Step 6: Create the System Key File

$ cat syscert.pem syskey.pem cacert.pem > sys.pem

6.5.3.10 Certificate and Key File Installation

After generating your root CA certificate and key file, you must install them on your
system. Use the

4.8.1.1: Certificates: Local

screen, and the

4.8.1.2: Certificates: Trusted

screen, to do this

6.5.4

RADIUS Support

Multinet4 supports remote user authentication by a RADIUS server.

Radius is an authentication, authorization, and accounting (AAA) protocol defined in RFC
2865 and RFC 2866.

Authentication

– A RADIUS server receives requests for connections and checks that the

username and password provided are authentic using a shared secret and one of two
authentication schemes.

Authorization

– After successful authentication the RADIUS authorizes the requesting user

to begin a session on the system.

Use the

4.8.6.1: RADIUS: Global Settings

screen, and the

4.8.6.2: RADIUS: Servers

screen, to

add RADIUS servers and to configure them.

6.5.5

Multinet4 Cipher Support

The following list specifies the type of cipher supported by Multinet4 for each security
purpose:

Signing/Authentication – RSA

Key Exchange – RSA

Cryptographic Hashing – SHA1, MD5

Encryption – DES, 3DES, RC4, AES

The Multinet4 supports the following standard cipher suites:

SSL_RSA_EXPORT_WITH_RC4_40_MD5

SSL_RSA_WITH_RC4_128_MD5

SSL_RSA_WITH_RC4_128_SHA

SSL_RSA_WITH_DES_CBC_SHA

SSL_RSA_WITH_3DES_EDE_CBC_SHA

TLS_RSA_EXPORT_WITH_RC4_40_MD5

TLS_RSA_WITH_RC4_128_MD5

TLS_RSA_WITH_RC4_128_SHA

TLS_RSA_WITH_DES_CBC_SHA
