Hi,
When I login to the unix box manually I can ssh without a prompt for the
password because my user has been set to autologin. How do i replicate
this through JSch?
I tried setting a blank user info implementation under the premise that
it wouldn't be required as long as my program is executing under the
user that is allowed to autologin to the remote box. Unfortunately
receiving this error message when trying to run.
com.globeop.ti.tci.decrypt.PgpException: com.jcraft.jsch.JSchException:
Auth cancel
at
com.globeop.ti.tci.decrypt.SshPgpClient.decryptTradeFile(SshPgpClient.ja
va:56)
at
com.globeop.ti.tci.decrypt.SshPgpClient.main(SshPgpClient.java:119)
Caused by: com.jcraft.jsch.JSchException: Auth cancel
at com.jcraft.jsch.Session.connect(Session.java:450)
at com.jcraft.jsch.Session.connect(Session.java:149)
Any help would be much appreciated.
Thanks,
