Configuring the SSH
client
A variety of SSH client software are available, such as PuTTY and OpenSSH. For an
SSH client to establish a connection with an SSH server, use the following
commands:
Table 312 Configuration tasks for using a client software
Tasks
"Generate a client key"
"Specify the IP address of the Server"
"Select a protocol for remote connection"
"Select an SSH version"
"Open an SSH connection with publickey
authentication"
"Open an SSH connection with password
authentication"

Selecting the protocol for remote connection as SSH. Usually, a client can use a
■
variety of remote connection protocols, such as Telnet, Rlogin, and SSH. To
establish an SSH connection, you must select SSH
When a Switch 4210 acts as the SSH server, select 2.0 for the clients.
■
Specifying the private key file. On the server, if public key authentication is
■
enabled for an SSH user and a public key is set for the user, the private key file
corresponding to the public key must be specified on the client. RSA key pairs
and DSA key pairs are generated by a tool of the client software.
The following takes the client software of PuTTY, PuTTYGen and SSHKEY as
examples to illustrate how to configure the SSH client:
Generate a client key
To generate a client key, run PuTTYGen.exe, and select from the Parameters area
the type of key you want to generate, either SSH-2 RSA or SSH-2 DSA, then click
