FTP Error trapping

Humphrey_1 — Tue, 28 Jun 2005 09:46:04 GMT

I would like to trap all FTP error messages particularly when the network drops i.e. files are not transferred their entirety.

filedir=/informatica/7.1/fileshare/SrcFiles
ftpLogDir=/informatica/7.1/fileshare/Scripts/ftplogs
/usr/bin/ftp -n -v $HOST <&1 ${ftpLogDir}/ftp.log
quote user $USER
quote pass $PASSWD
ascii
cd $DIR
prompt
get $FILE ${filedir}/$FILE
bye
EOA

Is there a better way of trapping errors besides scanning the log files for error codes
?

Humphrey,
you could look at using the PERL::FTP module.
Also look at the man ftpd for a better breakdown of the ftp error codes.
Quick way to check successful transfer would be checksum the file before sending and then compare against checksum with rsh.

By far, the easiest method is Perl's Net::FTP module. You get error checking for free. The attached script will make it very easy for you and will return a meaning error code to the shell. If 0 status is returned, all is well. You can specify the login, password, optional account, directory, binary or ASCII, and the file(s) on the command line and all you need to do is look at the status.

It will also use .netrc if available so that the password does not have to be specified.

Ooops, I should have added invoke as ftpget.pl -u for full usage. This script will even work on Windows if one the the freely available Perls is installed.
