If I typo my username when ssh-ing, is there a way to go back and change it?

Question

When ssh-ing (using putty, if that's relevant), I sometimes mis-type my username, and hit enter before I realise my mistake. Once prompted for a password, is there a a way to go back and re-enter my username rather than having to close the console and open a new one?

Answer 1

You can right click on the title bar of putty and select "Duplicate Session". This opens up a new window with the same settings, letting you re-enter a username and password. This works assuming that you did not specify a user name in the putty host name configuration (using just the hostname instead of user@hostname). This might not be exactly what your looking for but it's better than re-opening and setting up putty from scratch.

Answer 2

My current keyboard-only method for this, using Putty Connection Manager:

Ctrl+U:         Duplicate session
Ctrl+Shift+Tab: Back to tab with incorrect username
Ctrl+D:         Close tab with incorrect username
Ctrl+Tab:       Back to new tab, re-enter username
