I log into numerous machines as part of my job (+- 20 per day). I only spend a few days/weeks with each machine. Many run ftp only.
For seamless access Tramp is amazing, but it is the managing of these server's access by hand that has become tedious.
I manage a .netrc and a .ssh/config by hand, along with any keys. Often a password/key will change during my time with the machine, and I will have to re-edit the files.
Is there an effective solution for managing (machines/passwords/keys) from within emacs?
