Ah, you're right - that would be accouned as dropped, not TX error. Forget

It has been years since I was there but the Chicago Museum of Science and
Industry had great exhibit of computers.
I remember they had an IBM RAMAC 305 (I think it was working) along with
many other historic devices.
It has been quite a while since I was there, has anyone seen this exhibit
lately?
Berry,

Carsten,
Do you know where I would start looking for causes of the transmit errors on
Hipersockets?
The error is occurring on SLES11 SP2 systems. We are not having it on our
SLES10 SP4 systems.
Do I need to open a problem with the SuSe folks?
Thanks,

Saw one version of it a few years ago. I don't think their RAMAC works.

Ron,
Carsten's first explanation is correct. If you see tx_errors on a
HiperSockets interface, it usually means transmission of a packet fails
because the receiver has currently no free receive buffer. You should
verify first if the receiver has configured the maximum of 128 buffers
(sysfs attribu
Question: Why would SLES 11 see hipersocket retransmits and window adjustments
and not SLES 10? Is the device driver either more forgiving or efficient on
SLES 10?
I'm just curious. I may be in the same situation soon.

I know I've read how to do this in the past, but I can not find it anywhere
in my archives.
How do I determine what version of SLES I am running?

Hi Mark.
Run:
# cat /etc/SuSE-release
# uname -a
That'll tell you the version of SuSE and the kernel version + patches.

The receiver is zos. Anybody here know how to increase the buffers in zos.

I usually run
# cat /etc/*release
So wherever it's SuSE, RedHat, Ubuntu, Fedora or almost anything, I can get
the distro version.
And to get the kernel version:
# uname -a

Thank you both. I knew it was simple, but I just couldn't find it.
Now I need a better memory, because my main FTP server says it's SP2 and I
do NOT remember upgrading it. :(
Oh well, one less step to get it to SP3. :)
