I want to have an ftp account thisaccount#mydomain.com that does not access my normal mydomain.com server but accesses any other remote server from some service provider.
How do i do this with still keeping mydomain in the address? Which service providers would just give me an ftp account without moving my domian there? Do i need to investigate ftp redirects?
Any direction appreciated?
One option is to setup a dns CNAME to yourftpprovider.com from ftp.mydomain.com.
An example entry in the zone file for mydomain.com:
ftp IN CNAME yourftpprovider.com.

I am trying to build a new DNS, which will act as a proxy for certain domain names and uses a public DNS as upstream.
My understanding of DNS:
Client asks DNS (x.x.x.x) about example.com
DNS will look up inside its zones (or parent and root) and find example.com can be found at i.i.i.i
DNS will send i.i.i.i to the client.
Now, client asks the ip address of restricted.test and DNS server knows it is a restricted website, so instead of giving the direct ip to the website, it gives it's own proxy address p.p.p.p to the client.
Please correct me if I'm wrong till now, but when the client tries to connect to p.p.p.p how the proxy server knows which website the client wants to go in?
I really want to know how these work under the hood
Thanks in advance.
This mechanism you are asking about is the Proxy Auto-Configuration (PAC) file.
Read more about it here :
https://developer.mozilla.org/en-US/docs/Web/HTTP/Proxy_servers_and_tunneling/Proxy_Auto-Configuration_PAC_file
And here :
https://www.websense.com/content/support/library/web/v76/pac_file_best_practices/PAC_explained.aspx
Essentially in corporate networks, a PAC file is pushed out to every computer, and browser settings are also configured to enable the PAC file. But it can also be done manually. Just check your browser proxy settings to see the location of the PAC file it is pointed to.
I tried creating an Amazon EC2 instance with an elastic IP address. In there I deployed a MEAN app by Bitnami.
On the other hand we have a CPanel (not deployed in amazon, I think it's Apache, not sure, I'm not the one who deployed it)
Cpanel is already pointing to www.example.com so we can access cpanel via www.example.com:2082 but the default www.example.com:80 is blank/empty. We are using Cpanel for our mailing server.
What I need to do is to point Amazon EC2 public IP and DNS to www.example.com:80. Can I set it up in Cpanel DNS Zone Editor? or do I need to set up Amazon Route 53? what do I need?
If I create a new A record in Cpanel DNS Zone editor for Amazon I lose access to Cpanel www.example.com:2082. I'm really confuse right now. Please Help.
You need to introduce a Proxy server in between to do this, As in DNS you can't set the ports, for each type of requests ports are already defined.
You can add nginx or haproxy or any other reverse proxy server, which will accept all the requests and passes on the request to appropriate hosts on appropriate ports.
I know it's a bit late but just in case you still need it or someone comes across this:
No need for a proxy.
You point the A record for example.com to EC2 IP.
CNAME for WWW to example.com
Then you should have an A record for mail.example.com for your cPanel IP
Your MX records should point to mail.example.com and not to example.com.
And you can access cPanel at mail.example.com:2082 or whatever the server's IP or main hostname is. The main hostname has the advantage that you can use port 2083 for SSL cPanel connections
Just make sure the e-mail clients use mail.example.com and not example.com as the connecting mail server.
I am working on a project, where I have a domain xyz.com, I have been requested that a subdomain example abc.xyz.com should point to website which has ipaddress
example http://199.152.57.120/client/ and when a visitor browse abc.xyz.com it should open the website hosted on http://199.152.57.120/client/ but by hidding this ip address the visitor should always see abc.xyz.com.
I also need to host another website to xyz.com
domain which is registered with x company and webhosting is taken for z company both different.
It is something similar to Reseller business where Reseller company assign a website to their client on their custom domain.
You can make A record in your DNS Server that IP address 199.152.57.120 pointing to abc.xyz.com
and then make same configuration in your web hosting that nginx/httpd virtual host point to directory /Some/Directory/client
you can read this for nginx https://www.linode.com/docs/websites/nginx/how-to-configure-nginx
It can be easily done in domain provider DNS zone. Just add A record where you will provide subdomain ex: abc.xyz.com and connect to adress ex: 1.2.3.4 How to do that in your domain provider, just check help pages for DNS records.
Alternatively you can install proxy software like NGINX and make subdomain redirect.
Example setting:
Do FTP clients (like Filezilla for example) expose my IP address to webhosting services while uploading/downloading files from their server?
If yes, then are there any FTP clients out there that can conceal my IP address?
You can't. You need an IP address in order to access any server. It's fundamental property of the internet.
Use a service like DynDNS or No-IP. But even then, you can't hide your IP, just cloak it.
Yes, they do. If you directly make contact with any server, your IP address will always be "exposed".
One option would be to connect indirectly (through a proxy for example), in that case the server you are contacting will see the proxy server's IP address.
I want to access a FTP Server, that is firewall protected meaning only IP addresses that have been added to the safe list may access the FTP file.
And The IP address of my website has been added to the safe list of the firewall.
I am using Filezilla to connect to it, but it is not allowing me to connect to the FTP server since my PC has a different IP.
Please suggest me a way to connect to the FTP server.
Thanks In advance....
If you can ssh/telnet into your host, then you could use the command line ftp.
Another option is to use a web-based ftp client that is installed on your web server (such as http://www.phpwebftp.com/ if you have PHP).
Run an ftp client on the allowed server; or, persuade the ftp admin to add your PC's IP address to the whitelist, and ensure and/or pray that it doesn't change (maybe pay your ISP extra for a static IP); or, use a proxy on an authorized server. The first option is definitely the most painless, assuming you have shell access to your web server (and if not, what sense does it make to have it on the authorized list?)
Some popular command-line clients you might find installed on the server include ftp (sic), ncftp, curl, wget, lynx, and w3m. The last two are actually terminal-based text-only web browsers.
If you have shell access to your server, you could create a SSH-tunnel like this:
ssh user#example.org -L 21:127.0.0.1:21
then you can connect to the FTP-server using localhost:21 from your pc.
