Dell T320: ERROR: Key is too long
Hello,
I'd like to add my 8192 ssh key to iDRAC, but it seems to be too long:
sudo /opt/dell/srvadmin/bin/idracadm7 -r -u root -p sshpkauth -i 2 -k 1 -f ~/.ssh/id_rsa.pub
[sudo] password for user:
Security Alert: Certificate is invalid - self signed certificate
Continuing execution. Use -S option for racadm to stop execution on certificate-related errors.
ERROR: Key is too long. After looking for this error, I found this article that says it's supposed to be solved with firmware 2.40.40.40. I'm on 2.63.60.62 but the issue remains.
As I don't plan to regenerate an other SSH key specifically for the iDRAC, is there another workaround ? Does Dell plan to fix this issue ?
Thank you.

Aqwserf,
The 8192 ssh key is indeed too long, as the max length would be 4096.
The article you referred to was addressing the issue that 4096 keys were also being flagged as too long with SSH 6.6, hence the workaround was to create the 4096 with an older tool. The 2.40.40.40 update resolved the 4096 being flagged as too long, not to increase the key length itself.
Hope this helps.

Nobody ?
As I previously said, Dell was supposed this issue and it's still not the case...
