OK. I am able to setup remote key authentication between svrA and svrB. From svrA I can login to svrB with something like
[www@svrA www]$ ssh www@svrB
and I can also execute a shell script like
[www@svrA www]$ ssh www@svrB /tmp/test.sh
On svrA I have a PHP script like so:
<?
system('ssh www@svrB /tmp/test.sh someDIR');
?>
/tmp/test.sh on svrB is only a one liner like so:
mkdir /tmp/$1
I ran the script from the browser but the /tmp/someDIR is not created :(
Could it be that user nobody on svrA is *not* allowed to connect to svrB because the public key belongs to user www ? How do I rectify this ?
In the actual situation, I need to execute a shell script in svrB (from browser served by Apache on svrA) that only root can run. Please advise. I am getting very worried.
