I am able to remote edit on all of my remote systems except one.  On that particular system, when I login, it shows that it's the correct file in the buffer, but the buffer is blank.  If I do a 
directory listing, I get the same blank buffer.  The verions of emacs is 22.3.1.  The OS on the remote system is Ubuntu 8.04.  

 

If I create a new file and try to save it on the remote server, it says "No such file or directory", even though the dirctory is correct.
