Ruijie Switch connected failed with message 'Auth fail for methods 'publickey,password' #333

Closed zhanglinqiang closed 1 year ago

zhanglinqiang commented 1 year ago

Hi, In my case, ssh target is Ruijie Switch. Using linux ssh command can connect successful. I tried 0.1.72 and 0.2.9 and both failed. After I manually set "PreferredAuthentications" to "password,publickey", failed with 'Packet corrupt', suffix xxx is my message appending. Can anyone help?

connect testing code:

try {
                log.info("PreferredAuthentications: {}", session.getConfig("PreferredAuthentications"));
                session.connect(120000);
            } catch (JSchException e) {
                log.error(e.getMessage(), e);
                log.error("try again: ");
                session.setConfig("PreferredAuthentications", "password,publickey");
                log.info("PreferredAuthentications: {}", session.getConfig("PreferredAuthentications"));
                session.connect(120000);
            }

failed message:
