Following steps work for F29 for F31 look here

On the remote host

cat /etc/redhat-release
Fedora release 29 (Twenty Nine)

Install packages

su -c 'yum install qemu-kvm libvirt NetworkManager tinyproxy'
sudo systemctl start libvirtd
sudo systemctl enable libvirtd
sudo systemctl start tinyproxy

Create a crcuser

adduser crcuser
passwd crcuser
usermod -aG wheel crcuser
sudo passwd -d crcuser

# test if crcuser needs password
$ su crcuser
$ whoami
crcuser

Setup CodeReady Containers

su crcuser
# Goto https://cloud.redhat.com/openshift/install/crc/installer-provisioned
# download the CodeReady Containers archive 

wget https://mirror.openshift.com/pub/openshift-v4/clients/crc/latest/crc-linux-amd64.tar.xz
tar -xvf crc-linux-amd64.tar.xz
crc setup

# the pull secret is also available on https://cloud.redhat.com/openshift/install/crc/installer-provisioned
# Copy and paste it when prompted by crc start
crc start

Save the login details

''eval $(crc oc-env) && oc login -u kubeadmin -p e4FEb-9dxdF-9N2wH-Dj7B8 https://api.crc.testing:6443' 
INFO Access the OpenShift web-console here: https://console-openshift-console.apps-crc.testing 
INFO Login to the console with user: kubeadmin, password: e4FEb-9dxdF-9N2wH-Dj7B8

Install oc client

# Go to https://mirror.openshift.com/pub/openshift-v4/clients/ocp/latest/
wget https://mirror.openshift.com/pub/openshift-v4/clients/ocp/latest/openshift-client-linux-4.2.2.tar.gz

tar -xvf openshift-client-linux-4.2.2.tar.gz
cp oc /usr/local/bin

Setup tinyproxy

Edit the /etc/tinyproxy/tinyproxy.conf file. Comment out the Allow 127.0.0.1 line as it allows only access from within the VM Search for ConnectPort and add the following line:

ConnectPort 6443

Save the file and Start tinyproxy

systemctl start tinyproxy

On the Laptop

Install oc client

# Go to https://mirror.openshift.com/pub/openshift-v4/clients/ocp/latest/

wget https://mirror.openshift.com/pub/openshift-v4/clients/ocp/latest/openshift-client-linux-4.1.13.tar.gz
tar -xvf openshift-client-linux-4.1.13.tar.gz
cp oc /usr/local/bin

BROWSER: Setup SSH tunneling to access OpenShift console from browser

Edit /etc/hosts

127.0.0.1 localhost console-openshift-console.apps-crc.testing oauth-openshift.apps-crc.testing

sudo ssh root@<REMOTE_HOST> -L 443:console-openshift-console.apps-crc.testing:443

Give laptop password first and then the remote system password.
OpenShift console is available at https://console-openshift-console.apps-crc.testing

TERMINAL: Setup for oc client to work

# in a new terminal
export https_proxy=http://vm_ip:8888

# test api endpoint
curl -k https://api.crc.testing:6443

Now you can login using oc client tool

oc login -u kubeadmin -p e4FEb-9dxdF-9N2wH-Dj7B8 https://api.crc.testing:6443

To access routes

# get the route 
oc get routes
NAME     HOST/PORT                                  PATH   SERVICES           PORT   TERMINATION   WILDCARD
tekton   myservice-mynamespace.apps-crc.testing          tekton-dashboard   http                 None

Add the route to /etc/hosts file as given below.

127.0.0.1 localhost console-openshift-console.apps-crc.testing oauth-openshift.apps-crc.testing myservice-mynamespace.apps-crc.testing

SSH tunnel in a new terminal

sudo ssh root@<REMOTE_HOST> -L 80:myservice-mynamespace.apps-crc.testing:80

the UI is available at https://myservice-mynamespace.apps-crc.testing

+1 Thanks. I made the change

I have the latest which is 4.2.8 but I don't see tinyproxy anywhere yet. Have you seen this yet?

This was helpful, confirming it works with

crc version: 1.4.0+d5bb3a3
OpenShift version: 4.2.13 (embedded in binary)

on a CentOS Linux release 7.7.1908 (Core)

Able to connect from a Win10 machine using bash via terminal

And setup a SSH tunnel via PuTTY and Pagent for the browser console

can you please help me providing the steps ?
I want to connect to remote crc 4.5.9 runing on ubuntu from windows 10 client machine.

If you are unable to edit /etc/hosts or run dnsmasq file, then use kubectl port-forward to target a particular service from your client machine.
