What is the output of "date -u +%V$(uname)|sha384sum|sed 's/\W//g'"?


The question appears in the registration form of the ArchLinux forum. I get
Code:
[root@revenge Downloads]# date -u +%V$(uname)|sha384sum|sed 's/\W//g'
8200e4c9600c8a6e8a69895104d20abfe4d0eaff5593af3e7afc0add9e7aa81fa17480807eb1123de6c6223c5167eb4b
[root@revenge Downloads]#
but the answer is rejected!

Are you running it with on an Arch box? Maybe the output of uname is different on Arch?

That, or since it's dependent on the current "week number", there is some major clock drift on their server? (I get the same result as you, by the way).

What do you mean, Habitual. I am trying to register again and now the question is:
What is the output of "date -u +%V$(uname)|sha224sum|sed 's/\W//g'"?
This seems kind of a joke.

Oh yes, this is Arch Linux. In regard to the registration I found the following post:
https://bbs.archlinux.org/viewtopic.php?id=170564
The forum URL is https://bbs.archlinux.org/register.php?action=register

This seems kind of a joke.
On my non-Arch system / (my Mac is missing a 'couple' of utilities, so I use my "bat-cave")
today, I issued
Code:
date -u +%V$(uname)|sha224sum|sed 's/\W//g'
and got back
PHP Code:
f6abd11a0ce3b33dc62c23224df92c7e3d88b7df05d96c440e7eec28 
Yesterday, I issued these commands
Code:
root@habitual.guru ~ # date -u +%V$(uname)|sha384sum|sed 's/\W//g'
8200e4c9600c8a6e8a69895104d20abfe4d0eaff5593af3e7afc0add9e7aa81fa17480807eb1123de6c6223c5167eb4b
root@habitual.guru ~ # date -u +%V$(uname)|sha512sum|sed 's/\W//g'
4a126d473efd5cb336532097051882574eb13526fb12b2f90561f8eac96ee672d8d518a8ad75f318649b39717b4c8e4b65478eab293cfad72ff6088eeb54e72c
I'm not sure who you think is joking you but this appears to be a rotating captcha, likely meant to defeat Forum Spam/Bots

All 3 variants used in 2 days by me
Code:
date -u +%V$(uname)|sha384sum|sed 's/\W//g'
Code:
date -u +%V$(uname)|sha512sum|sed 's/\W//g'
Code:
date -u +%V$(uname)|sha224sum|sed 's/\W//g'
I will note that Firefox 59.0.2 doesn't even present that Question on the same page.
in my newly installed FF.

Details at http://termbin.com/19ju

Other than Forum Spam Defense, not sure why this happens.

I still don't understand. What made you try with sha512sum?

I did not "try" anything.
I did as instructed at https://bbs.archlinux.org/register.php?agree=Agree
and entered the variant it showed me.

Good day.
