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.
