problem with sshd!

[haneo]

I must resolve a problem in a remote PC "not mine" it's redhat 7.1 when i do the command:

[root@proxy tech]# /etc/rc.d/init.d/sshd start

i got this :
Generating SSH1 RSA host key: [FAILED]

and tail /var/log/message give:
nov 10 08:50:13 proxy sshd: RSA1 key generation failed

when i do:
[root@proxy tech]# ssh-keygen
Generating public/private rsa1 key pair.
Enter file in which to save the key (/root/.ssh/identity):
/root/.ssh/identity already exists.
Overwrite (y/n)? y

but this do not resolv the problem!!!
any help is welcom.

Check /etc/init.d/sshd. There will be something like 'RSA1_KEY=/etc/ssh/ssh_host_key'. This directory/file will probably be nonexistant or write protected (chmod or chattr).

If you are trying to connect to a remote system, you dodnot need to run the ssh daemon. The remote system must of course. If the key generated is incorrect, then remove everything in the /root/.ssh/ directory. Run ssh-keygen again to recreate the files.
Connecting to a remote location requires that their key resides on your system or the ssh configuration allows entry with a password. That option is controlled by the /etc/ssh/ssh-config file on the remote system. Also, if the remote system is running the ssh2 encryption, you will need to generate a key for the ssh1 encryption, which you appear to be running, to allow access without a password. I have not run the ssh-keygen program for a while, but I believe the command line option is ssh-keygen -t DSA for ssh2.
