SSH HELPDESK

GOAL: ssh to the sandbox pi
the trick is that it is VIA the xpub.nl server.

I have a .ssh/config file that is like bookmarks for ssh....
Inside I have:

nano ~/.ssh/config

Host sandbox
    User mmurtaugh
    Hostname 10.0.0.11
    ProxyJump mmurtaugh@xpub.nl:2501
    Identityfile /home/murtaugh/.ssh/id_rsa
    Serveraliveinterval 30 

YOURS:
Host sandbox
    User mmurtaugh
    Hostname 10.0.0.11
    ProxyJump mmurtaugh@xpub.nl:2501
    Identityfile /home/murtaugh/.ssh/id_rsa
    Serveraliveinterval 30 

Host sandbox
    User markvandenheuvel
    Hostname 10.0.0.11
    ProxyJump markvandenheuvel@xpub.nl:2501
    Identityfile /users/markvandenheuvel/.ssh/id_rsa
    Serveraliveinterval 30 

Host sandbox
    User implicant_04
    Hostname 10.0.0.11
    ProxyJump implicant_04@xpub.nl:2501
    Identityfile /users/lena/.ssh/id_rsa
    Serveraliveinterval 30 


Host hub.sandbox
User ioanatomici
Hostname 10.0.0.11
ProxyJump ioanatomici@xpub.nl:2501
Identityfile /home/ioanatomici/.ssh/id_rsa
Serveraliveinterval 30

Host itch
User xpub
Hostname XITCHXARCHIVEX2
Port 22
Identityfile /home/ioanatomici/.ssh/id_rsa
Serveraliveinterval 30

ioanatomici@DESKTOP-CJNAHDQ:~/.ssh$ ssh hub.sandbox
Enter passphrase for key '/home/ioanatomici/.ssh/id_rsa':
ioanatomici@10.0.0.11: Permission denied (publickey).

rm .ssh/id_rsa
rm .ssh/id_rsa.pub
ssh-keygen
(hit enter for all defaults)
cat ~/.ssh/id_rsa.pub

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDFrMM+4s4h60uaznTNsg1FELcLvt2YS6P0O1FM7xJfagX262GG3pgMhgo5Z8j7RMRwSCUZZKcK5pyGl0qCpgBZWcji9E2Ro4ry40ufm1F/JPxgRgKhkjg0K7aBtcPu3GQwQrRsR6APfVgKX5wWST2394UBr8nkgh+rrluV10JoO9vKqC9WCo7fRrzhkcjuG9kQ4PLuVsStaJVJhoOC0tnYWOY0H7bVM2yd8lsKpW9jq+ebboCllTqeLRN/ERQqZGXgZvv3Xx0osH8xe5Y7vnfM5w/VOZfmCPeUSF9P9Hsqhu93jJ/5e2E9BaB+3yY+wBxpshrAzDsKBaZc9gxgQkmF ioanatomici@DESKTOP-CJNAHDQ

ioanatomici@DESKTOP-CJNAHDQ:~/.ssh$ ssh hub.sandbox
ioanatomici@10.0.0.11: Permission denied (publickey).

    Identityfile /Users/--------/.ssh/id_rsa

So in fact you are ssh'ing THROUGH the xpub.nl, and this needs to work for you first:
    
ssh mmurtaugh@xpub.nl -p 2501

ssh claranoseda@xpub.nl -p 2501
ssh markvandenheuvel@xpub.nl -p 2501
ssh markvandenheuvel@xpub.nl -p 2501 -i ~/.ssh/id_rsa.pub

ssh ioanatomici@xpub.nl -p 2501

In order to connect, this server is configured to require a matching sshkey (not passwords).
CHECK YOUR LOCAL (laptop) ssh key

cat ~/.ssh/id_rsa.pub

cd
