Présentation
CM4001 console servers enable system administrators, network managers and support help desks to affordably monitor and control the devices, computers and networks in the remote sites under their care.
The CM4001 provides secure in-band and out-of-band access to the serial consoles of the UNIX, Windows, Sun and Linux computers and the networking infrastructure (switches, firewalls etc) at these sites. It can also provide remote monitoring and control of appliances such PBXs, building security, telecommunications equipment and power distribution units.
By locating a CM4001 in each remote site, secure central control and management becomes affordable at even the smallest edge location (ISP POPs, retail POS, gaming sites etc).
Flexible Robust and Secure Opengear’s console servers provide a simple and secure solution for accessing, monitoring, and controlling distributed networks of appliances. The CM4001 provides secure access for remote configuration, monitoring and disaster recovery ensuring availability at critical times.
As would be expected with a quality console server, all CM4001 connections are secure, with encrypted access to remote systems using up to 128-bit AES encryption. The CM4001 console server at a remote site can be accessed in-band through the Internet or the enterprise IP network or out-of-band (OoB) through a dial-up modem PPP port or a However managing devices in highly distributed networks needs powerful yet flexible access control mechanisms. So the CM4001 offers a selection of access filtering, redirection and authentication facilities e.g. access can be restricted by IP address, password and account, and once a user is authenticated they can be further restricted to using nominated services and TCP/UDP ports on the specific devices they have been authorized to access. These facilities can be customized and the manager can easily copy scripts, binaries and configuration files directly to the CM4001. Opengear also provides a custom development kit (CDK) which allows changes even to be made to the software in CM4001 firmware image.
All in-band and out-of-band management activity is monitored and logged, and these logs can be archived off line. The CM4001 can also monitor the serial consoles for events or conditions that will trigger it to automatically send alerts via e-mail, SNMP or NAGIOS; a feature which can mitigate system and network disasters.
Out-of-band network console access
The CM4001 also provides secure out-of-band management access to devices on the local LAN at remote sites. Increasingly managed devices have an Ethernet network port (rather than a serial port) dedicated as their management console. With the CM4001 the administrator can remotely access these network console ports. They can also dial in to the CM4001 and have secure remote access to all the TCP/UDP ports on all networked devices at the site. The CM4001 supports SSH tunneling which provides this secure remote access to computers and devices using tools like RDP, VNC, HTTP, HTTPS, SSH,Telnet and X. The SDTConnector client software that is provided with each CM4001 further simplifies these connections.
The CM4001 can also monitor appliances on the local network at these remote sites and send alarms when trigger conditions occur. So remote administrators can use the one CM4001 console server to manage their computer systems and networked appliances using (text or graphical) serial or network consoles.
