Running ETFTP
=============

   The protocol contains two parts:

      etftp - client
      etftpd - server daemon

   The server part should be started as a daemon by the inetd.  Add
following line to the /etc/inetd.conf

      etftp   dgram   udp     wait    root    /usr/sbin/tcpd  in.etftpd

Also add the following line to /etc/services

      etftpd         1818/udp           # ETFTP daemon

To manually start the server, type `etftpd -i'.  Other parameters are

      t - trace mode (creates a log file in current directory)
      v - verbose mode (creates a debug file in /var/log/)
      b n - set block size to n bytes per block

   To start the client program, type `etftp'. All parameters can be set
inside the program.  At the command line, type `?' for a complete list
of etftp specific parameters.  The program also takes some parameters when
starting the program. These are the following

      [host] - host name
      t - trace mode (creates a log file in current directory)
      v - verbose mode (writes debug info to stdout)
      H - hash mode. Prints a `#' for each packet received.
      f s - read commands from a batch file named s


Testing ETFTP
=============

We normally test etftp by using a batch file for the client. Assuming
that the etftp server is started on one host as

      ./etftpd -ivb 512  -l 1717

we start the etftp client on an other host using the batchfile.sample as

      ./etftp -f batchfile.sample


Here's an example of the batchfile.sample:

connect cassandra 1717
autoadapt on
baudrate 970
binary
blocksize 256
bufferblock 40
burstsize 10
hash off
radiodelay 1
verbose on
get /etc/services ./services.cassandra

End example batchfile.sample.
