netcat (nc) on AIX does not exist. If you want to install it, it requires a million other packages as requisites that do not exist on AIX either - it is strictly speaking painful.
Without it, you will not be able to force AIX to use a specific source IP adress as AIX will always decide by itself which source IP to use consulting the routing table.
The easiest way to test - if you can have a temporary downtime for testing - is to temporarily change your IP address to the alias IP address and then simply telnet destinationhost port ? - And once tested just change it back.
In reality - considering that your alias sits o a physical adapter with an underlying IP, why do you even care?

NAME
README.os400 - Perl version 5 on OS/400
DESCRIPTION
This document describes various features of IBM's OS/400 operating system that will affect how Perl version 5 (hereafter just Perl) is com-
piled and/or runs.
By far the easiest way to build Perl for OS/400 is to use the PASE (Portable Application Solutions Environment), for more information see
http://www.iseries.ibm.com/developer/factory/pase/index.html This environment allows one to use AIX APIs while programming, and it provides
a runtime that allows AIX binaries to execute directly on the PowerPC iSeries.
Compiling Perl for OS/400 PASE
The recommended way to build Perl for the OS/400 PASE is to build the Perl 5 source code (release 5.8.1 or later) under AIX.
The trick is to give a special parameter to the Configure shell script when running it on AIX:
sh Configure -DPASE ...
The default installation directory of Perl under PASE is /QOpenSys/perl. This can be modified if needed with Configure parameter -Dpre-
fix=/some/dir.
Starting from OS/400 V5R2 the IBM Visual Age compiler is supported on OS/400 PASE, so it is possible to build Perl natively on OS/400. The
easier way, however, is to compile in AIX, as just described.
If building natively on PASE, please do the build under the /QOpenSys directory, since Perl is happier when built on a case sensitive
filesystem.
Installing Perl in OS/400 PASE
If you are compiling on AIX, simply do a "make install" on the AIX box. Once the install finishes, tar up the /QOpenSys/perl directory.
Transfer the tarball to the OS/400 using FTP with the following commands:
> binary
> site namefmt 1
> put perl.tar /QOpenSys
Once you have it on, simply bring up a PASE shell and extract the tarball.
If you are compiling in PASE, then "make install" is the only thing you will need to do.
The default path for perl binary is /QOpenSys/perl/bin/perl. You'll want to symlink /QOpenSys/usr/bin/perl to this file so you don't have
to modify your path.
Using Perl in OS/400 PASE
Perl in PASE may be used in the same manner as you would use Perl on AIX.
Scripts starting with #!/usr/bin/perl should work if you have /QOpenSys/usr/bin/perl symlinked to your perl binary. This will not work if
you've done a setuid/setgid or have environment variable PASE_EXEC_QOPENSYS="N". If you have V5R1, you'll need to get the latest PTFs to
have this feature. Scripts starting with #!/QOpenSys/perl/bin/perl should always work.
Known Problems
When compiling in PASE, there is no "oslevel" command. Therefore, you may want to create a script called "oslevel" that echoes the level
of AIX that your version of PASE runtime supports. If you're unsure, consult your documentation or use "4.3.3.0".
If you have test cases that fail, check for the existence of spool files. The test case may be trying to use a syscall that is not imple-
mented in PASE. To avoid the SIGILL, try setting the PASE_SYSCALL_NOSIGILL environment variable or have a handler for the SIGILL. If you
can compile programs for PASE, run the config script and edit config.sh when it gives you the option. If you want to remove fchdir(),
which isn't implement in V5R1, simply change the line that says:
d_fchdir='define'
to
d_fchdir='undef'
and then compile Perl. The places where fchdir() is used have alternatives for systems that do not have fchdir() available.
Perl on ILE
There exists a port of Perl to the ILE environment. This port, however, is based quite an old release of Perl, Perl 5.00502 (August 1998).
(As of July 2002 the latest release of Perl is 5.8.0, and even 5.6.1 has been out since April 2001.) If you need to run Perl on ILE,
though, you may need this older port: http://www.cpan.org/ports/#os400 Note that any Perl release later than 5.00502 has not been ported to
ILE.
If you need to use Perl in the ILE environment, you may want to consider using Qp2RunPase() to call the PASE version of Perl.
