Have a 5.0.4 Ent server which mounts an NT share via "Diskshare or OmniNFS".
We have moved the NT server onto a different network. IP address of Sco is
215.12.66.9/255.255.255.0, NT box is now 215.11.66.20/255.255.255.0.
Connecting over a 2Mb router with 215.12.66.215 at one end and 215.11.66.100
at the other. I'm trying to enter a perm. arp entry using arp -s on the SCO
box but I'm getting the following error: "Set: can only proxy for
215.11.66.20" .
What does this mean? Why can't I add this perm.arp entry?
I'm assuming my RPC portmapper errors are because of this.
Help....

No. Your paraphrased portmapper error message is because you followed
instructions and used "netconfig" to change system names and IP
addresses. One feature is to create duplicated entries for the server
in /etc/hosts. Edit /etc/hosts manually and remove the bogus entry.
The portmapper complaints on startup should cease.

Now comes the real challenge. netconfig does not change every
instance of machine name and IP address. See:

for a shopping list of files that need to manually checked and
tweaked.

I've followed that for safe measure but it's not the Sco box that's changed
IP, it's the NT one. (And yes, I know this isn't an NT forum...). My
instinct tells me this is a Sco problem as I cannot get the mac address/IP
address mapping in arp properly. All I'm typing is arp -s 215.11.66.20 [mac
address].
I can ping the NT box, but the first two pings take a collective 5 seconds.
I've run traceroute and the first hop is indeed the router, but it's getting
as far as the router then it's getting lost.
Oh the joys of an SAP migration !!!.....

OK. Let's start over.

Missing Information:
Patches and fixes added to 3.2v5.0.4. (customquery listpatches)
Details on portmapper error.

1. What does:
arp -a
belech?
2. Is there an existing arp entry for the IP address you're trying to
map?

I'm trying to figure out why you need to map the MAC address manually
in the first place. If you just ping the router, the MAC address
should appear in the arp table without exernal assistance.

OK. Now, I'm lost. If this is an ethernet to ethernet type of
router, then you have *TWO* MAC addresses to deal with (one each for
each ethernet interface). Whether you see the other MAC address on
the other side of the router is totally dependent on whether you have
bridging turned on in the router. I don't see why you should have
bridging on, so you'll only see one MAC address. Since I have no clue
as what brand or flavour of router, I can't offer specifics.
2Mbits/sec would probably be an RF wireless bridge. Details (I'm
curious).

>Oh the joys of an SAP migration !!!.....

Sheesh. You have it easy. I did a conglomeration of two companies
sharing a common server, where neither company wanted to change IP
addresses. Two ethernet cards in every server in the place with
routeing disabled. I'll trade you nightmares any time.

I dunno. Nothing in the SCO docs. I can't even figure out where the
error is coming from. Any chance you have the Netscape Proxy server
running on OSR5?

>I'm assuming my RPC portmapper errors are because of this.

What error? I'll assume it's the SCO Unix box. Exact error please
and no paraphrasing. At what point does the error appear? Startup or
when you run arp?

With all due respect, you're not supplying enough information for a
decent answer. However, I do have some guesses. I'll *ASSUME* that
the SCO Unix box and it's friend the router were working as expected
prior to the addition of the NT server.

Look in:
c:\winnt\system32\etc\hosts
c:\winnt\system32\etc\lmhosts
and see if there isn't some residue from the previous IP addresses.
Also check if DNS, WIN and DHCP do not have some residue.

Check the OSR5 box for the Netscape Proxy server and kill it.

??

No, my point exactly, When I do ping the router I get no entries in my arp
table. One of the quick fixes we've used on other clients (as the routers in
question don't support Supernetting) is to add manual/static arp entries.

The landscape is
215.12.66.9 (Sco) --> 215.12.66.215 (onsite router) -->[2Mb British Telecom
Fibre] --> 215.11.66.100 (offiste router) --> 215.11.66.20 (NT Box)
All subnets are straight class C. The routers are Bay Networks routers
although I'm not sure of the model number.

"RPC Portmapper Error: Connection refused" or " RPC Portmapper Error: Cannot
connect to Electra:/e/" (Electra is the NT box)

I'l check, and I'll update when I have some more solid info. My worry now is
that the Sco box is shafted as I tried reinstalling NIC & Sw and am getting
the following error:
Redefined boot_net0
kslgen: cannot fine major/minor device number for /dev/net1.

What worries me is that I don't have a net1, just a loopback, one nic and I
did have PPP some time agao which I took off. The one Sco doc that refers to
this (107625) suggests that I hak my /etc/strcf file and immediately find
the problem - duplicate entries. Neither that file, nor the
/etc/strcf.d/10tcp file contained dup entries so I'm currently trying to
find what refers to the /dev/net1 device so I can get rid of it.
