Subject: SGI, CAP, and aufs: It USED to work!

Help!

We are running CAP 6.0 pl126 on our SGI personal irises (30TG).
Since the SGIs won't run the ethertalk version (as far as I know), 
we are using the IPTalk numbers and the /etc/atalk.local file. 
Everything was running fine up to about 3 weeks ago when I went out of 
town (around Oct16). When I returned, on Nov2, I find that the aufs server 
running on the SGI is not working properly (eg I don't see it via the Macs 
Chooser). lpr works fine to print from the SGI to the Laserwriter 
on our AppleTalk zone. I don't see the IPGATEWAY, snitch, nor the aufs server
entries supposedly mounted from the SGI using atlook. Atistest says okay 
and atis dump shows the aufs server, snitch entry, and atis test:testing@*
entries, but I don't see them via atlook!

I was told by networking services that the FastPath
boxes were altered so that the subnet mask is now 255.255.255.0 instead of
0.0.0.0. They suggested that I check the subnet mask of our Irises, but
it seems to be okay: 

proton# ifconfig ec0
ec0: flags=c63<UP,BROADCAST,NOTRAILERS,RUNNING,FILTMULTI,MULTICAST>
        inet 128.101.80.2 netmask 0xffffff00 broadcast 128.101.80.0

They asked me to check the netstat, which I did:

proton% netstat -n -r
Routing tables
Destination      Gateway            Flags    MTU    RTT RTTvar    Use Interface
127.0.0.1        127.0.0.1          UH         0      0      0  20609  lo0
128.101.80.2     127.0.0.1          UH         0      0      0    542  lo0
default          128.101.80.254     UG         0      0      0 505677  ec0
128.101.80       128.101.80.2       U          0  0.438  0.375 468396  ec0

They said this was wrong, and told me to route delete 128.101.80.1 127.0.0.1
which I did and now get the following with netstat:

proton# netstat -n -r
Routing tables
Destination      Gateway            Flags    MTU    RTT RTTvar    Use Interface
127.0.0.1        127.0.0.1          UH         0      0      0  22948  lo0
default          128.101.80.254     UG         0      0      0 591322  ec0
128.101.80       128.101.80.2       U          0  0.438  0.375 568181  ec0

None of this helped!

The following are the files I am using as well output from atlook, atistest,
and atis dump (probabably more than you want to know):

I should see these three entries when I run atlook from proton,
the first one created by snitch, the second by aufs, and the last by atistest.

I don't see any of them Biomed Eng Ctr.

Can somebody give me a clue?
