[stunnel-users] Slow connection to remote stunnel

Tue May 31 16:52:40 CEST 2011

Hi Thorsten,

I guess it's due to a bug (by design, of course) in Microsoft
implementation of SSL.
Add:
    TIMEOUTclose = 0 
to your stunnel.conf and restart stunnel.

Less likely this could be due to DNS checks in your /etc/hosts.allow
and/or /etc/hosts.deny.
Disable libwrap support with:
    libwrap = no

Mike
