Re: [BackupPC-users] Unexplained Error Code 255 - BackupPC

@Craig Barratt<mailto:cbarr...@users.sourceforge.net> that was indeed the 
problem.  I was able to get my ssh to use password-less login and sorted out 
the list of known_hosts issue and that seemed to do the trick.

Failed to add the host to the list of known hosts 
(/home/backuppc/.ssh/known_hosts).

In addition to password-less login, this error is also a problem.  It probably 
means your permissions on ~backuppc/.ssh/known_hosts are wrong.  Without the 
client being in known_hosts, ssh will prompt every time to be sure you want to 
proceed.

So there are two prompts (ok to proceed & password) you need to get rid of.

Thanks @Craig Barratt<mailto:cbarr...@users.sourceforge.net>.  Looks like it is 
a little bit of both.  When I turned the firewall completely off and ran your 
command, I got the below.  However, I was never able to get in as it is asking 
for a root password for Windows and when I enter my password, it rejects it.  
Strange, as when I run this command as backuppc “ssh akibu@akibu-desktop” and 
enter my Windows password, it allows me into the Windows computer.

figure out whether sshd is running on your client, or whether the windoze

What output do you get when you run this command (replace -q with -v, and 
redirect stdin from /dev/null):

/usr/bin/ssh -v -x -l root akibu-desktop /usr/bin/rsync --server --sender

Akibu,

It looks like the connection terminates immediately.  We need to figure out why.

If you run the exact ssh command as the backuppc user, do you get an error or 
any output?

su backuppcUser
/usr/bin/ssh -q -x -l root akibu-desktop /usr/bin/rsync --server --sender 
-svvvlHogDtprce.iLsf

If you don't see any output, hit ^D and you should get an error like this:

rsync: on remote machine: (null): unknown option
rsync error: syntax or usage error (code 1) at main.c(1634) [server=3.1.1]
[server] _exit_cleanup(code=1, file=main.c, line=1634): about to call exit(1)

Next, are you sure that the directory /mnt/j/Favorites on akibu-desktop exists?

Thanks @Craig Barratt<mailto:cbarr...@users.sourceforge.net>.  I don’t get any 
output or error whatsoever when running the command you suggested.  I tried 
hitting ^D but still did not get an error or output.  (btw, is that a 
Ctrl+Shift+D or Ctrl+D (neither produced an output though)).  Thanks.

Subject: Re: [BackupPC-users] Unexplained Error Code 255 - BackupPC

Akibu,

It looks like the connection terminates immediately.  We need to figure out why.

If you run the exact ssh command as the backuppc user, do you get an error or 
any output?

su backuppcUser
/usr/bin/ssh -q -x -l root akibu-desktop /usr/bin/rsync --server --sender 
-svvvlHogDtprce.iLsf

If you don't see any output, hit ^D and you should get an error like this:

rsync: on remote machine: (null): unknown option
rsync error: syntax or usage error (code 1) at main.c(1634) [server=3.1.1]
[server] _exit_cleanup(code=1, file=main.c, line=1634): about to call exit(1)

Next, are you sure that the directory /mnt/j/Favorites on akibu-desktop exists?

Craig

Sorry, I was really careless when I looked at it -- I assumed it was a 
log of rsync, which would have been somewhat useful, rather than a trace 
of ssh, which would probably only be useful in tracking down ssh 
handshaking issues.  From a cursory glance, it looked like you were 
attempting to back up /dev/urandom rather than demonstrate that ssh was 
trying to read from /dev/urandom for entropy gathering as part of its 
encryption.

(Err.

What, exactly, are you trying to resolve? I suspect you've gotten no answer 
because many people looked and said, well, that's obvious, don't back up the 
/dev directory, because it's dynamically created. While you're at it, don't 
back up /proc, /sys, or /tmp.)

Also without extraenous output? You seem to be using rsync over ssh, and rsync 
is quite fussy about messages that it does not expect. As a rule of thumb, to a 
Linux computer,

% ssh clientcomputer true

should immediately display the next prompt as indicated above, i.e. nothing 
extra, not even blanks or newlines. For Windoze, your mileage may vary, but it 
probably won't. The actual invokation used by BackupPC (or rather rsync_bpc) 
might include extra options to ssh, e.g. -q -x -l someuser … include those when 
testing.

