Hi there!

Last weekend I tried to interconnect my Windows For Workgroups 3.11 boxes
to some of my Linux servers. I tried to make a network "share" on WFW,
which I wanted to be able to access from Linux. I.e., I wanted to copy my
MP3s and burn backups in Linux.

Something refused to work, I just could "see" the share, but it could not
be accessed. So I wanted to inpect what was wrong here - I made a
portscan from Mandriva Linux (2009.1) to WFW, to see if both Micro$oft
ports for "workgroup / network sharing" were open, but instead of
displaying a list of open ports NMAP just said the machine was down. Also
Ping didn't get an answer.

So I tried to ping locally from the WFW machine to a box in the same
100MBit/s network, but WFW said, there was a "Hardware failure"?! But:
After reboot the WFW machine was present in the network again. So I'm
pretty sure that Mandriva's NMAP crashes WFW3.11's TCP/IP protocol
stack...

The reason why I'm asking here is because a portscan from Mandrake 10.1
never did things like that, except, it made Texas FTPd on top of WFW
crash with protection fault Smile ...Well, Windows For Workgroups 3.11's
network processes don't seem to run this stable...

Any idea what changed between NMAP (or the whole TCP/IP stack) from
Mandriva 2009.0 to 2009.1?

Well, this is not a serious problem to me, but I'm intereseted in that
penomena as an "academical" aspect Smile))

Any idea?

Best regards,

Markus
