Wiring umass unit numbers

I have a USB floppy drive and a USB flash card reader/writer.  At
various times, neither, one, or both devices are plugged into the
computer.  Depending upon when each is plugged in, the floppy
drive might become /dev/da0 and the flash reader/writer /dev/da1,
or vice versa.  Is there a way to specify which should be which?

sendmail


Hope it's ok to ask a sendmail question here, I've exhausted the news
groups and web....

I'm running sendmail 8.12 and it seems to have a "MAIL FROM" test in it
somewhere. Mail "FROM" is not an effective spam defense and I have it
locked down otherwise, so I want to shut off the "MAIL FROM" test in
sendmail. I have a client who sends out email alerts using the server
and uses a random invalid return address for each alert. Sendmail is
rejecting the messages based on the From field. I have their server's IP
address in the relay-domains file, but it's ignoring that and rejecting
the mail anyway.

I've tried adding the address to the virtusertable db, aliases, and the
access db as "RELAY" as "name+*" ,  and sendmail still rejects the messages.

ANY ideas will be appreciated.....

Every little bit helps.

Have you tried:
FEATURE(`accept_unresolvable_domains')

Re: sendmail


The domain is resolvable. It's a local domain, that's why the server
rejects the message. It can see that the username doesn't exist and
dumps the connection right away. Here's an example, the mail never gets
sent. "woohoo.com" is the local domain:

AFAIK, no, but if you just need to have constant device names, you
can use labels provided by glabel(8), e.g. if you issue
# glabel label -v MYFLASH /dev/da0 when da0 is flash, you'll
always have /dev/label/MYFLASH entry whenever you flash is
plugged.

Unfortunately, this technique can't be used with floppy, for
glabel information is stored on the media itself, that is you
need to label every floppy separately.

Hope that helps.

I can't reproduce this with sendmail 8.13 (though I'm not sure I'm
correctly replicating your environment).  I suggest you either UTSL or
ask on a sendmail list.

Re: sendmail


I moved them to another server where "wohoo.com" isn't set up and it's 
working fine. But I need to figure out why sendmail HAS to check the 
local server and shut that part off. It's an "issue".
