I am trying to complete ssh2 connection between HP-UX and CoreFTP. The host key authentication fails with signature didn't match. See below output. I can connect to this CoreFTP from my Windows desktop, and connect to a multitude of other servers from the HP-UX system as well, but have encountered this error on this particular connection.
Has anyone encountered this and have a resolution. Thx.

Experts,
We are trying to make a key-based authentication from Server A to Server B.
Server A is installed with openshh. Server B runs "Sun_SSH_1.1".
Server A's rsa2 public key has been added into the server B's authorized_keys.
We are sure that permission settings of the files and folders in... (1 Reply)
Hey all, I have a request from a third party that will be setting my firm up for an account so we can sftp files to their server in a Production environment. I know where the public keys are located on our Red Hat Linux envronment. I was going to ftp the keys from the Linux environment over to my... (2 Replies)
Hey all,
I have a script that I use for some automated installs. Unfortunately for the script to work the server that it's running from needs to have host-key authentication setup to the target server. If it isn't setup beforehand and the script is executed the install partially completes and... (1 Reply)
It seems I can do ssh <IP> but not ssh <hostname>
If I try to ssh to hostname I get the error - No DSA host key is known for host1 and you have requested strict checking.
Host key verification failed.
Where do I set up the DSA keys? Is it ssh_known_hosts?

I had generated a ssh2 key on my AIX box, to receive files from other AIX and Linux systems.
Key Name: id_ssh2_server.pub
However this ssh2 key (both public and private keys) has been overwritten, while I was generating another ssh2 key. Now the earlier configured target systems are not able... (3 Replies)
Hi,
I got instructions from Security audit team for Solaris-10 server. They mentioned - "The sshd configuration on the host supported weak host keys and allowed password authentication on Solaris server. Enable stronger keys (2048 or 4096 bit)".
I am not clear enough, what they mean by weak... (7 Replies)

ssh-keysign
ssh-keysign(1M)ssh-keysign(1M)NAME
ssh-keysign - ssh helper program for host-based authentication
SYNOPSIS
ssh-keysign
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication
with SSH protocol version 2. This signature is of data that includes, among other items, the name of the client host and the name of the
client user.
ssh-keysign is disabled by default and can be enabled only in the global client configuration file /etc/ssh/ssh_config by setting Host-
basedAuthentication to yes.
ssh-keysign is not intended to be invoked by the user, but from ssh. See ssh(1) and sshd(1M) for more information about host-based authen-
tication.
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key
/etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, readable
only by root, and not accessible to others. Because they are readable only by root, ssh-keysign must be set-uid root if host-based
authentication is used.
ssh-keysign will not sign host-based authentication data under the following conditions:
o If the HostbasedAuthentication client configuration parameter is not set to yes in /etc/ssh/ssh_config. This setting cannot be overri-
den in users' ~/.ssh/ssh_config files.
o If the client hostname and username in /etc/ssh/ssh_config do not match the canonical hostname of the client where ssh-keysign is
invoked and the name of the user invoking ssh-keysign.
In spite of ssh-keysign's restrictions on the contents of the host-based authentication data, there remains the ability of users to use it
as an avenue for obtaining the client's private host keys. For this reason host-based authentication is turned off by default.
