Generate /etc/ssh/ssh_host_dsa_key
A host public-key pair (1536-bit RSA) is always generated during the installation of SSH Tectia Server. You only need to regenerate it if you want to change your host key pair.
The command-line tool ssh-keygen-g3
can be used to generate the host key pair. It can be used for creating the user key pairs as well.
May 14, 2013 Generating server side SSH keys. For anyone ELSE who has a CentOS server and needs to generate new keys and fingerprints (for, say, cloning VMs in KVM, Xen, VMware, Hyper-V, etc.
On Unix, to (re)generate the host key, give the following command with root privileges:

-P
indicates that the key has an empty passphrase
-H
indicates that the key pair is stored in the default host key directory
On Windows, to (re)generate the host key, give the following command:
This will generate a 2048-bit DSA key pair (without a passphrase) and save it in the default host key directory (/etc/ssh2
on Unix, 'C:Program FilesSSH Communications SecuritySSH TectiaSSH Tectia Server
' on Windows) with the names hostkey
and hostkey.pub
. For more information on the key generation options, see ssh-keygen-g3(1).
Generate /etc/ssh/ssh_host_dsa_key Address
After the new key pair has been created, run ssh-server-config-tool
to reconfigure the server. See ssh-server-config-tool(8).
The ssh-keygen program can be used for generating additional host keys or for replacing existing keys. Known Host Keys. SSH clients store host keys for hosts they have ever connected to. These stored host keys are called known host keys, and the collection is often called known hosts. In OpenSSH, the collection of known host keys is stored in /etc/ssh/knownhosts and in.ssh. How to regenerate new ssh server keys This is an unusual topic since most distribution create these keys for you during the installation of the OpenSSH server package. But it may be useful to be able generate new server keys from time to time, this happen to me when I duplicate Virtual Private Server which contains an installed ssh package. The basic format of the command to sign user's public key to create a user certificate is as follows: ssh-keygen -s causerkey -I certificateID idrsa.pub Where -s indicates the private key used to sign the certificate, -I indicates an identity string, the certificateID, which can be any alpha numeric value.It is stored as a zero terminated string in the certificate.

The private key of the server must never be readable by anyone but |
