Upgrade issue - hash problems

According to my copy of _Sendmail_3rd_Edition_ by Bryan Costales (ISBN 1-56592-839-3), on page 888 (S23.7.7), the hash database map is only available if sendmail is compiled with NEWDB defined and the Berkeley or Sleepycat db(3) library linked.

So, go to http://www.sleepycat.com/download/db/index.shtml and download the database, compile and install it.

Then, when you rebuild sendmail, in the ./devtools/Site/site.config.m4 file, put:

APPENDDEF(`confLIBDIRS', `-L/path/to/BerkeleyDB/lib')
APPENDDEF(`confINCDIRS', `-I/path/to/BerkeleyDB/include')
APPENDDEF(`confENVDEF', `-DNEWDB')

Sendmail will be rebuilt with the appropriate support.

I have just spent 2 hours fighting this... I must have the Berkley DB as existing sendmail uses it, and I built the access.db using makemap ages ago.

Also, sendmail info states that if 'libdb.so' exists, it will build NEWDB anyway.

I have:

/usr/lib/libdb.so.2 -> libdb1.so.2
/usr/lib/libdb.so -> /usr/lib/libdb2.so.3

If I build with the in /devtools/Site/site.config.m4 I get:

defines../../include/sm/bdb.h:17:17: db.h: No such file or directory

I tried hooking a symlink libdb.so to point to either of those files, but same build error arises.

So it looks like I am missing headers.

I am not sure to update and install berkley DB, as it could break my existing sendmail.

...and I thought configuring sendmail to work was hard... heh.

OK, lets change the tact on this question.  I am a home user, using sendmail just to receive and send mail from my hosted domain here.  Do I need to use DB's at all?

Typo:

/usr/lib/libdb.so -> /usr/lib/libdb2.so.3

should have been:
/usr/lib/libdb.so.3 -> libdb2.so.3

I cut and paste wrong line in scroll.

Hash is only used in table lookups, like the "virtusertable" and "access" etc - you probably don't need it, but I suspect something somewhere will need to be fixed if you try to run without it.

Perhaps you're building wrongly?  Here's how you should be doing it:-

cd /usr/src/redhat/SPECS/
rpmbuild -bc sendmail.spec

Why do you need 8.13.1 ?  Maybe something else will work too?

--> Chris, I haven't got Redhat source - as I said, Redhat stopped free up2date ages ago - I am using sendmail 8.13.1 source.


OK, I managed to get a berkley db_deveL RPM to the db installed.  That then allowed berkley* db to build correctly.

A bit of faffing about with sendmail.mc to get it all to work, and all OK.

After this, I just upgraded an old server at work... running Linux 2.2.26 - I got through sendmail install in about 10 minutes now I know what to do/what gotcha's on the way.

Thanks,

Nick
Great word Berk... Cockney Rhyming slang -> Berkley Hunt...

Nick,

I appreciate you accepting my answer, but I don't understand the rather low grade of C. What did I do wrong?

Nothing, really, but I marked lowest grade as I guessed DB headers were missing (the problem), and also as I read and stated here sendmail auto-builds -NEWDB if it finds libdb.so - which it did.

So you confirmed what I found out and learnt before your initial comment.

No offence meant ;).

C == average BTW, not poor.  I also thought my 500 points was a bit high for this type of question too, so it's swings and roundabouts.

Nick

If you solved the issue on your own, then it would have been better to post a (free) Question in the Community Support TA (https://www.experts-exchange.com/Community_Support/) and request that this Question be PAQed and your points refunded. A grade of C means that I didn't do a good job of providing an answer. You can still make that request (be sure to include a link to this Question).

No, I will not do that.  Your help is very much appreciated, and two heads are better than one - it's nice to have a conference.

I am bound to have further questions, so I will repay :)

Grade C == you answered the question!  You didn't do a 'bad job' (leave the politicians to do that) - at the time I thought because with a 'little' help I sussed it, you maybe shouldn't get a 'good' or 'great' mark - all grades are winners in my eyes?

I have no qualms about 'modding up' so to speak - can that be done?

Nick

I appreciate your feedback.

If you'd like to change the grade (which does NOT affect the amount of points you spend), then post a Question in the Community Support TA (as described above) and request a Grade Change. A moderator can do it for you (or re-open the Question and let you grade it again).

I have already mailed a mod... you will get a B soon :)

Nick
P.S. get ready for my next question (a work question - not a home question)... it's a stinker! ;)

The grade has been changed as requested.
