QUESTION
I'm trying to connect a Go application with postgresql.
The app import postgresql driver:
...ANSWER
Answered 2021-Mar-07 at 16:58The first problem is a typo in the connection string: postgresql://user:user@172.20.0.1:5432/lcp?sslmode=disable
. In Go code it should be postgres://user:user@172.20.0.1:5432/lcp?sslmode=disable
.
We also need to pass the full connection string as the second argument to sql.Open
. For now, the dbFromURI
function returns user:user@172.20.0.1:5432/lcp?sslmode=disable
, but we need postgres://user:user@172.20.0.1:5432/lcp?sslmode=disable
, because pq is waiting for this prefix to parse it.
After fixing this, I was able to establish a connection using a minimal postgres client based on your code.
To try this yourself, start the server with the following command:
QUESTION
I am trying to import module OpenSSHUtils under Win 10, PS 5.1.
The latest version (whatever the number) is apparently not available.
...ANSWER
Answered 2020-Jul-15 at 19:01In short, OpenSSHUtils has been deprecated by Microsoft (as you've indicated) and is no longer required. It is not recommended that you attempt to install this.
If you explain to us what feature from OpenSSHUtils you require, we can help you with a workaround.
- Most likely you'll be able to find what you're looking for on the Windows OpenSSH Github Repo
Furthermore, this GitHub comment references most of the open issues regarding the deprecation. https://github.com/MicrosoftDocs/windowsserverdocs/issues/3400#issuecomment-658249949
Manual InstallationThis is not recommended, but I'm explaining it to give you a better understanding of custom modules. This can also be used if Install-Module
is not available on your version of PowerShell.
Where can I find the nuget package?
You've actually already linked it (https://www.powershellgallery.com/packages/OpenSSHUtils/1.0.0.1). If you click on "Manual Download" you'll be able to manually download it.
Is having the psd1 and psm1 equivalent to having the nuget?
The psd1 is all you need to be able to use the module. You'll need to manually install it.
- type
$env:PSModulePath
to determine the locations PowerShell looks for modules on your system. The recommended location is C:\Windows\system32\WindowsPowerShell\v1.0\Modules\ for system-wide use.

Use this guide installed FreeIPA with SSL: https://www.howtoforge.com/how-to-install-freeipa-server-on-centos-7/
...ANSWER
Answered 2020-Apr-27 at 07:40I don't see how this question is related to programming, maybe move it to ServerFault.
And it's not clear what you want to do exactly. You don't want to install an embedded CA within the IPA Server, but it's unclear if you're going to use an external CA or no CA at all. In the first case this means the IPA Server would still automatically update the certificates, while the second case means you would update yourself when it is necessary.
The best entry point is the Linux Domain Identity, Authentication, and Policy Guide
If you're not going to use any CA at all, see section 2.3.6 :

QUESTION
I wanted to avoid using Aerospike clients (e.g. for Python) and delete records from a set using native asinfo command 'truncate' as it allows to do it quickly. But after I restarted Aerospike all deleted records were back. I saw this aerospike: delete all record in a set but it doesn't answer my question. Neither does this page from AS docs. It says, that a tombstone should be written after a durable delete, do I have to create it manually or are there some other ways?
UPD: Thanks to @kporter who provided the accepted answer below I was able to look into differences between Community and Enterprise edition of Aerospike and found more information on the problem, some may find it helpful as well:
- Persisted Delete [Community Edition]
- This answer and the whole discussion from AS forum
- And this thread
If I understood all of it correctly the best way to get your records deleted completely in CE is to ensure that they have right TTL and can expire naturally. And if for some reason you have a lot of old records without TTL as in my case, you can issue truncate command via asinfo and do not restart AS server until data on SSD is eventually overwritten. Or just truncate sets with old records on every restart.
Also I wonder if it is possible to wipe AS storage completely and then restore it from a backup of already truncated data as an emergency measure?
UPD1: So, I was able to wipe SSD with Aerospike storage and restore only needed records from a backup. Here is how I did it:
- Firstly, you need to remove old records from sets via asinfo and truncate command, links to docs are above
- Then backup namespaces you want to save with asbackup
- Stop your AS server, mine was in Docker container, so I just stopped said container
- Zero out the disk that is used as AS storage, mine was /dev/sdb
- Create necessary partitions on this disk
- Start AS server
- Restore data from the backup using arestore
Useful links: how to remove and clean up an aerospike server installation, AS docs on SSD setup
I am not sure if it is a good solution for large production setups but it worked as intended in my case with only one AS node and an opportunity to stop it for a while. This way I was able to reduce the size of data in my AS from 160Gb to 11Gb and because of that my server now fully restarts only in half an hour instead of approximately eight hours as before.
...ANSWER
Answered 2020-Mar-10 at 18:31You can find more information about truncating a set here: https://www.aerospike.com/docs/operations/manage/sets/
As mentioned there, truncation is not durable in Aerospike Community.
In the Enterprise Edition, truncation is durable and preserves record deletions through a cold-restart. In the Community Edition, similar to record deletes, records in previously truncated sets are not durable and deletes can return through a cold-start.

QUESTION
so I have a problem getting keycloak 3.2.1 to work behind kong (0.10.3), a reverse proxy based on nginx.
Scenario is:
I call keycloak via my gateway-route via https://{gateway}/auth
and it shows me the entrypoint with keycloak logo, link to admin console etc. - so far so good.
But when clicking on administration console -> calling https://{gateway}/auth/admin/master/console/
, keycloak tries to load its css/js via http (see screenie below), which my browser blocks because mixed content.
I searched around and found this thread: keycloak apache server configuration with 'Mixed Content' problems which lead to this github repo: https://github.com/dukecon/keycloak_postgres_https
From there on, I tried to integrate its' cli into my dockerfile with success (did not change the files' contents, just copied them into my repo and add/run them from dockerfile). This is my dockerfile right now:
...ANSWER
Answered 2017-Nov-10 at 18:25This sounds somehow like a duplicate of Keycloak Docker behind loadbalancer with https fails
Set the request headers X-Forwarded-For
and X-Forwarded-Proto
in nginx. Then you have to configure Keycloak (Wildfly, Undertow) to work together with the SSL terminating reverse proxy (aka load balancer). See http://www.keycloak.org/docs/latest/server_installation/index.html#_setting-up-a-load-balancer-or-proxy for a detailed description.
The point is that nginx is terminating SSL and is forwarding the requests to Keycloak as pure http. Therefore Keycloak/Wildfly must be told that the incoming http requests from nginx must be handled like they were https.
