Bilbo is the teststand computer. There is another one as well, but bilbo is the main one that we use.

If it can be pinged, then you should be able to use the vme program (I don’t know who wrote it) to communicate between boards on the crate.

Here is an example. A TDC board is in slot 16. Issue the following command to read from memory:

vme bilbo read 16 0

The output of this command should be deadbe00.

You can also write (and turn on a light on the front panel) with:

vme bilbo write 3c 1

Since MaxPlusII is no longer maintained, we need to use Quartus to program our chips. We have some very old MaxPlusII files that we need to recompile (after making changes) and then use to program some chips.

Some notes on the process:

-File -> Convert Programming Files is where you create a single .pof file from our collection of .sof files.

Then just use the programmer to put it on the chip.

For example,

[root@tester openldap]$ slappasswd -s test
{SSHA}Nq5hUWWzoq0WUEqnMAx/9YhmmSgMJbnQ

I can then use that SSHA line in my ldif file.

In preparing for our mail server upgrade, I’m setting up a new test server, just to make sure that everything will be working together as I hope it will. I had a problem with sendmail in that I was able to receive mail ok, but was unable to send it. In the mail logs, I got messages like this:

Sep 17 08:47:03 server sendmail[2884]: l8HDkmas002884: yo.robot.com [192.168.52.8]: possible SMTP attack: command=AUTH, count=3

Since yo.robot.com is my computer, I knew we weren’t getting hacked. The problem was that I didn’t have saslauthd running on the mail server. As soon as I turned it on, things were working fine.
