Hi,

The pure-ftpd package that comes with SLES9 supports FTP over SSL/TLS 
(http://www.pureftpd.org/project/pure-ftpd).

Subject: Re: FTPS (FTP over SSL) Package for SLES9

Does anyone know of a FTPS (FTP over SSL) client package that will work
on SLES9 on the S390?  I need to send a file to a remote server who
requires ftp over ssl.  I made a mistake and assumed that sftp was the
same thing.  I understand vsftpd supports ftp over ssl but I don't see
how to setup a client to initiate the data transfer process.  Also, I
read in one of the threads sftp (using ssh) could also be configured to
support ssl.  I have not found any documentation the shows how to
configure that either.  Any help would be very much appreciated.

Opps, sorry, I didn't notice that what Douglas needs is an FTP SSL client.
 
Based on that I think that the ckermit package that comes with SLES9 will help 
you. We currently use the package to automatically download files from a 
FTP/SSL site. It provides lots of scripting capabilities... if you need some 
scripts examples just let me know...

True, but that doesn't provide a _client_ which is what Douglas is
after.

I got some replies from my internal queries.  Amazingly (to me), SLES
doesn't have an FTP client that supports FTPS.  OpenSUSE does, but not
SLES.  :(

I'm going to be putting an internal RFE to have that added, or have
lukemftp rebuilt to support it (assuming the code is there).

Hi Mark,

 

This simple ckermit script receives several values as parameters (ip, port, 
user, etc.), it basically uploads the contents of a local directory, it will 
use TLS:

 

#!/usr/bin/kermit +

 

  SET FTP VERBOSE-MODE ON

  SET FTP AUTHTYPE TLS

  SET AUTH TLS CERTS-OK

  SET FTP AUTOAUTHENTICATION OFF

 

  SET TRANSACTION-LOG BRIEF

  LOG TRANSACTIONS /var/kermit_ftp.log APPEND

 

  .ip := \fcontents(\%1)

  .port   := \fcontents(\%2)

  .user   := \fcontents(\%3)

  .password   := \fcontents(\%4)

  .ldirectory := \fcontents(\%5)

  .rdirectory := \fcontents(\%6)

 

  ftp open \%1 \%2 /user:\%3 /password:\%4

  if fail exit 1 \%1: Connection failed

  if not \v(ftp_loggedin) exit 1 Login failed

 

  lcd \m(ldirectory)

  if fail exit 1 lcd: \v(errstring)

 

  ftp cd \m(rdirectory)   ; CD to desired server directory

I don't know if Douglas needs some script samples, but I would like to

see a few small ones, particularly how the SSL/TLS aspect gets invoked

within an FTP session.

I was unsuccessful in getting this script to work.  However, that could have 
been because all ftp traffic from my Linux system's IP Address was blocked at

Actually, for users across multiple systems, I think LDAP is your friend.
You can restrict users to specific Linux guests, a single password change
effects the user across all the systems, it enforces the uid being the same
across all the systems (important if you use nfs or ftp...) and you have a
single point for account maintenance.

There's some effort in setting it up, but in the end, it will save you
considerable time.

Hi,
from a Linux SLES9X  using  "ftp client" and   i.e.   " mget  *.txt "

My scope is to download  only  the newer  or  not  present  on local site

I need to run ftp download manually and  I cannot use  rsync.

An  useful  tool like FILEZILLA  could be used using VNC session but  I

Reading  man ftp   SLES9X  we can find :

runique Toggle storing of files on the local system with unique file­
names.  If a file already exists with a name equal to
the
target local filename for a get or mget command, a ".1"

Than FTP setting   "runique"   it rename  the file with a numeric extention

We ran into this (and a couple of other things).  We fixed it by putting 
SBDATACON (IBM-1047,ISO8859-1) in SYS1.TCPPARMS(FTPDATA).  Your dataset name 
might be different.  It can be specified in the start proc.

I think you can specify SBDATACON in a site command, so you could test and see 
if it fixes your problem.  I don't remember the exact syntax, however a site

Hi List,
I am trying to ftp a plain txt file to zOS.
If I use the WARP option, the whole file is transfered as one continusous
string.
If I don't use the WARP option, the file is transfered as a continuous
string but it also gets truncated ( determined by blksize ).
Either way, it looks like ftp is not handling the linux LF properly.  It
ends up as a x'25' on the zOS platform.

