Checking if network is up before you try to ftp will not help if the network goes while a transfer is happening.
I don't know how long a ftp-client usually "hangs" until it receives a timeout and if it really spits out a return code >1 in that case (it should). Different ftp-clients might have different options for this.
ftp is not encrypted and unsecure - maybe switch to ssh/scp/sftp and set up public key authentication, if it is an option. You would also not have to write clear passwords in a file.
You can use helpful options with scp for example like:
see man scp.
You can script a lot of things around it to make it more waterproof for your problem case, but generally I'd say you should try to solve that network problem as priority and implement the ssh/scp/sftp protocol suite.
I have got a unix server ( AIX ) and 20 clients ( windows 2000 ) . I have to transfer a file through FTP from the server to each of 20 clients daily to check the network speed.
But each time I do ftp, I have to enter username and password and then transfer the file using "put <filename>". I... (2 Replies)

scp
SCP(1) BSD General Commands Manual SCP(1)NAME
scp -- secure copy (remote file copy program)
SYNOPSIS
scp [-346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-S program] [[user@]host1:]file1 ...
[[user@]host2:]file2
DESCRIPTION
scp copies files between hosts on a network. It uses ssh(1) for data transfer, and uses the same authentication and provides the same secu-
rity as ssh(1). scp will ask for passwords or passphrases if they are needed for authentication.
File names may contain a user and host specification to indicate that the file is to be copied to/from that host. Local file names can be
made explicit using absolute or relative pathnames to avoid scp treating file names containing ':' as host specifiers. Copies between two
remote hosts are also permitted.
The options are as follows:
-3 Copies between two remote hosts are transferred through the local host. Without this option the data is copied directly between the
two remote hosts. Note that this option disables the progress meter.
-4 Forces scp to use IPv4 addresses only.
-6 Forces scp to use IPv6 addresses only.
-B Selects batch mode (prevents asking for passwords or passphrases).
-C Compression enable. Passes the -C flag to ssh(1) to enable compression.
-c cipher
Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1).
-F ssh_config
Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1).
-i identity_file
Selects the file from which the identity (private key) for public key authentication is read. This option is directly passed to
ssh(1).
-l limit
Limits the used bandwidth, specified in Kbit/s.
-o ssh_option
Can be used to pass options to ssh in the format used in ssh_config(5). This is useful for specifying options for which there is no
separate scp command-line flag. For full details of the options listed below, and their possible values, see ssh_config(5).

-P port
Specifies the port to connect to on the remote host. Note that this option is written with a capital 'P', because -p is already
reserved for preserving the times and modes of the file.
-p Preserves modification times, access times, and modes from the original file.
-q Quiet mode: disables the progress meter as well as warning and diagnostic messages from ssh(1).
-r Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal.
-S program
Name of program to use for the encrypted connection. The program must understand ssh(1) options.
-v Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection,
authentication, and configuration problems.
EXIT STATUS
The scp utility exits 0 on success, and >0 if an error occurs.

scp is based on the rcp program in BSD source code from the Regents of the University of California.
