DECnet installation

[geir_2]

Hi,

I have installed DECnet on a workstation, but I have trouble to access other nodes/hosts. I can use " $ set host 0" command with success, but if I use set host command to a different node, I got following error:

%SYSTEM-F-Unreachable, remote node is not currently reachable"

I assume that I have som trouble with device name ewa-0. Any ideas?

Geir,

did you use DECnet IV or V? Have you run the configuration utility (NETCONFIG or NET$CONFIGURE), any error messages?
Have you tried SET HOST with an address to exclude errors with node registration?

Hi,

It's DECnet IV. I have run netconfig-utility, and it's no error message.

If I reboot the system, the system have some trouble to recognize the ewa-0 device.

Hi,

More informations. If I run netconfig.com, everything seems to work. But if I use the startnet.com, I got following error message:

%NCP-W-invpva, Invalid parameter value, Physical Ethernet address Line = EWA-0

%NCP-W-UNRCMP, Unrecognized component, Circuit Circuit = EWA-0

$ show device e
ewa-0
ewa-1
ewa-2

PS:
The workstation is also running TCP/IP without trouble.

Hi,

If I start DECnet before IP, the problem was solved. Thanks.

DECnet 'writes' its own address to the MAC address of the interface. If it is in use by another protocol (e.g. LAT), this fails.
So you have to start DECnet before any other protocols.

Geir,

Please note that DECnet Ph IV must be the first protocol to start (because it tries to mangle the MAC address).

Place the call to STARTNET.COM before any other starts (e.g. TCPIP$STARTUP.COM).
