Haaalp.

I've got an Inova 500 controlled by a Sun Ultra 10 running Sol 7. I
recently "secured" that computer by installing OpenSSH w/wrappers (and the
7 or 8 other packages that need to be there) and putting hme0 behind a
Linksys NAT box, forwarding only port 22. In the process, instead of just
commenting out everything in inetd.conf, I disabled the script that starts
it, S72inetsvc.

You can't do that, I learned from Phil Louthan. The acquisition CPU needs
tftp in order to know who it is. So, I commented everything except in.tftpd
out of inetd.conf and started inetd.

Now setacq works and I can ping inova but not inovaauto. Trying to start
expproc results in complaints that the MSR board hasn't booted and, indeed,
it hasn't.

I started out thinking that my MSR board is bad. No problems until a power
failure Saturday, but then, the console hasn't been down since I redid my
Sun operating system. Is my problem hardware or my OS?