Has anyone encountered this before ?

No. 

z/OS cannot read Linux DASD if the DASD is "Open Systems" connected.
However, if it is ECKD, then z/OS could theoritically read it. However,
you'd need to implement the filesystem driver code on z/OS. This could
be "user space" code that actually does EXCP processing (or XDAP) or one
of the more advanced I/O methods. Come to think of it, BDAM might even
work. But remember that if the filesystem is read-write to some Linux
system at the time, the DASD may be "fuzzy" and not contain the actual
data as would be seen by a Linux program. This is due to the aggressive
caching done by Linux. Forget any read-write sharing. There be dragons
there. And blown filesystems, too.

There is a driver that runs on Linux which can read z/OS legacy
datasets, but not z/OS UNIX files. Interpreting the data is your
problem, not the I/O driver's! But I don't remember much about it. I
think that it is READ-ONLY.

Personal opinion time, doning Security Admin hat: There is NO way that I
would allow a Linux system to directly access my z/OS datasets. Why? No
ability to audit. No ability to restrict access and prove that access
was restricted to authorized users (thinking of HIPAA data).

Now, I __might__ consider it if only a very few z/OS volumes were even
accessable from the Linux system and I could assure myself that the
datasets on those volumes never contained any confidential information
that might require auditing.

Subject: FTPS with SSL/TLS and Clear Command Channel

Gidday,



We're looking to implement FTPS with certificates and SSL/TLS. We've tried
z/OS but it would appear that the server refuses to process Clear Command
Channel commands. So now we're looking for alternatives such as under z/VM
or z/Linux.

It seems that many FTPS servers under Linux are RFC 4217 compliant.

RFC 4217 (at http://tools.ietf.org/html/rfc4217#page-25) states...

15.3.  Issues with the CCC Command


   Using the CCC command can create security issues.  For a full
   description, see the "CLEAR COMMAND CHANNEL (CCC)" section of
   [RFC-2228].  Clients should not assume that a server will allow the
   CCC command to be processed.

   Server implementations may wish to refuse to process the CCC command
   on a session that has not passed through some form of client
   authentication (e.g., TLS client auth or FTP USER/PASS).  This can
   prevent anonymous clients from repeatedly requesting AUTH TLS
   followed by CCC to tie up resources on the server.

Can anyone advise whether there are packages available for z/Linux that
will allow CCC to be used, eg vsftpd?  We are SUSE SLES 10.1, if that
matters.

Re: New to zLinux... Backup solutions...

[José L . Ramírez]

What backup software you use for zOS backups? What we are currently doing is 
running weekly backups of Linux DASD from zOS using FDR. This works fine but 
you don't have the capability of doing file level restores, just the whole DASD.

Recently we defined a new virtual guest that is acting as an Amanda Master 
Server, Amanda is an Open Source backup utility which is part of basically all 
major distributions and is very well documented. After you have configured the 
server you just install the Amanda client on each guest you want to backup.

Subject: New to zLinux... Backup solutions...

We have installed a single zLinux VM on our s390 here.

I want to take a backup of this system in case something drastic happens (ie 
the developers/testers break it).

The zOS sys admin has informed me he has taken a copy of the system. However as 
he is also new to zVM, he is unsure of the restore process.

Normally for our linux/UNIX servers we use backup applications, or in some 
cases use dd.

What is the suggested solution for the actual zLinux OS. Is there anything we 
should be wary about? Does it have to be restored to the same disks etc.

Any help or pointers would be great.

Thanks

Re: NFS on the Mainframe

Hi Sipho,

Not sure what you are trying to accomplish, but assuming you want to run an NFS 
server under zOS and access the HFS filesystem from a Linux client running as a 
zVM guest, you will need the mvslogin RPM package so you can authenticate 
against RACF. In our shop we have be using this approach for several months and

Re: Secure FTP Server

[José L . Ramírez]

Hi Charlie,

We had basically the same situation; we ended using zOS as our corporate FTP 
server. That way we can use RACF to authenticate users and for external users 
it looks like just another UNIX server. The zOS FTP server has everything you 
need to provide SSL/TLS capabilities. 

