Seems like the optional dependency, sl-blip, is the problem. It seems to not be on the interwebs anymore. Any help would be greatly appreciated
BTW, there is no proxy at play here.

In the end, I removed Yarn from the equation and did an npm update and the problem was gone.

Elastic-APM Invalid index name [_license]

We are trying to get elastic-apm install (for now on our development systems).
According to Homebrew, we have the latest elasticsearch-oss (7.10.2), kibana-oss (7.10.2) and today installed apm-server-oss (which is at version 7.13.0).
Running a apm-server test output we get:
% apm-server test output
elasticsearch: http://localhost:9200...
parse url... OK
connection...
parse host... OK
dns lookup... OK
addresses: ::1, 127.0.0.1
dial up... OK
TLS... WARN secure connection disabled
talk to server... ERROR Connection marked as failed because the onConnect callback failed: could not connect to a compatible version of Elasticsearch: 400 Bad Request: {"error":{"root_cause":[{"type":"invalid_index_name_exception","reason":"Invalid index name [_license], must not start with '_'.","index_uuid":"_na_","index":"_license"}],"type":"invalid_index_name_exception","reason":"Invalid index name [_license], must not start with '_'.","index_uuid":"_na_","index":"_license"},"status":400}
Because the documentation on getting APM going is somewhat obtuse, perhaps this is a configuration issue. But how to investigate further?
Is the solution to install an earlier version of apm-server? If so....how to actually do that with homebrew?
I had the same issue when using non-oss versions. Managed to fix this by upgrading ElasticSearch and Kibana to 7.13.2.

When these started occurring we could no longer manage any aspects of the Hadoop cluster through Ambari. All the services showed little yellow question marks and said "heartbeat lost".
Multiple restarts would not allow us to resume Ambari, and ultimately regain control our cluster.
This issue turned out to be due to the server's inability to deal with TLSv1.1 certificates when it was attempting to connect to the CA service on port 8440.
We noticed that the service was in fact running:
$ netstat -tapn|grep 8440
tcp 0 0 0.0.0.0:8440 0.0.0.0:* LISTEN 1203/java
But curl's to this would fail, unless we disabled TLS checks via the --insecure switch. This was our first clue that it appeared to be something related to TLS.
Further investigations led us to NetUtil.py (part of Ambari) which seemed OK. Other leads include:
$ cat /etc/ambari-agent/conf/ambari-agent.ini
...
[security]
ssl_verify_cert = 0
...
And this:
$ grep -E '\[https|verify' /etc/python/cert-verification.cfg
[https]
#verify=platform_default
verify=disable
None of which worked. What did ultimately work is this, Forcing ambari-agent to use TLSv1.2 vs. TLS1.1:
$ grep -E "\[security|force" /etc/ambari-agent/conf/ambari-agent.ini
[security]
force_https_protocol=PROTOCOL_TLSv1_2
And then restarting, ambari-agent restart.
I was able to piece this all together using wisps of hints scattered all over the Internet. I'm putting this here in the hopes it will help any other poor souls that have this happen to their Hadoop/Hortonworks cluster.

Why did this happen?
Further debugging/digging I found this thread titled: Disabling TLSv1 & TLS1.1 - Enabling TLSv1.2. It's apparently mandatory that you now configure your Ambari Agent's to use TLSv1.2.

Error while running berks install

I have a windows instance which on top of that I'm running a windows docker container. On the instance itself I'm succeed to execute berks vendor/install without any issues. However on a windows docker container running on that machine it doesn't work and throws me a timeout error.
The error wasn't clear enough so I decided to execute librarian-chef install and got some more output. It appears that there is something related to SSL connection.
I tried several things after a long research during last couple days but still getting same error.

I have the same error; this only happens when I am logged into my company's network. When I am on the internet directly, there is no issue; so I suspect it is a problem with a proxy server, or something in my company's network.
Slava: I sincerely hope that this is the same kind of problem; I just did not want to duplicate the question; please let me know and I can create a different item.
When I get this problem, the error message is:
>>>>>> ------Exception-------
>>>>>> Class: Kitchen::ActionFailed
>>>>>> Message: 1 actions failed.
>>>>>> Failed to complete #converge action: [Error connecting to https://supermarket.chef.io/universe - Failed to open TCP connection to supermarket.chef.io:443 (getaddrinfo: No address associated with hostname)] on default-centos-67
>>>>>> ----------------------
>>>>>> Please see .kitchen/logs/kitchen.log for more details
>>>>>> Also try running `kitchen diagnose --all` for configuration
in my case, the web proxy needed to be set properly.

how to fix this ???
You have to install tor apt-get install tor and then run tor in a terminal, after that you can do sqlmap --tor --tor-type socks5 --tor-port=9050 --check-tor -u http://www.target.com/abc.php?cat=50 to execute with tor.
I had a very similar issue the way that I solved it was to use proxychains and edit the proxychains conf file to route requests through tor. It is easy enough to do
I do not have kali open but you can find the file by opening the terminal and typing
locate proxychains.conf
