QUESTION
Our Security Dept requirement on egress traffic is very strict: Each app inside POD must go through some proxy with mTLS authentication (app-proxy) using dedicated cert for the app. They're suggesting using squid with tunneling to cope with double mTLS (one for proxy and the other one for the specific traffic app-server), but then we forced the app to be ssl-aware. Istio can come in and do the job but using out-of-the-box ISTIO_MUTUAL mode (between istio-proxy and egress gateway) is not the case for us.
So, I've tried using example Configure mutual TLS origination for egress traffic by modifying it a bit as follows (changes marked with #- and #+):
...ANSWER
Answered 2021-Jun-09 at 08:40OK, finally I've solved it. The key point here is the part of DestinationRule spec, which says:
- credentialName -> NOTE: This field is currently applicable only at gateways. Sidecars will continue to use the certificate paths.
So I've modified the following manifests:
client deployment of sleep.yml (to mount certs)

QUESTION
I'm trying to publish MQTT message to AWS IoT Core from Lambda on a different account.
Less assume that Account A is the one with the IoT core and account B is the one that has the lambda function.
On Account A: I created the following role type 'Another AWS account' using the account ID of B with the AWSIoTDataAccess policies:
...ANSWER
Answered 2021-Jun-02 at 09:14To get the cross account data interaction we need to follow the below steps:
Create a role in the Account from/to where you want to push/pull data from ( in your example Account A i.e. with IOT Core)
Create a trust for that role
Using "sts:AssumeRole" within Account B ( you are using lambda) to get the access/privilege's assigned with role in account A.
In you code I do not see the "sts:AssumeRole" and probably that is what causing the issue. You can refer to How can I configure a Lambda function to assume a role from another AWS account?
QUESTION
I have an AWS classic load balancer. Here are my listeners :
The AWS classic load balancer
is doing tls termination, and redirecting the traffic to port 30925
of my nodes
The process listening on port 30925
is an istio gateway, redirecting traffic afterwards based on the SNI
of the request
However, the AWS classic load balancer
doesn't seems to keep the SNI
of the request after tls termination
Is there any documentation regarding the behavior of the load balancer in that situation?
I found a couple of links talking about SNI
(here for example), but it's only talking about the load balancer itself handling the routing of the SNI
ANSWER
Answered 2021-May-31 at 10:05Based on the comments.
If you terminate SSL on the load balancer (LB), SSL-related information is not carried over to your targets. To ensure full SSL-forwarding to your targets, you have to use TCP listener. This way your targets will be responsible for handling SSL, and subsequently will be able to custom process it.

Answered 2021-May-14 at 17:30get_https3 like many similar functions ultimately ends up in https_cat where the SSL context setup and the SSL handshake are done. Unfortunately, setting the server_name
extension (SNI) is not done in this really old part of the code, which comes from a time where SNI wasn't that essentially for using HTTPS as it is today.

QUESTION
I am trying to set TCP idleTimeout via an Envoy Filter, so that outbound connections external domain some.app.com
will be terminated if they are idle for 5s:
ANSWER
Answered 2021-May-11 at 09:41This is a community wiki answer. Feel free to expand it.
As already discussed in the comments, the EnvoyFilter
was not yet supported in Istio version 1.2 and actually that version is no longer in support since Dec 2019.
I strongly recommend upgrading to the latest Istio and Envoy versions. Also, after you upgrade please notice that the filter name you want to use was deprecated and replaced. You should now use envoy.filters.network.tcp_proxy
instead of envoy.tcp_proxy
.
Please remember that things are getting deprecated for a reason and keeping the old versions will sooner or later bring you more trouble. Try to keep things more up-to-date.
More details can be found in the latest docs.

ANSWER
Answered 2021-Apr-21 at 11:12I think to update databases you need to create a database first. If you have not installed SQL Server I recommend you to install SQL Server from microsoft store at first.
- To create a database at SQL Server click on 'view' at toolbar select 'SQL Server object explorer'.
- that will open a window at the left-Up corner, there will be a SQL Server at the top of that move pointer there will be given Object Explorer or SQL Server object explorer; click on that.
- Now the structure of that will be changed open SQL Server then click on open any localdb database something is given then There will have databases folder.
- Right click on databases and create a new database and then create a table inside that database.
Another way you can do that.
- Install microsoft sql server manager studio.
- Then connect to sql server engine.
- Right click on database and create a database and then create table.
then again try your commands to update the database. I hope that will help you.
QUESTION
This question is closely related to my other question: Python `urllib3`: sudden "certificate verify failed: certificate has expired" error.
For some reason it seems like my attempts at provide the correct hostname for SNI do not succeed. This manifested first in the proxy in the linked question, as without properly working SNI it can't successfully validate certificates. Then as I went onto debugging the issue using an installation of OpenSSL (separate from Python and the system) it also displays the same signs. I decided to see if at least Node.js correctly works with SNI using this script, but no luck:
...ANSWER
Answered 2021-Apr-21 at 12:49Turned out NetLimiter 4 is to blame. When weeding out the causes I did initially suspect it, but the problem persisted through a brief time I turned the system service off, so I figured it must be something else. But I didn't know back then it also installs a driver that keeps working independently of the service. Once I realized that (took me a long time admittedly) I fully uninstalled the program and now the problem is gone.