In our case we receive many encrypted files (ej. PGP) directly to zOS and then 
using the zOS NFS server a zVM Linux guest performs decryption of the files 
using GnuPG.

Hi Sipho,

Maybe you can clarify what you mean by saying that the "NFS server and client

as a vm guest?

The zOS NFS client is capable of accessing any NFS server, no matter where that 
server resides, it may be the MVS NFS server, UNIX flavors (AIX, LINUX, 
Solaris, etc.). You may like to take a look at the z/OS Network File System

MVSLOGIN for x86 Linux

Good evening,

 

I think a similar question has been posted on the past, but what I'm looking is 
to see if anybody has been able to create a binary of the mvslogin program on a 
x86 Linux using the sources provided by IBM on zOS. Our company will be doing 
the annual disaster recovery plan very soon and we will like to do some tests 
with a SUSE 9 linux guest that is currently running under zVM, but at the 
recovery site we will not have zVM, instead we will get an x86. The mvslogin 
program is crucial for us because in our production environment the zVM guests 
access data from zOS using the zOS NFS server.  Any feedback is really 
appreciated.

Hi,

The server we intend to recover is used to encrypt/decrypt data, basically it

We need to access the zOS server in order to access some application data on

Well, it depends on what they mean by "recovering."

If you already have the x86 equivalent of the app environment set up,
and all you're recovering is your data (or, possibly, some byte-
compiled applications--I mean, isn't that the promise of Java?
"Write once, crash anywhere") then, yeah, it could work.

Or, if you were really studly and had some way to recover your DASD
into Herc-compatible CKD files, then you could run your Linux guest
under Hercules (not likely, though, since you most likely have QDIO
devices coupled to a guest LAN or a Vswitch and Herc doesn't do QDIO
natively yet) on an x86 box.  Or Flex/ES plus a FlexCub would let you
do this directly, although in that case I'd argue that you aren't
*really* recovering to x86, you're recovering to s390/zSeries in a
funny-looking box.

However, yeah, the naive approach is certainly doomed.

We have reported a similar problem where a Linux server -will- ping a peer on 
the same Virtual Switch until such time as the Linux server shuts down and 
reboots.  After the reboot a Linux server can -no longer- ping another Linux 
server on the same Virtual Switch.  Odd.  But very repeatable.  The 
circumvention is to shutdown Linux, log the virtual machine off, log back onto 
VM, then reboot Linux.  

In other words, a virtual machine reIPL leaves to servers unable to speak to 
each other, although they can speak to the outside world.

I am suspicious of VM63895.  IBM suspects a difference in the VLAN tagging of 
the frames.  I wonder why a reIPL vs. a logoff/logon should matter, with regard 
to VLAN tagging.  But I readily admit that this is an area of TCP/IP where I 
have limited skills.  (PMR 57324 may be of interest to any IBMers.)

Hope this helps!

How Linux is running, Lpar mode or under zVM?

What hardware do you have? z/890? z/990? There is a known bug within the OSA 
card and one of the symptoms is that during installation the gateway address 
can't get pinged, check your OSA microcode level. See page 92 of this RedBook 
for more details: http://www.redbooks.ibm.com/abstracts/sg246695.html 

Regards,

Jose

Subject: help needed, can not ping itself during ipl

I am  still struggling on my first linux ipl from tape. Fortunately I could 
show my OSA card to linux 390 today.  
But still I have network problems.  During the network setup portion of the 
linux/390 ipl, linux  can not ping  its own ip address(gets unknown host), can 
not ping  the gateway ip address(gets unknown host),  pings the DNS server ip 
address and gets a proper reply.  But since it cannot successfully ping the 3 
addresses , network setup stops. 
It says,  I cannot ping all the required interfaces, correct the problem and 
stops. 

Then, a few seconds later,  I send the ping command to linux on the hmc 
console, it pings all the 3 addresses successfully.   Did anybody have this 
problem?  What should I do?

