Dear Ricky,

Still I could not solve the proxy proble. I cannot browse the https sites. I have configured the squid proxy again just according to your squid tutorial but still the same problem is taking place.

I will be delighted if you kindly look into this problem

With thanks

Saif

Dear Ricky,

I made follwing changes in /etc/squid/squid.conf file

Code:

http_port 8080
cache_peer proxy.mydomain.com   parent   8080   3130

cache_mem 64 MB

acl my_LAN src 192.168.10.0/24
http_access allow my_LAN

This is all. If u need the whole squid.conf file then please advice me how to send that to you.

Best regards
Saif

Thanks for ur reply. I use Internet Explorer 6.0 as my browser. In the proxy settings the option available are

http

Dear All,

Good Day. I have configured Squid Proxy server in RedHat 9.0. But if I use the proxy server address in my browser settings I can not browse secure http sites.
I have not changed the default acl of SSL_ports and Safe_ports.
I am using port 8080 as http port.

Please advice what to do?

With thanks
Saif

Sorry..I tried with your solution but it is not working. Please see the text inside that file(firewall). It is like this:

#!/bin/sh
IPTABLES=/sbin/iptables

$IPTABLES -F INPUT
$IPTABLES -F OUTPUT
$IPTABLES -F FORWARD

....... and bla bla bla

Then I did followings:
1. #chmod 755 firewall
2. #vi /etc/rc.d/rc.local
/etc/rc.d/firwall

Please note that I can run it if I put the commands
 sh /etc/rc.d/firewall
But none of the chains are accepted.

Now when i put the same chain directly it accepts all

I do not know why and where I am making a mistake.

Please help

With thanks and regards

Hi all,
I have created a iptables firewall file named 'firewall"  in /etc/rc.d and changed its mode to 711. In rc.local I have put 'sh /etc/rc.d/firewall'  but unfortunately the file is not being executed during restart.

When i run, sh firewall I get error message. But when I put the iptables one by one, all the rules are accepted.

Can any one help me. Thanks in advance

Saif

Thanks for your reply
In fact I want to extract attachment of a particular e-mail account and I need to share this in a Windows PC using Samba. Main point of consideration is that these extractions is used to operate some other system

I know with procmail it is possible but do not know how.

I use sendmail in my Linux Mail Server (RedHat 9.0). I want to extract all incoming attachment of a particular e-mail account (like name@mydomain.com) to a folder (suppose /attachment).

Is there any body can help me to do so.

With thanks and regards
