Ethernet Interface Services; Telnet Server - WAGO 750 Series Manual

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

• FTP server
• FTP client
• Web server
• SNTP client
• NFS client
• TFTP client
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).
WAGO-I/O-SYSTEM 750
Linux Fieldbus Coupler
Network participants can connect to the Linux coupler console via a Telnet
client.
Network participants can access the Linux coupler file system via an FTP
client.
The FTP client of the Linux fieldbus coupler can exchange data with
remote FTP servers.
Network participants can call information on the Linux coupler settings via
a web browser.
The installed MSNTP client can retrieve the exact time of a remote SNTP
server via the network.
The Linux fieldbus coupler incorporates an NFS client which can link
shared network drives of NFS servers.
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.
