Ssh_dispatch_run_fatal

When I try to login old ios Switch version I am encountering below error, Do you have any idea to fix this error

ssh_dispatch_run_fatal: Connection to 192.168.50.81 port 22: error in libcrypto

Hi Mithu and Welcome to Fedora :slight_smile:
Give this a try:
sudo update-crypto-policies --set LEGACY
reboot

This will make your ssh a bit more forgiving of older protocols …
To revert:
sudo update-crypto-policies --set DEFAULT
reboot
