Hi gurus

I am trying to write a script that launches ssh sessions using
password authentication (i.e. I do not want to exchange keys). It
appears that the only way to do this is using Net::SSH::Perl. Is this
correct?

If so, then I am having difficulty installing it because one of the
prerequisites Math::Pari will not build on my Intel Solaris 9
machine. The first suspicious output appears when I run MakeFile.PL
and it downloads the PARI libraries:

Patching...
cd pari-2.1.7 ; patch -p1 < ../patches/patch-pari-unnormalized-float
Looks like a unified context diff.
done
cd pari-2.1.7 ; patch -p1 < ../patches/diff_2.1.7_-O
Looks like a unified context diff.
I can't seem to find a patch in there anywhere.
cd pari-2.1.7 ; patch -p1 < ../patches/diff_2.1.7_restart
Looks like a unified context diff.
The next patch looks like a unified context diff.
I can't seem to find a patch in there anywhere.
Finished patching...

Then, when I run make, it dies after:

/opt/SUNWspro/bin/cc -c -I .././pari-2.1.7/src -I.././pari-2.1.7/src/
headers -I.././pari-2.1.7/src/graph -I. -I/usr/local/include -

Current working directory /.cpan/build/Math-Pari-2.010709/libPARI
*** Error code 1
make: Fatal error: Command failed for target `libPARI/libPARI.a'

This happens also, when I force it to use the pari-2.3.2 libraries and
also when I do 'perl MakeFile.PL machine=none'. Unfortunately, I do
not know C - the offending lines are:

441: /* Given coordinates of ends of a line, and labels l1 l2 attached
to the
442: ends, plot ticks where the label coordinate takes "round"
values */
443:
444: static void
445: rectticks(PARI_plot *WW, long ne,
446: double dx1, double dy1, double dx2, double dy2,
447: double l1, double l2, long flags)
448: {
449: long dx,dy,dxy,dxy1,x1,y1,x2,y2,nticks,n,n1,d
n;
450: double minstep, maxstep, step, l_min, l_max, minl, maxl, dl,
dtx, dty, x, y;
451: double ddx, ddy;
452: static double mult[3] = { 2./1., 5./2., 10./5. };

If anybody has any ideas, I would be very grateful.

thanks

jon

This might not be what you're looking for but you could
backquotes(``), system or exec to launch a pre-installed SSH client.
Sorry if this does help.

I've worked around the problem by only using SSH protocol 1. This
only requires the Math::GMP module; not the Math::Pari module. If
anyone does have Math::Pari working though, I would be grateful to
know.

Many thanks

Jon
