Server Commands

session-escape-string

A configurable string that allows access to a port to view the multisession screen options, allowing the various options while accessing the particular port on the IOLAN. You can specify control (unprintable) codes by putting the decimal value in angle brackets < > (for example, ESC-bis <027>b). The default value is Ctrl-z s (<026>s in decimal).

 

retry

 

The number of times the IOLAN will retry to transmit a TPFT packet to/from a host

 

when no response is received. Enter a value between 0 and 5. The default is 5. A value

 

of 0 (zero) means that the IOLAN will not attempt a retry should TFTP fail.

 

timeout

 

The time, in seconds, that the IOLAN will wait for a successful transmit or receipt of

 

TFTP packets before retrying a TFTP transfer. Enter a value between 3 and 10. The

 

default is 3 seconds.

 

ssl-passphrase

 

This is the SSL/TLS passphrase used to generate an encrypted RSA/DSA private key.

 

This private key and passphrase are required for both HTTPS and SSL/TLS

 

connections, unless an unencrpyted private key was generated, then the SSL passphrase

 

is not required. Make sure that you download the SSL private key and certificate if you

 

are using the secure HTTP option (HTTPS) or SSL/TLS. If both RSA and DSA private

 

keys are downloaded to the IOLAN, they need to be generated using the same SSL

 

passphrase for both to work.

Set SSL Server

 

Description

Sets the default SSL/TLS parameters for the server.

User Level

Admin

Syntax

set ssl server [version anytslv1sslv3] [type clientserver]

 

[verify-peer onoff]

 

[validation-criteria

 

country <code>state-province <text>locality <text>

 

organisation <text>organisation-unit <text>

 

common-name <text>email <email_addr>]

Options

version

Specify whether you want to use:

zAny—The IOLAN will try a TLSv1 connection first. If that fails, it will try an SSLv3 connection. If that fails, it will try an SSLv2 connection.

zTLSv1—The connection will use only TLSv1.

zSSLv3—The connection will use only SSLv3.

The default is Any.

type

Specify whether the IOLAN will act as an SSL/TLS client or server. The default is

Client. verify-peer

Enable this option when you want the Validation Criteria to match the Peer Certificate for authentication to pass. If you enable this option, you need to download an SSL/TLS certificate authority (CA) list file to the IOLAN.

SDS, MDC specifications

Perle Systems is a leading provider of connectivity solutions, renowned for its robustness and reliability in networking hardware. Among its expansive product offerings, the MDC (Multiport Device Converter) and SDS (Serial Device Server) stand out as pivotal solutions for industries requiring seamless data communication and device management.

The Perle MDC serves as a powerful multi-port device converter, providing the ability to connect multiple serial devices to a computer network without needing a separate connection for each device. This is particularly useful in environments with limited computing resources or high device density, such as railways, manufacturing plants, or remote field operations. It is designed to convert serial communication, which is commonly used in legacy devices, into Ethernet/IP or TCP/IP protocols, ensuring that older devices can integrate into modern networks.

Main features of the MDC include its robust design for industrial environments, support for a variety of serial protocols, and multiple device connections. It supports data rates of up to 115200 bps and provides easy monitoring and configuration via a web-based interface. Additionally, the MDC incorporates advanced security features including SSL and SSH encryption, ensuring data integrity and protection against unauthorized access.

On the other hand, the Perle SDS model exemplifies advanced serial device hosting capabilities, allowing users to connect Ethernet networks to serial devices. It acts as a bridge, enabling remote devices to be configured and managed over IP networks. The SDS series is known for its versatility, supporting a range of serial communication protocols, including RS-232, RS-422, and RS-485, making it suitable for various applications such as point-of-sale systems, industrial automation, and remote monitoring.

The SDS boasts several characteristics that enhance its functionality, such as automatic device discovery, real-time monitoring, and local or cloud-based management options. Its feature set also includes traffic management capabilities, allowing the optimization of device communication by controlling the flow of data, which is critical for applications requiring high reliability and low latency.

Both the MDC and SDS benefit from a strong emphasis on ease of deployment and management. They support a range of network topologies, facilitating seamless integration into existing infrastructures. Furthermore, these devices are backed by Perle Systems' reputation for customer support and a commitment to ongoing innovation, ensuring that organizations can rely on these solutions for future growth and technological advancement.
