I just tried this wget of the drupal tar.gz file you mentioned. See this code block (scroll box right & left as needed):

[notroot@mysystem mydownloads]$ wget http://ftp.drupal.org/files/projects/token-7.x-1.5.tar.gz

Are you using dhcp on the system you are facing the public internet with? If so, your /etc/resolv.conf is likely being generated automatically.

If needed, add another dhcp server such as google's public dns (see this link for the dns ip addresses) if your dns server you're behind can not resolve the domains you cited. If you are using dhcp, if you add a nameserver to your /etc/resolv.conf, it will not be persistent across network restarts or reboots.

Lastly, I was able to ping and do nslookups against these domains.

[notroot@mysystem mydownloads]$ nslookup www.elitewebdev.com
-truncated output-
Non-authoritative answer:
www.elitewebdev.com canonical name = elitewebdev.com.
Name:   elitewebdev.com
Address: 198.187.31.96

[notroot@mysystem mydownloads]$ nslookup ftp.drupal.org
-truncated output-
Non-authoritative answer:
ftp.drupal.org  canonical name = ftp.osuosl.org.
Name:   ftp.osuosl.org
Address: 140.211.166.134

Hi James,

See the last posts following this one....

No one likes errors like this hanging around.

• I mentioned that any changes to an automatically generated /etc/resolv.conf would be non-persistent.
  • I brought up editing the /etc/resolv.conf with a 'nameserver 8.8.8.8' just in case you needed an additional dns search for your program to resolve the path since it seems it can not look it up. You can edit the file while the network is active and then --do not-- restart the network or reboot and try it again. Your mileage may vary and there are of course other factors to consider, but incremental troubleshooting is relevant.

When you say you get updates and notifications through RHEL Subscription and Administrator update, are you saying that you actually receive Joomla and Drupal updates via Red Hat's Subscription and Administrator update???? That part was not clear. I would suspect you do not receive Joomla/Drupla updates via Red Hat Inc.

Because your Red Hat updates work, and you can ping those sites, that is of course just an initial test. The fact you can manually download those files is also just an initial test. Now that it is known those initial steps are ruled out, any subsequent troubleshooting can take place.

• Did you perhaps create a yum repo file in /etc/yum.repos.d/some.repo (replace "some" with an actual name you may have used) for any updates? If you -do- have a repo file for Joomla or Drupal, is it set up properly?

• What did you invoke in order to attempt an upgrade, was it a yum update command or some command that is part of drupal or joomla? That part is missing in your description.

• Did you look at the forums and community portals I mentioned in the first post?

  • Since your problem is obviously not with Red Hat updates, check the community portal for Drupal & Joomla as mentioned to see if anyone else is experiencing issues.
  • It would be hard to believe that you are the only who has faced this issue.
  • I would suspect Joomla's and Drupal's forums would be a magnet for people discussing such issues.

The only other immediate thing I could think of is (less likely, worth a try) your firewall. Temporarily shut off your firewall and try the update process.

• Do you have support with Joomla or Drupal, or are you just using the open-source programs without support?

Also, (a long shot) run the below to see what is going on when you attempt an update, and then take the output and put in wireshark. (you can redirect output too, save the file and open it in wireshark).

tcpdump -i ethx # replacing 'x' with your network device

Kind Regards....

James,

Regarding Drupal, check to see if this bit from their website's community documentation (Last updated May 18, 2014.) helps.
