[9fans] Aquarela suicide

[tt.gustavsson]

It might be a bit odd to export plan9 filesystem to my windows
machine. Though I have put the large disk into the plan9 system
and the little disk (10Gb) into the windows machine. I'd just want
some more space on the windows machine.

Probably my problem is because I actually run aquarela on the auth server and
connect to the same machine for authentication?

Thanks anyway

True, but with the bug fixed in aquarela, he would
still not have authenticated successfully because
of a bug in network configuration.

That's two bugs.

cat /mnt/factotum/ctl and you may see home.hm.

Re: [9fans] Aquarela suicide

[geoff]

Is home.hm (or its IP address) in a plan9.ini or nvram file (partition
or plan9.nvr file)?

[tt.gustavsson]

At last, I got it to work.

The problem was my configuration of the network.

aquarela tried to find the auth server for the local network
which I once called home.hm,
adding authdom = home.hm to the ipnet 192.168..... in /lib/ndb/local
made it work and aquarela found the auth server.

Now, I can't find where the home.hm domain comes from, I must have
specified it somewhere, but can't remember where, it is not in the files local or common?

I traced the problem with the (excellent) program /sys/src/cmd/auth/challenge.c

I did reset the inferno/pop secret, but unfortunately no change in aquarela behaviour

But the auth log might be of interest, not a single line about mschap failing.
(though logging about other activities)

When I look at the /rc/bin/service.auth/il566 and
                                                             tcp567
and both start /bin/auth/authsrv -d $3

If I have understood it right this means that the debug messages should appear from
authsrv, and the conclusion would be that aquarela does not even talk to the auth server
at all, right?

Re: [9fans] Aquarela suicide

[Russ Cox]

the mschap stuff comes straight from the auth server.
aquarela should not be crashing (it's definitely a bug
that it is), but the bigger problem is the inability to
get the mschap challenge from the auth server.

maybe there is something interesting in /sys/log/auth
on the auth server?

try running passwd to reset your password and
make sure you say "y" when it asks whether the
inferno/pop secret should be the same.  that's
what gets used for mschap, in contrast to the
plan 9 key that gets used for drawterm.

the fact that there are two keys is historical accident
more than anything else.

[tt.gustavsson]

The only thing I can see in the log file is what you also noticed
a problem with authenticating mschap.

The log is in my first post.

I believe there is something wrong with the authentication as
pointed  out to me by nigel roles.

Am I doing something wrong on the XP machine?

I am trying to map Z: to \\192.168.....\local, and
I provide the login bootes and password that works when connecting with drawterm.
Aquarela is being run from my combined cpu,auth,fileserver.

Also, is factotum involved in the authentication process, i tried to add a key for mschap,
but it seems not possible.


Thanks

Re: [9fans] Aquarela suicide

Is there anything interesting in the log file
if you turn on logging?  It looks to me like
an smbnegotiate message failed (couldn't
get mschap challenge) and then windows
went ahead and sent an smbcomsessionsetupandx
anyway.

Next time aquarela suicides, try this, to get a stack trace:

and let us know what it says.  Thanks.

Re: [9fans] Aquarela suicide

[Steve Simon]

Hi

I just tried aquarela with Win XP SP1 and it worked fine:
read / write delete /chmod/ rename files and dirs.

I tried it at home with NT4 SP6 and had more trouble. I am half way through
fixing this and adding the features my cifs client requires
for interoperability.

Note, for authentication to work Aquarela needs to be run as bootes,
Ie envoke it from cpurc, or, cpu to your file/auth/cpu server as bootes

	cpu -u bootes -h server-hostname -c aquarela

If you dont do this it won't work but I have never seen it suicide
(though I'am not a heavyweight user).

-Steve

[9fans] Aquarela suicide

[tt.gustavsson]

I did not see the beauty of plan9,

authentication of aquarela uses factotum right?

proto=mschap ...

But when I try to add a key

auth/factotum -g 'proto=mschap server=cpu1 user=abc123 !password=abc123'

Factotum complains with:

proto mschap doesn't take keys

Have I misunderstood the authentication again?

In the factotum manual there is a section about mschap among other protocols:

Apop, cram, chap, and mschap, require a key with a proto attribute whose value matches
the protocol, in addition to server, user, and !password attributes; e.g.


proto=apop server=mit.edu user=rsc !password=nerdsRus

I would not do either. Since you have NT, you can avoid the need
for Netbios as aquarela answers on 445 (and probably needs an option
to make it answer netbios calls as well). Also, NT passwords are
insecure enough as it is, without using cleartext. Plan 9 won't
tolerate that anyway, so you have to use NTLM passwords.

Your problem is (half) explained by...

IIRC that's because aquarela had a problem with contacting the auth server.
Presumably I didn't handle the condition correctly, and dereferenced
a null pointer later.

PS I may be responsible for aquarela, but regretably I don't
have a Plan 9 network on which I could debug it for you just right now.

Re: [9fans] Aquarela suicide

[boyd, rounin]

so, you're drawtermed into plan 9 and you want to access local windows files?

[9fans] Aquarela suicide

[tt.gustavsson]

Hello

I am trying to connect to a plan9 server from win xp SP1,
with aquarela v0.5 running the plan9 machine.

I am trying to map a network drive to \\192.168.10.26\local
I have tried with using bootes, glenda, but
everytime aquarela traps with:
aquarela 260: suicide: sys: trap: fault write addr=0x0 pc=0x00008d2b

I have made the workgroup of the windows xp machine to PLAN9 , because
aquarela defaults to this.

Have I made some erronous assumption? Can I connect with any account on
the PLAN9 machine. It is set up as a combined CPU,AUTH, FILE server with
fossil as file system. the sharename local will point
to the root of the filesystem / , right?

On the windows xp machine I have made sure netbios over tcpip is enabled,
also I have enabled cleartext password, I thought that may have  helped.

Thank you
