You *can* use hipersockets to talk between Linux guests. If the guests
are running in the same z/VM system it makes more sense to use the
VSwitch, than to use hipersockets. Of course, if the Linux guests are
in different LPARs then you have to use hipersockets.
I defer the security aspect

Vswitch is internal to CP, hipersockets makes most sense to move data
between LPARs.
Using hipersockets requires a trip out of the VM system (even if it's
between virtual machines), whereas using the VSwitch stays within CP.

That appears to be dependent upon the traffic. If the choice is between
VSwitch and Hipersockets, then the traffic must be moving between
virtual machines. Why leave the VM system to move packets?

Terry,
The message

. It was balking about the MTU size being
invalid.
I was using 16384. I changed it to 1500 and tried the OBEYFILE command

and it worked.
I noticed on the NETSTAT displays that the MTU actually was 32768 with a

CHPARM=40. So
Hi
I am setting up HIPERSOCKETS for the first time and I am dealing with

trying to do

Make sure you use the 2007 version of the Hipersockets Redbook. I was
never able to get it to work with the 2002 edition.

Sorry for the late reply, I've been on vacation. (some of you may remember

I do not see where you would specify a port name on z/OS. I've tried to
remove the port names from the z/VM definitions, but thus far it has not
made a difference.

), and microcode check would pass. Eg, port names
HSOA1 and HSOB1 were OK, but not HSOB2. Later on I found out that this is in
fact how it worked. This applied both to hipersockets and OSA's. From z990
onwards, this slack was removed and from then on all port names must be
identical or not used at all
the z/OS guest,
connects
to the hipersocket and changes port name from nothing into something.
A mismatched port name on an OSA creates an initialization error. In any
case, HiperSockets do not have port names. On z/OS they are addressed
solely by chpid (DEVICE IUTIQDxx).
My apologies
Alan,
A mismatched port name on an OSA creates an initialization error.
Correct, but with a caveat explained in the other thread (yes for z990
onwards, before z990 one character could mismatch. I know it sounds weird,
but that's the way it worked)
In any case, HiperSockets do not have port

Does it make a difference that Hipersockets are real devices dedicated
to the z/OS guest and the OSA connection is a VSWITCH? The OSA
connection on the VSWITCH works, the real Hipersockets do not.

Try removing your port names and see if that works.
Port names are meaningful to z/OS, not Linux or z/VM. It is ok if some are
