SSH Port Forward multiple hops

Let's use VNC server two hops away.

ssh -4 -v -A -t -L 15902:localhost:15902 user1@host1 \
ssh -4 -v -A -L    15902:localhost:5900  user2@host2

vncviewer localhost:15902

Enable VNC Server on Mac OS X remotely

Thanks Apple, they use shell.

ssh to Mac OS X

sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -activate -configure -configure -clientopts -setvnclegacy -vnclegacy yes -setvncpw -vncpw YOUR_PASSWORD  -access -on -users admin -privs -all -restart -agent -menu

<junitreport todir="build/reports">

    <fileset dir="build/reports">

    </fileset>

    <report format="frames" todir="build/reports/html"/>

</junitreport>

Auto build project with ant in Eclipse

Who needs Eclipse if there is a shell?

In Eclipse, go to Project's properties and add a new builder of type ant.

On tab Main provide:

• Build file
• Base Directory
• Desired arguments that will be passed to ant ( -Dproperty=value style)

On tab Targets provide ant tasks for targets Auto Build, After a Clean.

Now you can just change sources and save the source file, 

Eclipse will execute "Auto Build" target right away.
