rsync error -- "Protocol incompatibility" Why?

[Richard Owlett]

I had used rsync to back up a different partition with no problems.

I used that command as a model to attempt to backup another partition.

root@debian-jan13:~# 
root@debian-jan13:~# rsync --verbose  --progress --stats --recursive --times --perms --links /media/root/drescued_commo/  /media/root/backups/drescued_commo/

sending incremental file list
rsync: change_dir "/media/root/drescued_commo" failed: No such file or 
directory (2)


I then checked for existence of source:


root@debian-jan13:~# ls /media/root
17oct2017   debian64  rco sda14.bak
backups gddrescued_commo  rco1sd-card
common  good-fvwm recover-common  stretch-2nd
common-bak  jessie8-6-sda6sci-fi-dvds tomboy-testing
root@debian-jan13:~# 



The rsync man page identifies error as "Protocol incompatibility".
Under the heading "Diagnostics" speaks of problems when using ssh to 
communicate with another machine.

It later says:


If you are having trouble debugging filter patterns, then try specifying
the -vv option. At this level of verbosity rsync will show why each individual
file is included or excluded. 


I reran with -vv and received:

root@debian-jan13:~#

You are mostly correct.  However, I have one machine on which the
response to
/usr/sbin/arp -n
shows two lines with the HWaddress of the router, one with the internal
address as you said and the other with the external address.  I have no
idea what made arp see the external address.

In the above command you have "drescued_commo".

In the above output you have "gddrescued_commo" which
is not the same as "drescued_commo".

Which would explain why rsync says:
"rsync: change_dir "/media/root/drescued_commo" failed: No such file
or directory (2)"

Does that help?

*DUH* 

But that raises another question.
Why does error message identify a protocol problem after having 
correctly identified the problem as "No such file or directory".


Wouldn't "Error 3 --  Errors selecting input/output files, dirs"
be less misleading?

Thanks

man rsync says:
"EXIT VALUES
   0  Success
   1  Syntax or usage error
   2  Protocol incompatibility
[etc]
"

An *exit value* (aka exit status) is an entirely
different concept to an "error number".

Exit status is partially explained here:
http://mywiki.wooledge.org/BashGuide/TestsAndConditionals?highlight=%28exit%29%7C%28status%29#Exit_Status

The exit status = 2 mentioned in the man page has nothing
to do with the 2 in the error message
"rsync: change_dir "/media/root/drescued_commo" failed: No such file
or directory (2)"

The 2 in that message is a reference to errors reported by the standard
library of the C programming language, as explained here:

Depends on "what part" was throwing the error -- e.g. if it was ssh or
something telling rsync "no can do", then it'd be a different error.

For additional reference, when I reproduced the error locally, the exit
code (as reported by 'echo $?', run immediately after the rsync command)
was 23.

The rsync man page documents exit value 23 as being "Partial transfer
due to error", which is perfectly consistent with the behavior at hand.

(In my case the "partial" transfer consisted of transferring zero files,
out of a total of one file requested, but the principle is the same.)

Seeing with comprehension - was [ rsync error -- "Protocol incompatibility" Why?]

[Richard Owlett]

Question 1
I tried to backup another partition.
The command I *THOUGHT* I gave was:

rsync --verbose  --progress --stats --recursive --times --perms --links \ 
/media/richard/jessie8-6-sda6/  /media/richard/backups/jessie8-6-sda6/


I got a similar error message to last time (i.e. 'file not found').
The problem was a non-printing character (space?) after the first line).
Is there a graphical editor which would high-lite that "something" is there?

Question 2.
When it ran I happened to be sitting by the display and noticed things 
of the form:


var/log/lightdm/x-2.log.old
963 100%2.32kB/s0:00:00 (xfr#88022, to-chk=21/128033)
var/log/speech-dispatcher/
var/mail/
var/opt/
var/spool/
var/spool/mail -> ../mail
var/spool/anacron/
var/spool/anacron/cron.daily
  9 100%0.02kB/s0:00:00 (xfr#88023, to-chk=14/128033)


Do the lines not followed by statistics just mean "0 length files" or 
"it's just a link"?


At the end it said:



* Number of files: 128,033 (reg: 88,026, dir: 7,503, link: 32,466, dev: 
37, special: 1)*
*  Number of created files: 127,995 (reg: 88,026, dir: 7,503, link: 
32,466)*> Number of deleted files: 0

Number of regular files transferred: 88,026
Total file size: 2,837,281,458 bytes
Total transferred file size: 2,836,525,656 bytes
Literal data: 2,836,525,656 bytes
Matched data: 0 bytes
File list size: 4,717,282
File list generation time: 0.001 seconds
File list transfer time: 0.000 seconds
Total bytes sent: 2,845,135,440
Total bytes received: 1,819,035

* sent 2,845,135,440 bytes  received 1,819,035 bytes  2,837,024.89 
bytes/sec *

total size is 2,837,281,458  speedup is 1.00
root@debian-jan13:~# 



The high-lited lines caught my attention.
I take the first two seem just to report that rsync is copying 
intelligently.


