Hi,<br />
<br />
here is a script using &quot;telnet&quot; I once wrote and which several EE askers found useful.<br />
It can test any given port.<br />
Customize <i>PORT, HOST</i> and <i>MAILTO</i> below as desired.<br />
<br />
#!/bin/sh<br />
<i>PORT=23<br />
HOST=hostname<br />
MAILTO=&quot;aixtutorial@domain<wbr />.tld&quot;</i><br />
<br />
CHECKFILE=/tmp/sshchk.$$<br />
SLEEPTIME=2<br />
<br />
( telnet $HOST $PORT 2&gt;&amp;1 ) &gt;&nbsp;$CHECKFILE &amp;<br />
JOB=$!<br />
&nbsp; &nbsp;sleep $SLEEPTIME<br />
&nbsp; &nbsp;kill $JOB 2&gt;/dev/null<br />
<br />
if grep -q &quot;Connected to&quot; $CHECKFILE ; then<br />
&nbsp; &nbsp;:<br />
&nbsp; else<br />
&nbsp; &nbsp;mailx -s &quot;Port $PORT on server $HOST is down!&quot; $MAILTO &lt;&nbsp;$CHECKFILE<br />
fi<br />
rm $CHECKFILE 2&gt;/dev/null<br />
exit<br />

Hi,

here is a script using "telnet" I once wrote and which several EE askers found useful.
It can test any given port.
Customize PORT, HOST and MAILTO below as desired.

#!/bin/sh
PORT=23
HOST=hostname
MAILTO="aixtutorial@domain.tld"

CHECKFILE=/tmp/sshchk.$$
SLEEPTIME=2

( telnet $HOST $PORT 2>&1 ) > $CHECKFILE &
JOB=$!
   sleep $SLEEPTIME
   kill $JOB 2>/dev/null

if grep -q "Connected to" $CHECKFILE ; then
   :
  else
   mailx -s "Port $PORT on server $HOST is down!" $MAILTO < $CHECKFILE
fi
rm $CHECKFILE 2>/dev/null
exit

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
