VNC JavaSecurity Error

[Walters, Gene P]

I am installing SuSE 11SP3, like I have done many times before, however this 
time when I get to the part where I bring up a web page and go to the new 
instance to start a VNC session, it tells me that my security settings wont let 
me run the old version of Java that is being downloaded from the VNC server(the 
new Linux instance).  Any suggestions on getting around this?

Re: Performance Toolkit and zLinux

[Bill Bitner]

The RMF agent that runs inside the Linux on System z guest was
re-written the other year and changed the interface. We chose not
to update the Performance Toolkit handling of that interface as
other things have changed since the introduction of the RMF agent
to Linux. You can still use the RMF client (the link provided
earlier will point to information ont that) that supports z/OS as
well. There was a statement of direction in 2011 for these changes.

Performance Toolkit will report on the z/VM Appldata that Linux
provides on all the current distributions. While this doesn't
provide process level information, it does provide a Linux view
of some important metrics. It is also very low overhead.

Additionally, OMEGAMON XE for z/VM and Linux provides both the z/VM
and the Linux agents. Perhaps not the first choice for a PoC, but
wanted to mention for completeness.

Re: Performance Toolkit and zLinux

[Tom Huegel]

Although zVPS is a fine product and I am sure well worth the price it
provides much more than the basic information I am looking for.

All I need in my lab on the occasions when someone wants to run a zLINUX
guest is provided by the APPLdata and PTK.
Thanks Berry.
A GOOGLE search pointed me to an OMEGAMON doc with instructions to enable
data collection.

Re: Error when load z/Linux for first time

[Martin, Terry Contractor]

Ok. I got a z/VM MD5 checksum from Dave. We ran it against the INITRD IMG and 
KERNEL IMG files and sure enough they did not match the MD5 value that was sent 
with the RHEL ISO for these two files. So the assumption is corrupted files. 
The files we downloaded from the HTTP source server to our workstation are 
good. We ran a MD5 checksum on those and they match.

Our initial load of these files from our workstation down to z/VM was via the 
PCOMM terminal emulator SEND/RECEIVE.  We MD5 checked these files and they 
don't match.

So since we have some security issues at this shop currently using FTPSERVE we 
tried using FTP to move the files from our workstation to z/OS and then FTP 
from z/OS to z/VM. Note using FTP all the way through.

We than did another MD5 checksum on the files on z/VM and they still don't 
match. So it looks like something is happening to the files on transfer to z/VM.

Any help or ideas?

Thanks,

Terry

Sounds like a problem in the browser.

What browser are you using?

Have you looked at the security settings of your browser?

We ship a Java based VNC client, and have encountered problems
with:
- the Code Signing of the .JAR file had expired, and
so a local Java installation refused to run it, deeming it
insecure. Solution was to update what we shipped with a more
corrent copy
- the Java on the local machine, which was being
started by the browser, was 'stale' and had been updated
upstream; Solution there was an update of that Java (This
especially seen on OS/X units)
- the Code Signing key used to sign the .JAR was
counteresigned by a CA (Certificate Authority) not known to
the local Java installation.  Solution was to add that CA's
'chain of trust' into the local ancillary install for the
local Java install

Reading the messages closely is needed, to understand what is
in play

Re: Error when load z/Linux for first time

[Martin, Terry Contractor]

Ok, we finally got this to work. Ultimately we had to get FTP working and load 
using that. Even though the MD5 checksum done on z/VM against the images loaded 
on z/VM showed a different DISGEST value for the INITRD and KERNEL images from 
the original HTTP server source (ISO) we tried it anyway. Well it worked! So 
the difference was how we got it from our workstation to z/VM, which was using 
FTP instead of the PCOMM terminal emulator SEND/RECEIVE.

Not sure why the MD5 checksum did not match but I will talk to Dave to see If 
he has any idea as to why.

Thanks for the help and hope this helps other folks who may run into the same 
issue.

Terry

KERNEL IMG files and sure enough they did not match the MD5 value that was sent 
with the RHEL ISO for these two files. So the assumption is corrupted files. 
The files we downloaded from the HTTP source server to our workstation are 
good. We ran a MD5 checksum on those and they match.

Our initial load of these files from our workstation down to z/VM was via the 
PCOMM terminal emulator SEND/RECEIVE.  We MD5 checked these files and they 
don't match.

So since we have some security issues at this shop currently using FTPSERVE we 
tried using FTP to move the files from our workstation to z/OS and then FTP 
from z/OS to z/VM. Note using FTP all the way through.

We than did another MD5 checksum on the files on z/VM and they still don't 
match. So it looks like something is happening to the files on transfer to z/VM.

Any help or ideas?

