I have a good SDL-Hercules setup for VM/ESA V2.4 now. I can start and stop
it and login to MAINT or any of the other pre-configured users and shut it
down normally. All this is done with TK4- based automatic startup and
shutdown scripts.
I found somewhere in the VM/ESA documentation that the system supports a
maximum of 2047M in main storage and a separate maximum of 2047M in expanded
storage (XPNDSIZE in the Hercules configuration file). I am able to use
ARCHMODE ESAME and CPUMODEL 9672 without problems so far.
Now I want to configure the TCPIP setup.
The preconfigured system defines two external communication devices, 448 for
"VTAM SNA" as a P/390 "LAN3172" device and a pair of P/390 "LCS3172" devices
at 44A-44B for TCPIP.
My understanding at the moment is that Hercules does not yet support the
SNA-based "LAN3172" device, is that correct?
LCS3172 devices are known to me from configuring other IBM OS systems under
Hercules. My Hercules configuration statement for the TCPIP devices is:
044A-044B LCS -n 192.168.1.8 -m 02-AA-BB-CC-DD-EE 192.168.1.81
Where 192.168.1.8 is my host system Win10 IP address and 192.168.1.81 will
be this VM/ESA's IP address.
All good so far.
In the PROFILE TCPIP file under user TCPMAINT the pre-configured system
defines the 44A address as a token-ring device rather than as ethernet, so
the first change is to make it ethernet:
; 3172 44A/44B ETHERNET
DEVICE UNITY LCS 44A
LINK ETH44A ETHERNET 0 UNITY
The PROFILE TCPIP file also uses a range of 9.x.x.x IP addresses which I
presume I need to change to 192.168.x.x addresses, starting with the HOME
address and ignoring the static route definitions for other local systems
for now:
HOME
; local host InterNet addresses (SYS1)
192.168.1.81 ETH44A
; (End of HOME address information)
GATEWAY
; (IP) Network First Link Max. Packet Subnet Subnet
; Address Hop Name Size (MTU) Mask Value
; ----------- ------------ ------- ----------- ----------- --------
192.168.0.0 = ETH44A 1492 0.255.240.0 0.168.0.0
DEFAULTNET 192.168.1.1 ETH44A 1492 0.255.240.0 0
; (End of GATEWAY Static Routing information)
My router is at 192.168.1.1, is the 192.168.0.0 gateway definition correct
in the above change? I am especially unsure of the "Subnet Mask" and
"Subnet Value" settings, are they correct for a 192.168.x.x local network?
Then there is the HOSTS LOCAL file where the 9.x.x.x addresses also need to
be changed and I would comment out the "other" systems for now:
HOST : 192.168.1.81 : SYS1.P390.MYDOMAIN.ORG, SYS1 :::: ;
; HOST : 192.168.1.82 : SYS2.P390. MYDOMAIN.ORG, SYS2 :::: ;
; HOST : 192.168.1.83 : SYS3.P390. MYDOMAIN.ORG, SYS3 :::: ;
; HOST : 192.168.1.84 : SYS4.P390. MYDOMAIN.ORG, SYS4 :::: ;
Am I missing any other changes to get TCPIP up and running? Are any of the
changes I listed above incorrect?
I do know I may need to update the FTP server data file(s) but I thought I
should just start with basic TCPIP changes to begin with.
TIA for any assistance you can offer.
Peter
