Re: sftp and PASE on IBM i V6R1

Hi Karl,

I don't understand why you're responding off-list. Can we keep our
discussion on the mailing list please? Other people may be interested in
the outcome.

Yes, sftp is part of 5733SC1, option 1. (Assuming you didn't get a
different object also named 'sftp' using some other method?)

And, yes I'm assuming that pthread is part of PASE (5761SS1, option 33).

I hesitate to suggest what you might reinstall, I don't know what's
running/installed on your system and therefore I don't know what you might
impact. Maybe contact IBM for assistance? (I assume you have a support
contract for IBM i)

Hi,

I tried to include on the script /QOpenSys/usr/bin/sftp... but the same
error still occured.

You are right Scott, I have the same issue interactively.

We have other V6R1 machine and I tried the following.
I removed licence program 5733SC1 Base + Opt 1 and restore them from an
other V6R1 (via SAVLICPGM / RSTLICPGM)

I still have the same issue.


does sftp came from 5733SC1 opt 1 and pthread come from 5761SS1 opt 33 ?

What do you suggest? Should I reinstall licences program 5761SS1 opt33
and 5733SC1 Base + option 1 from IBM DVD ?

Thank you,
Karl

Hi Karl,

The message "Symbol __pthread (number 93) is not exported. . ."
means that the version of the pthread library on your system does
not match the one that sftp was compiled for.

(You should receive the same error if you run sftp interactively,
instead of running it via Expect.)

To try to put this in terms you might already understand: The
pthread library (/usr/lib/libpthreads.a) is very similar to what we
call a *SRVPGM in the ILE environment. The sftp program is trying
to call a "symbol" (=exported procedure) from that library (=service
program) but it doesn't have the same export number.

Since sftp is typically provided by IBM, you may have installed a
newer version of sftp that's not supported by the operating system
you installed it onto. (For example, maybe you installed a copy of
OpenSSH that requires V5R4, but you're trying to install it onto
V5R3) Or perhaps you are running on a current operating system, but
have an older version of PASE installed? (for example, maybe you're
running V5R3, but have the V5R2 version of PASE installed.) Those
are the sorts of things to look for.

Hope that helps.

Hi ,

We are using PASE environment to upload some files to an
external secure
ftp server over SSH.
Our server is V6R1

We are using the example from Scott with the expect tool.

The script is pretty simple and it does work fine on many other
IBM i
server.

We load variables with ADDENVVAR and call QP2TERM

Call QP2Shell Parm('/QOpenSys/bin/sh' '-c' &Parm3) ... and we
have the
following error. (I also try the command interactivly... same
error)



spawn sftp MyUser@ftp.destinationserver._**_com
<mailto:MyUser@ftp.**destinationserver.com<MyUser@xxxxxxxxxxxxxxxxxxxxxxxxx>

Could not load program sftp:
Symbol resolution failed for sftp because:
Symbol __pthread (number 93) is not exported from dependent
module /usr/lib/libpthreads.a(shr___**xpg5.o).

Examine .loader section symbols with the 'dump -Tv' command.



Licence programs 5733SC1 *Base and Option 1 are installed. (I
also try to
reinstall then, but I still have the same error)


5733SC1 *BASE IBM Portable Utilities for i5/OS
5733SC1 1 OpenSSH, OpenSSL, zlib

Does someone know what this error means?
I did some search on google but many unresolved post.

I know I little bit how Pase work, but I'm not familiar with.


Thanks for your help.

Karl
