[BackupPC-users] fileListReceive failed, ruled out a dirty shell, what next?

[Troy D. <tr...@me...>]

Hi all,

One of the machines I backup stopped syncing last week. The machine  
running BackupPC and the system being backed up are both running  
Fedora Core 4. I upgraded the BackupPC machine from FC3 to eliminate  
the possibility of version conflicts with rsync, but it's worth  
noting that before the upgrade I was using an rsync compiled from  
source, I'm not using the same RPMs on both sides.

The most confusing part is that another system is still getting  
backed up successfully, and it's running FC2 and using rsync compiled  
from source (2.6.3 compared to 2.6.8 on the server and failing system).

I had some time to trying the standard resolution methods I found via  
Google, but no joy and I'm at a loss. I've changed the remote  
machine's domain name to "remotehost" for sake of anonymity, but  
below is my shell session:

[backuppc@local ~]$ ssh -l root remotehost /bin/true > out.dat
[backuppc@local ~]$ cat out.dat
[backuppc@local ~]$ ls -alh out.dat
-rw-rw-r--  1 backuppc backuppc 0 Jun 14 12:09 out.dat
[backuppc@local ~]$ /usr/bin/ssh -q -x -l root remotehost /usr/bin/ 
rsync -vv --server --sender --numeric-ids --perms --owner --group -- 
devices --links --times --block-size=2048 --recursive --exclude=/tmp  
--exclude=/proc --exclude=/sys --ignore-times . /
[server] add_rule(- /tmp)
[server] add_rule(- /proc)
[server] add_rule(- /sys)

(Server) Protocol versions: remote=168430090, negotiated=29
protocol version mismatch -- is your shell clean?
(see the rsync man page for an explanation)
_exit_cleanup(code=2, file=compat.c, line=64): entered
rsync error: protocol incompatibility (code 2) at compat.c(64)  
[sender=2.6.8]
_exit_cleanup(code=2, file=compat.c, line=64): about to call exit(2)


Any hints on how to troubleshoot this further?

Thank You,
Troy
