Dear PHP users,
I am trying to write a php script that allows me to schedule jobs using the
at deamon (unix) for execution
in the arbitrary future. I have everything working except that the default
login shell for apache (nologin)
means that the at deamon fails to execute the command.
If I run the at command as another (not apache) user or change the apache
login script to bash then
everything works fine.
I understand the nologin shell is a security feature for the apache account
so i am reluctant to change it.
AT is supposed to use the shell defined by the SHELL environment variable at
the time of job submission but this does not appear to work in this case.
I have tried wrapping the command in a setuid script to use another user id
to side step this but I think
scripts are prevented from using setuid.
I could sidestep this by making a setuid executable but this seems like a
desperate measure and that there should be a more sensible way of achieving
this safely.
So does anyone have any suggestions? since "at" is a common word looking for
solutions on the web
is rather difficult...
Cheers,
SA
