I think you have to compile; find "rsh" in the [Mm]*k*files and change
it to "ssh".  sam will then run another sam on the remote system via
ssh when you type "sam -r remote-system".  You have to arrange things
so that the remote side has your public ssh key and you don't have a
passphrase protecting your ssh keys.

Russ had an authentication agent worked up for that case, right?

If I'm going to recompile sam, I may as well make that a command line
option, although I think Scott's suggestion of mounting ssh in rx's
place is excellent.

"s" is already taken as a sam command line option, it is tempting to
use a capital "R" instead of the lower case, but I think that may be
counter-intuitive in some fashion.

As for identity, I'm prepared to use ~/.shost (multiple heresy!) at
least initially, and Russ's "agent" may be what I need, although I
have trouble understanding that.

Further opinions/suggestions?

Sorry, I thought Lucio was talking about Unix sam.

I didn't specify.  I prefer the 3ed version, I have to confess, but
I just wanted to edit a remote file over a slow Internet link that
only allows me convenient access over SSH.   I have Unix, Plan 9 and
Windows versions of SAM, I don't mind which one I use.

I presume the above means that you second Scott's approach?

On unix, I recompiled sam to exec ssh, so I second Geoff's approach.  :)

[9fans] sam and ssh

[Lucio De Re]

Something in an early 3ed discussion gave me the impression that sam
can be run to a remote host over an ssh session.  I haven't quite
managed to get my mind around this, but I assume it means that sam can
originate an ssh session and request the remote ssh daemon to tunnel
the traffic.  Another possibility would be to use ssh tunneling, but
that's a pain at best.

Anyone would like to explain how it ought to be done, if I understood
the idea properly?  I seem to remember that the feature is available
in the Win version of sam too.  I can't find any details in the sam
man pages, but I'm notorious for not seeing the obvious :-(

Sam always runs as two processes, and "sam -r" uses rx to launch the
backend on a remote system.  To use ssh instead, bind /bin/ssh on top
of /bin/rx.

Only in the new Windows version from the Plan 9 updates
page.  Running sam -r some_host from a Windows 98 box works
great, but it fails on Win95 and I haven't been able to
get sam to work at all on XP.  I haven't tried WinME.

On Windows sam uses srx which will pop up a window for
you to enter a username/password for the ssh connection.
I don't understand the behaviour on Win95: if I run srx
from a DOS window, it works fine and I can run any command
on the remote host.  If I run it from within a 9term window
I get 'fatal error: could not dial: some_host: socket:
error 10106'.  I get the sam message from sam -r if I run
it from within 9term.  If I run sam -r in a DOS window,
it fails, but prints no message.

Tempting, but I won't install WinME just to check :-(  I'll keep it in
mind if I get near a WinME installation, additional motivation, as it
were...

Not on WinNT: I get a "panic: can't connect yet".

Where do you get 9term?!

Hm, I suppose one can consult the MS KB for that error number.  The IP
stack under Win isn't wonderful and the error messages are an absolute
treat :-(

Not even a very fast "not for console mode"?  Then again, I can't find
rsx either, I must be looking in totally the wrong place.

Yep, I was.  Nice new, unused tools :-)  Yum!

For the record, under NT, SAM doesn't seem to care to connect
remotely, much.

Seems like I need a Win refresher course :-(

Sam under NT exhibits the same behaviour as suggested for 98, it
doesn't prompt for authentication if spawned from a 9term.

Nice tools, definitely.  I'm glad I asked the question, now.

I'm an unreliable witl^Hness :-(

I'm going to shut up now.  Under NT, sam works both off a DOS
command line and 9term.  Seems to take a while to get going, that's
all, and the prompt window needs to rise to the surface, not stay
buried under all the other garbage.

[peter huang]

I was able to copy plink.exe (from putty) over srx.exe.   I was able to edit
files from unix environment (this is under win2k).  the srx.exe works but I
want have better control of my ssh environment (such ssh2 and public key
support with openssh).