I have the ip address of linux placed in the lan dns server, still  have 
problem.
Thanks.
inci

Re: pgp vs gpg

[José L . Ramírez]

Hi,

We have been using GPG for several years and we haven't had any issue of 
compatibility, first we start using gpg on RedHat Intel and now we are running 
gpg under zLinux (SUSE).

There are commercial products that runs under zOS that are compatible with PGP 
(Megacryption and Mcafee).

Jose

Pure-ftpd & Firewall

[José L . Ramírez]

Hi,

 

We are trying to "open" a pure-ftpd server with SSL support (SLES9) so that 
external customers can transfer files to us in a secure manner. Internally 
everything is working fine; we are able to connect to the server using an SSL 
FTP client (Filezilla). The problem is with external connections, after the 
client accepts the certificate and authentication takes places, the connection 
is "broken", this happens with both active and passive mode. We are specifying 
the parameter PassivePortRange in the pure-ftpd.conf file and we also opened 
the port range specified in the PassivePortRange in the firewall. Does someone 
have been able to successfully implement something like this?

 

Thanks.

Has the client opened the necessary holes in their firewall as well?  The 
downside of encrypted FTP is that the PORT command can't be seen by 
stateful firewalls.  Hence the need for PassivePortRange.

As a guess, everything works until a DIR, NLST, GET, or PUT is issued? 
I.e. HELP and SYST work ok after sign-in?

I don't know if this happens automagically on SLES or not, but something 
similar has to be done on _any_ Linux system running iptables.  If you aren't 
running a firewall on your system, then of course it's not necessary to do 
this.  I.e., if the only firewalls involved are _external_ to your Linux system.

core9CD2
core9CD3
core9CD4
core9CD5
sp3CD1
sp3CD2
sp3CD3

4) updated the instorder and order file from the /suseinstall/yast

my instorder looks like this:

/core9/CD1
/core9/CD2
/core9/CD3

Then i enter userid and password and then start yast.
When i run YAST, after the disk configuration , i keep getting the
following error under "SOFTWARE":

Can anyone tell me how to isolate this further ? Does this mean i have a

I tried just putting the sles9/CD1 and core9/CD1 on the instorder and order
file. but i still get the same message.

Not to sound coy, but I want the best of both worlds.  ;-)

Primarily I need a DR solution; mainly to be able to bring the system
back from a disaster in under a week. There are already DR processes in
place for other systems on the mainframe(s), such as MVS, CICS, etc. I
am behind on z/VM in that regard. I took Steve Frazier's suggestion to
heart and started reading up on DDR. I've backed up z/VM with DDR in the
past, but I have yet to try it with the DASD used by the Linux guests.
Given what I already know about using DDR with the system volumes, I'm
sure I could stumble through it. What I hoped to do is get some sort of
automated backup established for both DR and application data. I've sent
inquires to our VAR for information on BrightStor VM:Backup and IBM's
Backup and Restore for z/VM. We'll take a look at both of those products
and see what fits. My biggest interest was leveraging our VTS. I can
easily walk out on the raised floor and swap tapes, or perhaps have an
operator take care of it, but automation has so much appeal.  :-)

To answer a couple of questions already posed to me in this thread:

1. Yes, I am interested in learning more about the free front-ends for
DDR that have been written by folks on this list.

2. I didn't post to the VM list because I felt that cross-posting might
have been frowned upon...

3. Dennis asked if I was going to take the guests offline while doing a
backup. Yes, that was my plan. I have one day a week when there's no
workload on any of the guests, so I can take advantage of that in the
short term.

My sincere thanks to everyone that's responded to my questions.

Are you looking for Disaster Recovery backups of z/VM and Linux DASD? Or
are
you looking for file level backup/restore for these systems? 

For DR purposes, DDR or other programs can dump/restore all of your DASD
to VTS
tapes. Mounting the VTS tapes requires DFSMS/RM and is enhanced by tape
management products (VM:Tape from CA, Tape Manager from IBM), but it can
be
done from scratch (not nicely yet). 

