[opensuse] Repair Broken SSH
I have a system with a broken installation of openssh, suddenly one day I can not use the scp command at all. I removed all config files relating to ssh and removed/reinstalled the openssh package, now besides the scp command being broken I can not even start the SSH service, it complains about the RSA keys are not generated. I don't care about the configuration or preserving anything. How can I restore SSH configuration to be exactly like it would be after a new installation of openSUSE? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I suppose that you delete (or rename) /etc/ssh/*, and perhaps users ~/.ssh/* - -- Cheers, Carlos E. R.

ssh-keygen as root. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

ssh-keygen as root.
That still does not generate the SSH fingerprint, like it does with a fresh configuration. Also, I still have the original issue which is when I try to SCP files to other machines it fails with the error: command-line: line 0: bad configuration option: passwordprompt -- Med Vennlig Hilsen, A.

If we're talking about openSUSE openssh package, then sshd start script should automatically create the host keys upon start, if there are no host key definitions in /etc/ssh/sshd_config and the default files do not already exist. Just have a look at /etc/init.d/sshd to see what is supposed to happen during sshd start.

You either have an alias or script named scp where that invalid option 'passwordprompt' is set (unless you actually defined that option yourself in the scp command, which I doubt). -- Martti Laaksonen -- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I never changed the scp script, so how do i reset everything in ssh and scp to be like it was with a new installation? -- Med Vennlig Hilsen, A. Helge Joakimsen -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Please consider trimming your quots. rpm -qf `which scp` will tell you which package contains scp rpm -qfl `which scp` will provide you with the included files those named ...config... or ...conf... and/or existing below /etc/ usually relate to configuration some of which will exise below ~/.ssh/ zypper in -f openssh will reinstall the package but does not overwrite changed configuration files -- Patrick Shanahan Plainfield, Indiana, USA HOG # US1244711 http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535 @ http://counter.li.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Like I said I want to reset SSH config to *EXACTLY* like it is immediately after a new installation. I don't want to preserve anything! Anyways I've gotten SCP working and just installed telnet-server which works as well as sshd, so I consider this "resolved enough." -- Med Vennlig Hilsen, A.

Just to clarify, scp, as installed from openssh package, is an executable binary _not_ a script. If you're still having problems with sshd/scp after re-installing openssh like Patrick instructed in another response, then you could enter command type -a scp in a terminal to see how your shell would interpret scp if used as a command name (assuming that bash is your default shell). It should print something like this (in openSUSE 11.3): testuser@darkside:~> type -a scp scp is /usr/bin/scp scp is /usr/bin/X11/scp If, on the other hand, you have an scp alias or a script called scp lurking somewhere in your shell's PATH, you might see something like this instead: testuser@darkside:~> type -a scp scp is aliased to `scp -o passwordprompt' scp is /home/testuser/bin/scp scp is /usr/bin/scp scp is /usr/bin/X11/scp -- Martti -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
