[Linux-decnet-user] Lat interface detection

[BASSIR M. <Moh...@ax...>]

Hi,

As you know we are trying to use a kernel without TCPIP support. We =
succeed to make this kernel working with Decnet.
Now I'm trying to use lat. When I use lat on a native linux kernel =
(included TCPIP level) I succeed to use a lat port. However, when I try =
to use it with a kernel recompiled without TCPIP support, latd is =
correctly started but it does'nt work. After investigations, I notice =
that interface are not detected with this kernel.=20

When I show the status of the server with the latcp -d command which =
produces output something like this:
-----------------------------------------------------------------------
Node Name:  PC2                 LAT Protocol Version:       5.2
Node State: On                  LATD Version:               1.12
Node Ident: A Linux box

Service Responder : Disabled
Interfaces        : =20

Circuit Timer (msec):     80    Keepalive Timer (sec):     20
Retransmit Limit:         20
Multicast Timer (sec):    30

User Groups:     0
Service Groups:  0

Service Name   Status   Rating  Identification
PC2            Enabled    12 D =20

Port                    Node            Service         Remote Port     =
Queued
/dev/lat/lta101       	MPS_1F29CD                      PORT_1          =
Yes=20
-------------------------------------------------------------------------=


As you can see, no interface are reported. With the kernel included =
TPCPIP, We get :

-------------------------------------------------------------------------=

...
Service Responder : Disabled
Interfaces        : eth0=20

Circuit Timer (msec):     80    Keepalive Timer (sec):     20
...
-------------------------------------------------------------------------=


So I suppose that subroutines/functions used in interfaces.cc (or =
interfaces-linux.cc) needs to have TCPIP installed. Is there a way to =
make it working ? (modification of the interface detection function to =
do not used TCPIP functionnalities,  or which TCPIP module is necessary =
to compile in the kernel). It is strange that DECnet recognizes =
interfaces without TCPIP, but not LAT.


Thanks