- Correct, Holger.  I am using rsync over ssh and ssh seems to

work without a problem. When I run the test you suggested: “$ssh targetcomputer 
true”, I merely get the prompt in response “$”. Strace seems to confirm that 
ssh is working correctly as when I ssh into the targetcomputer from the command 
line, and while running running strace on the targetcomputer, all seems to work 
as expected. In addition, when I rsync into the targetcomputer from the command 
line, rsync appears to work just fine.

However, when I use the backuppc program to rsync into the very same 
targetcomputer, I get the Unexplained Error Code 255 message. Below shows the 
ssh strace when I started a manual backuppc backup of some files on the 
targetcomputer, if that helps. My log level is up to 9, but not much 
information is being generated. I am unclear of how to diagnose as I am not

Re: [BackupPC-users] Unexplained Error Code 255 - BackupPC

[Craig Barratt via BackupPC-users]

The strace is showing the dynamic linking during startup of ssh, which
isn't particularly relevant.  It's not showing the files being backed up.

What we are missing is the log output from XferLOG.  That has the more
detailed information (eg, exact rsync / ssh args).  Can you send that
please?  You'll find it in the per-PC backup directory, eg:
/data/BackupPC/pc/clientName/XferLOG.bad.z.  Use BackupPC_zcat to
uncompress it.

wow ... where did you get that version from?

version 4.1.1.


When I start a backup, it appears to properly connect to my Windows

without problem.


Also without extraenous output? You seem to be using rsync over ssh,
and rsync is quite fussy about messages that it does not expect. As a
rule of thumb, to a *Linux* computer,

   % ssh clientcomputer true
   %

should immediately display the next prompt as indicated above, i.e.
nothing extra, not even blanks or newlines. For Windoze, your mileage
may vary, but it probably won't. The actual invokation used by
BackupPC (or rather rsync_bpc) might include extra options to ssh,
e.g. -q -x -l someuser ... include those when testing.

- Correct, Holger.  I am using rsync over ssh and ssh seems to
work without a problem.  When I run the test you suggested:  "$ssh
targetcomputer true", I merely get the prompt in response "$".  Strace
seems to confirm that ssh is working correctly as when I ssh into the
targetcomputer from the command line, and while running running strace
on the targetcomputer, all seems to work as expected.  In addition,
when I rsync into the targetcomputer from the command line, rsync
appears to work just fine.

However, when I use the backuppc program to rsync into the very same
targetcomputer, I get the Unexplained Error Code 255 message.  Below
shows the ssh strace when I started a manual backuppc backup of some
files on the targetcomputer, if that helps.  My log level is up to 9,
but not much information is being generated.  I am unclear of how to
diagnose as I am not that versed in linux.  Any help would be

Also without extraenous output? You seem to be using rsync over ssh, and
rsync is quite fussy about messages that it does not expect. As a rule of
thumb, to a *Linux* computer,

   % ssh clientcomputer true
   %

should immediately display the next prompt as indicated above, i.e. nothing
extra, not even blanks or newlines. For Windoze, your mileage may vary, but
it probably won't. The actual invokation used by BackupPC (or rather rsync_bpc)
might include extra options to ssh, e.g. -q -x -l someuser ... include those
when testing.

Regards,
Holger

@Craig Barratt<mailto:cbarr...@users.sourceforge.net> The rsync on the Windows 
computer is version 3.1.1 and on the Linux computer is 3.1.2.  Thx.

What version of rsync are you running on the client?

Another user reported a problem that the default cygwin rsync setup on 3.x 
doesn't allow remote charset settings.  BackupPC 4.x uses the --iconv rsync 
option, which will fail without a clear error message.

You should add "charset = utf-8" to the client's rsyncd.conf to see if that's 
the issue.

(Since it fails very early in the transfer, I'd recommend you add "-vvv" to 
$Conf{RsyncArgs}.)
