That leads nicely into today&#8217;s topic&#8230; because modern computers tend not to have huge amounts of local storage. We generally don&#8217;t need it, because we store our files in the cloud, and only use the local drive as a cache. But what about when you&#8217;re importing large amounts of data (say video), and you want somewhere to stage it locally, with a little more space?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I was about to throw away an old NetGear ReadyNAS Duo unit (that&#8217;s been in disgrace ever since a disk failure taught me the hard way that RAID1 is not a backup&#8230;), but then I thought it might be useful to stage some video content, before moving it somewhere safer.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Accessing the ReadyNAS<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">First problem was knowing what IP address it had. I managed to find that using NetGear&#8217;s RAIDar utility. But, to change the IP address (or any other settings), I needed to use the admin console. And that gave me a problem: my browser refused to connect to the site, saying that the connection was not secure and that it uses an unsupported protocol.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Well, it&#8217;s better than a modern cutesey &#8220;Something went wrong&#8221; message. It gave me a clue as to the problem &#8211; SSL version or Cipher mismatch &#8211; sounds like out of date TLS. Indeed it is, and <a href=\"https:\/\/www.gaasen.com\/gaasen-blog\/nas-servers\/51-readynas\/50-loss-of-access-to-readynas-admin\">G\u00f8ran B. Aasen wrote about the challenge in March 2022<\/a>, along with a potential solution for certain ReadyNAS devices. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I&#8217;m not bothered about upgrading Apache to support TLS 1.2 &#8211; but I did still need to administer the device. I tried messing around with browser settings in Edge, Chrome and Firefox but had no luck. The transition period is over. TLS 1.0 is not supported at all. Then I had an idea&#8230; what if I installed an older browser version? And instead of installing it, what if I used a portable app version?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tada!<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"440\" src=\"https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/uploads\/image-3.png?resize=700%2C440&#038;ssl=1\" alt=\"Firefox 73.0.1 being used to access the ReadyNAS admin console\" class=\"wp-image-8987\" srcset=\"https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/uploads\/image-3-scaled.png?resize=1024%2C643&amp;ssl=1 1024w, https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/uploads\/image-3-scaled.png?resize=300%2C188&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/uploads\/image-3-scaled.png?resize=768%2C482&amp;ssl=1 768w, https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/uploads\/image-3-scaled.png?resize=1536%2C965&amp;ssl=1 1536w, https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/uploads\/image-3-scaled.png?resize=2048%2C1286&amp;ssl=1 2048w, https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/uploads\/image-3-scaled.png?resize=772%2C485&amp;ssl=1 772w, https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/uploads\/image-3-scaled.png?resize=1230%2C773&amp;ssl=1 1230w, https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/uploads\/image-3-scaled.png?resize=306%2C192&amp;ssl=1 306w, https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/uploads\/image-3-scaled.png?w=1400&amp;ssl=1 1400w, https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/uploads\/image-3-scaled.png?w=2100&amp;ssl=1 2100w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">So, here we go, <a href=\"https:\/\/sourceforge.net\/projects\/portableapps\/files\/Mozilla%20Firefox%2C%20Portable%20Ed.\/\">Firefox 73.0.1 from PortableApps, via SourceForge<\/a>.
