问题 I developed a tool to send one-line commands to different linux machines in one shot using JSch (A java library used to communicating with other machines over ssh) So our client needs to change the password on ALL machines.

The command executes but this is ALWAYS the output: [root@QNA-XR1 ~]# echo -e "123\n123" | passwd Changing password for root New password: Retype password: passwd:

问题 I am facing a problem with UnknownHostKey: servername , when trying to verify the host key using: jsch.setKnownHosts("target/hostname_keys"); Is it possible to use hostkey file in SSH2 format that looks like this ---- BEGIN SSH2 PUBLIC KEY ---- AAAAB3NzaC1kc3MAAACBAKKQ7hwq7 ..... w5Uw== ---- END SSH2 PUBLIC KEY ---- with JSch? Is there some good libraries that can work with SSH2 keys? 回答1: JSch does not support public keys in this format. But it's easy to convert that to known_hosts format.

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . Is it possible to do a reverse ssh connection using JSCH? If it is not, is there any other pure Java library that I can use to do a reverse tunnel SSH connection? The command I want to mimic is similar than: ssh -fN -R 7000:localhost:22 username@yourMachine-ipaddress 回答1: There is an example gist that shows how
