Hello Lily,

I've had simular problems setting up a Samba server. I'm also using SuSE
Linux 7.0 on a Linux/390 system. Only my link to the rest of the network
was thru escon channels.

The problem with me was the configuration of the escon link ip parameters.
Because it is a point-to-point link the netmask defaulted to
255.255.255.255, which is a broadcast address.  Once I changed that it
worked.

But since your ifconfig seems to contains a correct netmaks I'm a bit
stomped. Try asking on the linux-390 maillinglist. You will find more info
about this mialinglist here :

http://www.marist.edu/htbin/wlvindex?linux-390

There is also another problem with point-to-point links and Samba. The smb
protocols use network broadcasts a lot. And as you will see as you
compare the ifconfig of a normal ethernet link and a point-to-point link,
you will see that the p-t-p links don't support broadcasts.

So if you intend to run Samba on a mainframe and have a network that
doesn't contains other SMB services like a WINS and PDC, you will need to
run Samba of a image/LPAR that has direct access to a broadcast capable
device (ethernet, tokenring).

Tim
