ssh_exchange_identification

(2015-06-05)

Seems like a terribly late date to still be messing around with clunkers like these, but oh well

Problem

ASA 5505 factory default, can't ssh in, ssh client gets error

ssh_exchange_identification: Connection closed by remote host

Solution

Generate rsa crypto keys:

conf t
crypto key generate rsa modulus 2048
end
wr mem
