| AWS: Restrict external access to Database but allow ECS task to access Posted: 27 Mar 2022 01:23 AM PDT I'm not great at network administration so I need some help to do something really basic on AWS. Basically, I have a RDS database on a vpc, let's call it VPC1. The database is also associated with VPC security group "Default: sg1" I have a API server that needs to access the Database running as a docker image (service) using ECS. This API server is associated with a load balancer on the same VPC ID VPC1. The task has external IP XXX.XXX.XXX.XXX and internal IP YYY.YYY.YYY.YYY All I want to do is allow the ECS service to access the database, but disable all other external access. I've tried the following:
None of these seem to work. What am I missing here? |

| The access to shared directory using DFS is very slow Posted: 27 Mar 2022 02:14 AM PDT I have an Active Directory with 1 DC and 1 DFS deployed on hyper-v VM on a certain machine X. The DFS consists of several shared folders from machine X and folders from machine Z. When I try to access the DFS using network drive all works fine for machine Z folders. But I have some problems with folders from machine X. The access to machine X folders is very slow. Sometimes it takes several minutes to open even small file. When I try to upload files to machine X folders all works fine but the download speed is very small. The upload speed is about tens of Mb/s but download speed ~ 100 kb. Any help is appreciated. |

| AWS "No credentials specified" even when EC2 IAM policy applied Posted: 27 Mar 2022 12:07 AM PDT This is an odd issue which we can't find a solution for. On AWS, we are running Microsoft Remote Desktop Services on Windows Server 2019. All servers are joined to an AWS AD Directory Services domain. The RDC Host Servers have an IAM policy that allows all actions to S3. We have two users in the domain, both assigned to the same group - the default group "Domain Users". When we log in to a Session Host with one user, we have no problem calling "Get-S3Object". But when we log in with the second user and call "Get-S3Object", we get "No credentials specified or obtained from persisted/shell defaults" - permissions should be given by the IAM policy attached to the EC2 which works for the first user. To fix the problem, we have found that if we delete the second users' Windows profile, then the next time the second user logs in, they are given a TEMP profile and they are able to call "Get-S3Object", so clearly there is a problem with the user profile. The Windows Servers are practically a vanilla instance and it's strange that deleting the User's profile fixes the issue... We have also created a new domain user which had the same problem on one Session Host but not on another. It's a very random issue. Has anyone else come across this problem? What can be causing this to happen? |
| Posted: 27 Mar 2022 02:05 AM PDT I have to setup haproxy with agent-check, the backend servers reporting themselves their weight ("28%" for example) over http. Seems like haproxy can't speak http with it's agents, which seems weird. Is there no way to do it ? I've tried this : Which may or may not work, I actually have no idea. Is there any way to tell if the agent-check are succeeding or not ? The statistics page doesn't seem to change whether the url is valid or not. I'm guessing it's not working, because haproxy must be expecting just the value, not any of the http around it. |
| Connect MongoDB Compas to GCP Ubuntu VM Posted: 26 Mar 2022 11:01 PM PDT I am a little lost on how should I host MongoDB on Ubuntu VM. I barely worked with Ubuntu before so I struggle to understand a lot of aspects. I followed guide: https://docs.mongodb.com/tutorials/install-mongodb-on-ubuntu/ And everything seemed to work in GCP VM SSH console. I was able to login to DB with admin login and password. But I don't understand why I cannot connect to it from external resources and how to debug the issue. I am trying to access DB with VM external IP, provided by GCP compute engine, I used existing authentication information but it doesn't work, all I get is this error after around a minute of waiting:
Is there any guide or advice to help me understand what exactly is wrong? I am lost and don't know what to check to even find the issue. |
| Create screen session in background only if it doesn't already exist Posted: 27 Mar 2022 03:00 AM PDT How can i create a This creates a screen named name in detached mode but will create duplicates This creates a screen only if it doesn't exist but not detached How do i combine both? I need to create multiple screens in a batch file so reattaching is not convenient.

| Posted: 27 Mar 2022 03:03 AM PDT So I have the following scenario - two servers, one is Web server, another is a Backup server. Both running Windows Server 2012 R2 I have a mapped drive on Web referencing Backup I have a VHD I created on the Map drive, physically located on Backup that is being used by Web in order for Windows Server Backup to do nightly images to this VHD. The idea is to have the images physically stored on the Backup server, but performed from the Web server. I have this VHD showing as a real drive in My PC on Web. I'd like to mount this VHD as Read Only on the Backup server so I can take a peak every now and then to make sure the backups are showing up / access if necessary. The problem is when I try to mount the VHD on the Backup as Read Only I receive "The process cannot access the file because it is being used by another process" I'm suspecting they are saying this because its mounted on Web. I'm wondering if there is any way I can accomplish what i'm hoping to accomplish or if its not possible. FYI - HyperV/VM backups aren't a possibility in this scenario. |
| Squid Proxy: 400 Bad Request when "%25" (Percent Sign) in URL Posted: 27 Mar 2022 02:05 AM PDT I have a squid proxy that works well except for this issue: If a URL has a Example URL: http://www.amazon.com/25%25-Percent-Off-Stickers-Adhesive/dp/B00J0IBJ0S/ Log:
I'm not sure if this is a bug or a configuration error. I have a round robin setup as shown above. Here is the output of
(It's an Ubuntu 12.04.5 LTS server) The hack with this URL would simply be to have something strip out the The URL works fine when not going through the proxy. Thanks for any ideas, I'm willing to provide more config info. |