I don't understand what the third is telling me when there is a 
difference between bytes sent and received. I assume it is benign as the 
was no error reported.

I got a similar error message to last time (i.e. 'file not found').
The problem was a non-printing character (space?) after the first
line). Is there a graphical editor which would high-lite that
"something" is there?


geany has quite a menu of things to enable visibility of inkless
characters.



[https://www.geany.org/manual/current/index.html#id116] seems to agree 
with you. I'll try it this afternoon.

Thanks.



Works a charm. Didn't have to read manual

Usability BUG - Which package appropriate?

[Richard Owlett]

In another thread I asked for text editor recommendations to address a 
narrowly focused problem - making non-printing (one respondent called 
them "ink-free) characters obvious.


I had specified a GUI editor.

One person suggested geany. I checked Synaptic and found it was already 
installed. Synaptic gave a "Homepage". I clicked and found that it had a 
discrete setting that addressed my problem. As it was part of Debian's 
default installation, it is the OBVIOUS solution to my IMMEDIATE 
problem. The homepage linked to suggestive pages regarding other 
problems. Already installed, solves immediate problem, and suggests that 
it solves foreseeable problems.


Case closed?
Not necessarily.

Later someone else suggested emacs.
My mental image of "emacs" was of something for a 'dumb terminal'.
I went to Synaptic searching for 'emacs'.
Got a hit for a metapaqckage - *NO* associated homepage.
Did a web search for 'emacs' which linked to 
[https://www.gnu.org/software/emacs/] which gave no relevant answers.


*HOWEVER!*
The first line stated "Emacs 26.1 is out, download it here!"
Bu [https://packages.debian.org/stretch/emacs] refers to
"Package: emacs (46.1)".

I see TWO problems:
  1. Synaptic frequently does not list a relevant homepage.
  2. [https://packages.debian.org] lacks credibility.

I underlying problems:
  1. Code creation is nirvana.
  2. Documentation is an after thought.

Why avoid "free" software? It *COSTS* to much.

I suspect I'm older than grandparents of many current programmers ;/

P.S. I've written both "Instruction manuals" and "Test procedures".

Or directly to the manual itself:

exim4 and TLS Once Again

[Martin McCormick]

After about two weeks of going down all sorts of rabbit holes
and wasting tons of time, I am at a loss trying to get
exim4 to resume the ability to send messages via the smarthost
used by our ISP.  The real trouble here is that all one really
knows is that something's broken.  It happens as soon as exim4
contacts the server.  The server immediately aborts.  It's the
ultimate "Check engine" light.  30-thousand moving parts and one
is bad.  Go figure.

It was all working fine for nearly 3 years save for a
hiccup of some kind at the ISP's site last January but this time,
it is on my end and I know that for sure.

Connections are made using TLS on port 465.

Originally, what one did was to enter the user name and
password in to a file called /etc/exim4/passwd.client as follows:

# password file used when the local exim is authenticating to a remote
# host as a client.
#
# see exim4_passwd_client(5) for more documentation
#
# Example:
### target.mail.server.example:login:password
*.suddenlink.net:marti...@suddenlink.net:deepsecret

The other modification was to a file called
/etc/exim4/update-exim4.conf.conf which is a debian-specific file
that configures the configurations hence .conf.conf.

One added a couple of lines to indicate we are using the
protocol called smtps.

After that, one ran dpkg-reconfigure  exim4-config and
selected to send mail through a smarthost and receive via
fetchmail.

It all worked until I upgraded to stretch at which point
the smarthost began dumping the connection upon the login
attempt.  At least that is what appears to happen.

Actually, I couldn't even run the reconfigure because it
complained about the protocol = smtps line and refused to build
/var/lib/exim4/conf.autogenerated file.  I had to remove that
line and then it built a dead-on-arrival conf.autogenerated file
that still allows exim4 to deliver local mail but always gets the boot
from the suddenlink server.

After a week of web searches, there is a bundle of
out-dated how-to's that used to work but nothing useful for what
to do to fix it now.

So, you might ask, How am I sending this message?

It's a proper question, all right.

There has been a program called msmtp that only does one
thing well and that is to make a smtps connection to a smtp
smarthost.

One sets up a configuration file called ~/.msmtprc and
there is where you put the smarthost's fully-qualified domain
name plus one's login credentials.

It works just fine.  You link the name sendmail to
/usr/bin/msmtp and call it via that link with the -t flag as you
pipe your message to it.  The message must be a
properly-formatted email message and msmtp makes the login to the
smarthost and delivers the message.

The trouble is that you lose local mail on the system so
you don't get all the gory detains when a shell script run by
cron blows up, etc.  I've got a few of those kinds of scripts and
it is nice to know when they misbehave.

The real problem is that there does not appear to be a
reasonable way to listen to the transaction when you need it
most.  Since the encryption is end-to-end, wireshark or some
third-party monitoring device will just spout garbage when what
one needs is a clear-text feed of what exim4 and the server are
saying to each other.  If exim4 could do that, we would know what
the last words were before the wheels came off.

