Yo All! I understand why we do not have sftp in openssh, but it would be nice if we could make it so that when an SSH.COM scp2 client makes a connection to an OpenSSH V2 daemon that it does not hang.... Any ideas or do I need to dig a bit on this? Here is what the sshd says when I conenct to it from scp2: debug: session_open: session 0: link with channel 0 debug: confirm session debug:

I do not often use X11 - but when I do I prefer to enable X11forwarding, and when finished - turn it off. This is preferable, imho, to having "clear" X11 processing when local - and otherwise impossible when working remote. Working with openssh-7.5p2 I cannot figure out what (extra) I need to do with sshd_config to get it working. I know that there is a security-fix starting with

Hello, In response to the timing analysis attacks presented by Dawn Song et. al. in her paper http://paris.cs.berkeley.edu/~dawnsong/ssh-timing.html we at Silicon Defense developed a patch for openssh to avoid such measures. Timing Analysis Evasion changes were developed by C. Jason Coit and Roel Jonkman of Silicon Defense. These changes cause SSH to send packets unless request not to,
