Hi all, Here is one web portal product which is already developed using java tools. I don't know java, php or perl. But I can learn php quickly compared to java. My question is: Is it possible to develop such web portal using php & html? Let me explain how the java portal/product works: The user logs in to the portal with his user name and password thru web browser by using a public ip or for example say xyz-portal.com The user name and password are the user names of the Linux OS. So username authentication is required. In the next page, the user accesses the preinstalled applications ( these are C or Fortran apps) and submits the job. While submitting the job, he is allowed to give the command line options and input file. The input files are present in his home directory. These files should be listed in combo box. It doesn't mean that, all installed apps in linux must be listed in the portal. There should be a mechanism to add a particular application to the portal ( part of administrator's work). And all apps which are to be displayed in portal are in a different dir, say /usr/local/bin. This portal is totally based on the server. i.e. The user accesses the portal and submits his application job from client system to run the job in the server. The client system uses only web browser. So other software can not be used to do this. Regarding php, I know that linux commands can be bypassed thru php. So can any one tell me whether this can be done using php with the above mentioned conditions/facilities? Thanks & Regards, Sangamesh
