OpenShift Client Tools (RHC) Setup Wizard
This wizard will help you upload your SSH keys, set your application namespace,
and check that other programs like Git are properly installed.
If you have your own OpenShift server, you can specify it now. Just hit enter to
use the server for OpenShift Online: openshift.redhat.com.
Enter the server hostname: |openshift.redhat.com| sajeer850#gmail.com
You can add more servers later using 'rhc server'.
The OpenShift server is not responding correctly. Check that
'https://sajeer850#gmail.com/broker/rest/api' is the correct URL for your
server. The server may be offline or misconfigured.
root#ubuntu:~# 'https://sajeer850#gmail.com/broker/rest/api'
I had the same error . When prompted to Enter the server hostname: |openshift.redhat.com| press "Enter key" , and then you will be prompted to enter username and password.

I used to connect remote servers provided by Linode and GCP and I use Visual Studio Code via Sftp extension and all works just fine. However, with the same set of configurations, I couldn't connect to my Aws EC2 server.
The following is the sftp.json (with sensitive information changed)
And the aws security setting is as following
The strange thing is that I can ssh connect to the server on the terminal and I can use filezilla to send file with the same credential as well. But somehow I can't connect to it via Visual Studio Code sftp or SSH remote extension.
I searched the anwser on the internet and found an answer that worked for me.
The problem has to do with the Ubuntu 22.04 default server default key setting and not with the VSCode.
The solution is adding
PubkeyAcceptedKeyTypes=+ssh-rsa
in /etc/ssh/sshd_config
and then restart the service on the server with the following command
sudo systemctl restart sshd

I have installed gitlab server using docker compose but after the installation I am not getting a default screen where we create first Admin user. Instead of that it is asking me to enter username and password.
If I see this correctly, the gitlab_root_password should be set in the Compose file. This should then be used to log in for the first time.

I got into trouble after installing Gitlab on CentOs7. For the first time I was redirected to the admin password creation page and after the password for the admin user, the server sent error.

The change you requested was rejected.
I had set the url value based on the site guide.
Set the external_url in /etc/gitlab/gitlab.rb:
external_url "https://example.com/gitlab"
I checked the links below for similar situations. I didn't find the right answer. My server was in the local area and had no internet access.

After Update Error: "422 The change you requested was rejected."
Error 422 after installing Gitlab on Ubuntu 16.04
I made a mistake when installing Gitlab. In the /etc/gitlab/gitlab.rb file I put the local gitlab address with https but due to the local server setup there was no "let's encrypt" service and I did not intend to access the site via ssl. I modified the address in the file and turne "https" to "http". After modifying the following commands, the problem was fixed.
sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart
I have a docker daemon/engine running inside guest (Ubuntu) virtual machine
and as per Docker Tooling for Eclipse instruction I had downloaded and setup the plugin in Eclipse Mars on my host Mac OS machine.
How do I connect to Docker running in guest VM from the host machine IDE.
As per instructions, I would need to enter TCP and authentication so how do I get these details to setup the connection?
I had tried with guest OS IP (i.e. tcp://127.0.0.1:2376 output of ifconfig command with local host IP) but was not able to connect.
Here are the steps I used to get Docker Tooling working in Eclipse Neon on Windows.
Open the Docker Quickstart Terminal
Execute docker-machine ls
Copy the URL (e.g. tcp://192.168.99.100:2376)
Click the Add Connection button in the toolbar for Docker Explorer
Provide a Connection name:
Select TCP Connection
Paste the above URL into the URI: edit box
Change tcp to https in the edit box
Select Enable authentication
Set the path to C:\Users\username\.docker\machine\certs
Click on Test Connection to verify
There are two parts to this. First, enabling the TCP socket (which I'll answer). Then, setting TLS authentication on the socket (which I'll link to but won't cover). The first part should get you up.
You'll need to edit the DOCKER_OPTS settings in /etc/default/docker in the VM. Edit this file and set DOCKER_OPTS to something like:
DOCKER_OPTS="-H tcp://0.0.0.0:2376 -H unix://"
Then, restart Docker (sudo service docker restart). This should get you a TCP connection that you can put in your Eclipse settings as:
tcp://10.0.2.15:2376
The second part (which is optional at this point) would be setting up the CA and certificates per https://docs.docker.com/engine/articles/https/. But I'd actually recommend just installing Docker Machine and provisioning your VM that way as it will create the needed certificates for you. Then, if your machine was named dev, you just point the authentication dir to ~/.docker/machine/machines/dev.
If Docker Daemon is running(i.e docker desktop running) in window task bar , not inside the VM , just get the URI from its context menu setting. In eclipse docker tooling perspective , we can connect to running docker daemon only by providing the URI.
I want a easy way to save, copy and edit files on a remote server. I'm using Eclipse as an IDE, what could be better for these tasks than RSE(Remote System Exlporer) plugin for Eclipse. The thing is that I dont know how to make a connection using a public key. I have file that I downloaded from my Amazon account, *.pem. But I don't see any forms or inputs for this, when I try to connect to my remote Linux server. It is just User-id and password. I also tried to open the public key using the system's text editor and copy everything to my password field, but it didn't worked. Pls help me
this was baking my noodle for a while too. you put the keys in a folder not in the RSE config but in the whole of eclipse
check this: http://siteadmin.gforge.inria.fr/eclipse-ssh.html
Not mentioned (at least in explicitly) is the fact that RSE (and for what I've seen, Eclipse in general) only seems to work with 1024 bit keys https://bugs.eclipse.org/bugs/show_bug.cgi?id=404714
I also had issues, because my privatekey was 2048, but I added a new key to authorized hosts and then I could connect.
I added my local computer's ~/.ssh/id_rsa.pub to the remote /home/ec2-user/.ssh/authorized_keys.
Then just set the user to connect in RSE to ec2-user when connecting.
Someone asked for root login. It works too: update /root/.ssh/authorized_keys, and edit /etc/ssh/sshd_config to allow root login:
#PermitRootLogin forced-commands-only
PubkeyAuthentication yes
Then reload the sshd daemon: service sshd restart
