that wouldn't cause an EOF on stdin... which is what rdiff-backup saw...

hopefully the tcpdump will show something... 

because your local rdiff-backup is seeing an unexpected EOF and the remote 
rdiff-backup is also seeing an unexpected EOF i think the problem is 
likely the various processes and network between the two... so you may end 
up having to strace the sshd, and even the shells (pstree -Alpu will help 
you find all the involved processes).

heh, no :)  i didn't even put in an install rule...

just type "make" to create the binary... and "nroff -man circular.1 | 
less" to read the man page... there's an example on the man page.

or install them if you want:
        % install circular /usr/local/bin
        % install -m 644 circular.1 /usr/local/man/man1
