I don't think I mentioned on this list yesterday's test results:
salmo and caddis can ping each other;
salmo can ssh to caddis;
caddis still cannot ssh to salmo.
Just now I looked at the known_hosts file on both hosts. salmo has one line
for caddis. But, caddis has 3 lines for salmo: ED25519, RSA, and ECDSA. I
want to use only the first, but the others are added back in the file each
time I try to ssh to salmo.
In /etc/ssh/ on both hosts are multiple key pairs:
$ ls /etc/ssh
moduli ssh_host_dsa_key.pub ssh_host_ed25519_key ssh_host_rsa_key.pub
ssh_config ssh_host_ecdsa_key ssh_host_ed25519_key.pub sshd_config
ssh_host_dsa_key ssh_host_ecdsa_key.pub ssh_host_rsa_key
Can I delete the dsa, ecdsa, and rsa pairs?
