SSH server version 2 support

Collect one public key of each key type (DSA and/or RSA) from each client to be granted access to
the Brocade device and place all of these keys into one file. This public key file may contain up to
32 keys. The following is an example of a public key file containing one public key:

NOTE

Each key in the public key file must begin and end with the first and last lines in this example. If your
client does not include these lines in the public key, you must manually add them.

SSH server key generation time

The time range to initially generate SSH server keys varies. Refer to

Table 35

for initial SSH server

key generation time ranges.

Providing the public key to clients

If you are using SSH server to connect to a device from a Linux or OpenSSH system, you may need
to add the device’s public key to a “known hosts” file; for example, $HOME/.ssh/known_hosts. The
following is an example of an entry in a known hosts file.
