Hello, While playing around with various openssh features and options, I tried to use `scp -3' which copies files between two remote systems. It works fine if password is not required for either SRC or DEST systems, and if password is required only for one remote system (either SRC or DEST). The problem happens only if both SRC and DEST systems require a password. Here is a session: ---------------------------- scp -3 andyt2 at majesty:/etc/group andyt2 at mate:/tmp/group andyt2 at majesty's password: andyt2 at mate's password: XXXXXX --------------------------- As you can see, after the command is started, both remote systems prompt for a password on the same line. So I enter a password for user andyt2 and press ENTER. What happens next is probably a bug. Line advances, and nothing at all happens. So I am assuming that now the second system is waiting for a password. I enter it, and it appears in the terminal in cleartext (substituted here with XXXXXX). The command then proceeds and finishes successfully. A workaround I found is to simply press ENTER instead of typing a second password. Then, you get an error saying the password is incorrect, and a new, normal password prompt appears. Enter the password, and this time, it is not visible. This is what it looks like: ---------------------------- andyt at king: andyt> scp -3 andyt2 at majesty:/etc/group andyt2 at mate:/tmp/group andyt2 at majesty's password: andyt2 at mate's password: Permission denied, please try again. andyt2 at mate's password: ---------------------------- I imagine a similar problem may exist if a user is prompted for a passphrase. System info: All three systems run Slackware ver. 14.0, openssh-6.4. Please let me know if further clarification or test runs are needed.
