[How to update Lets Encrypt Root Certificate]

On 10/12/2021 at 6:17 PM, Mustyone said:

Lets Encrypt's root certificate expired on October 1, 2021, which causes the cert renewal or creation to fail with a message "No response from destination server. Please try again later."

 

To Fix follow the following instruction which worked for me on my Xpenology box running DSM 6.2.2-24922

 

1.      Download root cert from LetsEncrypt website: https://letsencrypt.org/certificates/

a.      Download Active Root Cert “Pem” file,

b.      Open with text editor, and copy cert

2.      Log into Synolog box via ssh

3.      Back up CA cert file: cp /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/ca-certificates.crt.ORIG

4.      Edit CA cert file : sudo vi /etc/ssl/certs/ca-certificates.crt

5.      “ESC” “G” to go to end of file

6.      “o” to insert new line

7.      Paste new cert into file.

8.      “ESC”, “w”, “q”, “!” to save and close.

 

This will update the root CA cert and should allow you to now install or renew Lets Encrypt certificates

 

Thank you so very much! Worked like a charm :)

[Change MAC address AFTER DSM 6 install?]

@Polanskiman I finally managed to get it to work :) I got my new Dell R510 up and running and used this opportunity to upgrade to ESXi 6.7. This enabled me to use this guide: https://advanxer.com/blog/2018/12/install-xpenology-dsm-6-2-1-on-esxi-6-7-ready-made-ova-file/ It worked very nicely and now I am able to edit SN and MAC address. So I made a couple of new Xpenologies and this time they remain on the same SN and MAC after a power cycle. And editing with the "c" during boot works as well.

Thanks for your help along and support during these somewhat challenging weeks :)

@Polanskiman Thanks for your input.
My primary ESXi server is currently crashed so I am running on my (very weak) backup server. New parts will arrive next week so I will continue work on this once everything is up and running.
I’ll get back to you at that time [emoji4]

@Polanskiman
I wouldn’t know where to start 🤪
So - the answer is no 😊

@Polanskiman I believe it's 1.02b. I haven't gotten around to updating it yet. I have the very same GNU GRUB version 2.02 beta as in your screen dump. And I agree that the commands should work. But as you can see from my screen dump ... they don't

@bearcat

Thanks for following up on this ... actually I tried pretty much all combinations; with the ":" in the address, without, with ":" after "mac1". You name it - I tried it. The darn grub just won't recognize the "mac1" command. Which in a way makes sense - if I list all grub commands with the "TAB" key, mac1 definitely isn't one of them.

Anyway - as you also mention ... it's sorted out now

If you are curious  why I am spending so much time on this issue, it's because I want to have a number of XPe's running on my ESXi. This way I can do some tests without messing up my main XPe. My primary ESXi (and the entire XPe data VMDK) crashed the other day ... that hurt😭. So moving forward caution and backups are going to be my main focus 🤓

No worries

Thank you so much for your reply. I am a noob in Linux so it took me way too long to figure things out. But when I figured out that the line with the three dots indicated when I should edit the grub.cfg things started to work (mind you - the VIM editor and me are not good friends)

So I have now successfully changed the MAC address .. and this time the XPe keeps it after a reboot

 

Thanks again

I also tried to modify in the other menu ... this does actually change SN and MAC, but it doesn't retain the changes after a reboot.

 

 

I might add that I have XPenology running on a ESXi 6.0 server.

Thanks for your swift reply @siulman and yes - it does sound obvious. But as my screenshot shows ... I can't get it to accept my entry

Any hints?

[Change MAC address AFTER DSM 6 install?]

@siulman  wrote in this old thread ... "by pressing C in grub menu, enter "mac1 your_mac" in command line, then ESC and boot." I simply cannot make this work. 

I have no problems getting into the grub menu pressing c. Then I get the command line.

If I finish the mac1 command with <enter> it will say unknown command; if I go into the e menu/screen I can move the cursor to the MAC position and modify the mac address. This will work for one boot,  but it won't keep the changed after a reboot.

 

Could you or somebody else shed some light on what I am doing wrong, please

 

Thanks
