This small write up should help if some one is trying to configure the squid proxy with the authentication.
How to set up squid proxy for testing the HTTPS-ORMI Connections.
open the file /etc/squid/squid.conf
Step 1.
======================
Add the following after this line
#Default:
http_port 9090
This is the port you need to specify for the proxyPorts.
Step 2.
===========================
Append the SSL ports to the list of the SSL ports , in this case I added port
8888.
acl SSL_ports port 443 563 8888
Step 3
=============
Add the following after this line ,
here I added the proxy_auth as required , and my IP address wher I am going to
access the proxy ports.
# And finally deny all other access to this proxy
http_access allow localhost
acl pass proxy_auth REQUIRED
http_access allow pass
acl allowed_clients src 152.69.168.138 152.69.168.139
http_access allow allowed_clients
#http_access deny all
Step 4
==========
Here I need to use the Authentication program that I will be using for the passwords.
And make sure you have the following lines in , after this line
#auth_param basic program
auth_param basic program /usr/lib/squid/ncsa_auth /etc/squidusers
auth_param basic children 5
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours
Step 5
=========
Create the /etc/squidusers file ,
/usr/bin/htpasswd -c /etc/squidusers ravi
Give the password as ravi
/usr/bin/htpasswd /etc/squidusers test
Give the password as test
Start the squid proxy servers using the commands ,
service squid restart
After this write the RMI client , for the EJB's
SessionEJBClient.java
