Stunnel failover
by Ray 16 Sep '20

16 Sep '20

Stunnel's failover option with prio settings works fine but the application first tries 3 syn to connect to the first endpoint and if failed then it tries the second endpoint. Is there any way to configure stunnel to try only once and failover to the second connection endpoint?

using Android Keystore with stunnel
by blacksun＠directbox.com 09 Sep '20

Hello, i am using stunnel 5.56 on Android 7.0. It is a non-rooted device. Android stores keys and certs in the android keystore. I am using a Let's Encrypt Cert on serverside, and on clients the options veryChain and chechHost. How can i use the System-integrated CA-Certs of Android for verifying the server-cert issued by Let's Encrypt? When i am searching the net, there are infos saying that the certs and keys are not accessible by filestructure, but there would be apis to access the keystore. The keystore would be protected with the PIN of the device. Thanks.

Hi James.To the best of my knowledge, your options include Darwin firewall and HAProxy - geoip. >>Just wondering if there is a way to have Stunnel not accept connection from certain IPs? stunnel -version stunnel 5.56 on x86_64-apple-darwin18.7.0 platform Threading:PTHREAD Sockets:POLL,IPv6 TLS:ENGINE,FIPS,OCSP,PSK,SNI
