When I first connect to an SSH server with ECDSA public keys, this key is added to known_hosts, and consequently it must be verified in all subsequent connections. KDE's KIO_SFTP fails to verify such keys, while the ssh command line program works perfectly. The workaround is to add a different ssh host key to the known_hosts file. This could be achieved by making the first connection to the SSH server specifying a different host key algorithm: $> ssh -o HostKeyAlgorithms=ssh-rsa root@host After doing this, everything works as expected. Reproducible: Always Steps to Reproduce: 1. Connect for the first time to a SSH server with openssh version >= 5.8. 2. Copy a file with the sftp kio slave: $> kioclient copy sftp://HOST:test.txt . Actual Results: Host key fails verification Expected Results: The file should be copied from the remote server Reply at: https://bugs.launchpad.net/ubuntu/+source/libssh/+bug/1176970/comments/0 ------------------------------------------------------------------------ On 2011-04-08T11:10:52+00:00 3-asn wrote: Thanks for taking the time reporting a bug.

Balancing life and free software is a difficult task, as a fellow open source developer I can definitely sympathize. >From a pragmatic point of view, should we consider re-opening the KDE issue if upstream isn't able to make a release? Maybe there is some stop gap we could provide that could help users understand why they can't connect and how to fix it? Also, I almost don't want to say it but is there other maybe another library KDE should consider using? It'd be nice to getting it moving toward a solution or at least provide some insight into it what's going would go a long way I think. Thanks!

Should this bug really be resolved as upstream? KDE could work around this bug in the meantime, and I wonder if it indeed should. At the very least, the error message needs to be rewritten so that it is actually accurate and useful. The workaround could be referenced in some way.

The PKI has been completely rewritten to support ECDSA. We currently working on timeout fixes and some changes in the server part of libssh and hope to get libssh 0.6 out of the door pretty soon. The only thing distributions could do is to package the current libssh master tree. It should be pretty stable, we've written a lot of unit tests for the stuff.

I've just found this bug, while googling for that problem. As you said, I've installed current libssh's master tree snapshot and get following error in dolphin: « Error. Out of memory.
