rahul... you can easily set up an nfs share on one of the systems, and have the other 2 boxes connect to the share wit w/r privs... this would allow a box to write to the share, with the other boxes being able read the files... if all the boxes are linux/fedora/rhel, and they're all connected to the system... it's easy to set up. peace.. -----Original Message----- From: Rahul [mailto:rahul986@xxxxxxxxx] Sent: Thursday, March 06, 2008 7:40 PM To: php-general@xxxxxxxxxxxxx Subject: Re: Re: Transferring files between computers using php Thank you all so much for replying... I guess I was very vague in describing the situation. I will write in detail: I have three computers A, B and C. To login to B and C I should use A because it has a SSH key. I don't have any other way of accessing these two computers. Now, if I need to transfer a file between B and C, I am unable to find a way that would work... because I don't know how to authenticate without SSH keys... I was gathering some data in B and C using PHP. Now, I need these two computers to coordinate a little and didn't want to use a server in between and so I was thinking of establishing a direct connection between them..
