ssh -o HostKeyAlgorithms=+ssh-rsa firstname.lastname@example.org
Unable to negotiate with 10.129.79.186 port 22: no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1
Then when I enter:
ssh -o KexAlgorithms=+diffie-hellman-group1-sha1 email@example.com
Unable to negotiate with 10.129.79.186 port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss
Is my commands wrong or something wrong with the host. Maybe another similar issue with connecting to legacy hosts from an up-to-date Kali box? Thank you for the help.
