Hello All,
I'm trying to configure STunnel4 on Windows to connect to my VPS installed with STunnel, so I can use SSH through a DPI laden network.
The configuration works if I try at home, or on a mobile data hotspot, but if I attempt within the DPI network, it does not work, and provides this console output:
2018.03.22 09:30:15 LOG5[main]: stunnel 5.44 on x86-pc-msvc-1500 platform 2018.03.22 09:30:15 LOG5[main]: Compiled/running with OpenSSL 1.0.2m-fips 2 Nov 2017 2018.03.22 09:30:15 LOG5[main]: Threading:WIN32 Sockets:SELECT,IPv6 TLS:ENGINE,FIPS,OCSP,PSK,SNI 2018.03.22 09:30:15 LOG5[main]: Reading configuration from file stunnel.conf 2018.03.22 09:30:15 LOG5[main]: UTF-8 byte order mark detected 2018.03.22 09:30:15 LOG5[main]: FIPS mode disabled 2018.03.22 09:30:15 LOG5[main]: Configuration successful 2018.03.22 09:30:24 LOG5[0]: Service [ssh] accepted connection from 127.0.0.1:65086 2018.03.22 09:30:24 LOG5[0]: s_connect: connected 130.185.251.28:443 2018.03.22 09:30:24 LOG5[0]: Service [ssh] connected remote server from 172.28.1.25:65087 2018.03.22 09:30:25 LOG4[0]: CERT: Certificate not found in local repository 2018.03.22 09:30:25 LOG4[0]: Rejected by CERT at depth=0: CN=130.185.251.28 2018.03.22 09:30:25 LOG3[0]: SSL_connect: 14090086: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed 2018.03.22 09:30:25 LOG5[0]: Connection reset: 0 byte(s) sent to TLS, 0 byte(s) sent to socket
This is the configuration I'm using:
[ssh] client = yes accept = 443 connect = 130.185.251.28:443 CAfile = peer-ssh.pem verifyPeer = yes
The odd thing, is that if I connect using my mobile data, and then switch over to filtered internet and try again, it works fine, and adds the following lines to the log:
2018.03.22 09:36:46 LOG5[1]: Service [ssh] accepted connection from 127.0.0.1:65237 2018.03.22 09:36:46 LOG5[1]: s_connect: connected 130.185.251.28:443 2018.03.22 09:36:46 LOG5[1]: Service [ssh] connected remote server from 192.168.43.115:65238 2018.03.22 09:36:46 LOG5[1]: Certificate accepted at depth=0: C=GB, ST=Lincolnshire, L=Horncastle, O=N/A, OU=N/A, CN=personal.kilosierracharlie.me, [email protected]
Has anyone got any ideas regarding this issue? It's not mission critical, but it's quite annoyingly repetitive!
Cheers,
Kieran.
