1.2.4 Accessing through SSH

Telnet is lack of security authentication and it transports messages through Transmission
Control Protocol (TCP) which exists with big potential security hazard. Telnet service may
cause hostile attacks, such as Deny of Service (DoS), host IP spoofing, and routing spoofing.
The traditional Telnet and File Transfer Protocol (FTP) transmit password and data in plain
text, which cannot satisfy users' security demands. SSHv2 is a network security protocol,
which can effectively prevent the disclosure of information in remote management through
data encryption, and provides greater security for remote login and other network services in
network environment.
SSHv2 allows data to be exchanged through TCP and it establishes a secure channel over TCP.
Besides, SSHv2 supports other service ports besides standard port 22, avoiding illegal attacks
from the network.
Before accessing the ISCOM2600G-HI series switch through SSHv2, you must log in to the
ISCOM2600G-HI series switch through the Console interface and start SSH service.
Default configurations for accessing the ISCOM2600G-HI series switch through SSHv2 are
as below.
SSH server status
Local SSH key pair length
Key renegotiation period
SSH authentication method
Telnet Client: when you connect to the ISCOM2600G-HI series switch through the PC
terminal emulation program or Telnet client program on a PC, then telnet other
ISCOM2600G-HI series switch and configure/manage them. As shown in Figure 1-4,
Switch A not only acts as Telnet server but also provides Telnet client service.
