Appendix C: Using FTP

This appendix provides information on using ﬁle transfer protocol (FTP) with the Ethernet interface unit (EIU). FTP is an internationally accepted protocol for exchanging ﬁles between computing devices. Exchanged ﬁles can be in many formats. Further, computing devices can be hosts with different and even incompatible ﬁle systems.

CAUTION

Possible loss of network security

Using the Ethernet interface unit (EIU) and a telnet or file transfer protocol (FTP) session to establish a maintenance and administration position (MAP) session can introduce a security risk to both the DMS node and its subtending network.

When establishing and operating a MAP session in this way, there is limited security for clear text (user identification and passwords) and for Internet Protocol (IP) addresses for screening. This limited security makes an open local area network (LAN) vulnerable to entry by unauthorized persons.

Nortel recommends that the operating company, as a minimal precaution, integrate intermediate security servers with encryption to avoid unauthorized access to the switch. For alternative approaches, contact your Nortel representative to discuss state-of-the-art secure OA&M data communications equipment products.

By using the EIU, telnet, and FTP software, the operating company assumes any and all risks associated with the implementation and use of this hardware and software.
