deleted the /root/.ssh folder - what should I do for for recovering the keys
Hello, I have a machine on which I deleted the /root/.ssh folder; now , I generated in the past a key file , with ssh-keygen -t rsa I pasted the contents of the public key file into some servers (authorized_keys2), so I can ssh to them without being prompted for a password. Now, I cannot ssh to these mecahines. Is there anyway I can recover the old keys I had ? Running ssh-keygen -t rsa does not solve the problem unless I **again** paste the nre gernerated key into the new machines.

Afaik, that's not possible, unless you have a backup of your .ssk folder. Regards, - - iarly selbir | ski0s :wq!

When you delete something it's not zeroed out, so unless you write over that part of the disk again the data should be recoverable. Failing that, if you have physical access to the box then it shouldn't be too hard to log in locally and copy over the new keys. If someone else has root access on the boxes (even via su -) then you could do it that way too. -c -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

You must also make sure that the authorized_keys or authorized_keys2 file(s) on the destination machine have 644 (rw-r--r--) or 600 (rw---) permissions or the destination will continue to ask for passwords. sshd requires that group and other write attributes be disabled on those files. By default, sshd wants ~/.ssh/authorized_keys. You can change that in the /etc/ssh/ssd_config file on the destination system, then restart sshd on the destination. -- - Rick Stevens, Systems Engineer ri...@nerd.com - - AIM/Skype: therps2ICQ: 22643734Yahoo: origrps2 - -- -Beware of programmers who carry screwdrivers- -- -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
