Fwd: Stunnel Performance strangeness
by Scott McKeown 10 Mar '17

Hi All, We have been doing some throughput testing and are wondering of you can help explain some of the results we have been getting. We are trying to establish the maximum number of handshakes per second our appliances can do when using Stunnel. Our tests have been done on a 4 core Intel(R) Xeon(R) CPU E3-1230 v5 @ 3.40GHz machine with 8Gb ram. Using stunnel 5.33 openssl 1.0.2j (We use stunnel 5.33 here, but this was also tested with stunnel 5.40 and we got the same issue) Stunnel was compiled with - ./configure --enable-fips --enable-ipv6 --with-threads=pthread --sysconfdir=/etc --with-ssl=/usr/src/built/OpenSSL_1_0_2j-no_march/usr/local/ --disable-libwrap --disable-systemd I was using a python script of my own design for load testing when I noticed the problem we then switched to an open source package called vegeta https://github.com/tsenart/vegeta the command I was using to run it was - echo "GET https://10.10.10.10:443" | ./vegeta attack -workers=30 -rate=3000 -duration=300s -insecure > test.out We are essentially seeing a degradation in throughput at a fixed point in time. I am seeing the problem when using 3000 transactions per second. We are doing https gets through stunnel to a http backend, 1 transaction is an ssl handshake the http get and waiting for the response. Interestingly if I try 5.06 it works fine I get a smooth constant loading. Please take a look at 30worker3000rate5.33-300s.png where you can see after about 55 seconds there is a jump in latency. I get the same issue if I run the test with 2000 transactions. Please see 30worker20005.33-700s.png but with the lower transaction rate the issue takes longer to rear its head. The issue doesnt happen if I run the test with 3000 transaction using 5.06. Please see 30worker3000rate5.06-300s.png >From looking at the graphs our thoughts were that we were hitting some sort of cache limit and used that as a starting point. We have taken a look at the code changes between versions we know were working and the problematic version and the main thing that stands out is the changes to the leak detection. Previously this was partially based on the number of clients but has been changed to use the sections. This led to the decision to try a different limit value and found the number of connections we saw before seeing an issue corresponds to the change of the limit value. We think we have identified the code that is causing the problem/doing something funny it was added in 5.33 NOEXPORT long leak_threshold() { long limit; limit=10000*((int)number_of_sections+1); #ifndef USE_FORK limit+=100*num_clients; #endif return limit; } its src/str.c when increasing the limit number so limit=10000*((int)number_of_sections+1) to limit=20000*((int)number_of_sections+1) This still results in an increase in response time but at a later time in the test, please see 30worker3000rate5.33-ben-highlimit.png Interestingly once I end up in this state I am stuck with high latencies until I restart stunnel. (The box I am testing on was left over night to make sure its not any hanging tcp connections or anything like that) I must admit we are at the limit of our C understanding and your imput would be welcomed. -- With Kind Regards.

Segfault after connecting
by Andrew Culver 23 Feb '17

23 Feb '17

I had my stunnel instance working as expected last week. Since then I've moved the server behind a load balancer, which is doing regular health checks (opens a tcp connection, then disconnects) to see that stunnel is up. I don't believe the health checks are a problem, but they're the only change I've made since I had stunnel working. I can see the health checks connecting and disconnecting. However when I open a new connection, either by telnet or by: openssl s_client -connect mtar.uwo.ca:587 -starttls smtp ... stunnel says it fails to verify the server certificate, then seg faults. I'm running stunnel 5.40 and I'm having the same problem on 2 different servers running openssl 1.1.0d and 1.1.0e. Here's my config: [root@mtar1 stunnel]# egrep -v '^;|^ *$' stunnel.conf ; Sample stunnel configuration file for Unix by Michal Trojnara 2002-2017 setuid = stunnel setgid = stunnel pid = /usr/local/var/run/stunnel/stunnel.pid foreground = yes debug = debug [uwo2local] accept = 587 cert = /usr/local/etc/stunnel/mtar-withprivatekey.pem connect = 20587 protocol = smtp [local2o365] client = yes accept = 127.0.0.1:20587 connect = smtp.office365.com:587 checkHost = smtp.office365.com verifyChain = yes CApath = /etc/ssl/certs OCSPaia = yes protocol = smtp Here's my debug log: The health checks are from 172.18.58.5 and my test connection which leads to the seg fault is from 129.100.6.17.

stunnel on Windows Client: Changing active network interface (wired, wireless)
by b.koch.kemper 17 Feb '17

17 Feb '17

Dear stunnel community, we are running an application on our windows clients. The application needs a remote connection to our server (linux) for remote function calls. We could successfully secure this connection via stunnel. However, when our windows users change their network connection (e.g. they disconnect their notebook from the docking station to our corporate wifi) the connection and hence the whole application breaks. The users actually have to restart stunnel to make the application work again, which is really inconvenient. As the application on the notebook is always using the same port, is it somehow possible to make stunnel establish a new connection using the new active network interface? Kind regards, Bernhard

