Is there an ssh lisp library ? The only reason i'm using python
scripts for some of my tasks is because there's an ssh python library
that allows me to connect to remote sftp servers and upload some
files.

(with-open-stream (stream
#+clisp (ext:run-program "ssh"
:arguments (list (format nil ···@~A" "pjb" "localhost")
"bash"
"-c"
(format nil "\"cat > ~S\"" "test"))
:input :stream :output :terminal))
(princ "Hello world!" stream)
(terpri stream)
(finish-output stream))
Something similar can be done in most implementations.

for sftp it's even easier -- just call scp program, it uploads files just
fine

You can't be serious. What about error handling ? reading remote
folders ?
I do not wanna parse terminal output. Better stay with python.
But thanks for the answer. I got information i was looking for. There
are no lisp ssh libraries.

Hi
This is not really true.
All implementations have a kind of foreign language interface that can be used
to connect to i.e. openssl libs as in most other languages too. So all you need
to do is to write the FLI binding (or google for one). Thats btw. is the
same way Python (and various other languages) provide ssl.
However, it is possible that there is no native lisp implementation of ssl. But i
assume thats only because no one find any advantage in that. Ever thought about
(complete) verification of such a beast?
And as far as i know there are no native implementations in Perl/Python/Ruby.
Have you any good reason for a native implementation? I'm sure cll readers will happily support
your work if you decide to make one.
Finally, if you don't want to implement ssl by yourself and even don't want to create FLI
bindings, you are free to use a comercial Lisp. LispWorks for example comes with build-in
ssh support (and a lot of other goodies). I'm sure other comercial Lisps provide similar tools.

I think you're confusing SSL and SSH here. LispWorks has built-in SSL
support (which is nevertheless based on the C libs) and there are
portable open-source bindings like David Lichteblau's CL+SSL. But
AFAIK the OP is right that there are no Lisp libraries which support
SSH.

Hi Edi
Yes you are right (i never needed to use ssh/ssl from LispWorks so i remember
not exactly).
However, it should not be harder to implement in Lisp (using FLI bindings to
openssl) than in any other language.

Still no; there's libssl but no libssh on most systems... SSL was
designed for library use; SSH was not. OpenSSH (and presumably
others) rabidly avoid linking against untrusted code.
The Python SSH the OP mentioned is actually an entire SSH stack
written on top of the Twisted library. Whether its as secure as the
others is debatable, but it is usable.
Python also had some expect-style shell interaction libraries (e.g.
PySSH); but I don't think these are actively developed since the
Twisted library became available.

Yes very serrious.

You could implement all that, or port tramp from emacs lisp to Common Lisp.

I don't see how you would avoid it with a lisp function. What would
(ssh :login "user" :host "remote" :command "ls" :arguments '("-l"))
return?

Is there a C ssh library? If there is one, then there is a lisp
one. Just use CFFI to call functions in the C ssh library.

Couldn't find anything useable when i looked last time. Curl but this
is total
crap, almost as less control as calling "ssh" or "scp". Useless for
anything other then HTTP.

there is. tramp. last time i've checked emacs lisp is lisp.

I should have been more specific: sbcl
To those who says "use FFI":
Yes I know that to every question about any possible feature or
library you can always answer FFI. But unless you have a ready
bindings, that answer is useless. I did know about FFI without your
help.
I'm looking for readily available solution. Does not matter in which
form, native library or FFI bindings. If there's no such thing just
say it. I'll figure out FFI part myself.

I mentionned CFFI. You don't need ready bindings, CFFI elaborates its
bindings automatically from the header files. Unless the C headers are
pathologic, this should give you an usable entry point.

Thanks, i did not know it. I'll check cffi documentation.

No SSH/SFTP library proper, but cl-curl may be usable if you're just
uploading files over sftp. Newer curl libraries are SFTP-compatible,
I believe using libssh2.
