[Box Backup] EVP Error while running bbackupd

[Peter Buecker]

Hello,

I recently installed boxbackup-0.09 on a OpenBSD-3.6-stable system 
(called backup-server here). I set up 7 backup-clients. However, only 6 
work as expected.

When running bbackupd on the remaining one (host3), bbackupd complains 
about failing to decrypt (via syslog):

"Dec 21 16:31:11 host3 bbackupd[13553]: SSL err during Read: 
error:06065064:digital envelope routines:EVP_DecryptFinal:bad decrypt
Dec 21 16:31:11 host3 bbackupd[13553]: SSL err during Read: 
error:06065064:digital envelope routines:EVP_DecryptFinal:bad decrypt
Dec 21 16:31:11 host3 bbackupd[13553]: Exception caught (5/6), reset 
state and waiting to retry..."

At the same time, the backup-server logs the following:
"Dec 21 16:31:11 backup-server bbstored[1147]: in server child, 
exception Connection Protocol_Timeout (Probably a network issue between 
client and server.) (7/41) -- terminating child"



The certificate request for host3 has been signed on backup-server and 
copied to /etc/box/bbackupd/ on host3 in the same way we did it on the 
other 6 hosts.
Connectivity is okay, since I can telnet to port 2201 on backup-server 
from host3. I can also run bbackupquery on host3. It logs in perfectly:

"bash-3.00# bbackupquery
Box Backup Query Tool v0.09, (c) Ben Summers 2003, 2004
Using configuration file /etc/box/bbackupd.conf
Connecting to store...
Handshake with store...
Login to store...
Login complete.

Type "help" for a list of commands.

query >"

Upon typing 'ls', it exits with the following error message:

"query > ls
Exception: Cipher EVPFinalFailure (5/6)
bash-3.00#"

I tried using the debug-build of bbackupquery and bbackupd, to no avail. 
I also deleted /etc/box and rerun bbackupd-config to generate new keys 
and new configuration files, without success.
Any suggestions on what might be going wrong with this machine?

Thanks,
Peter Buecker
