Introduction

Enabling secure management via Secure SHell (SSH) or Secure Sockets Layer (SSL/HTTPS) on the S-Series is a

four-step process. SSH and SSL both provide an encrypted transport session between the management station and

switch.

1. Generate the SSH keys or SSL certificates offline.

2. Copy the SSH keys or SSL certificates to the switch using TFTP.

3. Enable the secure management server (SSH or HTTPS) on the switch.

4. Disable the insecure version of the management server (Telnet or HTTP).

If you received this document as part of a .zip file, the file should contain two directories: ssh and ssl (the directories

are also on the S-Series CD-ROM). If you did not get the entire .zip file, please contact your Force10 account team.

•The ssh directory has example RSA1, RSA2 and DSA keys and a shell script called “generate-keys.sh” that can

be used to generate your own SSH keys.

•The ssl directory has example certificates and a shell script called “generate-pem.sh” that can be used to generate

your own SSL certificates.

The scripts provided use OpenSSH (http://www.openssh.org/) and OpenSSL (http://www.openssl.org/) for key and

certificate generation. Other free and commercial tools exist that can provide the same functionality and you can use

them if you like.

For additional options and commands related to the Telnet, SSH and HTTP/HTTPS features, please consult the

SFTOS manuals.

Enabling SSH

1. Generate the SSH keys using the script in the ssh directory, or copy the example keys (which end in .key) to your

TFTP server.

2. Copy the keys to NVRAM with TFTP as follows from this example, using the IP address of your TFTP server. For

SSHv1, copy the RSA1 key. For SSHv2, copy the RSA1, RSA2, and DSA keys, as shown below.

SFTOS #copy tftp://192.168.0.10/rsa1.key nvram:sshkey-rsa1

Mode........................................... TFTP

3. Enable the SSH server with this command.

SFTOS Version <= 2.2.1 SFTOS Version >= 2.3.1

(SFTOS) #ip ssh server enable

SFTOS (Config)#ip ssh server enable

To verify that the server has started, use this command to show the SSH server status and check the log file for

the following messages.

S-Series Secure Management

Using an SSH client, connect to the switch and login to verify that the SSH server is working.

4. Once you have verified that you can connect to the switch with an SSH client, the Telnet server can be disabled

with this command for additional security, if it was enabled. The Telnet server is disabled by default.

SFTOS Version <= 2.2.1 SFTOS Version >= 2.3.1

(SFTOS) #no ip telnet server enable

SFTOS (Config)#no ip telnet server enable

Enabling SSL/HTTPS

1. Generate the SSL certificates using the script in the ssl directory, or copy the example certificates (which end in

.pem) to your TFTP server.

2. Copy the certificates to NVRAM with TFTP as follows from this example, using the IP address of your TFTP

server.

SFTOS #copy tftp://192.168.0.10/dh512.pem nvram:sslpem-dhweak

3. Enable the HTTPS server with this command.

SFTOS Version <= 2.2.1 SFTOS Version >= 2.3.1

(SFTOS) #ip http secure-server

SFTOS (Config)#ip http secure-server enable

To verify that the server has started, use this command to show the HTTPS server status and check the log file for

the following messages.

SFTOS #show ip http

Java Mode: Disabled

HTTP Mode (Unsecure): Disabled

HTTP Mode (Secure): Enabled

Secure Port: 443

Secure Protocol Level(s): TLS1 SSL3

SFTOS #show logging buffered

JAN 01 01:16:19 192.168.0.34-1 UNKN[209189968]: sslt_util.c(321) 39 %% SSLT: Successfully

loaded all required SSL PEM files

Using a web browser, connect to the switch using an https:// URL and login to verify that the SSL server is working.

The padlock icon on your browser should indicate an encrypted connection.

If you used the example certificates, your browser will display a warning that it cannot verify the authenticity of the

certificate. This is because the example certificates have not been certified by a Certification Authority. When

certificates are acquired from a Certification Authority and loaded on the switch this warning will not occur.

4. Once you have verified that you can connect to the switch with a web browser, the HTTP server can be disabled

with this command for additional security if it was enabled previously. The HTTP server is disabled by default.

SFTOS Version <= 2.2.1 SFTOS Version >= 2.3.1

(SFTOS) #no ip http server

SFTOS (Config)#no ip http server enable
