We have our web site on Blueshield LINUX rental share server. I made a PHP program for our customer can imput their timesheet. I also am using mySQL to store these timesheet data Then I have to send these timesheet data as dbf file or csv file or some text file to our intra Windows 2012 server in our office in safe. Because in this server we have a FOX-Pro program to calculate payroll So I want to send timesheet data file from my PHP program on LINUX serve to our intra Windows server automatically in safe when our customer finished to input
And when customer finished to input, I want to inform that to our intra Windows server and our staff like by email or text message. I tried this by FTP or Samba or Dropbox but I failed and it seems not safe.So if you have good idea to send file in safe, please let me know. File size is not big.But our intra server has customer's important data. So safety is most important. I am a just programmer. I am not good at network and server. Our CEIO made Fox-pro program to calculate payroll so we still use this to calculate payroll. maybe VPN is one solution but very expensive. I need safe but easy, cheap solution.Do you have any good idea to solve this?
