SSH in AIX 4.3+

[C C]

How do I startup SSH in my RS6000 with AIX 4.3?

Thanks in advance.

If you can find an old copy of the "toolbox for Linux" CD which comes with
AIX nowadays, one with the "RPMS/ppc-4.3.3" subdirectory, as shipped with
the original AIX 5.1, you can install it from that. I wouldn't expose one
that old to the Internet though. It used to be available for download but
I think they removed all the 4.3.3 stuff.

You can get a version from http://www.bullfreeware.com/. There are more
recent ones there.

Or get the source from http://www.openssh.org/portable.html and build it
yourself. I recommend this if it's exposed to the Internet.

Thanks. Is this pretty easy to install? Does it need a reboot?

Installing one of the binary distributions is easy enough. If you install
the IBM RPM you have to install RPM itself first, which is provided on the
same CD as a BFF, under "INSTALLP". And openssl and, I think, prngd which
are also on the same CD, as RPMs. The Bull one should be perfectly
straightforward. I expect it'll depend on openssl too, but that's on the
same site. If you can't find a copy of the toolbox CD of the right vintage
that'll be the easiest.

Compiling from source is a bit of a grind, you'll have to read the
instructions carefully and compile the pre-reqs first. I'd recommend one
of the easier paths unless it's being used on the Internet.

No reboot is needed in any case. You may have to start the sshd daemon. If
you use the IBM RPM it creates a subsystem and, IIRC starts it but if it
doesn't you just have to startsrc it. It puts it into system startup,
using the SysV run level heirarchy, in /etc/rc.d/rc2.d, it's the only
thing I've ever seen land there by default. I don't know what the Bull
offering does. If you build from source you'll have to start it yourself
and also arrange for it to get restarted at boot.

Darren Tucker, one of the OpenSSH developers, also has up-to-date,
pre-compiled, ready-to-roll binaries for AIX 4.2.1+ in BFF format on his
personal site:

http://dtucker.freeshell.org/openssh/

These binaries have all the dependencies statically compiled so there is
no drama matching libraries etc. They install in /usr/local, so you
need to take care if using them to update the IBM versions which are
just in /usr.

On AIX 5.2 installing the BFF with SMIT added the startup of sshd to
/etc/rc.tcpip - I can't vouch for the same thing on AIX 4.x as I don't
have any systems using this version.

HTH,
Andy.
