ssh not working

matthew mills — Wed, 02 Jul 2003 15:49:06 GMT

I loaded openssh correctly but when I execute /usr/local/sbin/sshd as root I get the following error.
Could not load host key: /usr/local/etc/openssh/ssh_host_key
Could not load host key: /usr/local/etc/openssh/ssh_host_rsa_key
Could not load host key: /usr/local/etc/openssh/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 tryed to create the rsa and dsa by using:
ssh-keygen -t rsa -f /usr/local/etc/openssh/ssh_host_rsa_key
ssh-keygen -t dsa -f /usr/local/etc/openssh/ssh_host_dsa_key

no luck! same error when I run sshd.

thanks for the help!

Check here:

Looks strange that ssh can't load these keys,they are created upon install time.Probably not so good install?

You need to uncomment the type of key that you are using in your sshd_config file, if it doesn't know where to find the key, it can't load them

I'm attaching a word document that should help you.

This is probably a permissions issue. Pay close attention to what Chris says about permissions.

Ok,I guess that public keys are not created.
ssh use 2 keys - private and public.Go to
/usr/local/etc/openssh (or where keys are stored) and check for *.pub files.If they aren't sshd wouldn't boot.I guess they should
be created with ssh-keygen.By the way - does
ssh-keygen say something after you run it?Probably need more options (like -N "" ) or else?

You need to create the ssh_host_key as well.

Hi, friend!

I got the same message.
You have to regenerate your keys:
ssh-keygen -t rsa -f /usr/local/etc/openssh/ssh_host_rsa_key
ssh-keygen -t dsa -f /usr/local/etc/openssh/ssh_host_dsa_key

But do NOT enter a passfrase, only press enter.

After that, if you want to run sshd with user root, you have to modify the configuration file(sshd_config):
uncomment this line and change to "no".
UsePrivilegeSeparation no

Good Luck!!
