Problem with FTP script

Sean OB_1 — Mon, 16 Feb 2004 11:45:17 GMT

Hello. I'm writing a quick script to ftp a bunch of files to all of our servers. The script fails on login, however I can login fine manually executing the exact command sequence that is in the script. Any help is appreciated.

Here's the script.

for SERVER in `cat /tmp/servers`
do
echo "FTP to $SERVER"
sleep 1
ftp -in <<-EOF
open $SERVER
user
ascii
lcd /tmp
cd /tmp
put file1
put file2
chmod 700 /tmp/file2
bye
EOF
done

The nasty part is I don't know any way to check return codes.

Perhaps there is a non-visual junk character in the username or password?

The script looks good.

Would this work?

for SERVER in `cat /tmp/servers`
do
echo "FTP to $SERVER"
sleep 1
ftp -in <<-EOF
open $SERVER
user

ascii
lcd /tmp
cd /tmp
put file1
put file2
chmod 700 /tmp/file2
bye
EOF
done

based on the fact that if a user needs a password, the ftp server will prompt for it with something like

user blah needs a password:

Nope, no non display chars, retyped the line and all.

breaking the user line to

user

causes the script to pause and ask for my password. I can type in the same password in the script and it continues fine and sends the files.

Hi Sean,

I would try couple of checks.

1. Try with hardcoding the servername in side the ftp script. Take out the for loop.

2. Run it with -v and look at the session log. See if the password is really being passed.

I copied and pasted your script without the for loop and it is working just fine for me.

The username is being passwd, and it fails even outside of the for loop.

Here is the result:

root@cosmo0:/tmp-> ./ftp1

Hi,

Looks like it didn't like the password. Try with a simple password to test your ftp script.

Not all ftp servers are the same. When logging into a solaris ftp server, I got the same result as you... when logging into a linux ftp server your script worked just fine. I would use expect for this.

This is the guts of a script I use to send error messages to a central server :-

file=test.txt
ftplogfile=/tmp/ftplogfile.log

ipaddress=yourhostname

ftp -nv <>$ftplogfile 2>>$ftplogfile
open $ipaddress
user username password
ascii
cd /remote_directory
put $file remotefilename
site chmod 770 remotefilename
bye
EOF

You'll need to substitute yourhostname, username, password, remote_directory, remotefilename

Works every time. One thng to watch out for is sometimes indenting the lines between EOF's can upset ftp. I always left justify the block even inside a loop.

Regards,

Dave.

Run the FTP command with the -i option to disable interactive prompting. Your script with the ID and password on the same line should then work ok.

I don't like FTP for the very reason that it is so difficult to script. And if you do get a script to work, maintenance is difficult (as you've found out). I recommend that you use secure copy instead. This is secure and it scripts nicely: you can test for return codes, and your script doesn't have to have any passwords in it at all--always a security risk. Get and install secure copy (ssh) on all your systems. Its a PITA to configure, but once you get it done, maintenance is negligible.

OK, if nobody does it, here's a perl script with a lot of error catching and debugging

Also attached for formatted codeis not supported yet

#!/opt/perl/bin/perl

use strict;
use warnings;

use Net::FTP;

@ARGV = ("/tmp/servers");
while (<>) {
chomp;
my $ftp = Net::FTP->new ($_, Debug => 3) or
die "$_: cannot connect: ", $ftp->message;
$ftp->login ('user', 'password') or
die "$_: cannot logon: ", $ftp->message;
$ftp->ascii or
die "$_: cannot set ascii mode: ", $ftp->message;
chdir "/tmp" or die "/tmp: $!\n";
$ftp->cwd ("/tmp" or
die "$_: cannot chdir to /tmp: ", $ftp->message;
foreach my $file (qw( file1 file2 )) {
$ftp->put ($file) or
die "$_: cannot put $file: ", $ftp->message;
# I have no idea how to do chmod in Net::FTP
# chmod 700 /tmp/file2
$ftp->quit;
}

Some embarrasing typo's is what you get when you post half asleep and don't test.

#!/opt/perl/bin/perl

use strict;
use warnings;

use Net::FTP;

@ARGV = ("/tmp/servers");
while (<>) {
chomp;
my $ftp = Net::FTP->new ($_, Debug => 3);
$ftp or die "$_: cannot connect: $@";
$ftp->login ('user', 'password') or
die "$_: cannot logon: " . $ftp->message;
$ftp->ascii or
die "$_: cannot set ascii mode: " . $ftp->message;
chdir "/tmp" or die "/tmp: $!\n";
$ftp->cwd ("/tmp") or
die "$_: cannot chdir to /tmp: " . $ftp->message;
foreach my $file (qw( file1 file2 )) {
$ftp->put ($file) or
die "$_: cannot put $file: " . $ftp->message;
# I have no idea how to do chmod in Net::FTP
# chmod 700 /tmp/file2
$ftp->quit;
}

Should be better.

Enjoy, Have FUN! H.Merijn