At least I know the login credentials have not changed
since msmtp works but this business of manually piping a
formatted message to msmtp is for the birds but at least it beats
nothing by a hair.

exim -d -M on a message puts out about 400 plus lines of
mostly useless information, a full-color check engine light so to
speak.

Any constructive ideas are much appreciated.

Thank you.

The problem is that Thunderbird is driven by user interaction and it is 
entirely reasonable for it to access any user file. It is designed to do 
this. Maintainers cannot know in advance what users might want to do 
with their own data. This differs from system services whose expected 
file access behaviour can be defined in advance, regulated by an 
administrator, and audited by apparmor. I think that attempting to apply 
apparmor file access rules to Thunderbird is a bad idea.

I thought they'd gotten so many problems with Thunderbird under AppArmor
when they first enabled it for user-based testing that they'd wound up
disabling the Thunderbird AppArmor profile entirely, with the option for
the local admin to enable it if desired.

No, 46.1 is the Debian version number of the metapackage.
26 is the version number of a version of emacs itself. Currently,
Debian is giving us emacs24 in stable, as Dan said.

basics of CUPS troubleshooting

[Mark Copper]

Having upgraded to Stretch, a file that I need to print no longer prints
properly. (It did before.)

I am sure the difficulty is so idiosyncratic no one here will have
experienced it. So I'm not asking how to fix it specifically.  Rather I'm
looking for advice how to isolate the difficulty, generally speaking.

The file to print is a pdf file and the printer is a Zebra label printer.
The file is sent to the printer via command line, lpr. The printer is
configured via CUPS web interface. The driver is provided by CUPS (Zebra
ZPL label printer) and no external ppd file is required. The file prints
without indication of error in the cups error log.

The problem is that the orientation of the file can no longer be changed.
(Under Jessie & Wheezy, the orientation would change automatically to
accommodate the label dimensions).  Now, even when calling the
"orientation-requested" option, the orientation cannot be changed 90
degrees, instead it just flips 180 degrees.

So I'm wondering what changed? Can I somehow isolate the change to a file?
Is there documentation what changes might have been made to the file
somewhere?

Thanks for reading.

You are mostly correct.  However, I have one machine on which the

Thinking of it, a router following the "weak host" model (like Linux 
does) can advertise any local address on any interface. It can be tested 
with arping. However I am failing to imagine any plausible scenario 
which could lead a host on the internal LAN to have the router's 
external IP address in its ARP cache. It means that either :

- the host sends an ARP query for the router's external IP address
- the router sends an ARP query to the host from its external IP address

File managers show files and directories in reverse order.........

[Charlie S]

Hello Everyone,

Suddenly my file managers show the files in reverse order to
the norm, i.e directories on top and individual files beneath.

Don't know how it was accidentally done?

Using FVWM - Debian Stretch

Any clues where I might configure this to return it to what is was
would be appreciated.

TIA

Which file manager are you using? Thunar (the default for Xfce) has a 
checkbox option Edit / Preferences / Display / "Sort folders before files".


Thunar also allows you to change the sort order by toggling the "\/" 
(descending) or "/\" (ascending) at the end of the column heading label, 
but I think your problem is more like that fixed by the checkbox above.

Thanks for your prompt answer Ben. I use MC and that's fine. 

But when I go Ctrl-O when in Kate or Lyx the order is reversed. Can't
get an answer from the Lyx list. It must be a file manager accessed by
these two.

Libreoffice and Okular don't reverse the order.

When the window opens there is no option other than list view - detail
view or new folder. Very sparse.

I might have to set the file-manager in my profile or .bashrc, but
don't know the way to do that.

Thank You,
Charlie

That is 100% of the diagnostic help.  With the -d flag, that part
still doesn't change.  All one gets with the -d flag is lots of
file descriptors opening and closing.

The only thing the log seems to show is that the
authentication process goes wrong instantly but no clue whether
or what causes that.

I have looked in the man page and the word smarthost
doesn't appear.

/usr/share/doc/exim4-base/

has nothing with one file briefly mentioning a smarthost but no
best practices or sample configuration examples.

I also know experimentally that no part of
/etc/exim4/passwd.client appears in the
/var/lib/exim4/config.autogenerated file so exim4 must give that
out on demand or maybe I should say it is part of the output
generated during the session.

Either the passwd.client file needs something else or
another file needs modification as the user name and password are
known to be good.

The experiment was to generate a new conf.autogenerated
file after modifying passwd.client and using diff between it and
the previous config.autogenerated file.  They were a perfect match.

If there is a document somewhere describing this setup
for exim4.80 or above, it should be useful as the changes
apparently took place around version 4.79 or 4.80 and this
version is 4.89.

The fact that you are reading this message is proof that
the user ID and password still work with smtp.suddenlink.net,
just not in exim4 yet.

Thank you.
