HP iLO ssh access

Even the most recent version of iLO is trying to use cypher algorithms that have been deprecated in OpenSSH:

ssh Administrator@10.1.0.235
Unable to negotiate ... no matching key exchange method found.
Their offer: diffie-hellman-group14-sha1,diffie-hellman-group1-sha1
ssh Administrator@10.1.0.235 -oKexAlgorithms=+diffie-hellman-group1-sha1 
Unable to negotiate ... no matching host key type found.
Their offer: ssh-rsa,ssh-dss
Unable to negotiate ... no matching cipher found. Their offer: aes256-cbc,aes128-cbc,3des-cbc

… and the winner is:

ssh Administrator@10.1.0.235 -oKexAlgorithms=+diffie-hellman-group1-sha1 -oHostkeyAlgorithms=+ssh-rsa -oCiphers=+aes256-cbc
