I was having problems with my sendmail server, but when I fixed the problem, I startedd getting strange emails in my root users mailbox. The messages read like this:
From operator@blah(Cron Daemon)
Subject Cron <operator@blah> /usr/libexec/save-entropy
Could not load host key: /usr/local/etc/ssh_host_key
Could not load host key: /usr/local/etc/ssh_host_rsa_key
Could not load host key: /usr/local/etc/ssh_host_dsa_key
Disabling protocol version 1. Could not load host key
Disabling protocol version 2. Could not load host key
sshd: no hostkeys available -- exiting.
So I'm getting about 100 of these a day. So what I did was chmod 777 /usr/local/etc/ssh_host_key and the rest (I know that this isn't a safe practice). The emails stop coming, but now I get "failed to bind to address" errors from ssh about every 5 - 15 minutes. So I chmod 700 the keys again, and the emails start coming again, but no more errors from ssh. I don't think that this is much of a big deal, but I would like to know why this is happening all of a sudden.
By the way, the ssh server was working correctly the whole time it seemed.
Thanks for any help.
