I had some test sites setup on a server that had one IP and utilized different ports for the site like this.
www.acme.com:5000
www.acme.com:6000
This worked great until a SSL certificate was installed on the server. Now the sites above are not coming up.
How do I configure them so that they come up again?
SSL can only segmented by IP and Port. You can however can run SSL over a different port than 443 by simply adding a binding for https and a different port.
In IIS 7.x, in the Bindings for the site, you would add one for SSL and change the port:
What would also need to happen, which isn't shown in this image is the selection of the appropriate SSL certificate which would need to be configured on the server. With that set, you would then access the site by going to:
https://mysite:1234/...

I purchased a domain through Amazon Route 53 and am hosting my Node.js/ExpressJS app on an Amazon Linux EC2 Instance server. I can get my site to run on my EC2 server by using the public IP:portNumber or by using the publicDNS:portNumber, but I am struggling to understand how to set up the record sets in the hosted zone section of the Route 53 console to have my website point to www.thedomainipurchased.com:portNumber. I also read somewhere that you can't add the port number onto the public ip like that, so I would like to know how to set up both records to do this. I'm new to DNS, which is why I've had such a hard time although I'm sure to some people this seems very simple so would really appreciate any feedback to be explained in as basic and simple of a way as possible. Record Set Picture here
DNS only provides a way to map names to the IP addresses of hosts. Except under very limited circumstances you can't include a port number. DNS simply isn't designed to do that.
Ports are determined by the protocol involved. If you use a web browser to connect via HTTP then it will default to using port 80. If you use a web browser to connect via HTTPS then it will default to using port 443. When you send e-mail the default port is 25. When you SSH into a server the default port is 22. And so on. Default ports are essentially part of the specification for the global internet.

I am hosting and application in IIS. the application is a INTRANET APPLICATION.
Already the server has 2 application hosted in it with host names
site1.k.com and site2.k.com
k.com is my domain name.
I have give host name for my site as
site3.k.com
Do i have to make DNS entry for this.
If you have a wildcard dns entry such that <anything>.k.com goes to your server, then you don't need a specific DNS entry for site3.k.com, but it might make things easier down the road if you have it.
Of course, if you don't have the wildcard set up, and you need to have the url for site3.k.com work, then yeah, it'd be required.
Now, you mention that this is intranet ... if you have a windows server configured to broadcast that it's name is site3 via WINS service, then you might get away with not having the DNS entry, but this behavior is not reliable, because WINS may or may not route to remote sites, depending on WAN and/or VPN configurations, and will generally be a pain in the ass for support.

I have caught a hacker after looking through my site's FTP logs - it looks as if they have gleaned a list of passwords for several of my sites and are now connecting on a daily basis to upload spammy PHP files that perform header redirects to their sites. They always connect from the same IP address.
Blocking that IP and changing the FTP passwords is a given, but it seems so mundane and submissive. Is there anything I can do to this guy as he connects or once he's already in the system?
Some recommendations:
Change your FTP port. Most script kiddies use a port scanner to scan a list of IP addresses for TCP services. They mostly look for port 21.
Disable root login for SSH.
You mentioned this before, but make sure your password is secure and not written down on a post-it note on you computer monitor.

I'm sad to have to ask this question, but I'm not even sure of what to call what I'm trying to do, so Google isn't much help.
I'm doing some work on a company website from outside the company's network. Some of the assets on the site are loaded from a domain that is only visible from inside the company's network (QA) but there is a mirror of those assets on a public domain. How can I mask or forward requests to this internal domain (e.g.: http://qa.example.com/image.png) to the mirroring external domain on my laptop? (e.g. http://www.example.com/image.png). This is similar to what can be done using the host file for IP addresses. The reason I want to do this is so that the images aren't broken as I work on the site outside the office, and changing all the references in the web files is not an option. I'm on OSX Lion.
Again, sorry, dummy question, please don't flame :S
Thanks!
If the mirroring host (http://www.example.com) doesn't use host headers, you can do it through the host file, by mapping qa.example.org to www.example.com.
This will have your browser ask the www.example.com host for the http://qa.example.org/image.png. If www.example.com is configured to use host headers to control content served it will see the mismatched hostnames and fail to serve the content. In that case you need something more powerful.

What is proxy server exactly. What its purpose ?
there are two types of firewall: packet filters and proxies.
A proxy can have many purposes. Essentially it's a gateway that can restrict and/or log network accesses.
Maybe you're the admin of a network and you want to monitor the web traffic being accessed by company employees.
In that case you might have your client computers configured such that their web browsers / other apps are configured to access the internet through the proxy.
The proxy can then log what is being accessed - and by whom.
Proxies like squid specialise in caching frequently accessed network resources, in order to reduce bandwidth consumption.
There are many other uses, these are just a few. Hope this helps!
