Thanks to everybody with the help they gave me figuring out the
IPTalk addressing issues. I'm still getting nowhere, however, making CAP
work. I've got my FP-4 set up to download atalkatab via tftp, which it
seems to be doing fine (I can watch the diagnostic packets in FastPath
Manager). My atalkatab and atalk.local files look like:
----------------
55.1 N2 128.122.136.160 "NYU Ether" #Campus IPTalk
0.1 E 128.122.136.160 "NYU Ether" #Campus EtherTalk
4.10 KC 128.122.136.160 "NYU PHRI" #PHRI LocalTalk
I128.122.0.0 I128.122.136.1 # ipbroad, ipname
I128.122.136.1 L0 # ipdebug, ipfile
L0 L0 L0 L0 S0.1 S200 # other, ethertalk, ddp range
LX0 S2 S6 # flags, ipstatic, ipdynamic
S4.10 S55.1 # localtalk, iptalk
----------------
# mynet mynode myzone
55.1 1 "NYU Ether"
# bridgenet bridgenode bridgeIP
55.1 160 128.122.136.160
# nisnet nisnode
55.1 1
----------------
Can anybody see anything wrong with them? The problem is that when
I start up atis and then run atistest, I get:
# atis

nbp register error because: couldn't register name - is atis running?
For each of the nbp_timeout lines above, I can see a single packet
go out from wombat (the host I'm running atis/atistest on) to the kbox
using tcpdump:
% tcpdump proto udp and '(' port 201 or port 202 or port 203 or port 204 or port 205 or port 206 or port 207 or port 208 ')'

15:30:08.02 wombat.phri.nyu.edu.16516 > 128.122.136.160.at-nbp: udp 43
I'm totally at a loss at this point to figure out what's going on.
One thing I don't understand is why the nbp packets get sent to the kbox at
all; since atis and atistest are running on the same host, why does the
gateway even get into the act? What's even more bothersome, is that I had
atis/atistest working a couple of days ago, and I figure out what I did to
change things!

If this is right the address given might need to be "128.122.136.0" as well. > I128.122.0.0 I128.122.136.1 # ipbroad, ipname ^^^^^^^^^^^^ ^^^^^^^ This says the IP broadcast address is 128.122.0.0. They must both be the same, and more importantly, must match what your CAP host itself believes to be the correct broadcast address. Is your broadcast address all-ones or all-zeroes? Is your Class B network subnetted or not? If it is a Sun, "ifconfig" is the command to find out. ======================== Tom Evans tom@wcc.oz.au ** ADD ".au" MANUALLY (don't trust "reply") ** Webster Computer Corp P/L, 1270 Ferntree Gully Rd Scoresby, Melbourne 3179 Victoria, Australia 61-3-764-1100 FAX ...764-1179 A.C.N. 004 818 455
