Error handling for automated uploads in Ubuntu?

Question

Every day I need to upload automatically about 100 images with a total size of 4MB.

I've used ncfttput and FTP via command line, but sometimes the upload of one image gets stuck with a Connecting to port message, and so it stops the FTP-upload of the others.

I'm currently using this script:

#!/bin/bash
cd /home/giacomo/WRF/DOMAINS/puglia/postprd
ftp -i -n -v <<EOF
open "server"
user "username" "password"
binary
cd /www.example.org/wrf
mput 2mTemp*.gif
quit
EOF

sleep 10

ftp -i -n -v <<EOF
open "server"
user "username" "password"
binary
cd /www.example.org/wrf
mput 850mbRH*.gif
quit
EOF
etc...

How could I set a timeout with a consequential retry? Or is there a non-command line method to manage all of this automatically (sync my local folder with my remote folder and take care of any errors)?

I have resolved by using the FTP passive mode. Here is the new FTP command:

#!/bin/bash
cd /home/giacomo/WRF/DOMAINS/puglia/postprd
ftp -i -n -v <<EOF
open "server"
user "username" "password"
binary
passive
cd /www.example.org/wrf
mput 2mTemp*.gif
quit
EOF

sleep 10

ftp -i -n -v <<EOF
open "server"
user "username" "password"
binary
passive
cd /www.example.org/wrf
mput 850mbRH*.gif
quit
EOF
etc...
