[9fans] Plan 9 hg with private repositories

[9fans] Plan 9 hg with private repositories

[John Floren]

Hi

So I'm trying to clone a private repository I just created on
bitbucket. This is what I see:

jerq% hg clone https://<username>@bitbucket.org/<username>/<repo>/
destination directory: <repo>
http authorization required
realm: Bitbucket.org HTTP
user: <username>
abort: could not import module msvcrt!

If I try with ssh instead:
jerq% hg -v clone ssh://hg@bitbucket.org/<username>/<repo>/
running ssh hg@bitbucket.org "hg -R <username>/<repo>/ serve --stdio"
abort: no suitable response from remote hg!


Has anyone else tried this?

Surely there is a version of https support
that doesn't involve msvcrt?  That's a
Windows DLL.

Presumably this is because ssh is sshv1
but bitbucket requires sshv2.

I have hacked up python's getpass.py to do password-prompting for Plan
9, so I can now do https authentication. I'll send the modified
getpass.py to 9fans after I've made sure it works ok. My Python-fu is
not great, so right now it just always assumes you're using Plan 9
(bad).

I did 'bind /bin/openssh/ssh /bin/ssh' before running this hg command,
but to no avail. I do have my public keys uploaded, so there shouldn't
be a problem there... however now that https works I don't necessarily
need the ssh support.

On a different note, I just tried "hg pull", which was successful, but
"hg update" gives:
abort: could not import module mpatch!
(did you forget to compile extensions?)

Have I screwed up my mercurial installation in some way?

By the way, I realized that hg on Windows file systems does not like
the following files:

    bin/"
    bin/""

Clone/pull work fine.  You just can't successfully update to actually
get the bits into a working system.

I tried re-compiling and starting over, and it seems like somewhere
along the way the updating problem went away. I've written up a quick
document about how I did things, which can be found at
/n/sources/contrib/john/hg-howto.txt. If somebody else can take a look
at it, try the procedure, and let me know how things work, that would
be great.

Correct me if I am wrong, but an sshv2 server is also providing sshv1
too. Maybe when the Plan 9 ssh client is facing sshv2, instead of
shutting down with an error, it should try sshv1, or wait until its
offered, i am unsure about the mechanism here. Just an idea, I am
really not an expert here.

I vaguely remember reading that some ssh software would refuse to work
with ssh v1 by default because v1 is so insecure.

OpenSSH can support v1 and v2, whether it is configured to is a local option.

man sshd_config

  :
 Protocol
             Specifies the protocol versions sshd(8) supports.  The
possible values are ‘1’ and ‘2’.   Multiple versions must be
             comma-separated.  The default is “2,1”.  Note that the
order of the protocol list does not indicate preference,
             because the client selects among multiple protocol
versions offered by the server.  Specifying “2,1” is identical
             to “1,2”.

  :

The /etc/ssh/sshd_config supplied by default with many (most?) linux
distributions seems to be configured to only allow v2.  If you're the
administrator or on good terms with the admin. you may be able to
reconfigure your SSH to allow v1 connections, otherwise get to work on
the p9 ssh v2 port.

Many times you must turn v1 on, but it's available.  It's off by default due
to it being insecure.

If I"m recalling correctly, SSHv1 is insecure only if the remote server is
untrusted. Or am I not recalling correctly?

When you connect to the SSH server, if it is willing to
accept version 1 or 2 it says 1.99 as its version.
If it is only willing to accept version 2, it says 2.

$ dial 'tcp!bitbucket.org!ssh'
SSH-2.0-OpenSSH_5.1p1 Debian-5

That's a 2.0-only banner on the site in question,
which is not under John's control.

I believe you're correct and that server fingerprinting was introduced  
in v2. I asked some friends of mine about it and they said the  
principal issue is that it uses CRC for the packet checksum, which  
makes it not particularly hard for a third party to inject packets  
into your connection. Also, there are theoretical attacks that allow  
the session key to be recovered. One of my friends also said it only  
supported 3DES, but I'm not convinced that's a cryptological weakness  
in and of itself, nor that designing a new protocol with plug 'n play  
crypto is genius either, since I think a lot of the complexity in SSH  
v2 comes from its configurability, the effect that has on connection  
setup, as well as silly optional features like connection sharing and  
whatnot. (I use that silly feature all the time but I don't think I  
would have offered to build it into the protocol.)

i found where the 0x20 came from.  it should be 20, not 0x20.
anway, it comes from ahci:/^mkalist.  l->flags specifies that
the fis is 0x5 dwords = 20 bytes.  either i missed the explaination in
the ahci docs about why this is or it's a bit magic.

I just hit this problem again with a clean install of the mercurial
and python from sources (and my package tool .. but I don't think it's
the problem).

ratrace helped.

Ow, that hurt, did it not?

Basically, it found getpass, did not find termios, then went looking
for some MS VC runtime. Yuck.

The code (getpass.py):
# Bind the name getpass to the appropriate function
try:
    import termios
    # it's possible there is an incompatible termios from the
    # McMillan Installer, make sure we have a UNIX-compatible termios
    termios.tcgetattr, termios.tcsetattr
except (ImportError, AttributeError):
    try:
        import msvcrt
    except ImportError:
        try:
            from EasyDialogs import AskPassword
        except ImportError:
            getpass = default_getpass
        else:
            getpass = AskPassword
    else:
        getpass = win_getpass
else:
    getpass = unix_getpass

Wow, that hurt too.

So, it's trying to get a password, as it is an https import, so it
pulls in getpass, which pulls in termios, and it's failing, and the
only reasonable thing to do when you can't find a unix package is to
try to use an MS VC runtime package and, when that fails, bail out
with one of the worst error messages one can imagine.

Wow, GRRoss.

Anyway, that is why you get that utterly useless error message:
because you're not unix. It just tells you that the error is that you
are not windows. Clear?

I gave you the work around 2 months ago...
the python code is broken, their default doesn't default...

echo 'getpass = default_getpass' >> /sys/lib/python/getpass.py

I think you should be able to replace getpass.py with
http://plan9.bell-labs.com/sources/contrib/john/getpass.py; I added
plan9_getpass last summer and it seemed to work.

Yep, I confess: I forgot.

I was more trying to test what goes wrong with a clean install, and
had forgotten the fix!

that's kind of a heavy duty fix ... is there one that is simpler somehow?
