Ethereal-users: Re: [Ethereal-users] Ethereal 0.9.16 SSL & HPUX IPF runtime problem
Hello Guy Harris,
Thanks for your information. But I
have the run time problem in while executing the etherel & tehereal in HPUX
IPF platform.
Ethereal 0.9.14 works fine in HPUX IPF. But 0.9.16
has problem while loading plugins.
Ethereal 0.9.16 RUNTIME
Problem:

The only thing that
"--with-ssl" does is link with a crypto library
that comes with SSL
libraries; it does not affect Ethereal's ability to
dissect SSL (i.e., it
doesn't make the SSL dissector more capable).
It's a somewhat poorly
named option. It exists only to cause Ethereal
to be linked with
"-lcrypto" in order to make it work with some
versions of the UCD SNMP or
Net-SNMP libraries; Ethereal uses those
libraries only as helpers for
reading MIB files and using them to
improve the dissection of SNMP, but, as
those libraries are full SNMP
libraries, they include a lot of functionality
that Ethereal doesn't
use, and some of that functionality requires
encryption support, so, to
link with those versions of the SNMP library, you
have to link with
-lcrypto *even though Ethereal itself uses none of the
functions in
-lcrypto*.
I think it'd be great if we could make that
option not be necessary.
The configure script should see whether you
can link with the SNMP
library without "-lcrypto" and, if not, it should
automatically find
the crypto library (or let you specify where it is, with
a
"--with-lcrypto=" option) and arrange to link Ethereal with it, just as
it does for some *other* libraries that the SNMP library requires
("-lkstat" on Solaris, "-ldes425" on some versions of Red Hat
Linux).
