search for: ssh_connect_direct

if the remote hostname has multiple ip addresses, ssh_connect_direct will currently loop and try each address in sequence until one works. I'm interested in making ssh tries each address concurrently and return success on the first one that connects. in the land of host certs and ssh bastions, this can be incredibly effective. are there any objects to me worki...

I would have thought that using non-blocking connect (ie set O_NONBLOCK on the fds, initiate the connections then select on the set until one succeeds) woul...

...ndrot.org Reporter: dvw at phas.ubc.ca Using ssh with ConnectionAttempts set to zero results in the contents of uninitialised memory being sent to stdout. For example: $ ssh -o ConnectionAttempts=0 somehost ssh: connect to host somehost port \200\335q\002\374\177: Success Cause: When ssh_connect_direct() is passed connection_attempts=0, the strport[] buffer is never initialised, since the whole attempt loop is skipped.

Hi, I'm having a problem when I add "HostKeyAlgorithms +ssh-dss" to the ssh_config file the host key will always negotiate to a wrong one. In my case it will negotiate to "ecdsa-sha2-nistp256". The client was already configured with the servers rsa public key, before the change I added to the ssh_config file I could see from the debug that server and client will negotiate

Hello. I am running OpenSSH 7.9p1 on my client and server. ssh-keyscan shows the server has ssh-rsa, ssh-ed25519, and ecdsa-sha2-nistp256 host keys. My /etc/ssh/ssh_known_hosts file contains the server's ssh-ed25519 host key. When I try to SSH to the server I get this error: @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
