求助：关于使用ganymed-ssh2-build210.jar执行多条命令的问题

[wenhuifen]

最近碰到一个问题，ganymed-ssh2-build210.jar中可以在一个session里执行多条命令？
代码如下：
try {
ConnectionInfo info = conn.connect(null,time_out,0);
boolean result = conn.authenticateWithPassword(username, password);
if (result!=false) {
Session sshsession = conn.openSession();
for (int i = 0; i < commands.size(); i++){
if (sshsession!=null) {
sshsession.execCommand(commands.get(i));
in = new StreamGobbler(sshsession.getStdout());
reader = new BufferedReader(new InputStreamReader(in));
String response = null;
while ((response = reader.readLine()) != null)
builder.append(response + "\n");
sshsession.waitForCondition(ChannelCondition.EXIT_STATUS | ChannelCondition.CLOSED | ChannelCondition.EOF,time_out);
if(sshsession.getExitStatus()==null){
break;
}
}
}
if (builder.toString().isEmpty()) {
for (String command : commands) {
builder.append(command + ": command not found\n");
}
}
}
resu = builder.toString();
resu = new String(resu.getBytes());
return resu;
}catch (IOException e) {
logger.fatal("error", e);
return e.getMessage();
} finally {
if (reader != null) {
try {
reader.close();
in.close();
} catch (final IOException e) {
logger.fatal("error", e);
}
}
conn.close();
}

这里执行完一条命令后 sshsession.getExitStatus()始终为null，导致不能继续执行下一条命令

我也有这样的问题，主要是用来服务器的跳转，不知道怎么弄。期待中。。。。

楼主，问一个菜鸟级的问题，登录时一直出现connection refused是怎么回事啊？我用putty可以连上的。。。

PrintWriter pw = new PrintWriter(new OutputStreamWriter(sess.getStdin())); pw.write("cd /home"); pw.flush(); pw.write("pwd"); pw.flush();

引用 3 楼 lhn760865548 的回复:

PrintWriter pw = new PrintWriter(new OutputStreamWriter(sess.getStdin())); pw.write("cd /home"); pw.flush(); pw.write("pwd"); pw.flush();

不对啊，这样怎么让它开始执行你所输入的这些命令呢？？？
