A colleague of mine, Mahlon Anderson, wanted to revisit the FTP Using a Shell Script post.

Here is what he had to say...

Here is a creative way to put an FTP command on a single line. Why one line? The short story is I needed to do an ftp in a crontab without calling another script.

Three things to note:

1) I have only tested this with Solaris 8.
2) This works in the one true shell, Bourne shell.
3) If you have a "$" in your password, it might cause you problems.

echo “quote user \nquote pass \ncd \nbin\nlcd \nput ” | ftp –n

Use this in a Perl script. (I didn’t have access to the CPAN FTP module)

# vi myftp.pl

#!/usr/bin/perl

$USER = “esoft”;
$PASSWORD=”myftp125”;
$REMOTE=”esoft”;
$DIR=”/jpg_dir;
$FILE=”esoft.jpg”;
$echo = ‘echo “quote user ‘ . $USER. ‘\nquote pass ‘ . $PASSWORD .’\nbin\nlcd ‘ . $DIR . ‘\nmput $FILE\n”’;
@status = ‘$echo| ftp –nv $REMOTE‘;
print @status;
:wq!

The FTP module is for doing FTP directly with Perl...basically system calls to the C library directly. With the right modules, you can do all that from Perl without having to resort to the back quotes.

Run via CLI

# ./myftp.pl

We recently purchased a new network application/appliance.

As part of my normal practice, I wanted to configure the
appliance to duplicate its logs to our centralized syslog server.
With standard syslogd, you add one line to your configuration
file (syslog.conf) and restart the daemon.

But this appliance uses syslog-ng, an enhanced and more
powerful syslog application.

The syslog-ng configuration file (syslog-ng.conf) includes
four main components: source, filter, destination, and log.

1. source (required) - This tells syslog-ng the source of
the log data. This could be a network port, streams,
a file (/proc/kmsg).

2. filter (optional) - If you want to throw all your log
data into one file, you don't need a filter.

3. destination (required) - Syslog-ng needs to know what
to do with the data it reads from "source". Destination
can be a file, a remote server IP, a pipe, usertty, etc.

4. log (required) - This is the line that makes it all
happen by bringing the above items together.

This line basically says:
"look at all the logs coming from $source, pull
this $filter and save it in $destination."

NOTE: You can include multiple source, filter and
destination on this line.

For example:
I want to configure syslog-ng to send all logs to a
local file and to my Centralized Log Server (IP 1.2.3.4)

-----------------
# Solaris Configuration:

# SOURCE
# This source entry allows locally generated logs to be captured

source local { sun-streams("/dev/log" door("/etc/.syslog_door")); internal(); };

# FILTER (optional)
# I'm not defining any filter since I want everything.

# DESTINATION
# I want to send the logs via standard syslog udp port to IP# 1.2.3.4)
# and to a file locally, /var/log/everything.log.

destination logserver { udp("1.2.3.4"); };
destination localfile { file("/var/log/everything.log"); };

# LOG

log { source(local); destination(logserver); destination(localfile); };

---------------

After you edit your configuration file, you can verify the syntax using this command:

$ syslog-ng -s

If you don't have any errors, restart your syslog-ng daemon.
You should now be logging everything to the file /var/log/everything.log as well as to the remote log server.
