[gvd-users] rexec instead of rsh? preferences file? Inferior debuggers

[Rosenzweig, Daniel Z (Dan), NNAD]

Thanks. My thoughts were to use Reflection's rexec (as opposed to Winnt 4's
rexec). Reflection's rexec has a -n option, which allows you to specify a
password file. The problem is, that it must be supplied AFTER the hostname,
so it doesn't seem to jive with the way that the program is creating the
call to rexec. I noticed that I don't get a logfile, even at log-level 4
once I created the preferences file... I didn't even get any UI errors... it
just exited, and that's it. 
( Usage:  rexec <host> [-l username] [-n <password.fil] <command>   )

The reason why I'm trying rexec is that gvd is trying to rsh (from PC) to
Machine B, which has my home directory mounted from Machine A.... When I rsh
to Machine B directly, it doesn't find my .rhosts file, and doesn't let me
in (rsh into Machine A is ok, but I don't have gdb running on that machine,
only xdb, so I can't test if it works there). I'll post this on an HPUX
group to see if they can help.

The log-level 4 msgs I get are (since it couldn't log in):
[1] -> "set prompt (gdb) \n"
[1] <- "RSH4000: Remote error: remshd: Login incorrect.\r\n"
       "\r\n"

Exception name: CONSTRAINT_ERROR Message: debugger.adb:586 Call stack

If I rsh to Machine A, and then in the remsh from Machine A, it successfully
gets into Wildebeest (based upon GDB 4.17), and then hangs... (as I
mentioned in the past email - and nobody answered why):

gvd --debugger "remsh SERVER2 -l dr  /opt/langtools/bin/gdb" --log-level 4
--host SERVER1 "/user/danr/pric3"

Well, on server2, I see that the following is running:
/opt/langtools/bin/gdb -nw -q

Looking at the logfile, I see the following:
[1] -> "set prompt (gdb) \n"
[1] <- "(gdb) "
[1] -> "set width 0\n"

Why did this stop here?


Will it work well enough with Wildebeest 2 (which is based upon gdb, it even
has gdb prompts and the file is called gdb) 4.17 and runs when typing gdb?
How about 2.1 which is based upon gdb 5.x? (Or at least the subset of
commands which aren't new in 5.x?)

FYI, I don't need XDB compatibility, as we're migrating to a HPUX 11 machine
without it...
Thanks,
	Dan

Yes, through the preferences, as you correctly guessed in your mail.
However, I doubt you will be able to specify the password, I don't think we
correctly handle the question from external programs like rsh. You should
instead play with a .rhosts file, which is the standard way to avoid giving
passwords with rsh.

Anyway, try creating a $HOME/.gvd/preferences file that contains the
following:


<?xml version="1.0"?>
<GVD_Preferences>
  <Remote_Copy>rcp</Remote_Copy>
  <Remote_Protocol>rexec</Remote_Protocol>
</GVD_Preferences>
