Re: [IBMiOSS] Unable to establish SSL connection. received when using wget

Hi Arco

I believe it turns out that direct internet access from IBM i's is not available, hence the failure. We have to use other means, and those have been successful.

Thanks all for your thoughts!

Hi Vern,

From a security perspective this might be a bad advice, but what if you try
to execute wget without ssl certificate verification?

wget --no-check-certificate <your url>

Hi Bryan

Thanks for your reply. I do appreciate the links, they confirm that I've
been looking in the right places for Kafka.

The steps I followed were those in the Kafka section at
ibm-oss-docs.readthedocs.io, which is one of the links in the resources
page at github. Those resources, however, don't deal with the error I
get when using wget - this is that error -

-bash-5.2$ wgethttps://

i recall reading this about kafka.
https://ibmi-oss-docs.readthedocs.io/en/latest/kafka/README.html


for most of it you should look and see what is available in the
repositories
https://ibmi-oss-docs.readthedocs.io/en/latest/yum/IBM_REPOS.html

those are a little long in the tooth, but a great place to start.

i’m certain that other will chime in as well.

Well, I'm finally dipping my toes into these waters. I'm going to be
working with kafka where I am now. Am using Mobaxterm for an SSH
terminal, using bash.

I am following the directions and am at the point of running this:

wgethttps://dlcdn.apache.org/kafka/3.0.1/kafka_2.13-3.0.1.tgz

That's the instruction at ibmi-oss-docs for kafka. That URL is not
valid, it's an old version, and that's OK. So I went to the
Apache.org<http://Apache.org> site, found a downloads page, so the
command I'm using is actually this -

wgethttps://downloads.apache.org/kafka/4.0.0/kafka_2.13-4.0.0.tgz

So when I execute that, I receive this

-bash-5.2$
wgethttps://downloads.apache.org/kafka/4.0.0/kafka_2.13-4.00.tgz

I appreciate guidance here on this new venture!
