The FTPDCMDS subdirectory contains commands to use from the web

browser.

• Click EXITME.BIN to execute a SITE EXIT command.

• Click REBOOTME.BIN to execute SITE BOOT command.

• Use the GET command on these files to have the FTP Server execute

these commands.

• Security:

A customer configurable access control list may be installed on the

CN2B Computer. This list will allow customers to restrict access via

the FTP Server to users they wish and is in addition to default Inter-

mec accounts that are disabled using the -F0 option at runtime.

The access control list is named FTPDCE.TXT and is placed in the

same directory on the CN2B Computer as the FTPDCE.EXE server.

The FTP Server encrypts this file to keep the information safe from

unauthorized users. This file is encrypted when the FTP Server is

started so a file that is placed onto the CN2B Computer after the FTP

Server starts will require a restart of the FTP Server to take effect.

The format of the FTPDCE.TXT is as follows:

FTPDCE:user1!passwd1<cr><lf>user2!passwd2<cr><lf>user3!pas

swd3<cr><lf>...

Note: The user accounts and passwords are case-sensitive. Once the access

control list is encrypted on the CN2B Computer, the FTP Server hides this

file from users. Once an access control list is installed on the CN2B Com-

puter, a new one is not accepted by the FTP Server until the previous one is

removed. Encrypted access control lists are not portable between CN2B

Computers.

Stopping the FTP Server from Your Application

To allow application programmers the ability to programmatically shut

down the FTP Server, the FTP Server periodically tests to see if a named

event is signaled. The name for this event is “ITC_IFTP_STOP” (no

quotes).

For examples on how to use events, consult the Microsoft Developer Net-

work Library at www.msdn.com. The MSDN Library is an essential

resource for developers using Microsoft tools, products, and technologies.

It contains a bounty of technical programming information, including

sample code, documentation, technical articles, and reference guides.
