Thank you for the above and the following list. It does not affect me really, as i used "HostKeyAlgorithms ssh-rsa" and IdentityFile for the few hosts that use RSA (even exclusively, like elder Solaris installations i have access to), but i obviously did not really understand what the RSA change meant. --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt) _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
