snoop could do the trick.<br />
&quot;man snoop&quot;

$&gt;netstat -an<br />
will give you the state and more.

<div>
what type of ports? each port means one type of protocol. There are tools for some protocols that can be used to monitor.
</div>


<div>
You have a few answers here, but the real problem is that you haven't really told us what you need here. What kind of ports do you mean, and what kind of monitoring? &nbsp;You want to stay away from lsof on Solaris if possible. It uses a lot of resources to get its info and it uses private interfaces in the kernel and so can stop working with the application of a patch. &nbsp;Netstat might do what you want or even kstats. It depends on the answer to the first question.

Basically we have applications running instances. These applications run in the application port something lie 27810. We do monitor the application process in Unix but we would also like to monitor the port if there is any activity. By checking the process running we cannot find out if it is hanging.<br />
<br />
All are TCP application ports that are used to run our application instances in Websphere 6.0<br />

<div>
if it is not a standard application (e.g. http) then you need to write your own tool that will interact with the application over that port and send / receive some data.<br />
<br />
you can do this with telnet and expect if the protocol / application exchange simple text 
</div>


<div>
If the problem you are trying to diagnose is a hang, then you need to make sure that there is a &quot;null&quot; function in your application, and then periodically call this &quot;null&quot; function to verify proper functioning of the application.

Hello Peter,<br />
<br />
Could you please let me know where would this &quot;snoop&quot; binary executable present? Is it in /usr/bin? I am not able to run in my Solaris system. When i type &quot;snoop&quot; it says &quot;not found&quot; or does it come as a separate package? Or is it something like only a Administrators can run?<br />
<br />
Regards.<br />
Hari.

Port Monitoring using Shell Script

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.

Unix OS

The term 'shell' refers to a general class of text-based command interpreters most often associated with the UNIX and Linux operating systems. Popular shells include Bourne, Debian Almquist (dash), Korn (ksh), Bourne Again (bash) and the C shell family (csh). Some view the DOS 'cmd' prompt as a minimal shell of sorts. It is also possible to install Cygwin on Windows and emulate a full Unix environment with complete shell capabilities. Terminal emulators, such as xterm, GNOME Terminal and OS X Terminal, can be used to access shell.
