Re: SSHD terminates immediately with permission(?) problem

Can you change the port from 22 to something over 1023 for a quick test?

When I run that code (on Linux) and tell it to listen on port 12345 it 
works just fine.  When I specify something under 1024, it fails with the 
"Cannot bind..." message.


However if I specify a port less than 1024 and run it under root uid=0, 
it works fine.  In other words, in Linux (and I think the mainframe USS 
too) you're not allowed to listen on a port less than 1024 unless you're 
root.


But you already checked that the task is running under uid=0, so that's 
why I'm confused.  However, the message indicated "Bind" so I don't 
think it has anything to do with certificates.  I'm pretty sure any TLS 
and cert negotiation comes after the bind() in a server program.

Re: SSHD terminates immediately with permission(?) problem

[Michael Babcock]

Check your TCPIP config member.   Something else is listening on port 22.
Perhaps another SSHD.   Issue the netstat command to see the offender.

Re: FTP client question

[Joel C. Ewing]

I suspect "connection" in this context means the opening of a TCP/IP 
socket, which establishes the path between ports on two nodes, and that 
all subsequent packets follow that established path.  That would  
suggest that transmission of a single file by one FTP instance would 
still be constrained to the bandwidth of a single interface.  My 
understanding of load balancing is that it distributes aggregate load 
over multiple interfaces by spreading multiple transactions over 
multiple paths rather than spreading multiple packets for the same 
transaction over multiple paths--so alternate routes for packets of a 
single FTP transaction wouldn't be an issue.


If your object is to make two 1 Gbps interfaces behave as one 2-Gbps 
interface for a single transaction, I believe that would be closer to 
what is called Ethernet bonding of interfaces.  I know Linux can support 
this if you also have an Ethernet switch that can support bonding (and 
that can support aggregate rates of 2Gbps).  I don't know if that is 
supported on z/OS.  My understanding is that this can allow packets 
associated with the same TCP/IP socket to follow different physical 
paths, but the unit of transmission is still a packet.  FTP transmitting 
a large file supports multiple packets in flight before having to 
receive a response back so it should be able to effectively utilize the 
aggregate bandwidth by spreading those packets over multiple 
interfaces.  If FTP is in an interaction where a single packet is sent 
and a response packet must be received before proceeding, you would 
still be constrained by the bandwidth of a single interface because each 
individual packet still travels over one physical interface.

You could use either default, or code routes for specific

coding more specific routes will just load blance the traffic for 
hosts matching those routes.


You then add add one of the following statements to your IPCONFIG

First one will have z/OS alternate which route it takes per TCP

path/route #2.  Depending on timing all 3 jobs could still get sent 
out the same OSA, but you will be using both OSA's so it won't impact 
all traffic.


Second one does the same thing, but per packet.  More overhead but 
both OSA's will be used "equally".


No matter what you do, depending on your network setup either one of 
these or, as Keith suggested, defining a ROUTE via a specific 
Interface you could overload your network. If your whole 
infrastructure is 1 Gbps Ethernet, your z/OS system can now push ~2 
Gbps through the network.

Networking is not my speciality but you should be able to add a HOST

Something like this:


ROUTE windows server IP address.  HOST   =   OSA_INTERFACE2

where OSA_INTERFACE2 is the interface which you want to use.

This example assumes that the server is on the same subnet as the

Re: [EXTERNAL] Re: zOSMF

[Shaffer, Terri]

While I see where you went with your thought process, the mainframe I don’t 
think will ever get to a windows or Android mentality.

I mean I know IBM wants to make the mainframe less complex, but by design that 
can only go so far.

For example, How many SMPE environments does a company have? How many Catalogs> 
How are the volumes laid out?  RES, DLIB, CATALOG, Paging, ETC...

Can you sort of automate the day to day management, or operations, yes.  Or how 
about how is maintenance applied, If I use your examples of windows/Android. 
Its live update, not sure that would fly in any company.  And whats my backout 
if something doesn’t work? Think of what you said, your reset your phone and 
started again.. H

z/OSMF is the IBM forced method here, and they have taken a process that has 
worked for 25+ years,  like I want to copy the old config settings from a 
previous z/OS install.  Why should I have to re-invent that wheel every time I 
install z/OS?  I use to be able to do a serverpac in a few hours, now with the 
z/OSMF response time and issues, that isn’t possible.

