Generate a Solr Password Hash With a Shell Script

In 2017 I published a small Java utility for generating Solr password hashes, because I didn't like launching Solr with well-known credentials. I would've preferred doing it with just a shell script, but found myself unable to replicate the hash creation process with sha256sum.

A couple days ago user rmalchow contacted me on Github with a solution for that, which I want to share here.

Migration of SMB Shares

Share migration is a common (if not integral) part of a file server migration. If you just move the shares from one host to another host the process is pretty straightforward as described in MSKB article 125996:

  1. Export [HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares] on the old file server to a file:

    reg export HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares shares.reg
    
  2. Copy the file to the new file server and import it:

    reg import shares.reg
    
  3. Restart the Server service:

    net stop server && net start server
    
  4. Done.

Auditing Windows File ACLs

Sometimes you run into a situation where you need to determine the permissions on some directory tree. Be it to document or clean up permissions on the subdirectories of a share, to troubleshoot permission issues due to deleted accounts or groups, or whatever. Manually analyzing permissions is quite tedious, even when using standard tools like cacls or xcacls. The output of XCACLS.vbs isn't any better, but since it's a script, I considered modifying it to suit my needs … until I took an actual look at the script. I abondoned the thought afterwards.
