Offending key for IP in /builds/hudson/.ssh/known_hosts:36

當ssh訪問一臺server時，如果出現“Warning: the RSA host key for differs from the key for the IP address”這樣的資訊，表示在known_hosts裡已經有一臺server和你正要訪問的server的IP衝突。
另外一條類似於這樣的資訊“Offending key for IP in /builds/hudson/.ssh/known_hosts:36″，表示IP衝突位於known_hosts的第36行， 只要開啟~/.ssh/known_hosts，刪除第36行就可以將問題解決，或者直接執行一條命令搞定“sed -i -e ’36d’ ~/.ssh/known_hosts”。
如果你想徹底擺脫known_hosts，將“StrictHostKeyChecking no”新增到~/.ssh/config，這樣以後訪問新的server都不在有known_hosts的提示。
