pls excuse the length of this email : i am hoping that by
including all details, someone can put me out of my misery
and i can eventually go home :
The goal :
--------
I am trying to run virtual domains on my laptop connected to
the Internet with 3com pcmcia ethernet card (zp0).
The laptop boots as word.com.my (202.184.153.84) with no problems
and now i simply wish to ifconfig alias models.com.my (202.184.153.18) too...
This is pretty simple on AIX and OSF with
# ifconfig zp0 202.184.153.18 netmask 255.255.255.0 alias
The problem :
-------------
# ifconfig zp0 202.184.153.18 netmask 255.255.255.0 alias
caused and error ....
ifconfig: ioctl (SIOCAIFADDR) : file exists
and i found archive references saying to use the following :
# ifconfig zp0 202.184.153.18 netmask 255.255.255.255 alias
but then i received -
#Feb 22 05:32:16 word routed[50]:punt RTM_ADD without a gateway
Feb 22 05:32:16 word routed[50]:punt RTM_ADD without a gateway
Feb 22 05:32:16 word routed[50]:punt RTM_ADD without a gateway
#Feb 22 05:32:16 word routed[50]:possible netmask problem between
zp0:202.184.153.18/32 and zp0:202.184.153.0/24
Feb 22 05:32:16 word routed[50]:possible netmask problem between
zp0:202.184.153.18/32 and zp0:202.184.153.0/24
Feb 22 05:32:16 word routed[50]:possible netmask problem between
zp0:202.184.153.18/32 and zp0:202.184.153.0/24
#Feb 22 05:32:16 word /kernel:arp_rtrequest:bad gateway value
I can ping both word.com.my and models.com.my from any other
machine. But if I ping them from the FreeBSD box itself, I can
ping the original interface IP (word.com.my) but pinging
the alias, models.com.my, gives :
Feb 22 05:32:16 word /kernel arpresolve:can't allocate llinfo for
202.184.153.18
I checked the archives and it would appear that
arpresolve errors are due to the routing tables being
not set up properly.
The Evidence :

additional info :
-----------------
running secondary name server on this FreeBSD box.
BUT the zone files equating models.com.my to 202.184.153.18 are
on the Domain Name server one up from us in the food chain.
(202.184.153.1 is our router)
ie. named.root contains ...
. 3600000 IN NS duke.neuronet.com.my.
duke.neuronet.com.my. 3600000 A 202.184.153.3
=== localhost.rev : ===
; This file is automatically edited by the `make-localhost' script in
; the /etc/namedb directory.
;
@ IN SOA world.com.my. root.word.com.my. (
970221 ; Serial
3600 ; Refresh
300 ; Retry
3600000 ; Expire
3600 ) ; Minimum
IN NS word.com.my.
1 IN PTR localhost.com.my.
=== /etc/resolv.conf ===
nameserver 202.184.153.3
domain neuronet.com.my
Can anyone pls point me in the right direction here?
Evi Nemeth's normally very helpful book is confusing me with routing and
"route" .
if you could email me at sweeting@tm.net.my, i would be extremely grateful.
thank you very much in advance.,
