[Anthill] SCP

[Misura, Gabe]

Tim/All,

Thanks for the info.
I tried that and got this error:

preprod:
      [scp] Identity: java.lang.ArrayIndexOutOfBoundsException: 8

BUILD FAILED
D:\WSAD\Anthill\work\fakeinfoconlogin\WebContent\WEB-INF\build.xml:71:
com.jcraft.jsch.JSchException: java.lang.ArrayIndexOutOfBoundsException: 8

Probably because I didn't understand the step "create/append
{home}/.ssh/id_ra.pub into authorized_keys2". 
On my system I don't have "id_ra.pub", something close though:
bash-2.03$ ls ~/.ssh2/
id_rsa_2048_a      id_rsa_2048_a.pub  random_seed

And there is no authorized_keys2 file on the system:
bash-2.03$ find / -name authorized_keys2 2>/dev/null
bash-2.03$

However, I grabbed the is_rsa_2048_a and pointed ant to that:
		<scp todir="user at 1xx.1xx.8x.7:/dir/dir/dir/dir"
			 trust="Yes"
			 verbose="Yes"
			 passphrase=""
	
keyFile="D:/WSAD/Anthill/lib/ant-1.6.2/keys/id_rsa_2048_a" >
			 <fileset file="${warpath}/${warfile}.war"/>
		</scp>
That gave me the error above. I also tried the .pub file, and I got
preprod:
      [scp] Connecting to 129.124.87.7:22

BUILD FAILED
D:\WSAD\Anthill\work\fakeinfoconlogin\WebContent\WEB-INF\build.xml:71:
com.jcraft.jsch.JSchException: Auth cancel

Any other ideas? Thanks

I use SCP tasks, but instead of embedding the password, I'm using keys. 

This task and info below might be helpful to you, but if not, no guarantee
implied. <grin>

 <scp   
   file="${project.dist.dir}/${project.id}.war"
   toDir="userid at servername:${deploydir}"
   passphrase="" trust="true" 
   keyFile="C:/ssh/id_rsa"/>

Quick notes:

    * Login to servername
    * generate pub/private key pair using "ssh-keygen -t rsa"
          o PuTTY? folks point out a problem with DSA keys and highly
recommend RSA keys
          o do not add a passphrase, just hit enter
    * create/append {home}/.ssh/id_rsa.pub into authorized_keys2
    * copy id_rsa (the private key) to C:/ssh/ on the client computer
    * Add JSCH library to ANT_HOME/lib from http://www.jcraft.com/jsch/
    * run ant SCP/SSHEXEC tasks, using the priv key file

Putty notes:
    * The private key can also be 'converted' using puttygen into readble
putty key
    * Add the converted key into putty (Connection-SSH-Auth)
    * change the preferred SSH proto for the session to be "2"
    * move the Blowfish cipher to the top of the list
    * Login will prompt for userid, but no password
    * Create a shortcut to "C:\WINDOWS\putty.exe -l -load and no
userid/password req'd! Cool.
