Znyx Networks bh5700 Connecting to the Switch Using Tftp, Tftpd Server Configuration, Snmp Agent

ftpd Server Configuration

The switch itself can also be configured to run an FTP server (ftpd). See the Linux Reference Guide for details of the ftpd command. You will need to add a user to the switch in order to connect via ftp from a remote host, since root is not allowed ftp access. See the earlier section in this chapter regarding how to add a user. The ftp daemon is started by default. If you wish to shutdown the ftp daemon, comment out the betaftpd line in /etc/init.d/rcS.

Connecting to the Switch Using TFTP

Trivial File Transfer Protocol or TFTP, is a very simple protocol used to transfer files. It is designed to be small and easy to implement. Therefore, it lacks most of the features of a regular FTP, like user authentication. You can use tftp to connect to any system running a TFTP server (tftp) including other OpenArchitect switches.

tftp <remote_host>

TFTPD Server Configuration

The TFTP server is started by inetd(8) using the configuration set up in /etc/inetd.conf. The use of tftp(1) does not require an account or password on the remote system. Due to the lack of authentication information, tftpd will allow only publicly readable files to be accessed. The default location of these files is /tftpboot.

SNMP Agent

Simple Network Management Protocol (SNMP) is the defacto standard for network management. An SNMP agent maintains a structure of data for a network device in a virtual information database, called a Management Information Base (MIB). A network management station is capable of accessing the MIB of the network device to monitor and configure the network device.

The OpenArchitect switch utilizes the NET-SNMP (formerly UCD-SNMP) agent core. Additional information on the agent can be found at: http://www.net-snmp.com. The OpenArchitect switch agent will respond to SNMPv1, SNMPv2, and SNMPv3 requests.

Protocols supported on the OpenArchitect switch by gated, such as RIP and OSPF communicate with SNMP agent via the SNMP Multiplexing (SMUX) protocol.

Supported MIBS

OpenArchitect includes MIB support as documented by each of the RFCs listed. The MIBs themselves are located on the switch in the /usr/share/snmp/mibs directory.
