com.jcraft.jsch.JSchException: Auth cancel
- by Dan Fabulich
I'm trying to write an Ant script to retrieve an URL via port tunnelling.
It works great when I use a password (the names xxxx'd out for privacy):
<project default="main">
<target name="main">
<sshsession host="xxxx"
username="xxxx"
password="xxxx">
<LocalTunnel lport="1080" rhost="xxxx" rport="80"/>
<sequential>
<get src="http://localhost:1080/xxxx" dest="/tmp/xxxx"/>
</sequential>
</sshsession>
</target>
</project>
But it doesn't work when I use a keyfile, like this:
<sshsession host="xxxx"
username="xxxx"
keyfile="/Users/xxxx/.ssh/id_dsa"
passphrase="xxxx">
<LocalTunnel lport="1080" rhost="xxxx" rport="80"/>
<sequential>
<get src="http://localhost:1080/xxxx" dest="/tmp/xxxx"/>
</sequential>
</sshsession>
I get this exception:
/tmp/build.xml:8: com.jcraft.jsch.JSchException: Auth cancel
at com.jcraft.jsch.Session.connect(Session.java:451)
at com.jcraft.jsch.Session.connect(Session.java:150)
at org.apache.tools.ant.taskdefs.optional.ssh.SSHBase.openSession(SSHBase.java:223)
I'm sure I'm using the correct keyfile (I've tried using the wrong name, which gives a legitimate FileNotFoundException).
I can successfully ssh from the command line without being prompted for a password.
I'm sure I'm using the correct passphrase for the keyfile.
What's the cause of this error and what can I do about it?