RSA too big problem
by Vikrant Agarwal 16 Feb '17

16 Feb '17

Hi, I upgraded my Stunnel server machine to CentOS 6.8 and post upgrade , the stunnel too got upgraded to stunnel 4.29 on x86_64-redhat-linux-gnu with OpenSSL 1.0.1e-fips 11 Feb 2013 . Now since then many of the stunnel client using newer stunnel client (those uses TLSv1.2 for Negotiation) are not able to connect . I get below error on the server in logs RSA_sign:digest too big for rsa key:rsa_sign’ How to fix this please? Regards, Vikrant

Re: [stunnel-users] Problem with 5.40 and Peer suddenly disconnected
by Brian McGinity 08 Feb '17

08 Feb '17

I found the archives and downgraded to 5.37 and this fixed the problem. Before going this route I tried 5.40 and 5.41 beta and both had the same issues with 'Peer suddenly disconnected'. Strange that it this was only happening for one particular connection (1 out of 7). It would happen with every test. If you would like for me to beta test another version, I would be happy to try.

Problem with 5.40 and Peer suddenly disconnected
by Brian McGinity 07 Feb '17

07 Feb '17

After updating to stunnel 5.40 on x86-pc-msvc-1500 platform, I am getting a Peer suddenly disconnected each time I post data to a particular url. [VISION_WEB] client = yes accept = 127.0.0.1:1935 connect = xx.xx.web.com:443 sslVersion = TLSv1 2017.02.07 16:30:08 LOG5[160]: Service [XX_WEB] accepted connection from 192.168.100.21:53507 2017.02.07 16:30:08 LOG5[160]: s_connect: connected 11.11.111.36:443 2017.02.07 16:30:08 LOG5[160]: Service [XX_WEB] connected remote server from 192.168.100.21:53508 2017.02.07 16:30:08 LOG3[160]: SSL_connect: Peer suddenly disconnected 2017.02.07 16:30:08 LOG5[160]: Connection reset: 0 byte(s) sent to TLS, 0 byte(s) sent to socket This is a production issue and is causing a lot of problems for a lot of people and I need to do something quickly. Is it possible to download stunnel 5.37 installed to see if going back to this version will fix this issue? Where is it? Or does anyone possibly know why this might be happening? Thank you for your help. Brian

Default passthrough to different destination?
by Mark Boyce 03 Feb '17

03 Feb '17

Hi All Wondering if there’s a way to pass an unencrypted connections traffic to an alternative location if a client does not SSL/TLS with the stunnel server? So considering stunnel running as a server to wrap an unencrypted SMTP server. If the SMTP client/server talks SSL/TLS all is good and as expected. If the client tries to talk without encryption it gets disconnect. Is there any way to send this traffic elsewhere rather than disconnecting the client? So that stunnel is adding an SSL/TLS option to a service rather than enforcing it. Splitting the traffic to destination servers based on if the client was encrypted or not. Thoughts? Thanks Mark

Mixed cert/PSKsecrets & TLS/SSL before proxy
by Varda Zklir 02 Feb '17

02 Feb '17

Hello Gentlemen. Needs help in configuration or negative clarifications on two issues. 1) First question whether is mixed use of cert/PSKsecrets auth possible? The same method (ether cert or PSKsecrets explicitly) serverside trough the parent [TLS] and inherited services works properly. But mixed cert/PSKsecrets like in config snippet below doesn't work. [TLS] client = no accept = 0.0.0.0:https connect = localhost:http cert = /etc/opt/stunnel/stunnel.pem [ssh] client = no sni = TLS:ssh connect = localhost:ssh [socks] client = no sni = TLS:socks protocol = socks PSKsecrets = /etc/opt/stunnel/auth/passwd The idea is to pass insensibly all incorrect or non-SNI aware requests to main http server and hide other multiplexed services. And at the same time to establish encryption and password access control to [socks] service. 2) And the second question is it possible proxy CONNECT after establishing SSL/TLS encryption? The configuration section: [ssh] accept = 22222 protocol = connect protocolHost = server.tld:443 protocolUsername = usernamehere protocolPassword = passwordhere connect = proxy.tld:8080 Say to establish unencrypted connection with proxy, pass username and password, tell proxy to establish CONNECT to target 443 and then transmit SSL/TLS to it. Goal is if I have SSL/TLS termination server/proxy on port 443 so we at first speak SSL/TLS with proxy and only then proceed to proxy requests phase. Thanks for future explanations.

installation problems
by HOFFMAN, GEOFFREY 30 Jan '17

30 Jan '17

I am having trouble installing stunnel on CentOS 7.3. I was given a directive to "use the latest OpenSSL" so on one target machine, it has 1.0.2k built from source. On the machine with OpenSSL 1.0.2k, when attempting to install stunnel, when I run ./configure, it passes with this info: configure: FIPS support not found Then make fails with: /usr/bin/ld: /usr/local/ssl/lib/libssl.a(s3_srvr.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC On another target machine, it has 1.0.1e-fips, installed via yum package. On the machine with OpenSSL 1.0.1e-fips, ./configure fails with: checking for TLS directory... not found configure: error: Could not find your TLS library installation dir Advice on installing with the latest OpenSSL (1.0.2k) would be much appreciated.
