web/ftp monitoring program?

[Henrik Goldman]

Hi all

Does any of you know of a program(s) which can check for changes in web and
ftp sites?
It should be able to look for any diffrences in a directory on a ftp and
report it via email.
With web it should also compare it with a reference page for any
differences.
Maybe a shell script would do?

Thanks in advance,
Henrik Goldman

HI,

It really depends on what kind of change do you want to track.

1) the last modified value of the file (it may not have changed, but
been touched)

2) real change of the file (you then would go by keeping a checksum of
each file)

3) give you the actual difference

I think the 1st one s easy to write, 2nd should be part of some security
package like cops (I think), third impliesthat you keep a secure copy of
your file system for the sake of comparison.

Hi

I'm sorry I wasn't specific enough.

I found this program for Windows which actually can do what I need:

http://www.boutell.com/morning/

What it does is that it makes a database and keep info on a given url (ftp
or web). Then you can do hourly update to see if anything on the page has
changed. It don't need byte specific changes or checksum for files just
updates like new or modified files or changed webpages.

Even though this program actually fills my needs it would still be nice to
find such for my favorate OS.
