I want to login in remote server, git server, with two accounts (mars and gitolite) without password. e.g. (steps) 1. ssh-keygen? # no password 2. scp .ssh/id_rsa.pub gitolite at gitserver:/tmp/ 3. ssh gitolite at gitserve 4. cat /tmp/id_rsa.pub >> .ssh/authorized_keys 5. exit Then, do : ssh gitolite at gitserver ls But error message occurs:? Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password). However, when cat the id_rsa.pub to the end of mars account's .ssh/authorized_keys, that's OK. Why? Please help me ! Thank you so much.
