Hello Irvin
Indeed, in the lesson as well, this command does throw an error, but the process in the lesson is able to continue. As it states in the lesson:
We can download the root certificate from the vManage controller using the request command. Here’s what it looks like:
vBond1# request download scp://admin@10.1.0.1:/home/admin/ROOT-CA.pem /usr/bin/download: line 33: /proc/sys/kernel/hung_task_timeout_secs: Permission denied The authenticity of host '10.1.0.1 (10.1.0.1)' can't be established. ECDSA key fingerprint is SHA256:tDhYof1C8igzPm29fFlV5afe44qjJZAEDCNv9qQ2gPE. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '10.1.0.1' (ECDSA) to the list of known hosts. viptela 19.3.0 admin@10.1.0.1's password: ROOT-CA.pem 100% 1257 41.1KB/s 00:00 /usr/bin/download: line 33: /proc/sys/kernel/hung_task_timeout_secs: Permission denied
It throws an error but it does work. With another request command we can install the root CA certificate:
Take a look again and see if the process allows you to continue like in the lesson, even if it gives you an error…
I hope this has been helpful!
