To access the SSH setup screen, choose MANAGEMENT/NETWORK/SSH Setup . The
window will open to the Host Keys tab by default.
If you want to change the key length of any host key, enter the desired length in the text
field corresponding to the length you wish to change. See "Deleting Host Keys" on the pre-
vious page.
Check the Regenerate All Keys box.
Click the Submit button at the bottom of the page.
The Key Type/Status/Action table will temporarily disappear while the SecureSync regen-
erates the keys. The Host keys are generated in the background. Creating RSA and DSA
keys, each with 1024 bits length, typically takes about 30 seconds. Keys are created in the
order of RSA, DSA, ECDSA. SecureSync will generate all 3 host keys, the RSA key, the
DSA key and the ECDSA key.
Delete any of the keys you do not want. See "Deleting Host Keys" on the previous page.
NOTE – If the unit is rebooted with host key creation in progress, or the unit is booted
and no host keys exist, the key generation process is restarted. The key generation
process uses the previously specified key sizes.
