Is it impossible to mount an Azure File Share on an Azure VM?

28 January 2026 @ 3:20 pm

I am trying to set up a Windows 11 Azure Virtual Desktop that has access to an Azure file share via a mapped drive letter. I created the File Share and can connect to it just fine from my own workstation running Windows 11, using net use S: "\\mystorageaccount.file.core.windows.net\sharename", or New-PSDrive -Name S -PSProvider FileSystem -Root "\\mystorageaccount.file.core.windows.net\sharename" or New-SMBMapping However, I get System error 67 any time I try to mount the exact same path from any Azure machine. The hostname is found by nslookup and Test-Connection -ComputerName mystorageaccount.file.core.windows.net -Port 445 I also created a Windows Server 2022 VM to try and replicate it with an older OS, and it was exactly the same. I am authenticating using the Storage Account Key. The File Share is in the same region as the VM. I don't have any Azure Firewalls

Nginx continues to write to logrotate rotated file

28 January 2026 @ 9:21 am

I have Nginx running in Docker on Ubuntu 22.04 To rotate logs, I use Logrotate 3.19 After the upgrade from Ubuntu 20.04 to 22.04, Nginx stoped writing to new access.log after rotation. Manually running logrotate would run without errors and Nginx starts writing to new file. I have no idea where to look for problem here. Nginx just writes 8Gb to access.log.1 until there is no space left on device. Logrotate config file is default, not altered: /var/log/nginx/*.log { daily missingok rotate 14 compress delaycompress notifempty create 0640 www-data adm sharedscripts prerotate if [ -d /etc/logrotate.d/httpd-prerotate ]; then \ run-parts /etc/logrotate.d/httpd-prerotate; \ fi \ endscript postrotate invoke-rc.d nginx rotate >/dev/null 2>&1 endscript }

Windows Domain Users Unable to change password with Ctrl+Alt+Del [duplicate]

27 January 2026 @ 5:20 pm

I'm making this post just to make the solution more visible, as I had to dig around multiple answers and reddit posts without finding a resolution. Our windows domain had an issue where users could not change their passwords via Ctrl+Alt+Del. Our group policy had a minimum password age of 0, and complexity requirements enabled. We did not have any Fine-Grained password policies in place. When attempting to change the password, the error pop up stated "Unable to update the password. The value provided for the new password does not meet the length, complexity, or history requirements of the machine or domain. Try increasing the length of your password, along with including upper and lowercase letters, numbers, and symbols." The new password contained special characters, numbers, and lowercase/uppercase letters. When our windows admins would set "User needs to change password on next login" via ADUC for users, they would be prompted with

ssh_host_dsa_key is not present on debian 13

27 January 2026 @ 3:31 pm

I created a new debian 13 server, and proftpd is failing because the file '/etc/ssh/ssh_host_dsa_key' does not exist. proftpd has lines with this content: SFTPHostKey /etc/ssh/ssh_host_rsa_key SFTPHostKey /etc/ssh/ssh_host_dsa_key The error message for proftpd: 2026-01-27 16:04:26,720 example proftpd[42786]: fatal: SFTPHostKey: unable to check '/etc/ssh/ssh_host_dsa_key': No such file or directory on line 13 of '/etc/proftpd/conf.d/sftpd.conf' I looked into debian bugs to see if there's mention of removing the ssh_host_dsa_key file, but I couldn't find anything. I will remove the line with the error and stay with the rsa key, but I'd like to find the cause.

Dell PowerEdge C6400 with Broadcom BCM57416 on a Proxmox host is recognised, but the ports don't go up [closed]

27 January 2026 @ 1:12 pm

I installed proxmox on a DELL PowerEdge C6400 with a Broadcom BCM57416, using the driver bnxt-en. The ethernet controller is recognized with lspci | grep -i ethernet, and the interfaces are configured but are DOWN. The LEDs do not turn on when connected to the cable, but I'm sure it's not the cable because I exchanged the cables with the iDRAC port and both work correctly. Running ethtool -t nic0 fails at Link test (online) and Ext loopback test (offline). I looked at dmesg and journalctl but I didn't find meaningful information.

Getting attacked 3 times in a row on fresh DigitalOcean droplets - what am I missing? [closed]

27 January 2026 @ 5:51 am

I am completely lost now and need help figuring out what's going on. My DigitalOcean droplets keep getting compromised and used for DDoS attacks. This is the third time in a row on completely fresh builds. Each time I destroy the droplet, start from scratch, add more security, and within a day it happens again. Could there be something in my application code itself that's being exploited? Could my GitHub Actions deployment pipeline be compromised? Is there something at the DigitalOcean account level that could be the issue? What am I fundamentally missing here? i am running - Node.js application with Docker containers, PostgreSQL and Redis, Nginx as reverse proxy, Deploying via GitHub Actions Security measures I've implemented (after getting burned twice already): SSH: Disabled password auth, disabled root login, using ED25519 keys only, changed default port, a

Shibboleth PEM files and Tomcat

27 January 2026 @ 1:57 am

This is a Shibboleth question regarding PEM files and Tomcat. I noticed within the Shibboleth Windows installation, there are some PEM files within the ...\shibboleth-sp\etc\shibboleth dir. Do I need to use the Java JDK keytool.exe utility and add these to my keystore for Shibboleth to work properly with Tomcat? EXAMPLE: keytool -import -trustcacerts -file c:\opt\shibboleth-sp\etc\shibboleth\sp-encrypt-cert.pem -keystore cacerts keytool -import -trustcacerts -file c:\opt\shibboleth-sp\etc\shibboleth\sp-encrypt-key.pem -keystore cacerts keytool -import -trustcacerts -file c:\opt\shibboleth-sp\etc\shibboleth\sp-signing-cert.pem -keystore cacerts keytool -import -trustcacerts -file c:\opt\shibboleth-sp\etc\shibboleth\sp-signing-key.pem -keystore cacerts

WSUS importing updates fails

27 January 2026 @ 12:43 am

We have physical separation between the internal and external networks, with WSUS servers on both networks. Updates are transferred from the external network to the internal network server using a combination of copying and overwriting the WSUS content and using the wsusutil export/import commands. This process has been working correctly, but recently a strange problem has occurred. Previously, after copying the patch files and metadata to the internal server and the server stabilized, the WSUS overview page showed the status as Download Status: Updates requiring files: 0. Recently it changed to: Download Status: Updates requiring files: 1765, Downloaded 108.34MB, Total 154,393.54MB After two weeks, the screen remains unchanged. Running wsusutil.exe reset several times did not resolve the issue. How can we solve this problem?

How can I visualize the hierarchy of all Azure resource groups, resources and models in my Azure subscription?

26 January 2026 @ 11:59 pm

I am currently managing a complex Azure subscription that contains a large number of Resource Groups, Resources and various models (mostly AI models/deployments). Navigating through the portal list-view is becoming difficult. I am looking for a way to visualize these components in a hierarchical or graphical representation. How can I visualize the hierarchy of all Azure resource groups, resources and models in my Azure subscription?
