This is what worked for me.
In my .cshrc file I added the following lines.
set system=`uname -n` # name of this system.
set myname=`/usr/ucb/whoami` # user name
set ip_addr=`ypmatch $system hosts` # IP address
set prompt="[$myname@($ip_addr)]$cwd-> " #command prompt.
alias cd 'cd \!* ; set prompt="[`whoami`@($ip_addr)]$cwd-> "; echo -n "2;`dirs`1;`dirs`"'
With a result of my command line looking like:
[username@(ip address nodename ]/home/username->
And the title of the xterm window dynamically changing to the dir I cd too.

ext_file_userip_acl
ext_file_userip_acl(8) System Manager's Manual ext_file_userip_acl(8)
NAME
ext_file_userip_acl - Restrict users to certain IP addresses, using a text file backend.
Version 1.0
SYNOPSIS
ext_file_userip_acl [-dh] [-f file name ]
DESCRIPTION
ext_file_userip_acl is an installed binary. An external helper for the Squid external acl scheme.
It works by reading a pair composed by an IP address and an username on STDIN and matching it against a configuration file.
OPTIONS
-d Write debug info to stderr.
-f file Configuration file to load.
-h Display the binary help and command line syntax info using stderr.
CONFIGURATION
The squid.conf configuration for the external ACL should be:
external_acl_type type-name %SRC %LOGIN /path/to/ext_file_userip_acl -f /path/to/config.file
If the helper program finds a matching username/ip in the configuration file, it returns OK , otherwise it returns ERR .
The configuration file format is as follows:
ip_addr[/netmask] username|@group|ALL|NONE
Where ip_addr is a dotted quad format IP address, the netmask must be in dotted quad format too.
When the second parameter is prefixed with an @ , the program will lookup the /etc/group file entry for the specified username.
There are other two directives, ALL and NONE , which mean
