README of example directory
====================================================================
Last modified: Wed Oct 16 13:53:12 UTC 2002
This directory contains some examples, which demonstrate how to use JSch
- Shell.java
This program enables you to connect to sshd server and get the shell prompt.
$ CLASSPATH=.:../src javac Shell.java
$ CLASSPATH=.:../src java Shell
You will be asked username, hostname and passwd.
If everything works fine, you will get the shell prompt. Output will
be ugly because of lacks of terminal-emulation, but you can issue commands.
- X11Forwarding.java
This program will demonstrate X11 forwarding.
$ CLASSPATH=.:../src javac X11Forwarding.java
$ CLASSPATH=.:../src java X11Forwarding
You will be asked username, hostname, displayname and passwd.
If your X server does not run at 127.0.0.1, please enter correct
displayname. If everything works fine, you will get the shell prompt.
Try X applications; for example, xlogo.
- Exec.java
This program will demonstrate remote exec.
$ CLASSPATH=.:../src javac Exec.java
$ CLASSPATH=.:../src java Exec
You will be asked username, hostname, displayname, passwd and command.
If everything works fine, given command will be invoked
on the remote side and outputs will be printed out. In this sample,
X forwarding is enabled, so you can give an X client as a command.
- ViaHTTP.java
This program will demonstrate the ssh session via HTTP proxy.
$ CLASSPATH=.:../src javac ViaHTTP.java
$ CLASSPATH=.:../src java ViaHTTP
You will be asked username, hostname, proxy-server and passwd.
If everything works fine, you will get the shell prompt.
- PortForwardingR.java
This program will demonstrate the port forwarding like option -R of
ssh command; the given port on the remote host will be forwarded to
the given host and port on the local side.
$ CLASSPATH=.:../src javac PortForwardingR.java
$ CLASSPATH=.:../src java PortForwardingR
You will be asked username, hostname, port:host:hostport and passwd.
If everything works fine, you will get the shell prompt.
Try the port on remote host.
- PortForwardingL.java
This program will demonstrate the port forwarding like option -L of
ssh command; the given port on the local host will be forwarded to
the given remote host and port on the remote side.
$ CLASSPATH=.:../src javac PortForwardingL.java
$ CLASSPATH=.:../src java PortForwardingL
You will be asked username, hostname, port:host:hostport and passwd.
If everything works fine, you will get the shell prompt.
Try the port on localhost.
- StreamForwarding.java
This program will demonstrate the stream forwarding. The given Java
I/O streams will be forwared to the given remote host and port on
the remote side. It is simmilar to the -L option of ssh command,
but you don't have to assign and open a local tcp port.
$ CLASSPATH=.:../src javac StreamForwarding.java
$ CLASSPATH=.:../src java StreamForwarding
You will be asked username, hostname, host:hostport and passwd.
If everything works fine, System.in and System.out streams will be
forwared to remote port and you can send messages from command line.
- UserAuthPubKey.java
This program will demonstrate the user authentification by public key.
$ CLASSPATH=.:../src javac UserAuthPubKey.java
$ CLASSPATH=.:../src java UserAuthPubKey
You will be asked username, hostname, privatekey(id_dsa) and passphrase.
If everything works fine, you will get the shell prompt
- Compression.java
This program will demonstrate the packet compression.
$ CLASSPATH=.:../src javac Compression.java
$ CLASSPATH=.:../src java Compression
You will be asked username, hostname and passwd.
If everything works fine, you will get the shell prompt.
In this program, all data from sshd server to jsch will be
compressed.
- ScpTo.java
This program will demonstrate the file transfer from local to remote.
$ CLASSPATH=.:../src javac ScpTo.java
$ CLASSPATH=.:../src java ScpTo file1 user@remotehost:file2
You will be asked passwd.
If everything works fine, a local file 'file1' will copied to
'file2' on 'remotehost'.
- ScpFrom.java
This program will demonstrate the file transfer from remote to local
$ CLASSPATH=.:../src javac ScpFrom.java
$ CLASSPATH=.:../src java ScpFrom user@remotehost:file1 file2
You will be asked passwd.
If everything works fine, a file 'file1' on 'remotehost' will copied to
local 'file1'.
- Sftp.java
This program will demonstrate the sftp protocol support.
$ CLASSPATH=.:../src javac Sftp.java
$ CLASSPATH=.:../src java Sftp
You will be asked username, host and passwd.
If everything works fine, you will get a prompt 'sftp>'.
'help' command will show available command.
In current implementation, the destination path for 'get' and 'put'
commands must be a file, not a directory.
- KnownHosts.java
This program will demonstrate the 'known_hosts' file handling.
$ CLASSPATH=.:../src javac KnownHosts.java
$ CLASSPATH=.:../src java KnownHosts
You will be asked username, hostname, a path for 'known_hosts' and passwd.
If everything works fine, you will get the shell prompt.
In current implementation, jsch only reads 'known_hosts' for checking
and does not modify it.
- UserAuthKI.java
This program will demonstrate the keyboard-interactive authentication.
$ CLASSPATH=.:../src javac UserAuthKI.java
$ CLASSPATH=.:../src java UserAuthKI
If the remote sshd supports keyboard-interactive authentication,
you will be prompted.
- KeyGen.java
This progam will demonstrate the DSA keypair generation.
$ CLASSPATH=.:../src javac KeyGen.java
$ CLASSPATH=.:../src java KeyGen rsa output_keyfile comment
or
$ CLASSPATH=.:../src java KeyGen dsa output_keyfile comment
You will be asked a passphrase for output_keyfile.
If everything works fine, you will get the DSA or RSA keypair,
output_keyfile and output_keyfile+".pub".
The private key and public key are in the OpenSSH format.
- ChangePassphrase.java
This program will demonstrate to change the passphrase for a
private key file instead of creating a new private key.
$ CLASSPATH=.:../src javac ChangePassphrase.java
$ CLASSPATH=.:../src java ChangePassphrase private-key
A passphrase will be prompted if the given private-key has been
encrypted. After successfully loading the content of the
private-key, the new passphrase will be prompted and the given
private-key will be re-encrypted with that new passphrase.
