains is not blocking requests to
port 22 (and iptables is not running).  There are no errors in
/var/log/secure.  The /etc/ssh/sshd_config is all defaults.

Here's the output running ssh client verbose from a remot host:

bash-2.03$ ssh -v -2 dhaller2.workstation

Any ideas?