I still like the option that was mentioned, 2 switches, Novice, which forces 
you do everything and advanced, which would allow me to bypass steps or under 
the cover processes, IBM is forcing!!  Its just like windows, when I select 
advanced install option.

In a way I am glad I have only 7 more years left until retirement.  I love the 
mainframe and z/OS, but I avoid z/OSMF like the plague, I will only use it for 
z/OS installs only because I am forced too..

That’s the *goal*. Do you know what the Windows installer is doing? Android? 
iOS? No you do not, beyond the high-level “putting  in places” and “making 
it bootable”. While it makes me nervous because, like you, I’ve been doing this 
for too long, most people see this as a good thing, and I can’t really dispute 
it.

In 1920, if you had a car, you understood air/fuel mixture, how to do oil and 
tire changes, etc. Most people don’t now, and that’s not a bad thing. Sure, 
occasionally they get stranded, but by and large, it Just Works.

On the flip side, I was switching phones and the migration failed. I did a 
reset of the new phone and restarted it, and it worked the second time. Did I 
understand the process? No. Did I need to? No. Am I happy that I couldn’t tell 
what failed? Not really, but, again, I really didn’t need to. And 99.44% of 
people wouldn’t care, as long as it worked the second try.

and Colin Paice asked:
>Would it help if we moved to standard configurations?

That’s the point I made before: with Windows, you’re forced into a fairly 
standard configuration. With z/OS, it’s a bit late (by almost six decades): 
sites aren’t going to rearrange everything. For new installs (all handful of 
them), sure. But that doesn’t really help at this point, alas.

Re: Effective region

A long time ago when I was working on a limit exit, for testing I would 
run a small program that did a variable length getmain for below/above 
the line, something like this:


  GETMAIN VRC,LV=(1600,32)
  GETMAIN VRC,LV=(20,32),LOC=ANY

... and then spit out the results.  The idea was to avoid using any of 
the storage control blocks and see what *really* came back.  Maybe 
there's something on the CBT Tape that would do similar.

That’s the *goal*. Do you know what the Windows installer is doing? Android? 
iOS? No you do not, beyond the high-level “putting  in places” and “making 
it bootable”. While it makes me nervous because, like you, I’ve been doing this 
for too long, most people see this as a good thing, and I can’t really dispute 
it.

In 1920, if you had a car, you understood air/fuel mixture, how to do oil and 
tire changes, etc. Most people don’t now, and that’s not a bad thing. Sure, 
occasionally they get stranded, but by and large, it Just Works.

On the flip side, I was switching phones and the migration failed. I did a 
reset of the new phone and restarted it, and it worked the second time. Did I 
understand the process? No. Did I need to? No. Am I happy that I couldn’t tell 
what failed? Not really, but, again, I really didn’t need to. And 99.44% of 
people wouldn’t care, as long as it worked the second try.

and Colin Paice asked:
>Would it help if we moved to standard configurations?

That’s the point I made before: with Windows, you’re forced into a fairly 
standard configuration. With z/OS, it’s a bit late (by almost six decades): 
sites aren’t going to rearrange everything. For new installs (all handful of 
them), sure. But that doesn’t really help at this point, alas.

FSF and Linux can reasonably be ignored in this discussion but was there a time 
when Unix System Services (of z/OS or OS/390) was competitor to other platforms 
that claimed to be UNIX? How many third party apps were available / supported / 
marketed for USS as against AIX, HPUX or Solaris? How many of those were 
actually being run on USS? Certificate is fine on the wall but what actually 
does the job is more important.

Re: FTP client question

I have a question about the alternating of packets.

If one is using an MFT product with encryption and hand-shakes, 
will the alternating packets between routes not cause the 
"connection" and data xfer(s) to fail?


I'm asking because I know just enough about Network traffic to be 
truly dangerous -- which means I know how to specify an IP 
address and port#, and not much more.

No, because I'm assembler (almost) illiterate. No, because as far as I

However I reviewed SMF30 data and I think this is the direction I should
follow. That means some report I have to create.

