Rackspace yum install git cURL 443 Connection refused

Trying to install git in a RHEL Rackspace Dedicated Server, but am getting the following after typing in this command: yum install git

Curl error (7): Couldn't connect to server for https://rhui.rackspace.com/pulp/mirror//content/dist/rhel8/rhui/8/x86_64/appstream/os [Failed to connect to rhui.rackspace.com port 443: Connection refused]

Could this be a firewall issue? This is from a clean build. I have the same problem with trying to do a yum install openssl-dev

Curl is installed, but not sure why it's refusing to connect. Is there anyways to get the files on the server linked to a repository on bitbucket through git? This seems like this should be pretty basic stuff to me. Not sure why it's even trying to connect to a rackspace url? Apologies if this is a dumb question, but have looked everywhere for help on this and doesn't seem to be anything online about this. The videos I watched show it working as expected. I even tried installing the dependencies and can't get that to work either yum install git-core

I have also tried the following:

wget https://github.com/git/git/archive/v2.33.1.zip

unzip v2.33.1.zip

cd git-2.33.1/

make prefix=/usr/local all install

This method works up until the last line where it states no such file or directory #include <openssl/ssl.h>. Than looking up that figured I need to get openssl-dev installed, but not sure if that's leading me down a rabbit hole. Really just want to get git installed on this server if possible?

Ok, it seems I get the 443 Connection refused error anytime I try to install anything with yum, or dnf e.g.:

yum groupinstall 'Development Tools' provides the same error pointing to the same url.

Can you reach other Rackspace sites? You can test with `curl -v https://mirror.rackspace.com/` ... look for `* Connected to mirror.rackspace.com (74.205.112.120) port 443 (#0)`

your machine is configured to reach Rackspace's "Red Hat Update Infrastructure" (RHUI) servers -- https://access.redhat.com/products/red-hat-update-infrastructure . "RHUI allows cloud providers to locally mirror Red Hat-hosted repository content"

My guess would be a selinux misconfiguration

the easy answer: give us a call or submit a ticket and we can look at your firewall to see what's going on.

the DIY answer: since you can reach "https://github.com" but not "https://rhui.rackspace.com", you might have outbound firewall rules configured, or servers at "rhui.rackspace.com" aren't behaving.

check your outbound firewall rules. For either case below, you'll want to permit traffic to the destination host (rhui.rackspace.com) on destination port 443 with protocol TCP

  1. software firewall
    for firewalld or iptables, try sudo iptables -vnL OUTPUT and look for "policy ACCEPT" (the default)

  2. hardware firewall
    in the MyRackspace portal under Network > Firewall Manager V2, look for the sections 100, inside, or FW-INSIDE ACL which cover outbound traffic

Thanks, it was an IP Tables issue, didn't have anything in there so I added this bit here: `iptables -A OUTPUT -p tcp -m tcp --dport 443 -j ACCEPT` and was able to download git after that with yum.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
