getting Hercules to accept my CTCI-W32 device definitions. I've
enabled IP Forwarding in Win2K. (IPCONFIG confirms that IP Routing is
enabled.) I've built IPL tape images for SuSE and RedHat flavors of
Linux for S/390. I even built DASD images in preparation for
installing one of the above mentioned flavors. I've IPLed both
versions from tape repeatedly while tweaking Kernel parms, Hercules
parms, and heaven know what else. I can ping the Linux local address
and the "host" adapter address, but not the DNS servers from SuSE
(RedHat doesn't include ping in its RAM disk image). I can also ping
the local address from Win2K.
What I cannot do, with either flavor of Linux IPLed, is telnet or ssh
in to start the install process. Since I can't ping outside the scope
of the Win2K "host", I assume I would also be unable to access the FTP
server where the installation CD images for both flavors await, but
that's another story. Using the Putty client, there are no messages,
and the connection drops instantly. Cygwin's telnet client responds:
Connection closed by foreign host.
SuSE (but not RedHat) also issues the following messages through the
suse in.telnetd 211!: connect from 220.127.116.11 (18.104.22.168)
suse telnetd 211!: ttloop: read: Connection reset by peer
suggesting that the Telnet server was at least aware an attempt was
made to connect.
I am not particularly skilled in matters networkish, but am
most willing to learn. Does anyone have any ideas or suggestions?
