IJulia package installation - julia

Is there a way around the following error when trying to install IJulia package in Windows 7 Enterprise?
julia> Pkg.add("IJulia")
INFO: Initializing package repository C:\Users\user01\.julia\v0.4
INFO: Cloning METADATA from git://github.com/JuliaLang/METADATA.jl
fatal: unable to connect to github.com:
github.com[0: 192.30.252.129]: errno=No error
ERROR: failed process: Process(`git clone -q -b metadata-v2
git://github.com/JuliaLang/METADATA.jl METADATA`, ProcessExited(128))
[128] in run at process.jl:531
Thanks
If I need to use a proxy, how do I specify that in the Julia console?

Finally found the solution on Google Groups.
Basically, (assuming you already have git installed) I had to run each of the following 3 lines from the Windows 7 Powershell:
git config --global url."https://github.com/".insteadOf git://github.com/
git config --global http.proxy http://<proxyuser>:<proxypwd>#proxy.server.com:8080
git config --global https.proxy http://<proxyuser>:<proxypwd>#proxy.server.com:8080
where: <proxyuser> is your username, <proxypwd> is your password, proxy.server.com is your proxy address, and 8080 is the proxy port.
Hope this helps.

OpenVAS installation and running errors

I've installed Greenbone Security Assistant Version 9.0.1 (OpenVAS) by this instruction on my VirtualBox's Ubuntu 20.4.
sudo apt install postgresql
sudo add-apt-repository ppa:mrazavi/gvm
sudo apt install gvm
greenbone-nvt-sync
sudo greenbone-scapdata-sync
sudo greenbone-certdata-sync
Unfortunately, it does not works.
When I'm trying to create a task by Wizard, I have the task completed just in moment, with an empty log. And that's all.
I've tried three commands:
systemctl status ospd-openvas # scanner
systemctl status gvmd # manager
systemctl status gsad # web ui
Everything is okay, except ospd-openvas. The status is green and active, but there are some errors too:
Jul 20 15:00:27 alex-VirtualBox ospd-openvas[833]: OSPD - openvas:
ERROR: (ospd_openvas.daemon) Failed to create feed lock file
/var/run/ospd/feed-update.lock. [Errno 2] No such file or directory:
'/var/run/ospd/feed-update.lock'
From the error message it looks like the directory /var/run/ospd/ does not exist.
Create the directory and try to restart the service.
In ubuntu 20.04 /var/run points to /run which is a temporary file system. That means that if you create the directory /var/run/ospd manually, it will be gone after the next reboot. To fix it permanently (in case the missing directory is the issue), please refer to this post.
This may help some people with some of the issues I've been facing:
mkdir -p /var/run/ospd/
touch /var/run/ospd/feed-update.lock
chown gvm:gvm /var/run/ospd/feed-update.lock

Airflow installation issue on Windows 7

How to install Airflow on Windows 7? getting below error while installing it using pip install apache-airflow :

I wouldn't bother trying to install Airflow on windows, even after you install it successfully you cannot run the airflow script due to a dependency on the unix-only module pwd
You can run Airflow on Windows by using the Docker setup from puckel https://github.com/puckel/docker-airflow.
Use VirtualBox and Docker Toolbox(legacy) and setup a docker-machine on your Windows computer (docker-machine create -d virtualbox --virtualbox-cpu-count "2" --virtualbox-memory "2048" default)
make sure to fork puckels git repo underneath c:/Users/yourusername/documents otherwise mounting of DAGS won't work
You should now be able to spin up Airflow e.g. by using the celery-executor setup with docker compose -f docker-compose-CeleryExecutor.yml up -d
I have setup a environment where I develop the DAGs on Windows, test them within the dockercontainer and then push the Dockerimage to Linux to production. I have added a more detailed tutorial here.
Airflow cannot be installed on Windows within the standard command prompt.
You need to use bash and afterwards change the config:
How to run Airflow on Windows
Download the source of airflow from pypi:
https://pypi.org/project/airflow/#files
Unzip and edit setup.cfg, then go to the install_requires section and change the version of psutil with the following: 'psutil>=5.4.7',
Finally, run python setup.py install in the source directory

I've been working through the Hyperledger Composer tutorial (https://hyperledger.github.io/composer/tutorials/developer-guide.html) on an older Mac, running OS X Mavericks 10.9.5, which means I'm using Docker Toolbox instead of Docker for Mac. I encountered the same error message when deploying the sample Trading network .bna file on my local dev environment Fabric network.
Here is the command in Terminal:
$ composer network deploy -a my-network.bna -p hlfv1 -i PeerAdmin -s randomString -A admin -S
And here is the error log:
Error: Error trying deploy. Error: Error trying install composer runtime. Error: Connect Failed
In my case, it was because Docker Toolkit answers to on an IP address assigned when you start docker, instead of localhost, 127.0.0.1, etc.
If you are also using Docker Toolkit and are getting the same error, first find the docker IP number, which should be listed under the Docker Whale logo in Terminal when you started it, and then edit the following files (TextEdit should be fine), changing all references to localhost and 127.0.0.1 to the IP number (leave the ports, such as :7050, there):
fabric-tools/fabric-scripts/hlfv1/composer/configtx.yaml
fabric-tools/fabric-scripts/hlfv1/composer/docker-compose.yml
fabric-tools/fabric-scripts/hlfv1/createComposerProfile.sh
fabric-tools/fabric-scripts/hlfv1/createPeerAdminCard.sh
Then, back in Terminal, navigate back to fabric-tools, and if Fabric is already started, stop it, and then recreate the Composer Profile, as documented:
$ ./stopFabric.sh
$ ./createComposerProfile.sh
The log should now show the Docker Toolkit IP for the orderers, CA and peers. Now restart Fabric:
$ ./startFabric.sh
Navigate back to fabric-tools/my-network/dist and re-run the compose command, and if all goes well, it should connect properly.
Is your Fabric running? What is the output of docker ps?
Try doing the next:
Pick a directory that you want and install Hyperledger Fabric and Hyperledger Composer Playground running:
curl -sSL https://hyperledger.github.io/composer/install-hlfv1.sh | bash
Then run your command.
Try the code below:
$composer runtime install -c PeerAdmin#hlfv1 -n basic
$composer network deploy -a basic.bna -A admin -S adminpw -c PeerAdmin#hlfv1 -f admincard

openstack deployment using kolla erroring out

I have followed below document to deploy openstack using kolla and I have built all the docker images successfully. I am following this guide for all-in-one installation.
http://docs.openstack.org/developer/kolla/quickstart.html
I have cloned stable/liberty branch.
But while issuing kolla-ansible deploy getting below error.
:# kolla-ansible deploy
Deploying Playbook : ansible-playbook -i /usr/local/share/kolla/ansible/inventory/all-in-one -e #/etc/kolla/globals.yml -e #/etc/kolla/passwords.yml /usr/local/share/kolla/ansible/site.yml

I have searched a lot about this error but could not find anything, any idea about this error?
Please make sure you have right version of ansible on your deployment node. It should expect version >1.9.4 but < 2.0

I've found a lot about the error stdin: is not a tty but none of them make much sense to me.
Open your /etc/sudoers file, find the line that says Defaults requiretty, and change it to Defaults !requiretty.
This will disable the tty requirement globally.
