AiX 7.1 TL3 SP6 - Stunnel Memory Usages grows after 24 hours
by Benjamin, Earl 19 Jul '16

19 Jul '16

Hello Everyone, I am running Stunnel-5.29 in AiX 7.1 TL3 SP6. I have added the DH param to the bottom of my CERT file. After approximately 24 hours or so the Stunnel CPU usage jumps to about 50% and after a few days to about 90%. Is there a configuration setting I've missed or compile option I need to consider? Thanks for your assistance in advance. Below is a cleaned up version of my config file. -Earl ------------------------------------------------- ; Verify peer certificate verify = 2 ; Certificate/key is needed in server mode and in client mode cert = /Server-certificate-all.pem key = /Server-certificate-all.pem CAfile = /all_root_ca.pem ; Protocol version (all, SSLv2, SSLv3, TLSv1) sslVersion = TLSv1 ; PID path pid = /etc/oraserver_stunnel.pid ; Turn off Nagle algorithm socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 ; Debug level debug = 2 ; Use it for client mode client = no ; Ciphers ciphers = DHE-RSA-AES256-SHA ; Service-level configuration [ oraserver_DB ] accept = 15210 connect = server:1622 [ oraserver_ASM ] accept = 15211 connect = server:1621 This message and any attachments are solely for the use of intended recipients.

Man in the middle attack possibility
by Abhinav Srivastava 19 Jul '16

19 Jul '16

Hi, I'm trying to use stunnel to provide encryption for my application to server communication. Server is already ssl aware. I configured my app to talk to localhost:xyz, and configured stunnel in client mode to relay traffic from localhost:<xyz> to actual service. The stunnel to service ssl protocol would use the server certificate, as server is already ssl aware. For any reason if stunnel is not running it would become possible for a non-elevated attacker/malware to spin up a tcp server listening to xyz, essentially taking advantage of my re-configuration of app to talk to localhost:xyz, and spoof the actual server. Even if my app to server protocol had some anti-spoofing mechanism say e.g., reverse CHAP, the malware can easily relay the challenge and response by using the actual service. In my case the actual app is iscsi initiator software that is not in my control and cant be modified, while the server is an iscsi tcp server which I am free to modify. Are there any guidance/best practices around preventing this attack with stunnel? Thanks Abhinav

Client certificates now required by default?

After building stunnel 5.34 from source I noticed that my old config (5.22) was not working.

stunnel and hosts.allow
by Yousef Alhashemi 05 Jul '16

05 Jul '16

Hi, This may be a little bit off-topic, but does anyone here use stunnel with pan? My connections to stunnel (in pan) are always refused by libwrap. I was looking for the right rule to add to /etc/hosts.allow but nothing seems to work aside from "ALL : ALL" (which is obviously not good) and "nntps: KNOWN". Is the latter reasonable? The hosts_access(5) manpage is confusing to say the least. It mentions that daemon (the first token on any line) is the name of the daemon running the process, which would be "stunnel" in my case, but using "stunnel : LOCAL" or even "stunnel : ALL" doesn't work. The rule that seems to work, as mentioned, is "nntps : KNOWN" ("nntps" being the group name in stunnel.conf). What's even more confusing to me is that "nntps : LOCAL" does not work either. Nor does "nntps : localhost 127.0.0.1", "nntps : localhost", "nntps : 127.0.0.1", or "nntps : 192.168.1.". Pan is running on the same machine as stunnel so all connections must be coming from localhost. Why do these rules not trigger? Either way, I'd like to know the "least permissive" hosts.allow rule that would allow me to connect to my news provider from pan, and/or whether "nntps : KNOWN" is a safe option. Thanks, Yousef

Failed to redirect http to https
by Doris Hongmei 27 Jun '16

27 Jun '16

Hi Support, I setup stunnel to a web server with apache Configuration like below, --- /usr/local/etc/stunnel/stunnel.conf ---------- ; It is recommended to drop root privileges if stunnel is started by root setuid = nobody setgid = nobody ; TLS front-end to a web server [https] accept = 443 connect = 127.0.0.1:80 cert = /usr/local/etc/stunnel/stunnel.pem --- end of /usr/local/etc/stunnel/stunnel.conf ---------- After stunnel started, https://xxx/ is working, http://xxx/ is also still working , which doesn't redirect to https://xxx automatically. As my understanding, all the connections from http should redirect to https through stunnel, right? What steps did I miss? I need your help. Thanks.

Re: [stunnel-users] FW: Stunnel with IIS8 on server 2012 64 bit
by J. Michael Drew 24 Jun '16

24 Jun '16

Jose, I have discovered what I did wrong. I did the original stunnel installs from the command line and then installed the stunnel service from the command line as well. When I installed the stunnel service it would break the website. So I removed the service (I thought) then I copied a shortcut to stunnel.exe to the Win start up> program folder. Both sites started working on the servers as long as I was logged in through an RDP session. I uninstalled everything and reinstalled. Stunnel 5.32 installs a Windows GUI on Server 2012 as well so I went back and used the Windows server 2012 desktop applications to install the windows service and to stop the GUI application. Everything is now working as expected. It appears that I was running two instances of stunnel at the same time and I didn’t completely remove the original stunnel service.

Subject: RE: [stunnel-users] FW: Stunnel with IIS8 on server 2012 64 bit Hi Jose, I made the changes you suggested, but I am still getting the same behavior. My external address is: https://website.company.com/website I am not adding any ports to the address. Thanks so much for your help! Michael From: Jose Alf. [mailto:[email protected]] Sent: Monday, June 20, 2016 12:10 PM To: J. Michael Drew; stunnel-users(a)stunnel.org Subject: Re: [stunnel-users] FW: Stunnel with IIS8 on server 2012 64 bit Michael, I guess what you want to do is to be able to connect to your internal Webserver via your Win2012 stunnel proxy using a URL like: https://yourwin2012dnsname:9001/ <https://yourwin2012dnsname:9009/> if that is correct, I suggest to adjust your configuration as follows: 1. Your stunnel mode must be server, not client. So adjust your service stanza as follows: [CLI9F529A0A] accept=9001 connect=10.xxx.xxx.xxx:9009 client=no 2. In your current configuration stunnel is listening only in the localhost ipv4 address (127.0.0.1). Therefore, you can only connect when you are logged on the server, you can't connect from a remote client. Hope this helps you clarify what's going on. Regards, Jose From: J.
