SSH - Programs are all "Killed"


I’m following the article located at to setup a custom php.ini file.

When it gets to setting up crontab, the text editor comes up, but not more than a few seconds later, it quits and “Killed” is displayed. What’s going on?

VI also quits too. Am I unable to run editors from SSH? I’m using Putty.

What do I need to do?