For file level restores, there is no one program that can help you. For
z/VM,
you can buy products (VM:Backup from CA, Backup/Restore Manager from
IBM) or
code your own around the CMS TAPE or VMFPLC2 commands. Again DFSMS/RM
talks to
the VTS and a tape management program helps. For the linux files, you
need a
linux program like Amanda or Bacula, both of which are free and can
write to
the VTS drives. You still need DFSMS/RM and an interface program from
Sine
Nomine (http://www.sinenomine.net). 

My bosses have not purchased any products to help backup/restore any
level of
z/VM or Linux data so I can sympathize with situation.

Re: How do you configure your WAS servers?

[José L . Ramírez]

Hi,

We have one guest running WAS, this is how my USER.DIRECT looks:

USER LINUX009  1536M 1536M G

 OPTION QUICKDSP 
 IUCV ANY
 IUCV ALLOW  
 LINK MAINT 0190 0190 RR

Right now we are running the web server on the same WAS app server... but this 
is going to change because we just recently finished testing two apache servers 
(connected via heartbeat).

Subject: How do you configure your WAS servers?

(I am cross-posting this message to the linux-390 and IBMVM lists.)

We are going to be getting into using WebSphere and HATS at my shop.  
We have 1 IFL running VM, with Linux guests.  Most of the configuration 
information I have seen presumes standalone boxes rather than a virtualized 
environment.  I have a couple of questions for those of you who run WAS on 
Linux under z/VM, or at least those of you who are inclined to answer:

Do you run your web server(s) on the same image as your WebSphere app server or 
use a separate image strictly for the web server?

How big do you make your WebSphere images; that is, how much virtual storage do 
you assign in USER DIRECT?  How much swap space do you give them?  

Do you cluster your WAS images?  

Thanks in advance for any information.

Jon

Re: Article for z/Journal

[José L . Ramírez]

Hi,
 
I have been working with mainframes for about 12 years (I'm 32)... I started as 
an application programmer and the moved to system programming about 8 years 
ago...
 
What I'm seeing is something similar to what Ruddy described. In my company we 
are running all the core systems on the mainframe but a decision has been 
already taken and now everything is going to be migrated to a .NET MS 
environment. What runs on a singe z890 will require at least 50 Intel servers 
and counting... 
 
For the last three years I have working directly with zVM and zLinux and we 
have been able to show management some of the benefits of an environment like 
this, but as Ruddy said, MS has a great marketing team... we even tried to 
start using Open Office on the desktop but as soon as MS saw the move they 
"convince" management to continue using MS Office.
 
Part of the problem is that people still think the mainframe is a BIG machine 
with green terminals... we have done an "experiment" here in the data center in 
which we ask people to identify the mainframe in the server room, almost nobody 
is able to identify the z890 and some people believe the mainframe is the air 
conditioner unit...

Let's hope that IBM can "revive" the mainframe so that it can continue to be 
the best server in the data center...

Subject: Re: Article for z/Journal

I am a graying mainframer.  I worked for IBM for 28 years as a hardware
servicer, marketing system engineer, and a mainframe contract employee.


I am concerned that three universities in my area were deeply involved
in mainframe systems education in the past but now focus only on
Microsoft products.  There is no effort in this area to educate students
on mainframes and their potential.

I currently work for a state agency that provides data processing
services to other state agencies (similar to a service bureau).
Although the core applications (finance, welfare, labor) are still
housed on the mainframe, there is a concerted effort by the CIO to move
all applications to a client/server/web environment.  To him this means
everything will run on an Intel platform with a Microsoft operating
system.

Everyone in my work section is 40 years old and up.  We recently had
five employees leave. One passed away, three retired and one reassign to
another area (help desk).  Only two people have been recruited to
replace these employees.  The replacements have been mainframers from
other agencies.  These agencies have been moving to Intel servers for
all new applications.

Microsoft has done a great job in marketing their products as the future
of data processing.  They did this by capturing the education of future
programmers and data processing employees in the universities.

The personal computer has helped by enabling everyone to think he is a
computer expert if he can load and run software on his own machine.  The
bulk of the people in the data processing industry have little or no
contact or exposure to the mainframe.  They have no concept of the
potential of a single mainframe processor.  Their concept is to run each
application on a separate server regardless of the interactions of the
numerous applications in each and every organization.  Whatever happened
to having a single source of data so that the data is in sync, up to
date and accurate?

