version ====== stunnel - 4.55 openssl - 1.0.1e

stunnel.conf ========== # Sample stunnel configuration file # Copyright by Michal Trojnara 2002 # Comment it out on Win32 #cert = /etc/tr69/stunnel.pem key = /etc/tr69/stunnel.pem # chroot = /usr/local/var/run/stunnel/ # PID is created inside chroot jail pid = /var/run/ssl.pid setuid = root setgid = root # Protocol version (all, SSLv2, SSLv3, TLSv1) sslVersion = TLSv1.2 # Workaround for Eudora bug #options = DONT_INSERT_EMPTY_FRAGMENTS # Authentication stuff verify = 1 # don't forget about c_rehash CApath # it is located inside chroot jail: #CApath = /certs # or simply use CAfile instead: #CAfile = /usr/local/etc/stunnel/certs.pem #CAfile = /etc/tr69/ca.crt # CRL path or file (inside chroot jail): #CRLpath = /crls # or simply use CAfile instead: #CRLfile = /usr/local/etc/stunnel/crls.pem # Some debugging stuff debug = 7 output = /var/log/ssl.log foreground = yes # Use it for client mode client = yes # Service-level configuration [https] CAfile = /flash/Cert.pem accept = 127.0.0.1:8001 connect = acs.qacafe.com:80 #accept = 8080
