Question Compare folder contents over network
I use diff -r dir1 dir2 to get comparison of two folders that are on same machine.
Now I need the same thing but one of the folders is on a different machine.
Currently I ftp the folder to a temp folder compare using above command and delete the temp folder.
Is there any other better options?
Any command or utility which I can use over network to directly compare?

Thanks in advance

Do you need see the different content or just want to know which files are different between two servers?

if for second purpose, and you can ssh to that remote server, you can follow below steps:

Code:
1. get local dir1 md5sum

cd /dir1
find . -type f -exec md5sum {} ; |sort -k2 > dir1_md5

Sample export :

c6d19fc12bbba3ba5844e9d228c10daa *./INPUT_FILE.txt

2. get remote servers dir2 md5sum

ssh username@servername "cd /dir2; find . -type f -exec md5sum {} ; "|sort -k2 > dir2_md5

3. diff dir1_md5 dir2_md5

Thanks rdcwayx for your reply.
Nope its not sufficient for me to just know what files are different.
I want the diff output for all files under this folder recursively i.e. the file contents difference for all files under the directory.

Perhaps you can use sshfs (fuse extension) to mount a remote directory to a local one. You need to have an SSH access to the remote machine.
After that, you can proceed in that directory as if it was local.

Thanks a lot @frans, it works perfectly fine!! Smilie
But the sad part is I am not able to convince our admin to install fuse-sshfs on our prod box Smilie

rsync(if available) should work just fine on LAN if you don't have sshfs.
Read to manual for this specific options
Code:
-n, --dry-run		    show what would have been transferred
-r, --recursive 	    recurse into directories
