Testers for new ssh-*-config scripts wanted!

[-- Attachment #1: Type: text/plain, Size: 1449 bytes --]

Hi,

is anybody here willing to give my new ssh-host-config and ssh-user-config
shell scripts a thorough test?  I tested them by myself but I have this
nagging feeling I missed something important.

The important changes:

- On NT, try to set permissions on files and directories to a useful value.
- On NT, try to set ownership on files and directories to a useful value.

Only in ssh-host-config:

- Write the /etc/services entries for ssh now with CRLF lineendings.
- Remove the code to accomplish old style installations, with "old
  being older than roughly 3 years.
- /etc/ssh_config and /etc/sshd_config are not hardcoded here-scripts
  in the ssh-host-config script anymore, but they are copied and
  modified from ssh_config and sshd_config files in /etc/defaults/etc.
  This allows to accomodate changes in the vanilla scripts without
  having to change the shh-host-config script.
- On NT, always set ownership of various files to SYSTEM, if sshd
  has been installed as service.

Both scripts are attached.  When testing the new "copy config files
from /etc/defaults/etc" functionality, please think of copying the
ssh_config and sshd_config files (if possible the vanilla versions)
to /etc/defaults/etc first.

Feedback and patches welcome and thanks in advance,
Corinna

RE: Testers for new ssh-*-config scripts wanted!

[Philippe Torche]

Script ssh-host-config works for me, but when I've entered the CYGWIN env
var, I've do a error and type "ntser", then backspace and then the correct
"c" caracters.
Thus CYGWIN key in the registry has now "ntser\x08c" instead of "ntsec"!
This is caused by the read command!

Thanks.

Yeah, but that's not a fault of the script but of the shell.  Nothing
I can do about in the script.  Except if I require the script to run
under bash instead of sh, to allow readline support.

Would that be acceptable?  I have attached a new version of ssh-host-config
to this mail, which requires bash now.  If that's not ok, it's easy to
revert again.

I've also attached the two vanilla files ssh_config and sshd_config to
put into /etc/defaults/etc. This should simplify testing.

Changed in this version of ssh-host-config:

- Require bash.
- Remove annoying backslashes when echoing a bang (!).
- Allow /var/log/lastlog to be a directory (But that can again create
  problems with permissions, Pierre!)

Please don't forget to test ssh-user-config, too.  Thanks.

You know, PGA and PTC.  See wtf ;-)

Thanks to all testers,

RE: Testers for new ssh-*-config scripts wanted!

[Philippe Torche]

Nope,

read from bash don't reconize control caracters without -e parameter:
$ read _cygwin
Ntser[Backspace]c
$ echo $_cygwin | od -t x1
0000000 6e 74 73 65 72 08 63 0a
0000010

BUT OK with "-e"

$ read -e _cygwin
Ntser[Backspace]c
$ echo $_cygwin | od -t x1
0000000 6e 74 73 65 63 0a
0000006

Erm... when I use bash, read always recognizes the backspace correctly.
*dig dig dig*
Even better, when using /bin/sh (ash), I don't have your above problem
either.  I can change the string and no control code shows up in the
variable's value.  What's different on your machine?

Sorry but,

The doc of bash explains this behavior (help read). You can experiment the
same think on Redhat per exemple. And don't forget to use "echo $_cygwin |
od -t x1" to show what is stored in the variable.

Have a nice cygweek, Philippe.

I did, of course.  Backspace works w/o -e, too.

I'll use -e nevertheless to allow complete readline support.

OK.  Thanks!  I will extract the contents
of the here documents and put them in
/etc/defaults/etc/sshd_config and 
/etc/defaults/etc/ssh_config.  I don't
trust my files in /etc/ to be vanilla
at this point.

She meant the ones you would have in /etc if you had previously
run the old ssh-host-config script.  If you had not, they can be found
embeded in the old ssh-host-config script as mentioned here:

RE: Testers for new ssh-*-config scripts wanted!

[Harig, Mark]

I have OpenSSH 3.7.1p2-1 installed, but I
do not have the 'ssh_config' or 'sshd_config'
template files that the 'ssh-host-config' script
expects.  Am I missing a step here that I should
have taken to generate these files?

I ran 'cygcheck -f /etc/defaults/etc/ssh_config'
and searched the Cygwin Package List at
http://cygwin.com/packages, but both searches
did not find any packages that should contain these
template files.

RE: Testers for new ssh-*-config scripts wanted!

[Harig, Mark]

I will read these two scripts "soon".
This won't be a thorough test, but it
will be another set of eyes reading the
code.

Of course, a much better candidate for
reading (and testing the scripts would
be someone who is knowledgeable about
OpenSSH.  I'm simply a user of it.
