iptables doesn't work like that. It's a layer-3 subsystem (and to some extent layer-2) and doesn't know about things like domain names in any meaningful way. You can block access to an IP address, and if it so happens that the hostnames domain[12].com and sub[12].domain2.com resolve to IP addresses which themselves host no services for other domains, you ...

Most software installation programs for Windows require Administrator rights to function properly. This is an artifact of the design (or lack thereof, some might say) of the Windows platform. While there is an increasing trend toward software that installs only within the writable directories accessible to a limited (i.e. non-Administrator) user (things like ...

It's obviously possible to do this, and it's no more (or less) risky than putting up any other content on your server and make it public.

First and foremost, it's usually recommended that you replace your "domain.com" hosting to be a permanent and visible redirect to "www.domain.com". Usually, it's done either inside your web panel or in your webserver's configuration file with something similar to that (apache2 example) : <Virtualhost *:80> ServerName domain.com RewriteEngine ...

SPF records are per-domain, not per-server. They're essentially a list of IPs that are specifically allowed to send mail on behalf of a particular domain. Your SPF record for server.com handles emails with from addresses of @server.com. If you want to apply SPF to emails with addresses of @different-domain.com, then you need to add an SPF record to ...

You are missing some configuration in your virtual host settings. As explained in Apache docs you need to specify following options for your named virtual host: ServerName www.domain.tld ServerAlias domain.tld *.domain.tld DocumentRoot /www/domain ServerAlias is optional, but usually you will want to use it. In your case you need to specify: ServerName ...

Assuming the changes were all correctly made, not much you can do except wait it out. See: http://support.hostgator.com/articles/hosting-guide/lets-get-started/dns-name-servers/propagation-times http://support.godaddy.com/help/article/1746/what-factors-affect-dns-propagation-time

Setup a DNS, specifically an A record, which points your mydomain.com to your IP address. You can add multiple A records for different sub-domains.

As mentioned by @MadHatter that iptables rules are not used like that and for squid you have to Allow some IP’s to allow access to some specific sites. Please follow this steps to do that : Add this Lines to your Squid.conf File. acl allow_ip src “/etc/squid/allow_ip” acl allow_ip_site url_regex “/etc/squid/block_ip_allow” http_access allow allow_ip ...

Will creating the DC (and by extension, domain Y) on domain X cause any issues? You cannot have a domain controller for one domain as a member of a different domain. Domain controllers, in effect, are the domain for which they're on. Will these two domains conflict with each other if I don't initiate a trust relationship between the two? The ...

Now I used http://www.brandonchecketts.com/emailtest.php for testing this configuration. It gives me gaia.server.com as the Helo Address and email1@server.com as the From Address. But then it looks up the SPF record for the From Address domain server.com. The default specification of SPF is check the sender domain part. Whenever some server sent you a ...

Only DC in the domain If you are absolutely 100% positive no one is: authenticating to the box, and you are not using any Active Directory functionality for your sharing (such as AD groups for permissions on the share), and you have no dependencies on AD such as Exchange Server or some other LDAP-integrated product, and none of your machines are members ...

Your DNS servers have not been updated. The X.gtld-servers.net all point to 208.71.11.178/179 You have to log onto your Registrar's control panel and update the nameservers there. Updating the nameservers on the nameservers themselves achieves nothing. Your wizgousa.com nameservers are out of sync with the GTLD servers, and that has to be fixed by the ...

You seem to have mismatched glue records for the domain wizgousa.com. Those nameservers themselves are returning the correct information, if you know where to find them, but the root nameservers still seem to have old addresses for them. To resolve this, the owner of wizgousa.com must update the glue records with the domain regsitrar.

HTTP is port 80. You need to move it to port 80. No other way other than using it in a frame within another site on port 80 (URL hiding) The browser does not know that your site is on port 808. With http:// he aumatically tries port 80 because this is the standard port. Same with https:// it automatically tries port 443, which is assigned to HTTPS. If you ...

You haven't described the parameters of the exercise enough to make answering in a way that's acceptable to your instructor apparent. I'll take a stab for fun ('cuz, ya' know, I like answering questions for fun), though. Presumably, since you mentioned "domains", you have three DNS servers hosting Active Directory-integrated DNS zones. These three DNS ...

Assuming that you can without fail set wildcard (*.example.com) in DNS on your domain (if not, you can move your domain to for example freedns service). DNS service only translate domain to IP, i'ts not related to any service (http, ftp, smtp) so it can't redirect http request from one to different domain. But you can: Point *.example.com to some other ...

This is already said in Bernie White's answer comments, but just to make it clearer for newcomers: Execute: C:\Windows\System32\sysprep\sysprep.exe /generalize /oobe /reboot Then rebind to the domain and reboot.
