Linux Fieldbus Coupler
4.5 Ethernet Interface Services
The Linux fieldbus coupler provides several server/client services for the
Ethernet interface (condition upon delivery). The following gives a short
overview:
• Telnet server
Network participants can connect to the Linux coupler console via a Telnet
client.
• FTP server
Network participants can access the Linux coupler file system via an FTP
client.
• FTP client
The FTP client of the Linux fieldbus coupler can exchange data with
remote FTP servers.
• Web server
Network participants can call information on the Linux coupler settings via
a web browser.
• SNTP client
The installed MSNTP client can retrieve the exact time of a remote SNTP
server via the network.
• NFS client
The Linux fieldbus coupler incorporates an NFS client which can link
shared network drives of NFS servers.
• TFTP client
The TFTP client is only implemented in the boot loader (U-Boot) and
allows update of the Linux kernel, the root file system or the boot loader
(U-Boot) itself. After Linux kernel start-up, the client is no longer
available.
4.5.1 Telnet Server
The telnet login service is started (condition upon delivery). The inetd.conf file
has a corresponding entry. The telnet daemon is started via Ethernet if
requested. A new Linux console is created.
The Linux console login and the login via the serial interface run
simultaneously (see chapter 4.3).