Thanks,

Terry

Hadn't been following this..   we had the same issue ...  I ended up doing
a VMARC of the INITRD file on one system -- then using 3270 file xfer to
download/upload that to the other z/VM system and it was usable after
unpacking with VMARC.   FTP wasn't an option at the time to the target
system..   Still not sure why 3270 file xfer didn't work to xfer it ..  it
has in the past with other install files..

Re: Error when load z/Linux for first time

[Mauro Souza]

The MD5 sums will never match, because zVM uses a 80 char "line lenght" and
Linux does not. So the file md5sum sees on Linux is not the same it sees on
zVM.
I had enough problems with SEND/RECEIVE to give up on it permanently. I
always try to FTP large files (larger than 1MB), by PUT or by GET. Some
corrupted transfers still happens, but they are very, very rare.

Re: Error when load z/Linux for first time

[Scott Rohling]

p.s.  We had to FTP the initrd image to a z/VM system where we had FTP
access -- then do the VMARC -- so ultimately - FTP was the answer -- the
VMARC stuff just helped get it to this other system without being garbled.

Re: Error when load z/Linux for first time

[Scott Rohling]

Just curious - couldn't you have FTP'd to the server where the .iso image
is and done a GET of the install files?   Using z/VM as an FTP server was
not an option in our case -- nor was reaching the install server via FTP
from z/VM -- that's why I 'had' to use 3270 file xfer and resorted to
VMARC, etc.

But it sounds in your case like you could have reached the install server
from z/VM via FTP rather then have to do a workstation shuttle or get
z/VM's FTPSERVE working?Or is this what you did do and I just misread
your post?

This and the Code Pages observation Dave Stuart made ... no, no, MD5
(and other hashes) is a binary checksum. It should ignore record
boundaries. (Discussion grows long from here.) If record boundaries are
significant, then you're talking about some plain text file which must
be translated perfectly before being subject to hash/checksum.

Byte-for-byte MD5 (and other) checksum should match between CMS and Linux.
Witness the many download sites and public repositories which include
MD5 and/or SHA-1.
The hashes are excellent for assuring the transfer did not clobber the
file.

I agree there should be better "text checkers", but was shot down in the
days when MIME was first introduced. (I wanted them to ignore linear
white space in some comparisons. CMS to date does not support truly
empty records in minidisk or SFS files. Makes email quirky to process.
What a pain.) But MD5 is binary.

Guessing my earlier reply got whacked by LSV. Sorry. I know better but
had forgotten to remove the signature magic.

Re: Error when load z/Linux for first time

[Martin, Terry Contractor]

Scott,

We could not get to the Server that the source was on. That is why we 
downloaded to the workstation. From there we used FTPSERVE to get it in z/VM.

Just curious - couldn't you have FTP'd to the server where the .iso image
is and done a GET of the install files?   Using z/VM as an FTP server was
not an option in our case -- nor was reaching the install server via FTP from 
z/VM -- that's why I 'had' to use 3270 file xfer and resorted to VMARC, etc.

But it sounds in your case like you could have reached the install server from 
z/VM via FTP rather then have to do a workstation shuttle or get
z/VM's FTPSERVE working?Or is this what you did do and I just misread
your post?

Re: Performance Toolkit and zLinux

[CHAPLIN, JAMES (CTR)]

Tom,

Look at RMF XP, 
http://pic.dhe.ibm.com/infocenter/zos/v1r13/index.jsp?topic=%2Fcom.ibm.zos.r13.erbb200%2Fgpm4cim1.htm,
 you can download the implementation guide at: 
ftp://public.dhe.ibm.com/eserver/zseries/zos/rmf/rmf_xp_implementation_guide.pdf
 as “rmfpms” replacement.



Quote:
“RMF XP exploits the existing Common Information Model (CIM) instrumentation 
for AIX and for the Linux distributions (RHEL/SUSE) and does not require any 
proprietary agent software on the monitored endpoints. The CIM server, as well 
as the metric providers, are integral parts of the supported AIX and Linux 
distributions, and therefore no additional software needs to be installed. 
However, you need to ensure that the CIM servers with their metric providers 
are properly set up and running on the monitored endpoints. This document helps 
you in configuring the CIM servers and their metric providers and gives you 
additional hints and tips on how to optimize your RMF XP configuration.”

Although zVPS is a fine product and I am sure well worth the price it provides 
much more than the basic information I am looking for.



All I need in my lab on the occasions when someone wants to run a zLINUX guest 
is provided by the APPLdata and PTK.

Thanks Berry.

A GOOGLE search pointed me to an OMEGAMON doc with instructions to enable data 
collection.

modprobe appldata_os

modprobe appldata_mem

modprobe appldata_net_sum
