This is not comment, its my Query, can you reslove it.
Sir, I am using Squid 2.6 (stable version) as Proxy Server as well as running Window based ISA Proxy in the same environment. There are two proxy servers are running one on Squid and other one on ISA. I am facing a problem to configure Gmail Account in Outlook with the Squid proxy settings, the error was appeared / shown and whiles I using ISA proxy at the same time error was resolved. There are some Squid settings issues which is blocking the settings of Gmail in Outlook under Squid proxy.
I have checked the error on all forums and changed the setting according to their replies / suggestions (like changing in IPtables, open ports 587 & 995 etc). I also changed the Squid version 2.5 stable and configure squid as a Transparent Proxy Server, but error is not resolved.
Sir, I need your help in this regards.

Frankly I hate ISA with a passion… I’ve found removing ISA and using other security measures is far better. Without actually working on your setup I’m not sure what to tell you… other then get rid of ISA..
Hi, i like your business. can you give me some videos on related to cloud computing. And can you send some links related to online Job.
1. Make a file in /etc/rc.d/filename
2. save the below text in that file only change the IP’s according to your network, In my case i have the Live IP on my eth0 and the private ip on eth1.
#!/bin/bash
/sbin/iptables -F
/sbin/iptables -t nat -F
/sbin/iptables -t mangle -F
/sbin/iptables -X
#———————————–INPUT CHAIN——————————————-#
/sbin/iptables -A INPUT -s Your Public IP/Live IP -p icmp –icmp-type echo-request -j ACCEPT
/sbin/iptables -A INPUT -s Your Public IP/Live IP -p tcp –dport Squid Port -j ACCEPT
/sbin/iptables -A INPUT -m state –state ESTABLISHED,RELATED -j ACCEPT
/sbin/iptables -A INPUT -m state –state NEW -i ! eth1 -j ACCEPT
/sbin/iptables -A INPUT -p tcp –dport 80 -j ACCEPT
/sbin/iptables -A INPUT -p tcp –dport Squid Port -j ACCEPT
/sbin/iptables -I FORWARD -p tcp –dport 25 -j ACCEPT
/sbin/iptables -I FORWARD -p tcp –dport 110 -j ACCEPT
/sbin/iptables -A FORWARD -i eth1 -o eth0 -m state –state ESTABLISHED,RELATED -j ACCEPT
#—————————Transparent Proxy(PREROUTING)——————————-#
/sbin/iptables -t nat -A PREROUTING -i eth1 -p tcp –dport 80 -j REDIRECT –to-port 8080
################################Source Nating(POSTROUTING)——————————#
/sbin/iptables -t nat -A POSTROUTING -s Your Private IP/LAN IP -j SNAT –to Your Public IP/Live IP
echo ’1′ > /proc/sys/net/ipv4/ip_forward
3. Save the File.
4. execute the file /etc/rc.d/filename
5. Service IP tables restart
6. chkconfig –levels 235 iptables on
Cheers

if doesnt work then Please run the following commands
modprobe ip_conntrack_ftp
modprobe ip_nat_ftp
NoW cheer
:D
Eli i am taking your lecture about introduction to cloud computing.i need more lectures on cloud computing because i want to make a project on it.i appreciate your work on it.but i need more if u can.thanx
hi every body i am hamid from afghanistan and my problem is login and the password of backtrack 5
Hamid,
what do you mean by login and password, can you please explain this a bit.
Hello,
I hope you are doing well and fine, you are really awesome, for the first time in my life I watch a lecture video till the end of it without pausing or postponing watching it, thank you very much for this and good luck.
Can tell me how to configure the DNS on Public IP Address. A little bit confusion is running on my mind that how to setup domain for example http://www.next.com with corresponding public IP.
You do this on the DNS Control Panel provided by whomever you bought your domain name from. You login and the change the @ value to be your public IP Address
great videos
Hello Sir
Sir i want to get a rented server for my voip switch there is alot of datacenter’s they offer the dedicated server ,But Sir you know there is some datacenter’s they give shared server on the name of dedicated server Sir now i want to know How we know that one is dedicated or shared (Like VMWARE ),…
The company will have different rates… If it’s a reputable company it will say a Virtual Server will cost X, and a dedicated server will cost Y. Such as if you go to 1 and 1′s server page: http://order.1and1.com/Server . Virtual Servers start at $29 a month and dedicated ones start at $59.
Thank you very much sir for quick reply..sir one of them they offer me the following configuration at 150$ per month.plz check this configuration is good on 150$ per month.
Intel Core2Duo E8200 – 2.66GHz – 1333MHz HT Speed
Core Name: Wolfdale
Memory (RAM): 2gb DDR2
Hard Drive: 250GB SATA2
Outbound Bandwidth: 2000gb
Inbound Bandwidth: Unmetered
IP Allocation: 8 IPs (5 Usable)
Seems high.
You can get this from 1and1.com for $99 a month:
Performance
Processor Intel® Xeon® E3-1220 Speed 4 Cores x 3.1 GHz
(3.4 Turbo Boost) RAM 12 GB DDR3 ECC Hard-disk space 1,000 GB

Hi
plz update me about internet load balancing can we perform this task on Linux or we need some kind of hardware…?i want to combine my 3 internet connections on one PC (2 DSL and 1 Wimax).
thank you
There are a number of ways to do this. It really depends on what you are trying to accomplish…
Sir, i have some query here. Some cloud computing stuff that made me confused.
Do you have any video about Personal Cloud? This personal cloud is the new market emerging.
I am confused on whether is it the same thing as public cloud? Like Google Apps, hotmail, dropbox…i first thought it is a public cloud, but then researcher told me it is also a personal cloud. So what is the differences between personal and public cloud?
I like your video which gave me a simple layman explanation on tech stuff, so whether you can help me with the problem i faced. Hope to have some classes on this. Thanks.
Personal vs Public is simply who owns the hardware. If YOU own 10 servers and configure them to be in a cluster for virtualization then its a private cloud. If you pay AMAZON to host your virtual servers thn its the public cloud.
So what is the personal cloud really mean? Amazon is the public cloud but also ppl claim it as the personal cloud.
Dear
Please i want to know more about cloud computing&IP_VPN .
Please can you send me Videos&Presentation about these
thanks

Hi,
I watched your Introduction to Virtualization and glad to say its a really good overview. I would like to know some more stuf related to virtualizations. They are:
1. How the virtual CPUs are scheduled during process execution on physical CPUs?
2. When we are using AW Services (means the instances) how Amazon is scheduling or migrating the jobs in CPUs?
3. When AWS have over allocation is it possible to use the physical CPUs to their max capacity or still enterprises are unable to use the spare CPU cycles? Means enterprises are only enable to use 20 to 40 % of CPU capacity…
Thanks for your time and reply..
Hi,
Am new in IT line, i just started the training, when i search through your website, its really interesting, though am having lots of difficulties to cope, i would appreciate if you can assist me on some of my questions, Describe some software solution. What is an IP address management. Thanks.