In the past I have complained about non-conformance and been told

Will it finally support the -P and -L options of cd and pwd, with the default

Thank you for this posting. It brings up a question that I've had 
since a problem with getting z/OS 1.6 installed...


Back when I did do z/OS sys-programming, you had to have a 
driving system (at a specific level or above) to install z/OS


So we are the ABCZ company and we have decided to get a new z16 
and setup a z/OS environment. Now how do we install this since we 
have never had a z/OS system before?


This is the thing that troubles me when we are being told about 
new installations. Maybe a VM system running Linux for z, or 
equivalent. But to get z/OS installed for the first time? How do 
you do that?

The point that I am trying to make is that you may be able to do a z/OS

So, I suppose that the next step will be some kind of IA doing the install

I’m going to take that as a straight question. I assume the question was,
“How do we make z/OS easier to install and maintain for folks who don’t
have any grey hair yet?”

This is essentially the same question that led to GUIs in general. The
problem is that it’s not trivial to answer—putting some lipstick on the

pig

doesn’t always do it: sometimes you need to restructure the pig.



I’m reminded of the Windows version of the Relay/Gold terminal emulator,
which was acquired by VM Systems Group when I was there. Under certain

SDLC

error conditions, it would drop out of the Windows UI into a DOS error
dialog. Which was not really recoverable, since it needed someone to

press

a key. At one point a customer was considering buying a power strip that
plugged into a phone line and could be called to cause it to power cycle,
as they had an automated process that would be stopped when this error
occurred. Talk about a Rube Goldberg solution! I’m sure the real fix was

a

single line of code somewhere, but finding that was non-trivial, of

course.

Especially since Relay/Gold was written in x86 assembler, a non-standard
variant from a dead company. So there were no diagnostic tools to speak

of.

And as a tiny vendor, we didn’t have the hardware to even simulate the
error…Good times. /s

The only use I have found in many years for having z/OS UNIX certified is
so that when someone says they hear that z/OS has a "UNIX emulator" or any
one of many similar bogus claims, I can say "No, z/OS *is* UNIX. And BTW

Not to defend Timothy or z/OS :-)   however z/OS 3.1 is still before GA. 
So it will be Unix certified since day of premiere. That's good IMHO.

Billy,

The chapter 35(Writing object-oriented programs) in the application programming 
guide is a good place to start.

https://www.ibm.com/docs/en/cobol-zos/6.4?topic=programs-writing-object-oriented

And here is an example program.

Thanks,
Kolusu

Not tryna be contentious, just honestly confused: "already"? As opposed to 
what? I.e., what makes this an "already"?

Are there samples of COBOL methods or classes?

[Billy Ashton]

Hi, While working on the earlier problems I had, I ran into the concepts 
of COBOL Methods and Classes, and understand they can be used for Java 
in addition to regular COBOL programs. The documentation does not 
explain the "why" behind these or the "how" and "what", so I wonder if 
anyone has any business case explanations of what these are or samples 
of some COBOL-only implementations so I can see why I might want to use 
them and how to do it?


I like to keep my COBOL current and if there is a way to use COBOL more 
effectively, I hope you can help me understand this!


Thank you and best regards,
Billy Ashton

Re: zOSMF

Would it help if we moved to standard configurations?

With ADCD environment you unzip files to get the 3390 images. You get
working system out if the box, and SMP/e environment. This looks like a
good way to go and may fit many people's requirements.   This takes away a
lot of the complexity, and allows you to start from a working base.

Re: zOSMF

[Jack Zukt]

The real problem, as I see it, is that drag and drop interfaces move you
away from the need to know what you are doing. A long time ago, the first
MVS install that I did on my own, took me a few months to do it. I was
doing it under VM/XA and I did a few complete back to square one at the
time, as I was not pressed for time. At the time I had about two years of
MVS experience. I did read a lot of MVS and JES2 reading, you know,
installation guides,  references, customization and such. When I finnaly
was satisfied with the system I knew a lot more than when I started.
The point that I am trying to make is that you may be able to do a z/OS
install using zosmf knowing next to nothing of z/OS, but with that
knowledge you will not be able to debug any kind of problem that you will
get in your way.
So, I suppose that the next step will be some kind of IA doing the install
and problem solving.
That makes me glad that I am not so far away from retirement.
