script to login to ftp and check

yuva_mca — Tue, 29 Nov 2005 01:45:57 GMT

I need the shell script which suppose to check the ftp transation.
Like the script has to login to the ftp site with corresponding username and password. If ftp have any issues while executing the script, script suppose to throw the message with corresponding issue(eg : problem with port or problem server or etc).

Thanks
Yuva

You can try as,

ftp -i -n <<-EOF
user
ls
mget
!ls
EOF

You can check script results as echo ${?} after EOF statement.

ftp -i -n <<-EOF
user
ls
mget
!ls
EOF 1>/tmp/output.log 2>/tmp/error.log
if [[ ${?} -eq 0 ]]
then
echo "FTP: Success $(date)"
else
echo "FTP: Failure $(date)"
fi

You can view /tmp/output.log for STDOUT messages and /tmp/error.log for STDERR informations like problem with port or connectivity problem.

PS: Change the commands you want to execute there.

I think that echo $? wont work to identify if there where a problem with the transacion, for example:

# echo bye |ftp -i localhost
ftp: connect: Connection refused
# echo $?
0

You should use the log file created as described above and find for a "transfer ok" message. The message vary depending of the ftp server.

For example, for vsftpd:

227 Entering Passive Mode (127,0,0,1,75,234)
150 Opening BINARY mode data connection for file (0 bytes).
226 File send OK.

So, the verification should be something like:

CORRECT=`grep -w OK $LOGFILE |wc -l`

if [ $CORRECT = 1 ]; then
echo "Transfer correct"
else
echo "There was a problem with the file transfer, check $LOGFILE"
fi

#!/bin/bash
ftp -i -n 192.0.0.1 <<-EOF
user anonymous anonymous
ls
EOF

This is the script I have used to test. But it is getting hang. so I have killed the process. I hope as per the script it won't take the plain password. Some one please write the script and test it and let me know. It would be great help for me.

You last command should be "bye" to end the ftp transaction.

Remove the - in <<-EOF, should be <
Ensure that the last EOF is not indented.

#!/bin/bash
ftp -i -n 192.0.0.1 <user anonymous anonymous
ls
bye
EOF

#!/bin/bash
ftp<<**
open 192.1.1.1
anonymous
ls
**

The above script is working. But It is asking the password while executing the script. When I mentioned the password in the script is not taking.It seems we need to give the password at the time of executing the script.

Please check the same and let me know. I donn't want to enter the password manually. we need to mention the password in the script and it suppose to take the password while executing the script. Please suggest the same.

Thanks

Use like,

ftp -i -n 192.1.1.1<<**
user anonymous
ls
**

It will take. If you use open then it will prompt for username and password.

Use the ftp script in my prev. threads.
