Logan commented on SSHD-1129:
-----------------------------
I stand corrected with Jsch API support for owner and group details. Currently
Jsch API return 0 for UID/GID in line with their [documentation
|https://epaul.github.io/jsch-documentation/javadoc/com/jcraft/jsch/SftpATTRS.html]
Here is the code snippet just in case.
Is there a way to know server O/S ?
{code:java}
public void testWithJsch()
throws IOException, JSchException, com.jcraft.jsch.SftpException {
final JSch jsch = new JSch();
Session session = null;
try {
session = jsch.getSession(user, hostname, port);
Properties sessionProps = new Properties();
sessionProps.put("StrictHostKeyChecking", "no");
session.setPassword(password);
session.setConfig(sessionProps);
session.setServerAliveInterval(300000);
session.connect(60000);
ChannelSftp channelSftp = null;
try {
channelSftp = (ChannelSftp) session.openChannel("sftp");
channelSftp.connect(60000);
Vector<ChannelSftp.LsEntry> entries = channelSftp.ls("/tmp");
for (LsEntry entry : entries) {
SftpATTRS attrs = entry.getAttrs();
System.out.println("owner id: " + attrs.getUId() + " group id: " +
attrs.getGId() + " extended: " + toString(attrs.getExtended()));
}
} finally {
if (channelSftp != null) {
channelSftp.disconnect();
}
}
} finally {
if (session != null) {
session.disconnect();
}
}
}