Some of this has been caused by the cost of mainframe software and the
time required developing applications.  In today world this is no longer
the case.  We have desktop development tools for mainframe applications.
We can even develop web applications that are more reliable and faster
than their Microsoft counterparts.  CICS, IMS, and DB2 are still great
application environments.  Today's application developer just is unaware
of their potential and versatility.

Thanks for the opportunity to vent my frustrations.

Long story short, we're looking for an FTP server that will compile on SLES9 on

performance comparisons with an FTPS product that we are testing on VSE.

While we could test it easily on a Windows box, I don't consider that a valid 
comparison. I'd rather perform comparison on the same hardware platform.

If SSL is the issue you can setup your ssh logon to be SSL and the sftp
will then be encrypted.

As Mark pointed out I believe vsftpd is supposed to support FTPS.
Not sure if vsftpd has provided the full data encryption yet.
You may want to check out WS_FTP Pro I think it supports  FTPS with SSL but
is a fee based solution. They do have a trial period.

Do you have CUPS set up to do lpd emulation on port 515 (I think)?

If not, well, you can't print because nothing's listening to the lpd
port.  Cups by default uses IPP, which is 631, I think.

3. Enter the hostname & remote queue name
4. Enter Name (ex. test)

Then from the command line --> lpr -P name-of-printer document-to-be-printed

something loose for you. If not, they'll find out why. 

Also, there's probably some one around DC who'll spare you a morning to
get you started on your VM install and ops. It's really one page; not
much to know, and remember, the first taste is free...8-) 

VM is addictive; one look and you'll wonder why you ever put up with
LPARs...8-)

Re: Linux Network problem using VSWITCH

[José L . Ramírez]

Hi,

In the past I had a similar problem but don't really remember if I was still on 
zVM 4.4 or zVM 5.2. The problem was fixed after applying the latest maintenance 
to zVM.

Regards,

-Jose

Subject: Linux Network problem using VSWITCH

I have a default VSWITCH defined and connected to my OSA express card. z/VM 5.2.

The following userids are coupled to the VSWITCH. Q vswitch detail output at
end of note.

TCPIP (142.214.154.50)
LINUX02 (142.214.154.42) (SLES10)
SLES10 (142.214.154.51) (SLES10)
LINUX04 (142.214.154.44) (SELS10)
LINWAS (142.214.154.45) (SLES9) 

Gateway IP is 142.214.154.1 
Mask is 255.255.255.128

From LINUX04 I can ping TCPIP but not LINUX02 or SLES10 
From TCPIP I can ping all Linux systems
From LAN (142.214.195.65-different subnet) I can ping all. 
Problem: I can not ping from any of the linux guest to any other. 
My route on linux is a follows:
route
Kernel IP routing table
Destination Gateway Genmask Flags Metric RefUse Iface
142.214.154.0   *   255.255.255.128 U 0  00 eth0
link-local  *   255.255.0.0 U 0  00 eth0
loopback*   255.0.0.0   U 0  00 lo
default 142.214.154.1   0.0.0.0 UG0  00
eth0LinuxSLES10Controller:~ #
My IFCONFIG is
ifconfig
eth0  Link encap:Ethernet  HWaddr 02:00:00:00:00:02
  inet addr:142.214.154.51  Bcast:142.214.154.127  Mask:255.255.255.128

  RX bytes:47792 (46.6 Kb)  TX bytes:47792 (46.6 Kb)
I can't see why this shouldn't work 

Now here's the scary part: I changed the routes file on LINUX02 to 

Default 142.214.154.1 255.255.255.128

and recycled the network card. I was then able to ping LINUX04 and I think it
worked because it went out to the gateway. I was not able to ping LINUX02 from
a different subnet on the LAN so I changed back the route default to 0.0.0.0. 
By doing this both LINUX04 and LINUX02 can ping each other but I still cannot
ping SLES10. Did VSWITCH record/map the IP address to the MAC address or
something? Do I need a fix?

Any comments/suggested are greatly appreciated.

Thanks Hans Rempel
