two stunnels in the local network
by alessandro.deliperi＠ichnobyte.it 02 Nov '23

02 Nov '23

Hi everyone, this is my first question. I have successfully configured a stunnel (A) that does the job of it. I need to configure a second stunnel (B) that works in a more hidden network. When B connects to A, which connects to public mail server X I get a time out error. I bring you the logs, I think it is related to the fact that both stunnel servers are trying to establish a TLS session. Is there a way to solve? 2023.11.02 08:42:10 LOG7[0]: Option TCP_NODELAY set on local socket 2023.11.02 08:42:10 LOG5[0]: Service [smtp-tls] accepted connection from 192.168.0.109:46078 2023.11.02 08:42:10 LOG6[0]: s_connect: connecting 192.168.180.10:25 2023.11.02 08:42:10 LOG7[0]: s_connect: s_poll_wait 192.168.180.10:25: waiting 10 seconds 2023.11.02 08:42:10 LOG7[0]: FD=6 events=0x2001 revents=0x0 2023.11.02 08:42:10 LOG7[0]: FD=11 events=0x2005 revents=0x0 2023.11.02 08:42:10 LOG5[0]: s_connect: connected 192.168.180.10:25 2023.11.02 08:42:10 LOG5[0]: Service [smtp-tls] connected remote server from 192.168.0.23:41156 2023.11.02 08:42:10 LOG7[0]: Setting remote socket options (FD=11) 2023.11.02 08:42:10 LOG7[0]: Option TCP_NODELAY set on remote socket 2023.11.02 08:42:10 LOG7[0]: Remote descriptor (FD=11) initialized 2023.11.02 08:42:10 LOG7[0]: <- 220 mailservers 2023.11.02 08:42:10 LOG7[0]: -> 220 mailservers 2023.11.02 08:42:10 LOG7[0]: -> EHLO localhost 2023.11.02 08:42:11 LOG7[0]: <- 250-email-smtp.posta 2023.11.02 08:42:11 LOG7[0]: <- 250-8BITMIME 2023.11.02 08:42:11 LOG7[0]: <- 250-STARTTLS 2023.11.02 08:42:11 LOG7[0]: <- 250-AUTH PLAIN LOGIN 2023.11.02 08:42:11 LOG7[0]: <- 250 Ok 2023.11.02 08:42:11 LOG7[0]: -> STARTTLS 2023.11.02 08:42:11 LOG7[0]: <- 503 TLS not available due to temporary reason: TLS already active 2023.11.02 08:42:11 LOG3[0]: Remote server is not RFC 2487 compliant 2023.11.02 08:42:11 LOG5[0]: Connection reset: 0 byte(s) sent to TLS, 0 byte(s) sent to socket

Suppressing warnings
by Ian Pilcher 31 Oct '23

31 Oct '23

I am using stunnel (along with an Apache reverse proxy) to enable my browser to connect to my old managed switches. An example configuration looks like this: debug = warning syslog = yes [switch1] client = yes accept = 127.0.0.1:8081 connect = 192.168.4.1:443 verifyChain = yes checkHost = switch1.example.com CAfile = /etc/pki/ca-trust/source/anchors/example-com-ca.crt sslVersion = TLSv1 ciphers = DHE-RSA-AES256-SHA options = ALLOW_UNSAFE_LEGACY_RENEGOTIATION securityLevel = 1 OCSPrequire = no Everything is working, but I'm seeing a lot of warnings in my system log: OCSP: No OCSP stapling response received transfer: s_poll_wait: TIMEOUTclose exceeded: closing Are there any settings that I can use to suppress these warnings? Thanks! -- ======================================================================== If your user interface is intuitive in retrospect ... it isn't intuitive ========================================================================

TLSV1.0
by Stefano Pelli 27 Oct '23

27 Oct '23

Dear all, as my first post, I am asking a confirmation: is TLS ver 1.0 still supported by stunnel (unfortunately, I need that deprecated version to access a server)? It all worked fine, then I upgraded to Kubuntu 22.04 and for some reason that broke the support of this protocol. I get the connection closed right after trying to open it. Before upgrading all was working without a hitch. Since then (1 year ago), I have been looking for solutions and trying all sorts of fixes by changing stunnel.conf, but with no success. Can you be so kind to give me some info about this and if possible a remedy until the server gets updated (not under my control)? Thank you in advance, Stefano

Following advice founf in the net, I had already included: >[system_default_sect] >CipherString = DEFAULT@SECLEVEL=1 in openssl.cnf But still it would not work through stunnel. Today I tried a connection directly from openssl and I managed to succesfully initiate and conclude a proper POP3 dialog with the culprit server. Then, looking at the messages from openssl, I saw that the connection was established, as expected, by TLSV1 and AES256-SHA protocol. Therefore, I tried to force this in the relevant section of stunnel.conf: >ciphers = AES256-SHA But with the same result when trying to open the connection through stunnel (5.71) >telnet 127.0.1.1 110 >Trying 127.0.1.1... >Connected to 127.0.1.1. >Escape character is '^]'. >Connection closed by foreign host. With the other servers I can this way estblish a POP3 dialog, as I managed directly through openssl. What am I missing here? Thank you for any addition insights! Stefano

But that is not installing the application silently. Could you please help us to install the application silently.

Stunnel is not a VPN, so no it can't "hide your browsing". Hiding your browsing needs more than just stunnel because of how DNS and other components for browsing work. Question 2 is beyond the scope of stunnel's list to answer. This said: If you have to ask how to hide your browsing that means you're violating your network's use policies, and with Fortinet and Fortigate in line it sounds like you're on a workplace network. Just don't use your workplace network for whatever shady stuff you're concerned about them finding you doing.
