Save kerberos password in keychain for use with kinit on MacOS (was OS X) for use with network drives

Image
I work for a company that uses and Active Directory domain for the internal network. Therefore, kerberos authentication is supported. MacOS also supports kerberos authentication, so I can replicate most of the single sign-on experience on my Mac. I wrote a simple shell script to get a kerberos ticket-granting ticket and mount the network drives: #! /bin/bash # get the local IP address theIP = ` /sbin/ifconfig | /usr/bin/grep "inet 10" | /usr/bin/grep -v inet6 | /usr/bin/cut -d " " -f2 | /usr/bin/cut -d . -f1` # if IP address starts with 10 then I am probably on work's internal network if [ $theIP -eq 10 ] ; then /usr/bin/kinit -f --enterprise --canonicalize username@company . com@COMPANY . COM /usr/bin/open 'smb://server.company.com/share' fi To make this script really useful, I save my password securely in MacOS's keychain so that kinit can grab it automatically. I use the following command in the terminal:  ...

Samba in Debian 13 with WS-Discovery working properly in Windows 11 without compromising security

Recently, a buddy asked me to help him configure a linux machine with a shared folder that would work on MacOS and Windows 10. Everything work in MacOS without issues. The trouble came when trying to access the share in Windows 10. After a bunch of research, I learned that Windows 10 has a new way of discovering computers on the network and needs to be told in advance what credentials to use.   Samba Configuration Below is what I did to get it all working without compromising security I used this smb.conf file. There is a bunch of stuff to make the Mac clients play nicely and 3 lines to make it work properly with Windows 10/11.  After some testing, I discovered that the share name should NOT be the same as the shared folder name in the path. [global]    workgroup = WORKGROUP    log file = /var/log/samba/log.%m    max log size = 1000    logging = file    panic action = /usr/share/samba/panic-action %d    server r...

Convert WebVTT file to SRT format (VTT to SRT)

Lately, I have been creating lots of how-to videos for my colleagues at work.  I like to include subtitles since some people may prefer to read the words I am saying.  We use Microsoft Stream to host the videos since it is part of our Office 365 subscription. One of the great things about Microsoft Stream is that it will automatically generate captions (subtitles) from the audio in the video file.  You can edit the captions right in the web interface as you watch the video.  Microsoft did a great job on this user experience. Today, I needed to burn the subtitles into the video because of limitations of the customers computers.    Handbrake does this well, but it does not understand the WebVTT format.  There are several online converters, but I do not like giving my content to unknown internet services, so I starting learning about the difference between the formats.  JBI Studios have a very helpful explanation about the differences.  I w...
