Following are some common errors to watch out for:


It doesn't work together with Storable::fd_retrieve|fd_store, see
https://rt.cpan.org/Ticket/Display.html?id=23419.
You need to use freeze/nfreeze/thaw and syswrite/sysread the data
yourself. See the bug for examples how to do it.

---------------------

Note that a random number generator is required for the proper
operation of this module.  Systems that have /dev/random or
/dev/urandom are fine, but those that do not, like most versions
of Solaris, will need to fetch one before installing IO::Socket::SSL.
If you don't already have a favorite, try EGD (egd.sourceforge.net).

---------------------

Versions of perl-ldap below v0.26 do not work with this version
of IO::Socket::SSL because they contain a workaround for old
versions of IO::Socket::SSL that breaks new versions.

---------------------

One user mentioned that the following did not work as it should in
IO::Socket::SSL, but worked in IO::Socket::INET:

chomp($var = <$socket>);
print ord(chop($var));    # Prints "10" for people using ASCII

This is due to a bug in Perl that is fixed in 5.8.1.  If you need
a workaround, try one of the following:

chomp($var = $socket->getline());
chomp($var = scalar <$socket>);
chomp($var = $var = <$socket>);

Any function that returns the value of <$socket> (in scalar context)
unchanged will work.

---------------------

If you have 384-bit RSA keys you need to use Diffie Hellman Key Exchange.
See the parameter SSL_dh_file or SSL_dh for how to use it and
http://groups.google.de/group/mailing.openssl.users/msg/d60330cfa7a6034b
for an explanation why you need it.
