SSHD
Enabling SSHd allows users to access the Linux OS of their router with an SSH client
SSH TCP Forwarding: enable or disable to support the TCP forwarding (SSH tunnels)
Password Login: allows login with the router password (username is admin)
Port: port number for SSHd (default is 22)
Authorized Keys: here users paste their public keys to enable key-based login (more secure than
a simple password)
System log
Enable Syslogd to capture system messages. By default, they will be collected in the local file
/var/log/messages. To send them to another system, enter the IP address of a remote syslog
server.
Syslog Out Mode: three logging modes:
Net: the log information output to a syslog server
Console: the log information output to console port
Web: the log information is available via the router webpage under “Administration” menu
Remote Server: if choose net mode, users should input a syslog server’s IP Address
Telnet
Telnet: enable a telnet server to connect to the router with telnet. The username is admin and
the password is the router's password.
