Disconnecting an Active telnet or rlogin Session

Modifications to the telnet and rlogin features of the CoreBuilder 6000 system allow you to preempt users by forcing a disconnection. This administrative feature requires you to use the system Administer-level password at the Administration Console.

The rlogin usage is identical to the telnet usage. Substitute rlogin wherever you see telnet.

Implementation. When you attempt to use the telnet command to enter a system that is being used by another telnet connection, the system displays:

Sorry, this system is engaged by another telnet session.

Host IP address: xxx.xxx.xxx.xxx

Logout the other telnet session? (Y/N) y

Enter Password: administer-level-password

The first telnet session is disconnected and the system displays:

LOGGING OUT the other telnet session.

You can then connect in the usual manner.

If you enter an incorrect password, the system displays:

Incorrect password. Disconnecting.

The system automatically disconnects after it receives three incorrect attempts at the administer-level password.

If you respond n to the request to disconnect, your session disconnects and the original connection remains established. The system displays:

Disconnecting

CAUTION: When you preempt a telnet or rlogin session in this manner, the current session user receives no notice that the session will be disconnected.

If you enter y at the Logout the other telnet session? prompt and it is not accepted, it is probably because of the telnet configuration on the UNIX host. To force the system to accept your response to the prompt, follow these steps:

1Escape to the telnet session by pressing Ctrl+}

6000 specifications

The 3Com 6000 series, launched in the late 1990s, was a significant advancement in networking technology, designed to meet the growing demands of enterprise-level networking. This series provided powerful solutions for businesses seeking reliable, efficient, and scalable networking capabilities.

At its core, the 3Com 6000 series featured a modular design, allowing companies to customize their networks according to specific needs. This flexibility meant that organizations could add or replace components as their networking requirements evolved, ensuring investment protection and a tailored approach to connectivity. The ability to scale was particularly important for businesses that anticipated growth or change in operational demands.

One of the standout features of the 3Com 6000 was its advanced switching capabilities. The series employed high-performance switching technologies that supported various protocols, including Fast Ethernet and Gigabit Ethernet. This versatility made it suitable for diverse environments, from small offices to large corporate settings. The 3Com 6000 switches were engineered to deliver high throughput and low latency, crucial for applications requiring real-time data transfer.

The series also supported a range of network management tools, enhancing operational efficiency. With SNMP (Simple Network Management Protocol) support, network administrators could easily monitor and manage network performance, troubleshoot issues, and configure devices from a centralized location. This capability significantly streamlined network operations, reducing downtime and optimizing resource allocation.

Security was another significant concern addressed by the 3Com 6000. The series incorporated robust security features, including access control lists (ACLs) and VLAN (Virtual Local Area Network) support. These features allowed network administrators to segment traffic and enforce security policies, protecting sensitive data and ensuring compliance with organizational standards.

Moreover, the 3Com 6000 series was designed with energy efficiency in mind, reflecting a growing awareness of the environmental impact of IT infrastructure. By implementing power-saving features, the series helped organizations reduce their overall energy consumption while maintaining optimal network performance.

In summary, the 3Com 6000 series stood out for its modularity, advanced switching capabilities, extensive management tools, strong security features, and energy efficiency. It represented a forward-thinking solution for enterprises aiming to build robust network infrastructures capable of supporting a wide range of applications and services. As organizations increasingly relied on networked systems, the 3Com 6000 played a crucial role in shaping the landscape of enterprise networking.
