## [check-cdn-connection](check-cdn-connection)

This script can be executed by the customer in a RHEL system registered and with the entitlement/subscription assigned. Based on that, the server will try to reach some CDN links based on the entitlements already assigned to it.

There is a help that will be as below
```
# ./check-cdn-connection.sh -h
./check-cdn-connection.sh to check the first 5 urls of each entitlement
To see in details, execute ./check-cdn-connection.sh --verbose
```

If you just execute the command, the output will be as below
```
# ./check-cdn-connection.sh
Found some entitlements

```
Note. Here we are checking for `repodata` dir on some URL and also `repomd.xml` file. The PASS information will be present ONLY if both information are present.

If you would like to see more information about the query, normally, it will be necessary when the connection is failing, we can pass the flag `--verbose`, and the output will be as below
```
# ./check-cdn-connection.sh --verbose

Entitlement: 2228110793913314193.pem
