FTP check if file exists and log it
Hi,

I need to create a script that checks if a file exists on an offsite server
which only has ftp enabled. I was originally going to use perls Net::FTP
class but the client does not have perl installed nor wants it.

So, I have to use a shell script which logs into the server, then
checks if different files exist in multiple directories.

Basically, all I need to do is check if the file exists in these directories
but redirect output to a log file which I could bring back to my main
server for further processing.

Here's what I have so far:


FtpUser="username"
FtpPswd="mypassword"
HostName="hostname"
FTPFile1="/u/backups/remotefile1"
FTPFile2="/u/backups/remotefile2"


( echo "user ${FtpUser} ${FtpPswd}
ls $FTPFile1
ls $FTPFile2
bye" ) | ftp -n ${HostName}

1. How can i capture the output of ls to a file either on the remote or
current server? and (this script will be placed in root's crontab)

2. Can I place the FTPFile{n} variable assignments into another file,
and use a while statement to read the lines 1 by 1 ... without having
to close the connection each time?

Hope I've explained this clearly.

Thank you!
G

Stupid me ... I figured i could just redirect the ftp output to
the local machine at the end of my ftp command.

But, can anyone help me with my 2nd question?

Thanks!

ftpconfig

ftpconfig(1M)						  System Administration Commands					     ftpconfig(1M)

NAME

       ftpconfig - set up anonymous FTP

SYNOPSIS

       ftpconfig [ftpdir]

       ftpconfig -d ftpdir

DESCRIPTION

       The ftpconfig script is executed by the super user to set up anonymous FTP. Anonymous FTP allows users to remotely log on to the FTP server
       by specifying the user name  ftp or anonymous and the user's email  address as password. The anonymous users  are  logged  on  to  the  FTP
       Server  and  given  access to a restricted file area with its own file system root. See chroot(2). The FTP area has  its own minimal system
       files.

       This command will copy and set up all the components needed to operate an anonymous FTP server, including creating the  ftp  user  account,
       creating  device  nodes,  copying  /usr/lib files, and copying timezone data.  The passwd and group files set up have been stripped down to
       prevent malicious users from finding login names on the server.	The anonymous file area will be placed	under  ftpdir.	If  the  ftp  user
       account already exists, then the current FTP area is used, and the system files in it are updated. All other files are left untouched. This
       command should be run to update the anonymous FTP area's configuration whenever a system patch is installed, or the system is upgraded.

OPTIONS

       -d	Create a new or update an existing ftpdir without creating or updating the ftp user account. Use this option when  creating  guest
		FTP user accounts.

OPERANDS

       The following operands are supported:

       ftpdir	The absolute pathname of the directory under which the anonymous FTP area is set up.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion

       1	Improper usage of the command

       2	Command failed
