Issues Authenticating - OpenSolaris

[The_Nerd]

I've managed to overcome a few hurdles but still no luck running neatx
on OpenSolaris.

I've compiled it against GNU/Linux world binaries, I'm using OpenSSH
(because SunSSH seemed to give it problems) but I'm stuck again.

I get the following output from the NX Client 3.4.0:
NX> 203 NXSSH running with pid: 3252
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files
NX> 285 Setting the preferred NX options
NX> 200 Connected to address: 192.168.1.115 on port: 22
NX> 202 Authenticating user: nx
NX> 208 Using auth method: publickey
HELLO NXSERVER - Version 3.3.0 - GPL
NX> 105 Hello nxclient - version 3.3.0
NX> 134 Accepted protocol: 3.3.0
NX> 105 Set SHELL_MODE: SHELL
NX> 105 Set AUTH_MODE: PASSWORD
NX> 105 Login
NX> 101 User:
NX> 102 Password: **********
NX> 500 Internal error
NX> 999 Bye.
NX> 404 ERROR: wrong password or login.
NX> 280 Exiting on signal: 15

I've been able to authenticate just fine by doing:

will@opensolaris:~# su - nx
HELLO NXSERVER - Version 3.3.0 - GPL
NX> 105 login
Login
NX> 101 User: will

NX> 102 Password: **********
NX> 103 Welcome to: localhost user: will
NX> 105

So I assume the problem is with authentication coming in from SSH and
passing the process off to neatx. Logging, despite my best efforts,
does not seem to output anything, anywhere.

Anything else I can check or try?

This will cause a bunch of debug logging, which should detail the
underlying problem.

The lack of logs is the biggest issue right now - without those, we
can't figure out what's going wrong. Neatx logs everything under the
USER facility. On linux at least, that means /var/log/user.log. If you
don't see anything there, have a look at /etc/syslog.conf (just
guessing) for any lines beginning with "user.".

Got the logs! For anyone using OpenSolaris, they'll be in /var/adm/
messages

I'm no expert but it looks like pexpect is having problems opening /
dev/tty. I can confirm that /dev/tty exists but I'm unsure of how
neatx is interacting with it. I'll try to dig though the code and run
the auth commands manually. If anyone can make any better sense of
what's going on, I'd love the help!

Indeed, pexpect's is getting "file does not exist" when it tries to
open /dev/tty.

/dev/tty is a special file that always refers to the current process's
tty. In the above, i'm guessing that for some reason neatx doesn't
have a tty assosciated with it. Or possibly your version of pexpect
has a bug relating to OpenSolaris. Here's the comment at the top of
the function from the version i'm using:

def __pty_make_controlling_tty(self, tty_fd):
"""This makes the pseudo-terminal the controlling tty.
This should be more portable than the pty.fork() function.
Specifically, this should work on Solaris.
