nettle-users Mailing List for Nettle

Hi All,


I have got !nettle to open on boot but is closed and to the bottom right corner.

I would like it to boot to the !nettle window how do i do this?

Also I would like to setup !nettle function keys... is this possible?
Regards,

Thanks!

Here's the latest patch for SSH support using libssh2. It is now
conditional and only compiled in if WITH_SSH is defined.

There, committed now. I didn't test the GCC build bit of it, I'll just 
assume it works :)

Alex.

As suggested in the discussion in June, I've separated the changes for
gccsdk from the changes for ssh using libssh2.

Here are the changes for cross-compiling with recent gccsdk, including a
new makefile (called GNUmakefile so that it doesn't conflict with the
current one).

If you'd like me to commit it, my sf username is bursa.

Yeah, it all seemed to build OK, I just need to sort out the missing 
library symbol issues. Will maybe get some time this weekend.

I'd probably suggest ifdeffing your changes so we can still build 
without SSH - 1. because Norcroft builds of it won't work just yet, 2. I 
seem to recall PuTTY does something similar because of issues with using 
SSH in certain countries, so can ship both an SSH and non-SSH version.

May also be worthwhile thinking about committing a separate Makefile 
etc. for building with gcc? (if that's feasible)

Cheers,

Alex.

Hi Alex,

Thanks for looking at it. Do you mean that you got libssh2 compiling, but not 
a fully linked Nettle yet?

Are there any changes I should make before this can be checked in?

Yeah, I did start working on getting libssh2 working with Norcroft, but 
got sidetracked :) It all builds now IIRC, but there were some Unixy 
symbols that weren't in the Norcroft unixlib etc. libraries, and I 
haven't yet got around to 'fixing' those.

Alex.

I have started implementing SSH support in Nettle using libssh2, 
http://www.libssh2.org/

The basics are working in my tests connecting to two Linux hosts. Please see 
the attached patch.

A build of this is at http://zamez.org/nettlejcb.zip

It's built using gccsdk. Some minor changes that aren't in the patch were 
required to make it compile with gcc.

James

This version is essentially the same as the last released version 
(0.2042r), but should hopefully be compiled to run correctly on the 
BeagleBoard, and also includes the newer ZapRedraw module which should 
also work (although Dave Higton reports it doesn't work standalone for 
some reason, and requires a proper !ZapFonts install).

Feel free to give it a try and let me know of any problems.

Cheers,

Alex.

Yeah, I had that problem once.  Some ssh binaries are better than others.
Try this one:

  http://www.smoothartist.com/temp/ssh.zip

I got it from John Tytgat and it seems to work much better.

I'm not sure what the cause is.

Anyway, it would be much better to have SSH support properly integrated
into Nettle.

Are any of Nettle's original developers still around?

Ah, I guess that explains it. :)

ssh exiting when I hit an arrow key is a bit of a pain. I assumed this 
is due to TaskWindow seeing a '27' input byte and causing an escape 
condition. Might be worth having a look at TaskWindow now its source 
is available.

Perhaps. Would be possible to get UTF-8 input on RISC OS 5 working as 
well. Is there any way for Nettle to determine the character set of a 
terminal automatically?

I noticed that LINES, ROWS and COLUMNS system variables are set by 
Nettle, presumably to communicate the size of the terminal to UNIX 
ports. Obviously these are global which could produce the weirdness 
you see.

Yes, me too.  I use an ssh binary as an ANSI task in Nettle, which works
up to a point.

I nearly always have Nettle running ssh connected to a Linux computer
running irssi, for IRC.  The main problem I have is when someone says
something that uses a Unicode character, the display in Nettle gets
mangled.  ZapRedraw can do Unicode characters now, but maybe Nettle needs
to be updated to use it properly?

Also, I find that if I have two Nettle windows (running the ssh ANSI task,
although I'm not sure that matters), then they both need to have the same
width and height.  If I make one window have a greater height, for
example, the other window starts displaying its content wrongly.

Best regards,

They look fine from a brief nosy - not sure I'll have time to do 
anything with them in the next week, but hopefully will have time next 
weekend :)

Diffs to everything other than the template files here:

Yes I know. I wasn't formally submitting anything, I was more trying
to gauge interest. The changes themselves are fairly minimal, and
there are still things to do.

I'll do a diff over the next few days, time allowing.

I'm sure block drivers could be made to work and I guess would be
better for some people with dual serial cards etc., though personally
I'd prefer to use DeviceFS. I think it is a more flexible interface,
and as part of the OS is, perhaps, more future proof.

Also what I've done can be used to talk and/or listen to any suitable
DeviceFS device as long as it can open at least one of the Tx or Rx
streams.

SSH is something I'm interested in as I use it a lot and there is no
comprehensive solution for RISC OS at present. Not sure whether I
would have time to do this.

source - harder to see what changes have been made :)

Not sure about using DeviceFS - wonder whether it might be better to use 
the serial blockdrivers instead, although not sure how well they fit 
into a C application.

SSH never really got going - I created an SSH module based on PuTTY a 
few years back, and put some random hooks into Nettle to use that, but 
PuTTY wasn't well suited to running as a module really (it did work to 
an extent though).

Someone suggested using http://www.libssh.org/ instead, but I never got 
up the motivation to actually try integrating it.

Alex.

Is anyone here?

I've made a small addition to !Nettle, adding support for talking to
DeviceFS devices (e.g. serial ports). The changes are of prototype
quality and not very user friendly to those not familiar with
fileswitch special fields... But might be useful.

  http://effarig.co.uk/riscos/download/nettle.zip

Is there anyone still maintaining Nettle? If so would something as
prototyped above be a suitable addition? I also have a few questions
regarding how newlines are meant to work and what the plans were for
the beginnings of SSH support in the code.
