In general, all traffic on the Internet has a beginning and an end point Often, this is referred to as the client and the server.

The server listens on well known ports. The client generally uses whatever is available.

When you run HTTPD on your machine, it is generally acting as a client, listening on port 80, or port 443 if using SSL.

When you use YUM to access their repo services, their server is generally listening or port 80, or port 442 if using SSL.

So, when you block HTTPD on your computer, you are not blocking that service on another server, like YUM, because to access a repo like YUM or GIT you are acting as a client, accessing a server. When you block or disable HTTPD on your computer, you are simply blocking access to your server, locally.

You should probably do some homework and learn some basics about client-server processes.

NAME
yum verify plugin SYNOPSIS
yum [options] verify [package ...] DESCRIPTION
This plugin extends yum with some commands that give verification information on the installed system, much like rpm -V. You can change how the verification is done and which files it applies to. added yum commands are: * verify * verify-rpm * verify-all all of which take the same arguments as the list yum command, obviously you can only verify packages that are installed on the system. verify Is the generic verification command, and is intended to give the most useful output. It removes all false matches due to multilib and ignores changes to configuration files by default. verify-rpm Is meant to be 100% compatible with rpm -V output, and any differences should be considered as bugs. verify-all Is used to list all the differences, including some that rpm itself will ignore. GENERAL OPTIONS
These are the options added to yum that are available in the verify commands. They are: --verify-filenames This option is used to limit the filenames that the packages will perform verification. --verify-configuration-files This option is only useful in the generic verify command, and will enable/disable verification of files that are tagged as configu- ration files. EXAMPLES
To do the same as rpm -Va, use: yum verify-rpm To verify the packages starting with the name yum, use: yum verify 'yum*' To verify the binaries that are in a bin directory, use: yum verify --verify-filenames='*bin/*' To verify all include files, Eg. for multilib problems, use: yum verify-all --verify-filenames='/usr/include/*' SEE ALSO
yum (8) yum.conf (5) the verify.conf file in /etc/yum/plugins.d AUTHORS
James Antill <james.antill@redhat.com>. BUGS
Currently yum-verify does not do verify-script checking or dependency checking, only file checking. Should you find any other bugs, you should first consult the FAQ section on http://yum.baseurl.org/wiki/Faq and if unsuccessful in finding a resolution contact the mailing list: yum-devel@lists.baseurl.org. To file a bug use http://bugzilla.redhat.com for Fedora/RHEL/Centos related bugs and http://yum.baseurl.org/report for all other bugs. James Antill 01 March 2008 yum-verify(1)
