Hello Netland,
I'm new to this newsgroup, so please excuse me if the problems I have were
discussed previously. I've just installed AIX v2.2.1 on our RT's. I also
use NFS/AIX to integrate them with the other UN*X machines at our department.
Unfortunately there are some problems I have encountered. If you know of a
solution, please e-mail it to me (I'll summarize to the net)
Problem 1: /etc/group problem
-----------------------------
At our site, we use the yellow pages to store password and group membership
information. It appears that group membership is limited to a maximum of
8 groups on AIX. Rlogins from e.g. a VAX running Mt.Xinu 4.3BSD fail if you
are registered in more than 8 groups.
Is this a bug or a feature ? Are there ways to fix this problem ?
Problem 2: biod problem
-----------------------
The "Managing the AIX OS" manual suggests to start a number (default 4)
of "biod" daemons. When I did this, the following occurred:
- run a compile, and store the executable on a remote filesystem
- try to execute the a.out ==> gives a memory fault
When I remove the "biod" daemons, the problem disappears. What's happening
here? Seems to me that there is something wrong with the caching algorithm.
Problem 3: gateway problem
--------------------------
One of the RT's functions as a gateway between Ethernet and Token-Ring.
I run the routing daemon "routed" to broadcast availability of the Token-Ring
to networks attached to the Ethernet. Works fine initially, but after a few
minutes the Token-Ring is no longer reachable!!! (strange! because it's
attached to my own machine). Running "routed -t" with tracing enabled, shows
that broadcasts on the Token-Ring are also received by the machine performing
the broadcast. If my interpretation is correct, a routing loop occurs: the
RT thinks there is a shorter route to the Token-Ring, namely through itself,
and it increases the hop-count. At hop-count 16, the token-Ring disappears.
Is this a bug or a feature? What can I do to set up my RT as a gateway
between ethernet and Token-ring ???
