Re: [Mondo-devel] [MondoRescue] #784: mondoarchive or mondorestore SEGV with tape management

Steven M. Schweda
   Any news?  (Has anyone actually tried this program using a tape
drive?)

>  Is part of 3.2.2

   Thanks.  Now it gets all the way to asking for the tape block size
before exploding.

deb74# mondoarchive --version
mondoarchive v3.2.2-r3578
See man page for help

deb74# mondoarchive

Backup to: Tape drive

What is the /dev entry of your tape streamer?
      /dev/st0

What is the block size of your tape streamer?
      32768 [default]  "OK" is followed by a screenfull of white text on
a blue background (some lost, I believe):

                 Log file: /var/log/mondoarchive.log
                                                    Mondo has aborted.

   The process does not exit, and "kill -TERM" leaves the
terminal/emulator in a modified state (colors, intr = <undef>; quit =
<undef>; eof = ^A; susp = <undef>; lnext = <undef>; -icrnl, -opost,
opost, -icanon, -iexten, -echo, noflsh, -echoctl, -echoke, ...).

   An actual exit handler which restored the original terminal settings
might be a good thing.

   And, before the program explodes, my Mac xterm shows garbage for box
borders in the char-cell GUI, which, I assume, were supposed to be
line-drawing characters.

   Another, minor annoyance: When I see a question like "What is the
/dev entry of your tape streamer?", I assume that the questioner wants
the part of the answer which is not already known.  That is, in this
case, "st0", not the whole device path, "/dev/st0".  Naturally, if the
victim specifies "st0", the program output is the usual (unhelpful):

See /var/log/mondoarchive.log for details of backup run.
Checking sanity of your Linux distribution
Done.
Execution run ended; result=1
Type 'less /var/log/mondoarchive.log' to see the output log

   Admittedly, there is a useful message hidden in that mess (if you can
find it):
INFO: ls: cannot access st0: No such file or directory

   A helpful program might try "/dev/<user_input>" if plain
"<user_input>" does not exist.  Or, the question could be phrased more
helpfully, for example:
      Tape device path (e.g.: /dev/st0 or st0)?
Just a thought.

   Old news: http://trac.mondorescue.org/register still fails:

Register an account
Error

The password file could not be updated. Trac requires read and write
access to both the password file and its parent directory.

   As usual, if you need more info, please let me know.

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
