A script like this set up on ServerA should do the trick.

Code:

#!/bin/bash
date=`/bin/date +%Y%m%d%H%M%S`

email_to="unixforum@localhost"
email_subject="Something went wrong"
email_body="Uh-oh"

server="localhost"

if ! /usr/bin/ssh "$server" "/usr/bin/touch /mnt/testfile.$date" >/dev/null 2>/dev/null
then
        echo "$email_body" | /usr/bin/mail -s "$email_subject" "$email_to"
        exit 1
fi

exit 0

The 'date' variable at the top just creates a string via the 'date' command that consists of the year, month, date, hour, minute and second all run together. I went with this since you didn't specify any particular format, but this should do for most purposes (if the script only runs at most once per second, anyway).

The next three variables define the recipient, subject and body of the e-mail message. You can customise those all you like.

Finally, the variable 'server' defines the remote server that the 'ssh' command will use to connect to. You'll want to change this to the details of whatever ServerB is.

The basic idea of the script is that it connects to the remote server, and if the 'touch' command (or the 'ssh' command itself) returns a non-successful exit value for any reaason, it then proceeds to send the e-mail.

Here's an example session of it running, in a situation where the touch command at the remote end (which is really just 'localhost' in my test case) fails.

Code:

$ whoami
unixforum
$ ./script.sh 
$ mail
"/var/mail/unixforum": 1 message 1 new
>N   1 unixforum@localhost Mon Feb 20 15:17  15/654   Something went wrong
? 1
<e-mail headers appear here, redacted>

Uh-oh
? d 1
? q
Held 0 messages in /var/mail/unixforum
$

Hope this helps.

Yes thank you!!! script worked like a charm!!

pollrcvd

POLLRCVD(8C)															      POLLRCVD(8C)

NAME

       pollrcvd - HylaFAX script for delivering facsimile received by polling

SYNOPSIS

       /var/spool/fax/bin/pollrcvd mailaddr faxfile devid commid error-msg

DESCRIPTION

       bin/pollrcvd  is the command script invoked by the HylaFAX server whenever a facsimile is received as a result of a polling operation.  The
       default script uses electronic mail to deliver the facsimile to the user that submitted the poll request, and can be controlled by  editing
       the etc/PollDispatch shell script in the spooling area that is sourced by pollrcvd when it runs.  The arguments are:

       mailaddr  the electronic mail address of the user that submitted the poll request.

       faxfile	 the pathname of the received TIFF file relative to the root of the spooling hierarchy.

       commid	 The communication identifier associated with the call (used to include a transcript when an error occurs).

       devid	 the modem device on which the document was received.

       error-msg an error message that is non-null if an error was encountered during the receive operation.

NOTES

       The default script delivers facsimile as PostScript wrapped in MIME.

FILES

       /var/spool/fax	    spooling area
       /usr/sbin/faxinfo    for printing information about the facsimile
       /usr/bin/fax2ps	    for converting TIFF to PostScript
       /usr/sbin/sendmail   for delivering mail
