Hello, Marshall!

On Wed, 27 Aug 2003 09:44:26 -0700, you said:

This version works at least on e.jabber.ru, on jabber.ttn.ru as IRC gateway,
and on my machine (of course :).  I'm sure this problem because of
crypto_drv.so

 MR> seem like this stuff ought to work, but the ssl problem is clearly some
 MR> kind of a syntax error in the code...

This backtrace from ejabberd.log:

** Reason for termination = 
** {badarg,[{erlang,port_control,
                    [#Port<0.239>,1,"mrose:miz-mishtal.dbc.mtview.ca.us:test"]},
            {crypto,control,2},
            {cyrsasl_digest,response,5},
            {cyrsasl_digest,mech_step,2},
            {cyrsasl,server_step,2},
            {ejabberd_c2s,wait_for_sasl_response,2},
            {gen_fsm,handle_msg,7},
            {proc_lib,init_p,5}]}

means that process failed in call to crypto_drv.so (calculating md5 hash from
string "mrose:miz-mishtal.dbc.mtview.ca.us:test") in calculating of response
for DIGEST-MD5 algorithm.

Try to do this:

% erl
Erlang (BEAM) emulator version 5.1 [source]

Eshell V5.1  (abort with ^G)
1> crypto:start().
ok
2> crypto:md5("abc").
<<144,1,80,152,60,210,79,176,214,150,63,125,40,225,127,114>>

If you will get error, then check if crypto_drv.so compiles fine.  Below are
some messages from erlang-questions mailing list that may help.

Hopefully the patch from Jimmy Olgeni <olgeni at uli.it> included below
will correct this problem,

Building with OpenSSL 0.9.7 requires this patch:

Patch is for FreeBSD 4.8 and is below. Big thanks to Alexander Timoshenko.

Good day,

Try to discover $ERL_TOP/lib/crypto-*.*.*/priv/lib/elibcrypto.so:

1. nm -a elibcrypto.so | grep des_set_key

Output must be something like:

00004b80 T des_set_key

2. Look that it can find all libraries it wants:

ldd elibcrypto.so

3. If you installed Erlang from ports try to recompile driver manually
using patch from

http://www.erlang.org/ml-archive/erlang-questions/200303/msg00439.html


Best Regards,
Vladimir Sekissov
