web-based telnet-quota system?

hi, we have a netapp filer that stores all our user home directory. there's a text-based config file that controls the uesr quotas. currently, to changed user quota, we need to edit the quota file, telnet to netapp, execute a "quota off" and then "quota on" command to effect the change. i'm thinking of using PHP to write a web-based program to automate this process. pls kindly advise how should i go about doing it. thanks.
