@egc
Kudos to you egc... ssh key generator would make our lives much easier...



@the-joker
sometimes I get this message (when GUI goes black-white):

Code:
Failed to load resource: net::ERR_SOCKET_NOT_CONNECTED (http://192.168.1.1/style/cyan/style.css)


explenation is this:

Code:
Audit usage of navigator.userAgent, navigator.appVersion, and navigator.platform



A page or script is accessing at least one of navigator.userAgent, navigator.appVersion, and naviga
or.platform. Starting in Chrome 101, the amount of information available in the User Agent string
will be reduced.
To fix this issue, replace the usage of navigator.userAgent, navigator.appVersion, and navigator.pl
tform with feature detection, progressive enhancement, or migrate to navigator.userAgentData.
Note that for performance reasons, only the first access to one of the properties is shown.


I don't know nothing about coding, and don't know of this is helpfull at all but just wanted to report it... I use google chrome Version 106.0.5249.119 (Official Build) (64-bit) on Linux 5.18 kernel...

Well it was your idea in the beginning Smile
But has taken far too long and I am still researching how to get it right in a user friendly manner, it is working though, key is added or replaced on the router and downloaded to your PC/client.

Generating an ed25519 key pair takes 20ms on my Raspberry 4

Code:
time ssh-keygen -t ed25519 -f /tmp/test -N ""
Generating public/private ed25519 key pair.
Your identification has been saved in /tmp/test
Your public key has been saved in /tmp/test.pub
The key fingerprint is:
SHA256:q7A4y/MFCaRSOwM8DIwKgbbqNjX7kJpSJpimrI7JsG0 user@raspberry4
The key's randomart image is:

Nothing to see here - move along


I just wanted to say that the speed of even old routers would certainly not be a problem if you use something other than RSA.

even if the processor is 10x slower it would only be 200ms

yes I know !! is currently not available
but you can't mention it often enough - maybe the availability will change sometime in the future

The defaults in dropbear need to be changed, then.

1) ED25519 and no other options would still probably take space that would not be viable across the board for all supported devices. You would have to rip the heart out of DD-WRT to accommodate it, and that ain't happenin' most likely.

2) It's not about key generation time, it's about key authentication time, which ED25519 is supposed to be faster, right?

3) It's already been discussed that speed over security is still a talking point here and that RSA is still more tried and true.

4) Most importantly, I'm not disagreeing with you Cool Wink

egc said generating a RSA-4096 key takes 1-10min depending on the processor.
Generating an ed25519 key pair takes about 20-500ms with comparable key strength (RSA-4096 or RSA-3072).

And yes ed25519 is not only stronger in generating but also in authenticating, ed25519 is also immune against side channel attacks and against weak random number generators.

on the whole, ed25519 offer up to 100x better performance with comparable and better security Wink

The big thing adopting ED25519 depends on here is what defaults are absolutely required to compile a 100% functional dropbear binary with current options (like SFTP). If we can default to only using ED25519 and no other ciphers, great. But you still have to make room for it across the board for all supported devices which include dropbear, which is a key factor. This is where people who can successfully compile firmware images would be key in putting a proposal together, because they might also know where fat can be trimmed to make room.

I'm not sure if this belongs in here or in a build thread (I mentioned it in one only. see https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=1274008#1274008)

Needed to ensure that a headless system was downloading, had to look into status / bandwith:

Seems like some kind of scaling is happening?
Same for Waterfox / msedge and Duckduckgo. On mobile and PC.

No real issue, I just increased the zoom level to decipher it =)

@Zyxx https://svn.dd-wrt.com/ticket/7601

Fixed already with https://svn.dd-wrt.com/changeset/50559

Having any scripts in place now shows edit for all available script options. This wasn't like this before, it only showed command input box and whichever script was in place. Not sure when this was introduced as this is a remote device that gets updated once every month or two. TL-WR940Nv3.

The problem being that there are no user-added shutdown, firewall, or custom scripts, but the text boxes and edit button are there for them. This may not affect all devices, and I only use browsers set to clear cache on exit and use private browsing mode. I only used Edge to get a web capture of the page after clearing it's cache. Forgot to get a screenshot of page source, etc. and I'm not driving to this device to get it, that'll have to wait until I am on site again.

Cant please everyone at te same time, and not going to try.

logout is here to stay.

Re: multiple edits visible fields when there are none configured.

Any reported bugs in this area are non reproducible across test remote access machine r6800 and my own router Broadcom based, so this is like many other edge bugs reported and which remain unfixed. None of my work affects this anyway, but feel free to blame me, wide shoulders.
