Full Discussion: Command to know port no
Operating Systems Solaris Command to know port no Post 302130230 by zazzybob on Friday 3rd of August 2007 10:49:48 PM
Old 08-03-2007
I actually wrote a fairly comprehensive script to do this a while back

Code:
#!/bin/bash

# use this where lsof (for lsof -i tcp:<port>) isn't available

AWK="/usr/bin/awk"
ECHO="/bin/echo"
PARGS="/usr/bin/pargs"
PFILES="/usr/bin/pfiles"
PS="/usr/bin/ps"
SED="/usr/bin/sed"

${PS} -ef | ${SED} '1d' | while read PS_LINE; do
   PS_PID=$( ${ECHO} "${PS_LINE}" | ${AWK} '{print $2}' )
   PS_PROC=$( ${PARGS} ${PS_PID} | ${SED} -n '1p' | ${SED} 's/^[0-9][0-9]*:[    ]*\(.*\)$/\1/' )
   PORT_USAGE=$( ${PFILES} ${PS_PID} | ${AWK} '/AF_INET/ { printf( "\t%s(%s)\n", $3, $5 ) }' )
   if [ "${PORT_USAGE}" != "" ]; then
      ${ECHO} "${PS_PROC} [PID: ${PS_PID}]"
      ${ECHO} "${PORT_USAGE}"
   fi
done

exit 0

Sample output...
Code:
...
        /usr/lib/inet/xntpd [PID: 366]
        0.0.0.0(123)
        127.0.0.1(123)
        192.168.xx.14(123)
        192.168.xx.15(123)
...

Cheers,
ZB

getusershell

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME

       getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

DESCRIPTION

       The  getusershell()  function  returns  a  pointer  to  a  legal  user  shell  as defined by the system manager in the file /etc/shells. If
       /etc/shells does not exist, the following locations of the standard system shells are used in its place:

	 /bin/bash		    /bin/csh
	 /bin/jsh		    /bin/ksh
	 /bin/ksh93		    /bin/pfcsh
	 /bin/pfksh		    /bin/pfsh
	 /bin/sh		    /bin/tcsh
	 /bin/zsh		    /sbin/jsh
	 /sbin/pfsh		    /sbin/sh
	 /usr/bin/bash		    /usr/bin/csh
	 /usr/bin/jsh		    /usr/bin/ksh
	 /usr/bin/ksh93 	    /usr/bin/pfcsh
	 /usr/bin/pfksh 	    /usr/bin/pfsh
	 /usr/bin/sh		    /usr/bin/tcsh
	 /usr/bin/zsh		    /usr/sfw/bin/zsh
	 /usr/xpg4/bin/sh

       The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.

       The setusershell() function rewinds the file or the list.

       The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.

RETURN VALUES

       The getusershell() function returns a null pointer on EOF.

BUGS

       All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.

NOTES

       Restricted shells should not be listed in /etc/shells.
