VM User ID or z series LPAR name under RHEL4 U3
Is there a way to get the VM 5.2 user ID or the z series LPAR name under Linux? What I would like to do is use this to determine the hostname and the IP address of the Linux system, instead of having to change it in each one.

Re: VM User ID or z series LPAR name under RHEL4 U3
The CP QUERY USERID command can be issued a variety of ways from a linux virtual machine. from a 3270 use #CP Q USERID within linux you can install and use: Neale Ferguson's CPINT package IBM vmcp driver If you are on a vswitch (as I recall when we chatted in Tampa) do from TCPMAINT or MAINT CP QUERY VSWITCH DETAILS I love the command, it includes the names of all vm's using a vswitch and the ip info.

What I would like to do is use this to determine the hostname and the IP
address of the Linux system, instead of having to change it in each one.
1. Use a layer 2 VSWITCH and put a DHCP server on it (see prior posts
about needed Linux qeth config changes)
2. Assign a unique MACPREFIX to your system in SYSTEM CONFIG. The
MACPREFIX is the high-order 3 bytes of the MAC address.
3. Predefine the MACID on the NICDEF in the directory. This is is the
low-order 3 bytes of the MAC address.
4. Concatenate the MACPREFIX and MACID to get the MAC address of that
particular virtual NIC. Put that information in the DHCP configuration
for static assignment.
Given MACPREFIX 020001 and MACID 50:
host alan {
hardware ethernet 02:00:01:00:00:50;
fixed-address 192.168.1.50;
}
-- or --
host alan {
hardware ethernet 40:00:80:00:00:C0;
fixed-address 192.168.1.50;
}
(I can't remember whether the VM-specified MAC address is reversed by the
time it reaches the canonical format or not.)
If you already have a DHCP server on the LAN segment (even if not on VM),
add the MAC address/IP info to that server instead. (I haven't seen any
dhcpd config options to limit the MAC addresses it will serve.)

Ok, you're going to have to explain this one. Exactly in what way is
02:00:01:00:00:50 a reversal of 40:00:80:00:00:C0? That doesn't look right,
even if you reverse the bits in each hex character.

Re: VM User ID or z series LPAR name under RHEL4 U3
If you already have a DHCP server on the LAN segment (even if not on VM), add the MAC address/IP info to that server instead. (I haven't seen any dhcpd config options to limit the MAC addresses it will serve.) One easy way (at least with dhcp3) is to define a group, and put the MAC addresses of the hosts into the group entry. You can then specify the group in a 'scope' entry, and the DHCP server will serve only members of the group with that scope. If the MAC address does not qualify for membership in the scope, no answer is returned to that MAC address. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: VM User ID or z series LPAR name under RHEL4 U3
Modern DHCP servers don't require the bit reversal evil any longer. It was much more of a big deal for token-ring adapters than Ethernet, anyway. Use the canonical form everywhere -- it's Just Right. It would be interesting if VM set the default MAC prefix to one of the user-managed spaces as the systemwide default, though. Oh, well, another requirement...8-). -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
